    REVIEW of a decision of the Court of Appeals.              Reversed and
    cause remanded.
    ¶1      ANNETTE KINGSLAND ZIEGLER, J.      This is a review of an
    unpublished decision of the court of appeals, State v. Iverson,
    No. 2014AP515–FT, unpublished slip op. (Wis. Ct. App. Oct. 9,
    2014), which affirmed the order of the La Crosse County circuit
    court1 granting defendant Daniel S. Iverson's ("Iverson") motion
    to suppress evidence of drunk driving obtained by an officer of
    the state traffic patrol during a traffic stop of Iverson's
    vehicle.
    1
    The Honorable Ramona A. Gonzalez presided.
    No.   2014AP515-FT
    ¶2    Iverson asserts that the officer lacked authority to
    seize Iverson's vehicle to investigate the violation of a state
    statute prohibiting littering, Wis. Stat. § 287.81 (2011-12).2
    Iverson    argues       in   the    alternative      that    the    officer    lacked
    probable cause or reasonable suspicion that a violation of the
    littering statute had occurred.
    ¶3    The central issue before us in this case is whether
    the   Fourth     Amendment     of    the    United    States       Constitution   and
    Article I, Section 11 of the Wisconsin Constitution permit an
    officer of the state traffic patrol to stop a vehicle based
    solely on the officer's observation of the commission of a non-
    traffic civil forfeiture offense by an occupant of that vehicle.
    ¶4    We conclude that: (1) the Wisconsin Legislature has
    explicitly authorized state troopers to conduct traffic stops in
    order to investigate violations of Wis. Stat. § 287.81 and to
    arrest violators of the statute under specified conditions; (2)
    a traffic stop to enforce § 287.81 is generally reasonable if an
    officer    has    probable      cause      or   reasonable     suspicion       that   a
    violation of § 287.81 has occurred; (3) discarding a cigarette
    butt onto a highway violates § 287.81; and (4) based on his
    observations, the officer in this case had probable cause to
    believe    that    an    occupant of        Iverson's       vehicle   had     violated
    § 287.81 by throwing a cigarette butt onto the highway.

    No.    2014AP515-FT
    ¶5      The defendant's motion to suppress evidence obtained
    during this traffic stop and to dismiss this case should have
    been denied.         We reverse the decision of the court of appeals
    and remand the case to the circuit court for reinstatement of
    charges and further proceedings consistent with this opinion.
    I.    FACTUAL BACKGROUND
    ¶6      On January 29, 2014, Wisconsin State Patrol Trooper
    Michael     Larsen    ("Trooper     Larsen")    testified     at    a     hearing   on
    Iverson's motion to suppress evidence.               The following facts are
    taken from his testimony.
    ¶7      On September 18, 2013, at about 1:00 a.m., Trooper
    Larsen was traveling northbound on Rose Street in the City of
    La Crosse.      He observed a silver jeep in front of him drift
    within its lane toward the centerline and back.                    The vehicle did
    not   cross    the    centerline     or   strike    the   curb.          The   vehicle
    approached an intersection secured by a flashing yellow traffic
    light.      Although there was no traffic at the intersection, the
    vehicle came to a complete stop at the light before continuing
    past the intersection.             The vehicle then arrived at a second
    flashing yellow light.            Again, despite a lack of traffic at the
    intersection, the vehicle stopped at the light before continuing
    north.      Trooper Larsen testified that at this point in time he
    did   not     feel    that    he    possessed      the    reasonable       suspicion
    necessary to conduct a traffic stop.3
    3
    We do not necessarily accept the officer's conclusion in
    this regard as our own. We need not address its soundness for
    purposes of analyzing the issues before the court.
    3
    No.    2014AP515-FT
    ¶8   Trooper Larsen then observed a cigarette butt "being
    thrown from the passenger side of the vehicle."               The cigarette
    butt hit the ground and scattered ashes across the right lane of
    the road.       After crossing an overpass, Trooper Larsen initiated
    a traffic stop of the vehicle.             Trooper Larsen testified that
    the reason for the stop was the ejection of the cigarette butt
    from the vehicle he had been following.              He relied upon Wis.
    Stat. § 287.81, entitled "Littering," which states in relevant
    part:
    [A] person who does any of the following                 may   be
    required to forfeit not more than $500:
    (a) Deposits or discharges any solid waste on or
    along any highway, in any waters of the state, on the
    ice of any waters of the state or on any other public
    or private property.
    (b) Permits any solid waste to be thrown from a
    vehicle operated by the person.
    Wis.    Stat.    § 287.81(2)(a)-(b).       Trooper   Larsen   informed     the
    driver of the vehicle, Iverson, that a cigarette butt had been
    thrown out of Iverson's vehicle.           Iverson denied knowledge, but
    the passenger admitted responsibility and stated that he had not
    known that the action was illegal.
    ¶9   Trooper Larsen eventually cited Iverson for operation
    of a motor vehicle while under the influence of an intoxicant,
    in violation of Wis. Stat. § 346.63(1)(a), and operation of a
    4
    No.   2014AP515-FT
    motor    vehicle    with    a    prohibited    alcohol    concentration,       first
    offense, in violation of § 346.63(1)(b).4
    II.   PROCEDURAL BACKGROUND
    ¶10       On October 17, 2013, Iverson pleaded not guilty to the
    violations alleged in the traffic citations he had received.                        On
    December 27, 2013, Iverson filed a motion to suppress any and
    all evidence obtained following the stop of his vehicle and to
    dismiss the case.       At the January 9, 2014 hearing on the motion,
    the La Crosse County circuit court granted Iverson's motion.
    The court stated:
    [Trooper Larsen] wasn't stopping [Iverson] to cite him
    for the litter. He was stopping him to see if he was
    a drunk driver. . . . The litter is the excuse, and if
    that cigarette butt comes out of the driver's side,
    I'm with you, Trooper . . . but not out of the
    passenger side.
    On January 14, 2014, the court entered an order granting the
    motion    to    suppress     evidence    and     to   dismiss    the   case.        On
    February 26, 2014, the State filed a notice of appeal.
    ¶11       On October 9, 2014, the court of appeals affirmed the
    circuit court's order on different grounds.                    It found that "an
    articulable      suspicion       or   probable    cause   of    violation      of    a
    forfeiture that is not a violation of a traffic regulation is
    [not] sufficient justification for a warrantless seizure of a
    citizen."       See State v. Iverson, No. 2014AP515-FT, unpublished
    slip op., ¶11 (Wis. Ct. App. Oct. 9, 2014).
    4
    The facts upon which Trooper Larsen based the citations
    are not at issue in this case.
    5
    No.    2014AP515-FT
    ¶12    In reaching its conclusion, the court of appeals first
    examined Wis. Stat. § 968.24, which it properly characterized as
    a   "legislative           codification"             of   Terry      v.     Ohio,          
    392 U.S. 1
    (1968).       Iverson, No. 2014AP515-FT, unpublished slip op., ¶6;
    see    State        v.     Post,     
    2007 WI 60
    ,   ¶11,       
    301 Wis. 2d 1
    ,       
    733 N.W.2d 634
    .          The statute authorizes law enforcement officers to
    conduct temporary questioning without arrest "when the officer
    reasonably suspects that such a person is committing, is about
    to commit or has committed a crime."                           Wis. Stat. § 968.24.
    ¶13    The court of appeals further noted that Wis. Stat.
    § 345.22 permits warrantless arrests for violations of traffic
    regulations.             Iverson, No. 2014AP515-FT, unpublished slip op.,
    ¶10.    The court of appeals reviewed our decision in State v.
    Popke, 
    2009 WI 37
    , 
    317 Wis. 2d 118
    , 
    765 N.W.2d 569
    , where we
    held   that     "[e]ven         if    no    probable           cause      exist[s],          a   police
    officer      may     still      conduct         a     traffic        stop       when,       under     the
    totality       of        the   circumstances,             he    or     she       has       grounds      to
    reasonably suspect that a crime or traffic violation has been or
    will be committed."                
    Id., ¶8 (quoting
    State v. Popke, 
    2009 WI 37
    ,    ¶23,    
    317 Wis. 2d 118
    ,          
    765 N.W.2d 569
    )           (emphases        added)
    (citation omitted).
    ¶14    Finally, the court of appeals quoted from one of its
    own decisions, State v. Krier, 
    165 Wis. 2d 673
    , 
    478 N.W.2d 63
    (Ct. App. 1991), in which it had held that where an individual's
    conduct might constitute either a civil forfeiture or a crime,
    depending      on        the   nature      of    the       conduct        and    on        whether    the
    individual         is     a    repeat       offender,          "[j]ust          as     there     is     no
    6
    No.        2014AP515-FT
    prohibition for stopping [an individual] because the behavior
    may end up being innocent, there is also no prohibition for
    stopping because the behavior may end up constituting a mere
    forfeiture."        
    Id., ¶12 (quoting
    State v. Krier, 
    165 Wis. 2d 673
    ,
    678, 
    478 N.W.2d 63
    (Ct. App. 1991)).
    ¶15      The court of appeals reasoned that, because littering
    in violation of Wis. Stat. § 287.81 is not a crime or traffic
    violation,5 neither           Terry, nor Wis. Stat.            § 968.24, nor Wis.
    Stat.      § 345.22,    nor    Popke     authorized       Trooper    Larsen's        stop.
    
