    STATE v. JAMES KENNETH WATSON, (A144832) (S060351), Walters, J., Defendant
    filed a motion to suppress evidence seized pursuant to an officer’s search of his car, claiming
    that the intensity and duration of the stop exceeded its legal basis in violation of Article I,
    section 9, of the Oregon Constitution. The trial court denied the motion, and the Court of
    Appeals affirmed without opinion. Held: The officer’s activities were either reasonably related
    to the investigation of the traffic infraction, did not lead to the discovery of the evidence that
    defendant sought to suppress, or were justified by reasonable suspicion of criminal activity and
    probable cause that the officer developed during the course of the stop.
    The decision of the Court of Appeals and the judgment of the circuit court are affirmed.

    WALTERS, J.
    In this criminal case, we consider whether a police
    officer violated Article I, section 9, of the Oregon Constitution
    when, after lawfully stopping defendant to investigate a
    traffic violation and deciding not to issue him a citation,
    the officer continued to detain defendant, conducted further
    investigation, and discovered evidence that defendant
    possessed a controlled substance. We conclude that the
    officer’s request for defendant’s driver’s license, and his brief
    detention of defendant pending verification of defendant’s
    driving privileges, were reasonably related to the officer’s
    investigation of the traffic violation and were therefore
    lawful. We also conclude that the officer’s other investigatory
    activities were reasonably related to the purpose for the
    stop or, even if they were not, either did not lead to the
    production of the incriminating evidence that defendant
    sought to suppress or were justified on other grounds. We
    therefore hold that the trial court did not err in denying
    defendant’s motion to suppress, and we affirm the decision
    of the Court of Appeals.
    In reviewing the denial of a motion to suppress, we
    are bound by the trial court’s findings of historical fact to
    the extent that those findings are supported by evidence in
    the record. State v. Stevens, 
    311 Or 119
    , 126, 806 P2d 92
    (1991). If the trial court did not make express findings, as
    is the case here, we presume that the trial court found facts
    that were consistent with its ultimate conclusion. 
    Id. at 127
    .
    We observe that standard in stating the facts that follow. We
    then address the parties’ legal arguments concerning the
    limitations imposed by Article I, section 9, and how those
    limitations apply to the facts.
    On the evening of April 21, 2008, Officer Kris Malek of
    the Myrtle Creek Police Department saw a car cross over the
    yellow line that divided the north- and south-bound lanes of
    traffic. Malek stopped the car and immediately recognized
    defendant, who was sitting in the driver’s seat. Malek knew
    defendant from previous traffic stops and from interacting
    with him socially. Approximately two months prior to the
    traffic stop at issue in this case, Malek had heard rumors
    770	                                          State v. Watson
    that defendant was dealing small amounts of marijuana
    around the city of Myrtle Creek.
    When Malek informed defendant that he had stopped
    him for failure to maintain a lane, defendant responded that
    he had dropped his cell phone and had drifted into oncoming
    traffic when he reached down to retrieve it. Although Malek
    could have issued defendant a citation, he decided to give
    defendant a warning instead. Nevertheless, Malek asked
    for defendant’s driver’s license, registration, and proof of
    insurance. Defendant complied, and Malek called dispatch
    and requested records and warrants checks pursuant to his
    routine practice. Malek always detains drivers whom he has
    stopped for traffic violations until dispatch confirms that
    the driver in question has a valid license. Dispatch usually
    takes between four and 10 minutes to return the results of
    the checks.
    Malek usually returns to his car and waits for
    dispatch to return the results of the records and warrants
    checks. In this case, however, because he had had so many
    friendly dealings with defendant in the past and did not
    feel that defendant was “a threat,” Malek “had no problem
    standing at [defendant’s] vehicle while waiting for a return
    from dispatch.” In addition, Malek had “wanted to have a
    conversation with [defendant] about what [Malek had] been
    hearing in the community.” With that purpose in mind,
    Malek asked defendant if he would step out of his car.