    Id., ¶¶8-10, 13.
             Additionally, the court of appeals read the
    language in Krier to imply that conduct potentially resulting
    only in a "mere forfeiture" does not warrant a traffic stop.
    The     court     therefore      affirmed       suppression     of        the     evidence
    gathered by Trooper Larsen.            
    Id., ¶¶12, 14.
    ¶16      On December 19, 2014, the State filed a petition for
    review     in    this   court.      On    March     16,    2015,     we    granted      the
    petition.
    III.    STANDARD OF REVIEW
    ¶17      "Our review of an order granting or denying a motion
    to    suppress     evidence      presents       a   question    of    constitutional
    fact."       State v. Robinson, 
    2010 WI 80
    , ¶22, 
    327 Wis. 2d 302
    , 786
    5
    Compare Wis. Stat. § 287.81(2), (2m) (violation of
    littering statute punishable by forfeiture), with Wis. Stat.
    § 939.12 ("Conduct punishable only by a forfeiture is not a
    crime"), and Wis. Stat. § 345.20(1)(b) (defining "[t]raffic
    regulation" as "a provision of chs. 194 or 341 to 349 for which
    the penalty for violation is a forfeiture or an ordinance
    enacted in accordance with s. 349.06").

    probable cause or reasonable suspicion to stop a vehicle is a
    question of constitutional fact."                  Popke, 
    317 Wis. 2d 118

    fact,   this   court    engages     in    a    two-step   inquiry.          First,   we
    review the circuit court's findings of historical fact under a
    deferential    standard,       upholding       them   unless    they       are   clearly
    erroneous.          Second,    we      independently      apply       constitutional
    principles     to   those     facts."         Robinson,

    ¶19    This case also requires us to interpret and apply Wis.
    Stat.   § 287.81       and     other     relevant      statutes.            "Statutory
    interpretation and application present questions of law that we

    IV.     ANALYSIS
    ¶21     Iverson's citation for drunk driving gives rise to the
    issues before the court because he contends that the stop was in
    violation of his constitutional rights.                        Specifically, Iverson
    argues that the citations cannot stand because Trooper Larsen
    was    without    legal     authority      to    stop    Iverson's    vehicle    based
    solely upon violation of the littering statute, a non-traffic
    civil forfeiture law.             In addition, Iverson argues that                  the
    conduct upon which Trooper Larsen based the stop did not violate
    the littering statute.            In other words, we must address whether
    Trooper Larsen         was endowed with the legal authority to stop
    Iverson's vehicle after observing a cigarette butt being thrown
    onto a highway from the vehicle.                    Consequently, the focus of
    this    opinion    centers     upon       whether       this    conduct    constitutes
    "littering" so as to justify this traffic stop and whether this
    traffic stop can be based upon violation of this non-traffic
    civil forfeiture law.
    ¶22     As it relates to the constitutional issues now before
    this court, Iverson does not contend that he otherwise has a
    viable defense to the drunk driving charges.                      Similarly, he does
    not assert that we should undertake a traditional totality of
    the circumstances test so to evaluate whether his driving on
    that particular evening would otherwise justify a traffic stop.
    9
    No.     2014AP515-FT
    Indeed, if we were to analyze the totality of the circumstances
    of the stop at issue, we might not reach the question before the
    court,    and      that    analysis      would        only   serve       to     restate
    longstanding legal principles.             See, e.g., Post, 
    301 Wis. 2d 1
    ,
    ¶¶12-13; State v. Malone, 
    2004 WI 108
    , ¶¶21-24, 
    274 Wis. 2d 540
    ,
    
    683 N.W.2d 1
    .       Thus, we neither accept nor reject the officer's
    stated    belief    that    he   was     without      reasonable     suspicion      to
    conduct a traffic stop before the alleged littering occurred.
    ¶23     Our method of inquiry is shaped by a few important
    considerations.       First, Trooper Larsen, an officer of the state
    traffic patrol, stopped Iverson's vehicle in order to enforce
    Wis. Stat. § 287.81.        Second, Wis. Stat. § 110.07 delineates the
    powers and duties of officers of the state traffic patrol.                          And
    third, the automobile stop at issue must not be constitutionally
    unreasonable       under     the       circumstances.        See         Popke,     
    317 Wis. 2d 118
    , ¶11 (citation omitted).
    ¶24     Therefore,     in    order    to   determine     the     lawfulness      of
    Trooper    Larsen's       traffic      stop,     we     analyze    two        statutory
    questions and two constitutional questions: (1) whether throwing
    a cigarette butt onto a highway constitutes a violation of Wis.
    Stat. § 287.81; (2) whether Trooper Larsen possesses authority
    under Wis. Stat. § 110.07 to conduct warrantless traffic stops
    as a means of enforcing § 287.81; (3) whether a state traffic
    patrol officer may conduct a warrantless traffic stop based on
    probable cause or reasonable suspicion that a violation of a
    non-traffic civil forfeiture law has occurred; and (4) whether
    10

    Trooper Larsen possessed probable cause or reasonable suspicion
    that a violation of § 287.81 had occurred.
    A.     Statutory Authority to Conduct the Traffic Stop
    1.    Whether Throwing a Cigarette Butt onto a Highway
    Violates Wis. Stat. § 287.81
    ¶25       Iverson argues that throwing a cigarette butt onto a
    highway does not violate Wis. Stat. § 287.81.                    Although the
    statute prohibits the depositing or discharge of "solid waste"
    onto a highway, Iverson claims that a cigarette butt is not
    "solid waste" under the statute.           We disagree.
    ¶26       Wisconsin Stat. § 287.81 states in relevant part: "[A]
    person who does any of the following may be required to forfeit
    not more than $500:         (a) Deposits or discharges any solid waste
    on or along any highway . . . ."6          Wis. Stat. § 287.81(2)–(2)(a).
    ¶27       The definitional provision of the chapter within which
    Wis. Stat. § 287.81 falls defines "solid waste" as having "the
    meaning       given   in   s. 289.01(33)."      Wis.   Stat.     § 287.01(10).
    Wisconsin Stat. § 289.01(33) reads:
    "Solid waste" means any garbage, refuse, sludge
    from a waste treatment plant, water supply treatment
    plant or air pollution control facility and other
    discarded or salvageable materials, including solid,
    liquid, semisolid, or contained gaseous materials
    6
    "Highway" is defined in the statute as having "the meaning
    given in s. 340.01(22)." Wis. Stat. § 287.81(1)(am). Wisconsin
    Stat. § 340.01(22) in turn states in relevant part: "'Highway'
    means all public ways and thoroughfares and bridges on the same.
    It includes the entire width between the boundary lines of every
    way open to the use of the public as a matter of right for the
    purposes of vehicular travel." Wis. Stat. § 340.01(22).

    material in domestic sewage, or solid or dissolved
    materials in irrigation return flows or industrial
    discharges which are point sources subject to permits
    under ch. 283, or source material, as defined in
    s. 254.31(10), special nuclear material, as defined in
    s. 254.31(11), or by-product material, as defined in
    s. 254.31(1).
    Wis.    Stat.       § 289.01(33)      (emphasis        added).        "Garbage"        and
    "refuse" each also possess unique definitions.                        Garbage "means
    discarded     materials        resulting      from    the    handling,       processing,
    storage and consumption of food."                    § 289.01(9).      Refuse "means
    all matters produced from industrial or community life, subject
    to decomposition, not defined as sewage."                    § 289.01(28).
    ¶28    One could easily spend all day exploring Wis. Stat.
    § 289.01(33)'s various nooks and crannies, but we need not stop
    to     ponder        whether      cigarette          butts     are      "subject       to
    decomposition," § 289.01(28), or "result[] . . . from community
    activities," Wis. Stat. § 289.01(33), because cigarette butts
    manifestly constitute "other discarded . . . materials."
    ¶29    "Judicial deference to the policy choices enacted into
    law by the legislature requires that statutory interpretation
    focus primarily on the language of the statute.                       We assume that

    271 Wis. 2d 633

    rid   of     as     no    longer       useful,       valuable,        or     pleasurable."
    Webster's      Third      New      International        Dictionary           644     (1961).7
    Cigarette      butts        are     perhaps      a     paradigmatic              example     of
    "discarded" materials under this definition, as they are the
    abandoned remains of cigarettes, items that were once (at least
    to their users) useful, valuable, and pleasurable.
    ¶31     "Material," the singular of "materials," 
    id. at 1392,
    is a broad and indefinite word.                  One sense of the word, and the
    sense that we find most plausible here, is "the whole or a
    notable part of the elements or constituents or substance of
    something     physical . . . ."            
    Id. Viewed in
       isolation,          this
    definition clearly supports inclusion of cigarette butts within
    the       phrase     "discarded . . . materials."                     Nevertheless,           a
    nebulous term like "materials" draws meaning from its context,
    so we further analyze the passage to confirm the word's import.
    ¶32     Iverson points to the list introduced by the phrase
    "other      discarded . . . materials,            including"      and        asserts       that
    cigarette butts do not fall within any of the ensuing enumerated
    items.        But    even    if    a    cigarette       butt    did        not     constitute
    "solid . . . materials            resulting      from     industrial,            commercial,

    activities"——a proposition we find doubtful given consideration
    of the manufacture, sale, and use of cigarettes——the "including"
    clause   does      not    exhaust    the    possible       applications         of   "other
    discarded . . . materials."                See, e.g., Liebovich v. Minnesota