    Defendant complied, leaving the driver’s side door ajar. Malek
    told defendant that he had heard rumors that defendant
    was dealing small amounts of marijuana. Defendant denied
    that allegation. The conversation “progressed,” and Malek
    asked defendant for consent to search his car. Defendant
    refused and began to “yell” at Malek.
    At that point, Deputy Clayton Ruble “came upon” the
    traffic stop, got out of his car, and approached the passenger
    side of defendant’s car. Ruble informed Malek that he could
    smell “a pretty strong odor” of marijuana emanating from
    the partially-open window of defendant’s car. Malek then
    stepped into the space created by the open driver’s side door
    of the car, took “a big sniff,” and also smelled “what, through
    Cite as 
    353 Or 768
     (2013)	771
    training and experience, [he] believe[d to be] marijuana
    coming from the vehicle.” Malek contacted Probation Officer
    Hooly, accompanied by a drug-detection dog, to respond to
    the scene. While they waited, Malek and Ruble continued
    to question defendant. They asked him whether he had
    marijuana inside his car, and he responded that he had
    “approximately an eighth of an ounce.” Officer Hooly then
    arrived, walked her dog around the car, and observed that
    the dog “hit on the vehicle,” indicating the presence of a
    controlled substance.
    At that point, Malek believed that he had probable
    cause to search defendant’s car. He reached inside the open
    passenger side window and retrieved a backpack that was
    sitting on the passenger seat. Inside, he found marijuana,
    cocaine, and various drug-related paraphernalia. Malek
    placed defendant under arrest. A short time later, Malek
    received a call from dispatch that defendant’s drivers
    license was valid and that there were no outstanding
    warrants for his arrest. The entire stop, from its inception
    until Malek arrested defendant and received the return
    call from dispatch, lasted approximately 10 minutes.1 All
    of the actions that Malek and Ruble took occurred during
    the 10-minute period that the records and warrants checks
    were pending.
    Defendant filed a motion to suppress all property
    seized pursuant to Malek’s search of his vehicle, claiming
    that the stop’s “intensity and duration” exceeded its legal
    basis. During the hearing on that motion, defendant argued
    that, although the officers had detained him for only 10
    minutes, the police actions that occurred during that
    detention—in particular, Malek’s drug-related questioning,
    his requests that defendant exit his car and consent to search,
    his use of the drug-detection dog, and his eventual search
    of defendant’s car—constituted a criminal investigation
    that expanded the scope of the initially lawful stop beyond
    constitutional bounds. Without reasonable suspicion of an
    1
    There is no evidence in the record whether the records and warrants checks
    are separate checks and, if so, disaggregating the time it took to conduct the records
    check versus the warrants check. The record states only that Malek requested that
    dispatch conduct both of those checks and that dispatch returned the results of
    both checks 10 minutes later.
    772	                                                        State v. Watson
    additional infraction or crime, defendant argued, an officer’s
    authority is strictly limited to a reasonable investigation of
    the traffic infraction that initially prompted the stop.2
    The state responded that Malek was permitted to
    question defendant concerning matters that were unrelated
    to the stop, even if Malek had lacked reasonable suspicion
    to believe that defendant was engaged in criminal activity,
    as long as that questioning did not unreasonably prolong
    the stop’s duration. The trial court denied defendant’s
    motion without any explicit statement of its reasoning,
    and defendant was convicted of delivery and possession of
    marijuana and cocaine.
    Defendant appealed and the Court of Appeals affirmed
    without opinion. State v. Watson, 
    249 Or App 179
    , 276 P3d
    1126 (2012). Defendant petitioned for review, and we allowed
    review to address the constitutional limits on police action
    during the course of a lawful traffic stop.
    Before this court, defendant renews and refines his
    arguments. He first argues that, after Malek pulled him
    over and received facially-valid documents, Malek had
    “everything that he needed” to complete his investigation
    of the traffic violation. The records and warrants checks,
    and the additional detention that accompanied them,
    thus constituted an independent investigation into other
    wrongdoing that exceeded both the lawful duration and
    scope of the stop.3 Defendant proposes, as a rule, that,
    unless the nature or condition of a driver’s documents
    gives an officer a reasonable basis to believe that the driver
    has committed another traffic violation in connection
    with those documents, the officer lacks any justification
    to detain the driver or to conduct further investigation.4
    2
    Defendant also argued that Malek lacked reasonable suspicion of criminal
    activity even after smelling the marijuana and that the search of defendant’s
    vehicle for an infraction quantity of marijuana could not be justified under the
    automobile exception to the warrant requirement. Defendant did not advance
    those arguments on appeal.
    3
    Defendant focuses his argument on the officer’s authority to seize him and
    on the constitutional scope of that seizure. He does not explicitly and separately
    argue that the records and warrants checks constituted searches that were
    unsupported by probable cause. We therefore do not address that issue.
    4
    At oral argument, defense counsel clarified that he was not necessarily
    arguing that officers lack the authority to run records and warrants checks on
    Cite as 
    353 Or 768
     (2013)	773
    Defendant then argues that even if Malek’s detention of
    defendant during the records and warrants checks was
    constitutionally permissible, Malek engaged in “additional
    shows of authority” that unconstitutionally extended the
    scope of the initially lawful stop. Defendant argues that,
    because the incriminating evidence was discovered either
    during Malek’s illegally extended seizure of defendant or as
    a result of his “illegally enhanced seizure” of defendant, that
    evidence should be suppressed in order to restore defendant
    to the position that he would have held but for the illegality.
    The state counters that an officer’s records and warrants
    checks always are reasonably related to the investigation of
    a routine traffic violation or are justified under the officer
    safety doctrine, and that Malek’s actions during the stop
    did not rise to the level of an additional seizure because a
    reasonable person would not have believed that his liberty
    was restrained beyond what was entailed by the traffic stop
    itself.5
    Article I, section 9, of the Oregon Constitution
    establishes the right of the people “to be secure in their
    persons, houses, papers, and effects, against unreasonable
    search, or seizure.”6 That provision imposes limitations on
    searches and seizures “in order to prevent arbitrary and
    oppressive interference by [law] enforcement officials with
    the privacy and personal security of individuals.” State v.
    Tourtillott, 
    289 Or 845
    , 853, 618 P2d 423 (1980) (quoting
    United States v. Martinez-Fuerte, 
    428 US 543
    , 554, 
    96 S Ct 3074
    , 
    49 L Ed 2d 1116
     (1976)).
    drivers stopped for traffic violations. Rather, he argued that officers lack the
    authority to detain drivers while they do so. That assertion is contrary to his brief,
    in which he explicitly argues that the records and warrants checks themselves
    must be supported by additional reasonable suspicion. Because the arguments
    concerning the scope and the duration of the checks are interrelated, we address
    both.
    5
    On review, the state does not argue that Malek had reasonable suspicion
    that defendant had illegal drugs in his car that would have justified a stop of
    defendant on that basis.
    6
    Article I, section 9, of the Oregon Constitution provides:
    “The right of people to be secure in their persons, houses, papers, and
    effects, against unreasonable searches and seizures, shall not be violated,
    and no Warrants shall issue, but upon probable cause, supported by Oath
    or affirmation, and particularly describing the place to be searched, and the
    persons or things to be seized.”
    774	                                                         State v. Watson
    Police encounters with individuals generally fall
    into one of three categories. State v. Fair, 
    353 Or 588
    , 593,
    __ P3d __ (2013) (so explaining); see also State v. Holmes,
    
    311 Or 400
    , 406-07, 813 P2d 28 (1991) (same). At one end
    of the continuum are “non-coercive encounter[s]” between
    an officer and an individual, which involve no restraint
    of liberty and thus require no justification. Holmes, 
    311 Or at 407
    . At the other end are arrests, which involve
    protracted custodial restraint and require probable cause
    to believe that the person arrested has committed a crime.
    Fair, 353 Or at 593. In between are “stops,” which involve
    a temporary restraint on a person’s liberty through either
    physical force or some other “show of authority.” State v.