    ¶33    The       longstanding        canon     of     construction          "ejusdem
    generis" supports our analysis.                  This canon "instructs that when
    general words follow specific words in the statutory text, the
    general words should be construed in light of the specific words
    listed."     State v. Quintana,

    748 N.W.2d 447
             (citation       omitted).             The     specific      words
    "garbage," "refuse," and "sludge from a waste treatment plant,
    water supply treatment plant or air pollution control facility"
    do    not        so      limit      the     more      general           phrase       "other
    discarded . . . materials" that cigarette butts are of necessity
    excluded.         In     fact,   these     specific       terms       clarify    that    the
    definition encompasses more conventional items like cigarette
    butts.
    ¶34    The       definition    of    garbage,       for    example      ("discarded
    materials resulting from the handling, processing, storage and
    14
    No.     2014AP515-FT
    consumption       of      food,"      Wis.        Stat.        § 289.01(9)),        suggests
    inclusion    of       objects     such   as   fast        food      wrappers      and    paper
    napkins.     The definition of refuse ("all matters produced from
    industrial       or    community     life,    subject          to   decomposition,         not
    defined     as        sewage,"      § 289.01(28))          apparently           contemplates
    objects of both a specialized nature ("industrial" refuse) and
    of a more ordinary nature ("community life" refuse); into this
    latter category might fall objects such as newspapers and food
    waste, items likely found in vehicles throughout the state.                                The
    final    term,        "sludge,"     indicates       materials        of    a    specialized
    nature.     The statute's specific enumerations thus run the gamut
    from ordinary to specialized waste; they do not provide reason
    to omit cigarette butts from the broad category of "discarded
    materials."8
    ¶35    The        most   natural    reading          of    "other . . . discarded
    materials"       affords      the   definition       of        "solid     waste"    a    broad
    sweep, but it is not within our province to artificially limit
    the obvious reach of a statute without adequate reason.                                 "It is
    8
    Wisconsin Stat. § 287.05 establishes "policies of the
    state concerning the reduction of the amount of solid waste
    generated, the reuse, recycling and composting of solid waste
    and resource recovery from solid waste."      The first policy
    listed states "[t]hat maximum solid waste reduction, reuse,
    recycling, composting and resource recovery is in the best
    interest of the state in order to protect public health, to
    protect the quality of the natural environment and to conserve
    resources and energy." Wis. Stat. § 287.05(1) (emphasis added).
    Though the provision is not helpful in determining the meaning
    of "solid waste," we note that inclusion of cigarette butts
    within that definition serves these purposes.

    simply give effect to the statute's natural meaning.
    ¶36    At the circuit court, Iverson's attorney submitted an
    affidavit that stated in part:
    I have never in my legal experience had a call
    from or represented someone who was cited for
    littering or any other offense due to the throwing of
    a cigarette butt. In fact, I have witnessed hundreds
    of cigarette butts on the grounds outside our office,
    along the streets near our office and outside of
    taverns and other businesses located in downtown
    La Crosse and have never heard of anyone being cited
    for such disposal of cigarette butts.

    disposal     of    cigarette       butts      along   highways      is    somehow      a    de
    minimis offense under Wis. Stat. § 287.81, it fails to persuade.
    The   cumulative          effect      of    improper        waste    disposal         is     a
    demonstrable        example      of   why     littering     is     problematic.            The
    statement from the affidavit merely highlights the ills that the
    statute seeks to rectify by its plain terms.
    ¶37    In     any      event,        the     structure        of     the    statute
    demonstrates that the legislature could easily have created a
    quantitative threshold for the littering offense but did not.
    Wisconsin        Stat.    § 287.81(2m)        imposes   a    larger       forfeiture        of
    $1,000 on "a person who deposits any large item on or along any
    highway . . . ."            Wis.      Stat.      § 287.81(2m).      "Large       item"      is
    defined in the statute as "an appliance, an item of furniture, a
    tire, a vehicle, a boat, an aircraft, building materials, or
    demolition        waste."        § 287.81(1)(as).            The    legislature        thus
    considered quantity terms but did not set an amount necessary to
    trigger the statute, something the legislature has proven itself
    capable     of    doing     in   other     contexts.        See,    e.g.,      Wis.    Stat.
    §§ 348.15-348.16            (setting          pound-specific         vehicle          weight

    2. Whether Trooper Larsen is Statutorily Authorized
    to Conduct Traffic Stops to Enforce Wis. Stat. § 287.81
    ¶39   Iverson asserts that Trooper Larsen is without legal
    authority to effectuate this stop.        However, the plain meaning
    of Wis. Stat. § 110.07, "Traffic officers; powers and duties,"
    instructs otherwise.      The statute states in relevant part:
    Members of the state traffic patrol shall:
    1. Enforce and assist in the              administration
    of . . . [Wis. Stat. §] 287.81 . . . .

    stored or parked at any time to examine such vehicles,
    or to stop such vehicles while en route at any time
    upon the public highways to examine the same and make
    arrests for all violations thereof.
    Wis. Stat. § 110.07(1)(a)1., (a)3. (emphases added).
    ¶40   The   statute    further    grants   officers    of   the   state
    traffic patrol "the arrest powers of a law enforcement officer
    under [Wis. Stat. §] 968.07, regardless of whether the violation
    is punishable by forfeiture or criminal penalty."               Wis. Stat.
    § 110.07(2m).

    Wis. Stat. ch. 23, entitled "Conservation."         Specifically, Wis.
    18
    No.     2014AP515-FT
    Stat.      § 23.58    authorizes    "an   enforcing    officer"10        to    "stop   a
    person in a public place for a reasonable period of time when
    the officer reasonably suspects that such person is committing,
    is   about     to    commit   or   has    committed    a   violation          of   those
    statutes enumerated in s. 23.50(1)" and to "demand the name and
    address      of     the   person   and    an    explanation   of     the      person's
    conduct."         Wis. Stat. § 23.58.11        Wisconsin Stat. § 287.81 is one
    of the statutes enumerated in Wis. Stat. § 23.50(1).                      Wis. Stat.
    § 23.50(1).
    ¶42     Finally, Wis. Stat. §§ 23.56 and 23.57 provide certain
    authority to conduct arrests, both with and without warrants,
    for violations of the statutes listed in Wis. Stat. § 23.50(1).12

    "'Enforcing  officer' . . . means a   person   who  has
    authority to act pursuant to a specific statute."   Wis. Stat.
    § 23.51(3).
    11
    "Such a stop may be made only where the enforcing officer
    has proper authority to make an arrest for such violation," and
    "[s]uch detention and temporary questioning shall be conducted
    in the vicinity where the person was stopped."       Wis. Stat.
    § 23.58.    Additionally, the enforcing officer must identify
    himself or herself as such. 
    Id. 12 This
      authority   is  limited   by  various   conditions.
    Warrantless arrests in particular are authorized only where:
    (a) The person refuses to accept a citation or to
    make a deposit under s. 23.66; or
    (b) The person refuses to identify himself or
    herself satisfactorily or the officer has reasonable
    grounds to believe that the person is supplying false
    identification; or
    (c) Arrest is necessary to prevent imminent
    bodily harm to the enforcing officer or to another.