    Ashbaugh, 
    349 Or 297
    , 308-09, 244 P3d 360 (2010) (citing
    State v. Rodgers/Kirkeby, 
    347 Or 610
    , 621-22, 227 P3d 695
    (2010)). Although both arrests and stops are seizures for
    constitutional purposes, an officer may stop an individual
    based on reasonable suspicion of criminal activity—a lower
    standard than the probable cause that is required for an
    arrest. Fair, 353 Or at 593-94. An officer who lacks probable
    cause to arrest but who has either reasonable suspicion of
    criminal activity or probable cause to believe that a driver
    has committed an unlawful but noncriminal act, such as a
    traffic violation, may require the driver to pull over so that
    the officer can investigate further.7 Such an interaction is a
    stop and a seizure for Article I, section 9, purposes, rather
    than a “non-coercive encounter,” because
    “in contrast to a person on the street, who may unilaterally
    end an officer-citizen encounter at any time, the reality is
    that a motorist stopped for a traffic infraction is legally
    obligated to stop at an officer’s direction * * * and to interact
    with the officer * * * and therefore is not free unilaterally to
    end the encounter and leave whenever he or she chooses.”
    Rodgers/Kirkeby, 
    347 Or at 622-23
     (internal citations
    omitted).
    7
    The requirement that an officer have probable cause to believe that a driver
    committed a traffic violation is a statutory requirement. Whether that requirement
    also is found in Article I, section 9, is a question that this court has reserved.
    State v. Matthews, 
    320 Or 398
    , 402 n 2, 884 P2d 1224 (1994). We need not decide
    that question in this case, because on review, defendant does not contest Malek’s
    justification to effect the stop.
    Cite as 
    353 Or 768
     (2013)	775
    In the case before us, Malek’s stop of defendant
    was lawful at its inception. Although Malek lacked probable
    cause to arrest defendant, he had probable cause to believe
    that defendant had committed a noncriminal traffic
    violation. Article I, section 9, permitted Malek to stop and
    detain defendant briefly for the purposes of investigation.8
    The central issue to which we now turn is the limits that that
    constitutional provision places on police conduct during the
    course of a lawful traffic stop and whether Malek’s activities
    exceeded those limits.
    This court has not often considered the constitu-
    tional limits on police activity during lawful traffic stops
    due,in part, to the role that Oregon statutory law has
    played in its analysis. Soon after the United States
    Supreme Court decided Terry v. Ohio, 
    392 US 1
    , 
    88 S Ct 1868
    , 
    20 L Ed 2d 889
     (1968), in which the Court held that
    police officers did not violate the Fourth Amendment to the
    United States Constitution when they stopped and frisked
    the defendant, the Oregon legislature enacted statutes
    that were responsive to that ruling. Terry permitted officers
    with reasonable suspicion that a person was involved in
    criminal activity and might be armed or dangerous to
    stop that person, make “reasonable inquiries,” and conduct
    a limited “patdown” search for weapons. 
    Id. at 30
    . In State
    v. Cloman, 
    254 Or 1
    , 7, 456 P2d 67 (1969), this court
    borrowed the reasoning from federal Fourth Amendment
    juris-prudence and adopted it for the purposes of Article I,
    section 9. See Fair, 353 Or at 602-03 n 7 (so explaining).
    The court held that the limited detention of criminal
    suspects based on particularized reasonable suspicion was
    constitutional, recognizing that such stops were required
    by the “practical necessities of effective law enforcement”
    and emphasizing that a “brief, informal” detention for
    purposes of on-the-scene investigation is a more limited
    intrusion into a person’s liberty than an arrest. Cloman,
    254 Or at 8-9. In 1973, the Oregon legislature sought
    to codify the constitutional limitations that Cloman and
    8
    Although defendant contested Malek’s justification to effect the initial traffic
    stop at trial, he does not renew that argument on review.
    776	                                                          State v. Watson
    Terry had articulated. ORS 131.615.9 See State v. Valdez,
    
    7 Or 621
    , 624-26, 561 P2d 1006 (1977) (describing
    origin of stop statutes); see also Fair, 353 Or at 602-03 n 7
    (same).
    Those statutes are still in effect.10 ORS 131.615
    permits the police to stop a person based on “reasonable
    suspicion” of criminal activity and make a “reasonable
    inquiry.” ORS 131.615(3) provides that “[t]he inquiry shall be
    considered reasonable if it is limited to * * * [t]he immediate
    circumstances that aroused the officer’s suspicion” or
    to “[o]ther circumstances arising during the course of
    the detention and inquiry that give rise to a reasonable
    suspicion of criminal activity[.]” ORS 131.615(2) provides
    that “[t]he detention and inquiry shall be conducted in the
    vicinity of the stop and for no longer than a reasonable
    time.” ORS 810.410,11 which establishes police authority
    to conduct traffic stops, make arrests, and issue citations,
    includes similar provisions. ORS 810.410(3)(b) provides that
    9
    ORS 131.615 provides:
    “(1)  A peace officer who reasonably suspects that a person has committed
    or is about to commit a crime may stop the person and, after informing the
    person that the peace officer is a peace officer, make a reasonable inquiry.
    “(2) The detention and inquiry shall be conducted in the vicinity of the
    stop 	 and for no longer than a reasonable time.
    “(3)  The inquiry shall be considered reasonable if it is limited to:
    “(a)  The immediate circumstances that aroused the officer’s suspicion;
    “(b)  Other circumstances arising during the course of the detention and
    inquiry that give rise to a reasonable suspicion of criminal activity; and
    “(c)  Ensuring the safety of the officer, the person stopped or other persons
    present, including an inquiry regarding the presence of weapons.
    “(4) The inquiry may include a request for consent to search in relation
    to the circumstances specified in subsection (3) of this section or to search for
    items of evidence otherwise subject to search or seizure under ORS 133.535.
    “(5)  A peace officer making a stop may use the degree of force reasonably
    necessary to make the stop and ensure the safety of the peace officer, the
    person stopped or other persons who are present.”
    10
    Those statutes have been amended since their enactment, but not in ways
    that affect our analysis in this case.
    11
    ORS 810.410 provides, in part:
    “(3)  A police officer:
    “* * * * *
    “(b)  May stop and detain a person for a traffic violation for the purposes
    of investigation reasonably related to the traffic violation, identification and
    issuance of citation.
    Cite as 
    353 Or 768
     (2013)	777
    an officer may stop and detain a person “for the purposes
    of investigation reasonably related to the traffic violation,
    identification and issuance of citation.” Officers may
    take other unrelated actions only when they have safety
    concerns, ORS 810.410(3)(d), or develop additional suspicion
    of criminal activity, ORS 810.410(3)(c). Similarly, both ORS
    131.615(5) and ORS 810.410(3)(f) allow use of force only to
    the degree that is “reasonably necessary to make the stop
    and ensure the safety of the police officer, the person stopped
    or other persons present.” Thus, by statute, an officer’s
    authority to detain a person based on reasonable suspicion
    is limited to activities that are reasonably related to the
    investigation of the suspected violation and reasonably
    necessary to effectuate that investigation.
    Following the enactment of ORS 131.615 and ORS
    810.410, this court decided issues concerning police authority
    during the course of traffic stops on statutory grounds. See,
    e.g., State v. Toevs, 
    327 Or 525
    , 964 P2d 1007 (1998); State v.
    Dominguez-Martinez, 
    321 Or 206
    , 895 P2d 306 (1995); State
    v. Porter, 
    312 Or 112
    , 817 P2d 1306 (1991); State v. Farley,
    
    308 Or 91
    , 775 P2d 835 (1989). Because this court analyzes
    statutory issues before reaching constitutional ones, the court
    evaluated the officers’ actions in those cases to determine
    whether they had violated the applicable Oregon statutes
    and often did not explicitly address their constitutional
    dimensions. See Holmes, 
    311 Or at 404
     (“Before reaching
    defendant’s state and federal constitutional claims, we
    first examine whether the deputy sheriff acted lawfully
    under proper authorization by a politically accountable
    lawmaker.”). Then, in 1997, the legislature enacted ORS
    “(c)  May make an inquiry into circumstances arising during the course of
    a detention and investigation under paragraph (b) of this subsection that give
    rise to a reasonable suspicion of criminal activity.