    ¶43    In    sum,    the    Wisconsin            Legislature    has     explicitly
    authorized state troopers to conduct traffic stops in order to
    investigate       violations      of   Wis.       Stat.    § 287.81    and    to     arrest
    violators of the statute under specified conditions.                               Trooper
    Larsen therefore possessed statutory authority to stop Iverson's
    vehicle upon witnessing the disposal of a cigarette butt onto
    the highway. Whether the stop was constitutionally reasonable,
    however, is the question to which we now turn.
    B.    Constitutional Authority to Conduct the Traffic Stop
    1.  Whether a State Traffic Patrol Officer May Conduct a
    Warrantless Traffic Stop Based on Probable Cause or
    Reasonable Suspicion that a Violation of a Non-Traffic
    Civil Forfeiture Law Has Occurred
    ¶44    A state traffic patrol officer's traffic stop of a
    vehicle is a "seizure" of "persons" under the Fourth Amendment.13
    See   Popke,      
    317 Wis. 2d 118
    ,        ¶11       (citations     omitted).        "An
    automobile        stop     must        not        be     unreasonable        under      the
    circumstances.          A traffic stop is generally reasonable if the
    officers have probable cause to believe that a traffic violation
    has occurred, or have grounds to reasonably suspect a violation
    has been or will be committed."                        
    Id. (citations and
    internal
    quotation marks omitted).              The issue before us is whether it is
    Wis. Stat. § 23.57(1)(a)-(c).

    Constitution's provision on search and seizure to be coextensive
    with the Fourth Amendment." State v. Houghton,

    reasonable       to     effectuate          a    stop     for     a    non-traffic     civil
    forfeiture offense.
    ¶45    The court of appeals below concluded that a traffic
    stop    may     not        be    premised       solely      on    a    non-traffic     civil
    forfeiture offense.               In other words, even if an officer observes
    a violation of the littering statute, the officer is without
    legal authority to stop the vehicle.                      Examining our statement in
    Popke that "a police officer may . . . conduct a traffic stop
    when, under the totality of the circumstances, he or she has
    grounds to reasonably suspect that a crime or traffic violation
    has been or will be committed,"                         Popke, 
    317 Wis. 2d 118
    , ¶23
    (emphases       added)          (citation       omitted),        the   court    of   appeals
    seemingly concluded that in order to so effectuate a stop, the
    officer      must     be    granted      specific       authority      under    Wis.   Stat.
    § 968.24 ("Temporary questioning without arrest" to investigate
    suspected criminal activity) or Wis. Stat. § 345.22 ("Authority
    to     arrest    without           a   warrant"       for    violations         of   traffic
    regulations).
    ¶46    The opinion of the court of appeals does not consider,
    however, whether Wis. Stat. § 110.07 ("Traffic officers; powers
    and    duties")       or        Wis.   Stat.     § 23.58     ("Temporary        questioning
    without arrest" to investigate suspected violations of certain
    enumerated statutes, including Wis. Stat. § 287.81), impact the
    analysis.14
    14
    Krier is not controlling for this reason. In Krier the
    court of appeals relied on Wis. Stat. § 968.24 for its
    definition of the permissible bounds of the police officer's

    21
    No.   2014AP515-FT
    ¶47   Under the court of appeals' interpretation, an officer
    would be required to sit idly by even if an individual threw an
    entire bag of garbage out of a vehicle's window, simply because
    littering is a non-traffic civil forfeiture offense.15     Neither
    Wis. Stat. § 968.24, nor Wis. Stat. § 345.22, nor Popke require
    this conclusion.   Although § 968.24 and § 345.22 pertain only to
    crimes and violations of traffic regulations, neither statute
    conduct.    E.g., State v. Krier, 
    165 Wis. 2d 673
    , 678, 
    478 N.W.2d 63
    (Ct. App. 1991) ("We hold that when a person's
    activity can constitute either a civil forfeiture or a crime, a
    police officer may validly perform an investigative stop
    pursuant to s. 968.24, Stats." (emphasis added)). In this case,
    however, Trooper Larsen derived his authority from Wis. Stat.
    § 110.07 and Wis. Stat. § 23.58. These statutes, in contrast to
    Wis. Stat. § 968.24, authorize traffic stops based on conduct
    punishable by civil forfeiture        alone.   See  Wis. Stat.
    § 110.07(1)(a)3.; Wis. Stat. § 23.58.

    Some might suggest that an officer who witnesses
    littering on the highway should get a warrant or issue a ticket
    in the mail, but one quickly sees how these are remedies in
    search of a problem.       First, the issuance of a littering
    citation is notably different from the issuance of, for example,
    a parking ticket; the latter is placed on a stopped vehicle and
    tracks the registered owner of the vehicle rather than the
    person who actually parked the car.         See, e.g., State of
    Wisconsin Department of Transportation, Division of Motor
    Vehicles, Unpaid Parking Tickets, Judgments and Towing and
    Storage Fees,    http://wisconsindot.gov/Pages/dmv/vehicles/prkg-
    tckt/unpaid-tickets.aspx    (last   visited   Sept.   30,   2015)
    (describing the Traffic Violation and Registration Program and
    noting that "[a]n authority issuing a parking ticket will send
    two notices to the registered owner of the vehicle").     Second,
    if an officer were relegated to such remedies, the officer would
    most likely be precluded from determining to whom a citation
    should be issued.    In effect, the officer would not be able to
    issue the ticket to the person who is responsible for the
    offense.   These approaches are ill-suited for a statute like
    Wis. Stat. § 287.81.

    forecloses traffic stops to enforce non-traffic civil forfeiture
    offenses.         Similarly,          while        Popke     analyzed     an    officer's
    authority    to    effectuate          traffic       stops     for    crimes     and    for
    violations of traffic regulations, Popke, 
    317 Wis. 2d 118
    , ¶¶23,
    28,   our    statement           in     Popke         that     "a     police      officer
    may . . . conduct a traffic stop when, under the totality of the
    circumstances, he or she has grounds to reasonably suspect that
    a crime or traffic violation has been or will be committed,"
    
    id., ¶23 (emphases
    added) (citation omitted), did not purport to
    circumscribe      the    universe      of     possible       scenarios     within      which
    traffic stops permissibly may occur, or to make such limits
    contingent on whether the legislature has titled a particular
    law a "traffic regulation."              The facts in Popke involved a stop
    based on criminal and traffic offenses, not a non-traffic civil
    forfeiture offense.          Thus, the language in Popke was limited to
    the issue then before the court.                   The question of whether a non-
    traffic civil forfeiture offense can justify a vehicular stop is
    before the court today.
    ¶48   Iverson      would    attach       constitutional           significance     to
    the legislature's categorization of civil forfeitures as either
    traffic-related         or   non-traffic-related,              with     the    effect    of
    limiting the ability of law enforcement officers to administer
    laws that the legislature saw fit to enact.                      But the legislature
    did not place any such limits on law enforcement.
    ¶49   Some civil violations, such as littering, can occur
    whether or not a vehicle is involved.                        Indeed, the legislature
    may have found characterization of Wis. Stat.                            § 287.81 as a
    23
    No.     2014AP515-FT
    "traffic regulation" improper simply because not all littering
    is done on the roads; the prohibition contained in the statute
    applies       to   all   areas    of    Wisconsin,       not    just       the   state's
    highways.          See   Wis.     Stat.       § 287.81(2)(a).              Perhaps    the
    legislature found it more appropriate to classify the littering
    offense as one pertaining to "Solid Waste Reduction, Recovery
    and Recycling," Wis. Stat. ch. 287, and group it with similar
    legislation, see Wis. Stat. ch 280 ("Pure Drinking Water"); Wis.
    Stat. ch. 285 ("Air Pollution") rather than with the traffic
    laws.       Whatever the reason for Wis. Stat. § 287.81's separation
    from    the    traffic    laws,     the   legislature          did   not     limit     the
    littering      statute    to     just   one    domain.         Instead,      the     broad
    language of the statute applies to Wisconsin's highways and the
    state traffic patrol has been given authority to enforce it
    under Wis. Stat. § 110.07(1)(a)1.16              The statute's classification
    as traffic-related or not does not by itself provide grounds for
    departure from our usual Fourth Amendment analysis.                          "We cannot

    We add that Wis. Stat. § 345.20, a provision setting out
    procedure governing "traffic forfeiture actions," makes specific
    mention of the littering statute. Wis. Stat. § 345.20 (emphasis
    added). Wisconsin Stat. § 345.20 provides that procedures set
    out in the "Conservation" chapter of the Wisconsin Statutes,
    Wis. Stat. ch. 23, "apply to actions in circuit court to recover
    forfeitures   for  violations   of  s. 287.81."      Wis.  Stat.
    § 345.20(g). At the same time, Wis. Stat. § 23.53 provides that
    the citation created within the "Conservation" chapter governs
    violations of certain statutes enumerated within that chapter,
    "except that the uniform traffic citation created under
    s. 345.11 may be used by . . . a traffic officer employed under
    s. 110.07 in enforcing s. 287.81." Wis. Stat. § 23.53(1).

    ¶50    If   we    otherwise      analyze       the   reasonableness           of    this
    traffic stop, not in terms of the traditional totality of the
    circumstances test based on Iverson's driving on the evening in
    question but, more abstractly, in terms of whether a traffic
    stop    for    littering        is     ever      reasonable,        we    arrive      at   the
    conclusion that such a stop is reasonable.                           See, e.g., Popke,
    
    317 Wis. 2d 118

    434 U.S. 106
    , 108-09 (1977).             We judge reasonableness in this context by
    "balanc[ing] . . . the              public       interest     and        the     individual's
    right to personal security free from arbitrary interference by

    Id., ¶30 n.6.
              After reviewing the decisions of the federal

    stops,       "weighed    against       the    public      interest       in   safe          roads,"
    warranted our conclusion.              See 
    id., ¶30. ¶53
        The    current       case     features       a   violation             of     a   law
    applicable to the state's highways and statutorily enforceable
    by     the    state's        traffic    patrol.           Enforcement            of        the   law
    conceivably helps keep the state's roads safe.17                           In addition, we
    note that the legislature has specifically defined the terms
    according       to    which        officers     may       briefly     detain           potential
    violators of Wis. Stat. § 287.81.                     Our approval of the traffic
    stop    at    issue     is    therefore       not    at     odds    with      Houghton.            A
    reasonable suspicion that a violation of the littering statute,
    § 287.81, has occurred justifies a brief and limited traffic
    stop.        The more onerous standard of probable cause would also
    therefore       justify        a     traffic        stop.          See     Houghton,             
    364 Wis. 2d 234
    , ¶21.
    17
    In its brief before this court, the State asserted that
    littering creates hazards for other motorists and that discarded
    lit cigarettes in particular can cause brush, grass, and forest
    fires leading to property damage.      These dangers are self-
    evident and at least as serious as many of the interests with
    which Wisconsin's traffic-related civil forfeiture laws are
    apparently   concerned.     See,  e.g.,   Wis.   Stat.  § 341.04
    (prohibiting the operation of an unregistered or improperly
    registered vehicle); Wis. Stat. § 346.20(1) (requiring vehicle
    operators to yield the right-of-way at intersections to vehicles
    in funeral processions when the latter have their headlights
    lighted); § 346.29(3) (unlawful to use certain bridges for
    fishing).

    enforce civil forfeiture laws per se unconstitutional, even when
    those laws are not technically "traffic regulations."       As we
    intimated in Popke, this court has no authority to decide which
    laws "are sufficiently important to merit enforcement."        See
    Popke, 
    317 Wis. 2d 118