    “(d)  May make an inquiry to ensure the safety of the officer, the person
    stopped or other persons present, including an inquiry regarding the presence
    of weapons.
    “(e) May request consent to search in relation to the circumstances
    referred to in paragraph (c) of this subsection or to search for items of evidence
    otherwise subject to search and seizure under ORS 133.535.
    “(f) May use the degree of force reasonably necessary to make the stop
    and ensure the safety of the police officer, the person stopped or other persons

    136.432, which provides that courts may not exclude evidence
    obtained in violation of any statutory provision unless
    exclusion is required by the federal or state constitutions
    or certain rules of evidence.12 See Rodgers/Kirkeby, 
    347 Or at 621
     (describing statute). Once that statute took effect,
    defendants who sought to exclude evidence obtained during
    traffic stops asserted constitutional arguments in support of
    their motions to suppress, and courts were required to reach
    those arguments.
    Since 1997, this court has decided two cases
    that address the limits that Article I, section 9, places
    on temporary seizures, or stops. The first of those cases
    was Rodgers/Kirkeby, in which the court held that,
    under Article I, section 9, as under ORS 810.410(3)(b),
    “[p]olice authority to detain a motorist dissipates when the
    investigation reasonably related to that traffic infraction,
    the identification of persons, and the issuance of a citation
    (if any) is completed or reasonably should be completed.”
    
    347 Or at 623
    . The court determined that police officers had
    violated the constitutional rights of the defendants because,
    after completing their investigation of the traffic violations
    at issue, the officers had continued to detain the defendants
    and had questioned them about unrelated criminal activity
    without reasonable suspicion that they had engaged in such
    activity. The court held that Article I, section 9, “permits the
    police to stop and briefly detain motorists for investigation
    of noncriminal traffic violations.” 
    Id. at 624
     (emphasis in
    original). Police conduct during a noncriminal traffic stop
    does not further implicate Article I, section 9, the court
    explained, “so long as the detention is limited and the police
    conduct is reasonably related to the investigation of the
    noncriminal traffic violation.” 
    Id.
     (emphasis added). Thus,
    under Rodgers/Kirkeby, it is the justification for the stop—
    12
    ORS 136.432 provides that
    “[a] court may not exclude relevant and otherwise admissible evidence
    in a criminal action on the grounds that it was obtained in violation of any
    statutory provision unless exclusion of the evidence is required by:
    “(1)  The United States Constitution or the Oregon Constitution;
    “(2) The rules of evidence governing privileges and the admission of
    hearsay; or
    “(3)  The rights of the press.”

    the probable cause to believe that a driver has committed
    a traffic infraction and the state’s interest in investigating
    that potential infraction—that delineates the lawful bounds
    of the traffic stop:
    “Police authority to perform a traffic stop arises out of
    the facts that created probable cause to believe that there
    has been unlawful, noncriminal activity, viz., a traffic
    infraction. Police authority to detain a motorist dissipates
    when the investigation reasonably related to that traffic
    infraction, the identification of persons, and the issuance
    of a citation (if any) is completed or reasonably should be
    completed. Other or further conduct by the police, beyond
    that reasonably related to the traffic violation, must be
    justified on some basis other than the traffic violation.”
    
    347 Or at 623
     (emphasis in original).13
    More recently, in Fair, this court addressed the
    constitutional limits on police authority to temporarily
    detain or stop a person in a different noncriminal context. In
    Fair, law enforcement officers temporarily seized a woman
    whom they reasonably believed was a material witness or
    a victim of a recent or ongoing assault. After paying “due
    regard” both to “the practical necessities of effective law
    enforcement” and to the liberty interests protected by the
    constitution, the court held that the stop and on-the-scene
    detention of a likely material witness will be constitutional
    if
    “(1) the officer reasonably believes that an offense involving
    danger of forcible injury to a person recently has been
    committed nearby; (2) the officer reasonably believes that
    the person has knowledge that may aid the investigation
    of the suspected crime; and (3) the detention is reasonably
    necessary to obtain or verify the identity of the person, or to
    obtain an account of the crime.”