    Whren, 517 U.S. at 819

    In Nelson we "note[d] that it has long been established
    in Wisconsin" that law enforcement officers generally may make
    warrantless arrests upon probable cause for ordinance violations
    occurring in the presence of officers.     City of Milwaukee v.
    Nelson, 
    149 Wis. 2d 434
    , 458, 
    439 N.W.2d 562
    (1989) (citation
    omitted).   Wisconsin Stat. § 110.07 once contained such an "in
    presence" requirement.   See Wis. Stat. § 110.07(2m) (1971-72).
    However, the legislature later eliminated this requirement, see
    Wis. Stat. § 110.07 (1973-74), and today officers of the state
    traffic patrol possess "the arrest powers of a law enforcement
    officer under [Wis. Stat. §] 968.07, regardless of whether the
    violation is punishable by forfeiture or criminal penalty."
    Wis. Stat. § 110.07(2m) (2011-12). We do not address today what
    the elimination of that requirement may mean, given that the
    violation here occurred in the officer's presence. See Atwater
    v. City of Lago, 
    532 U.S. 318
    , 340 n.11 (2001) (declining to
    speculate on "in presence" requirement for misdemeanor arrests,
    but quoting statement of dissent in Welsh v. Wisconsin, 
    466 U.S. 740
    , 756 (1984) (White, J., dissenting), that "the requirement
    that a misdemeanor must have occurred in the officer's presence
    to justify a warrantless arrest is not grounded in the Fourth
    Amendment").

    ¶55     We conclude that a traffic stop to enforce Wis. Stat.
    § 287.81    is    generally       reasonable    if     an   officer     has      probable
    cause or reasonable suspicion that a violation of § 287.81 has
    occurred.

    but rather, probable cause requires that 'the information lead a

    Although we rely on Trooper Larsen's testimony regarding
    the reason for the traffic stop, this opinion should not be read
    to exclude a traffic stop based upon the conduct that Trooper
    Larsen witnessed prior to his observation of the disposal of the
    cigarette butt. In other words, Trooper Larsen might well have

    based on his observations, Trooper Larsen had probable cause to
    believe   that   an   occupant20   of    Iverson's        vehicle     had     violated
    § 287.81 by throwing a cigarette butt onto the highway.
    ¶59    Because    Trooper   Larsen's          traffic   stop     was     based   on
    probable cause, we need not consider whether he also possessed
    reasonable suspicion that a violation of the littering statute
    had occurred.
    V.    CONCLUSION
    ¶60    We conclude that: (1) the Wisconsin Legislature has
    explicitly authorized state troopers to conduct traffic stops in
    possessed probable cause or reasonable suspicion to conduct a
    traffic stop at this point in time. Cf. State v. Post,

    need not be erratic, unsafe, or illegal to give rise to
    reasonable suspicion.").
    20
    Despite Iverson's suggestions to the contrary, the
    question of who threw the cigarette butt out of the vehicle is
    not relevant to our determination today. For a traffic stop to
    be lawful as to all occupants, "[t]he State need not establish
    that the police had reasonable, articulable suspicion to seize
    the particular defendant before the court, but only that the
    police possessed reasonable, articulable suspicion to seize
    someone in the vehicle." State v. Harris,

    order to investigate violations of Wis. Stat. § 287.81 and to
    arrest violators of the statute under specified conditions; (2)
    a traffic stop to enforce § 287.81 is generally reasonable if an
    officer    has   probable     cause   or   reasonable      suspicion      that    a
    violation of § 287.81 has occurred; (3) discarding a cigarette
    butt onto a highway violates § 287.81; and (4) based on his
    observations, Trooper Larsen had probable cause to believe that
    an   occupant    of    Iverson's   vehicle      had    violated      § 287.81    by
    throwing a cigarette butt onto the highway.

    during this traffic stop and to dismiss this case should have

    In granting Iverson's motion, the circuit court suggested
    that violation of the littering statute was Trooper Larsen's
    "excuse" for stopping Iverson's vehicle.        But "pretextual
    traffic stops . . . are not per se unreasonable under the Fourth
    Amendment."    Houghton,

    "of little concern." See State v. Kramer,

    ¶65       The   majority   opinion       explains    how    it    analyzes     the
    reasonableness of the automobile stop in the instant case: "not
    in terms of the traditional totality of the circumstances test

    vehicle    stop   case,   the   underlying    offense   is    ordinarily    a
    criminal or traffic violation.           The public interest is high in
    such a case.      Public safety is ordinarily at risk by criminal
    behavior or a violation of traffic laws.11          The public interest
    in stopping the vehicle in the instant case is comparatively
    low; there is no evidence that throwing a single cigarette butt
    from Iverson's car created any hazard.          In the case of a civil,
    non-traffic, forfeiture offense (like littering), the state's

    of movement and is inconvenient, time-consuming, and anxiety-
    inducing.     Moreover, a vehicle stop provides a law enforcement

    For an example of the United States Supreme Court's

    The seriousness of the underlying offense is also relevant

    contexts. See United States v. Griggs,

    ¶70    For this reason, some courts have declined to extend
    the   general    reasonable       suspicion      standard    in     striking       the

    vehicle stops for extremely minor infractions, such as a parking

    ¶71    The majority opinion suggests that "the issuance of a
    littering citation is notably different from the issuance of,
    for   example,    a   parking    ticket,"     because     parking       tickets    are
    placed on a stopped vehicle and track the registered owner,
    while a littering citation is issued to the litterer.15                        True,
    but   constitutionally      not      relevant.      There     is    a    similarity
    between stopping a vehicle for littering and stopping a moving
    vehicle for an observed parking violation.                   In both instances

    the intrusion of having the vehicle stopped remains the same as
    in any other vehicle stop.
    ¶72     When an officer has reasonable suspicion to issue a
    parking ticket or a littering citation, in the absence of some
    public safety risk or other significant public interest, the
    public interest in issuing the citation does not automatically
    overcome an individual's right to be free from the intrusion of
    having the vehicle stopped.
    ¶73     This distinction between an infraction that does and
    does not present a public safety risk or otherwise violate a
    significant public interest is illustrated by several examples
    on which the majority opinion relies.                  The majority opinion
    illuminates    that   "discarded       lit    cigarettes   in    particular    can
    cause     brush,   grass,   and    forest      fires   leading     to    property
    damage."16     The majority opinion also explains that throwing a
    large bag of trash out of a moving vehicle is dangerous to
    others who use the road.17
    ¶74     The   examples       in    the     majority    opinion       suggest
    circumstances that would be relevant under a totality of the
    circumstances      analysis.      A    cigarette    butt   thrown       out   of   a
    vehicle in a dry, fire-prone area may very well pose a risk to
    public safety and the environment.             No such danger by the single
    cigarette butt in the instant case is alleged.                      Ash from a

    cigarette likely poses no danger at all.18                A trash bag thrown
    out of a moving vehicle obviously may very well pose a danger to
    other motorists; a single cigarette butt ordinarily does not.
    These examples flesh out the totality of circumstances to be
    considered.
    ¶75   In the instant case, no proof of a public safety risk
    was   offered.     Iverson    was   driving    in   the   wee    hours   of   the
    morning in the city of La Crosse.             There is no evidence in the
    record suggesting that other drivers on the road were somehow
    endangered    by   the   passenger's   tossing      a   cigarette    butt,    let
    alone that there was a risk of fire, property damage, or other
    significant danger as a result of the discarded cigarette.
    ¶76   Rather, the traffic stop in this case is a variation
    on familiar themes.          The trooper stopped Iverson based on a
    minor violation, here littering.           See Wis. Stat. § 287.81.           The
    stop was pretextual.       The trooper's true motive was not to issue
    a citation for littering, but to investigate a more serious
    traffic offense or potentially criminal offense, namely drunk
    driving.      The trooper saw Iverson's vehicle driving late at
    night and began following the vehicle.                  The trooper saw the
    vehicle drift within its lane and stop at two flashing yellow
    lights despite the absence of traffic.
    ¶77   The trooper evidently had a hunch that the driver was
    intoxicated (and his hunch was apparently correct).                 The trooper

    concluded, however, that he did not have reasonable suspicion to
    stop the vehicle.19        Then came the "a-ha" moment.                 When the
    trooper saw a cigarette butt thrown from the passenger side of
    the vehicle, the trooper concluded that he had grounds to stop
    the vehicle.
    ¶78     Underscoring    the     pretextual      nature      of     the   stop,
    neither   Iverson    nor   his    passenger   was    cited      for    littering.
    Instead, Iverson was arrested for drunk driving.
    ¶79     The circuit court relied on the pretextual nature of
    the stop in granting the motion to suppress.                    However, under
    Whren v. United States, 
    517 U.S. 806
    , 813 (1996), and other
    cases,    the   constitutional     reasonability     of   a     stop    does   not

    and stopping at flashing yellow lights constitute reasonable
    suspicion of drunk driving.      Majority op., ¶7 n.3.      That

    depend    on     the    subjective    motivations    of      the     officer.20
    Pretextual stops have been accepted under the Fourth Amendment.
    ¶80     In the instant case the dominant factors to gauge in
    assessing      the   reasonableness   of   the   vehicle     stop    under   the
    totality of the circumstances can be summarized as follows: the
    public interest in this particular stop for littering was slight
    or insubstantial; a vehicle stop is a significant intrusion on a
    person's security; the statutory violation was flimsy; and the
    reason for the vehicle stop was pretextual.           This combination of
    circumstances, had the case been presented this way, might lead
    me to conclude that the vehicle stop was not reasonable under
    the Fourth Amendment.
    ¶81     I caution that the majority opinion should not be over
    read.    I do not think the majority intends its opinion to be
    read as granting law enforcement officers extraordinarily broad
    powers to stop vehicles without meaningful judicial review.
    ¶82     In sum, the traditional Fourth Amendment rules still
    apply in Wisconsin.       The Fourth Amendment prohibits unreasonable
    20
    This rule has been criticized.     See, e.g., 1 Wayne R.
    LaFave, Search & Seizure: A Treatise on the Fourth Amendment,
    § 1.4(f) (5th ed. 2012) (critiquing Whren v. United States,

    742 N.W.2d 923
    (Ct. App. 2007) ("We note that the
    officer's subjective motivation for making a stop is not the
    issue; if the officer has facts that could justify reasonable
    suspicion (or probable cause), it is of no import that the
    officer is not subjectively motivated by a desire to investigate
    this suspicion.   We question the wisdom of this rule when it
    comes to extremely minor traffic violations, but that is for
    another day.") (internal citations omitted) (citing Whren v.

    searches     and   seizures.21      Reasonableness      is   gauged      under   the
    totality of the circumstances.22             "An automobile stop must not be
    unreasonable under the circumstances."23
    ¶83    Reasonableness       depends     on   a   court's     balancing     the
    public      interest   against     an   individual's      right     to    personal
    security free from interference by law enforcement.                   In striking
    this balance, a court must carefully scrutinize the totality of
    the circumstances.        Unfortunately, the majority opinion did not
    apply these rules.        I therefore write separately.
    ¶84    Before I conclude, however, I add a comment about the
    statutes applicable in the instant case.                The statutes at issue
    are   part    of   Wis.   Stat.    chapter     287,    entitled     "Solid   Waste
    Reduction, Recovery and Recycling."
    ¶85    Wisconsin     Stat.    § 287.81(2),       entitled      "Littering,"
    provides that a person who "[d]eposits or discharges any solid
    waste on or along any highway" or "[p]ermits any solid waste to

    ¶86    Section 287.01(10) adopts the meaning of "solid waste"
    set forth in Wis. Stat. § 289.01(33).25               The definition of "solid
    waste"    lists       many   materials,      including    garbage,          refuse,   and
    materials resulting from "community activities."26                          "Refuse" is
    defined    in     part       as   "matters     produced       from     industrial      or
    community life."27
    ¶87    The phrases "community activities" and "produced from
    industrial      or     community       life"   defy   almost         any     effort    at
    definition.
    ¶88    Would       a    simpler    littering     statute        not     intimately
    connected with solid waste suffice, so a court need not spend 14
    paragraphs,       9    double-spaced      pages,    and   a    lot     of    dictionary
    research for a discourse on whether a cigarette butt violates
    the littering statute?              "Littering" is a word in common usage,
    with a generally accepted meaning, but the word "littering" is
    not used in chapter 287 other than in the title to subchapter IV
    of chapter 287 and the title of Wis. Stat. § 287.81.