    Fair, 353 Or at 609. With that principle in mind, the court
    explained that the officers’ warrants check and their
    questions concerning the defendant’s arrest history did
    not “exceed the permissible scope of the stop,” because
    those actions were reasonably related to the purpose of
    13
    Whether that principle extends to inquiries during the course of a stop is a
    question that we do not address in this case. We also do not address the extent to
    which Rodgers/Kirkeby answers that question.
    780	                                             State v. Watson
    the detention. Id. at 614. Because the defendant lacked a
    driver’s license or other form of identification, the officers’
    check for outstanding warrants was reasonably related to
    the purpose of determining the defendant’s identity. When
    dispatch reported only that it had had “some form of contact”
    with a person with the defendant’s maiden name, the
    officers’ subsequent questions concerning the defendant’s
    arrest history were reasonably related to their investigation
    of the crime of assault; specifically, the questions assisted
    the officers in ascertaining that the defendant did not have
    a prior history of domestic violence, thereby providing
    support for the officers’ decision to arrest the defendant’s
    husband as the assailant. Id. at 614.
    Similar principles also are evident in this court’s
    discussion of the limitations that Article I, section 9,
    imposes on officers’ authority to search persons whom they
    have seized. For instance, in State v. Owens, 
    302 Or 196
    , 202,
    729 P2d 524 (1986), this court held that Article I, section
    9, permits officers to search without a warrant when the
    search is incident to arrest, but limits such searches to those
    related to the arrest “in time, space and intensity.” The court
    explained that,
    “[u]nder the Oregon Constitution, a search incident to
    arrest is valid when it relates to a crime which there is
    probable cause to believe the arrestee has committed, and
    when it is reasonable in all the circumstances. *  * This
    *
    probable cause requirement properly limits the objects to
    be sought in searches incident to arrest, and thus limits the
    intensity of the search.”
    
    Id.
     at 204 (citing State v. Caraher, 
    293 Or 741
    , 653 P2d 942
    (1982)).
    An officer’s authority to search in the interest of
    officer safety is similarly constrained. When an officer
    develops a reasonable suspicion that a person may pose an
    immediate threat of serious physical injury to the officer or
    to others then present, the officer may search that person
    without a warrant without violating Article I, section 9. See
    State v. Bates, 
    304 Or 519
    , 524, 747 P2d 991 (1987). How-
    ever, the scope of the search is limited to its constitutionally
    permitted purpose and must be reasonably necessary to
    Cite as 
    353 Or 768
     (2013)	781
    effectuate that purpose. See State v. Rudder, 
    347 Or 14
    ,
    23, 217 P3d 1064 (2009) (explaining that the protective
    measures that police officers take must be “proportionate” to
    any threat that the officers reasonably perceive). In Rudder,
    an officer who had reasonable suspicion to believe that the
    defendant might be armed and dangerous attempted to
    conduct a patdown and opened and inspected the contents
    of the defendant’s pocket. The court explained that the
    patdown “was the type of limited search that this court
    generally has approved when officer safety concerns arise
    in the course of a lawful police stop” because, although a
    patdown constitutes an intrusion into the privacy interests
    of an individual, the intrusion is limited to what is reason-
    ably necessary to “identify those objects that are relevant
    to * * * safety concerns.” 
    Id. at 24
    . A “more intrusive” search
    would require “something more[,] * * * either probable cause
    or some greater justification than was present here.” 
    Id. at 25
    .
    Thus, both Oregon statutes and this court’s Article
    I, section 9, case law require that law enforcement officers
    have a justification for temporarily seizing or stopping a
    person to conduct an investigation, and that the officer’s
    activities be reasonably related to that investigation and
    reasonably necessary to effectuate it. If the officer’s activities
    exceed those limits, then there must be an independent
    constitutional justification for those activities.
    In applying the above principles to the facts of this
    case, we first note that Malek was constitutionally justified
    in stopping defendant. Malek had probable cause to believe
    that defendant had committed a noncriminal traffic infrac-
    tion; therefore, Article I, section 9, permitted Malek to stop
    defendant and to investigate whether defendant had in fact
    committed that infraction. Defendant does not disagree. He
    contends, however, that not all of Malek’s activities were
    reasonably related to that investigation. Defendant argues
    that, because Malek decided not to issue defendant a citation
    and did not doubt defendant’s identity as it appeared on
    the face of defendant’s driver’s license, Malek exceeded the
    limits of Article I, section 9, by detaining defendant for 10
    minutes to conduct records and warrants checks and an
    782	                                                            State v. Watson
    unrelated criminal investigation pertaining to defendant’s
    drug use.
    We take each of the actions that defendant
    challenges in turn, beginning with the records check. As
    defendant recognizes, an officer’s determination of a person’s
    identity generally is reasonably related to the officer’s
    investigation of a traffic infraction. Contrary to defendant’s
    position, however, verification of a person’s identity and the
    issuance of a citation are not the only activities that may
    be reasonably related to the investigation. An officer who
    stops a driver also may release the driver, and a reasonable
    investigation may therefore include a determination of
    whether the driver has valid driving privileges, as required
    by ORS 807.010.14 As the Court of Appeals has noted, “When
    police officers detain a person on probable cause of violating
    a traffic law, it is reasonable to determine whether the
    person is licensed to continue on his or her way after the
    encounter ends.” State v. Hall, 
    238 Or App 75
    , 79, 241 P3d
    757 (2010).15 Because Malek conducted the records check
    with the purpose of verifying defendant’s driving privileges,
    Malek’s detention of defendant to conduct that check did
    not violate Article I, section 9, unless the detention was
    unreasonably lengthy. See Rodgers/Kirkeby, 347 Or at 623
    (“Police authority to detain a motorist dissipates when the
    14
    ORS 807.010 provides, in part:
    “(1)  A person commits the offense of operating a vehicle without driving
    privileges if the person operates a motor vehicle upon a highway or premises
    open to the public in this state and the person does not have an appropriate
    grant of driving privileges from this state in the form of a license, driver
    permit, endorsement or statutory grant of driving privileges allowing the
    person to engage in the particular type of operation.
    “* * * * *
    “(4) Except as provided in subsection (5) of this section, the offense
    described in subsection (1) of this section, operating a vehicle without driving
    privileges, is a Class B traffic violation.”
    15
    Police authority to verify records incident to “routine traffic stops” has been
    consistently approved and upheld by both federal and state courts. See, e.g., United
    States v. Shabazz, 993 F2d 431, 437 (5th Cir 1993) (“[W]e have no doubt, that in a
    valid traffic stop, an officer can request a driver’s license, insurance papers, vehicle
    registration, run a computer check thereon * * *.”); United States v. Digiovanni, 650
    F3d 498, 507 (4th Cir 2011); United States v. Villa, 589 F3d 1334, 1339 (10th Cir
    2009); State v. Lee, 263 Neb 663, 
    658 NW 2d 669
    , 676 (2003); Fender v. State, 
    2003 WY 96
    , 74 P3d 1220, 1225 (Wyo 2003).

    completed.”) (emphasis added).16
    Malek testified that his records and warrants checks
    generally take between four and 10 minutes and that, in this
    case, the checks took approximately 10 minutes. Although
    defendant contends that verifying driving privileges can
    take much longer than simply determining whether a license
    is facially valid, we have concluded that Malek was entitled
    to verify defendant’s driving privileges, and defendant
    does not contend that 10 minutes was an unreasonably
    long period of time given the particular circumstances
    presented.17 We therefore conclude that Malek’s detention of
    defendant to conduct the records check was not unreason-
    ably lengthy.
    Malek’s warrants check necessitates a different
    analysis. In Fair, this court upheld a warrants check of a
    material witness, because the officers were unable to confirm
    her identity by means of a license check and because knowing
    whether she had a prior history of domestic violence would
    advance the officers’ investigation of the crime at issue. Fair,
    353 Or at 614. In this case, Malek did not testify that the
    warrants check was similarly related to the investigation
    of the traffic infraction for which he stopped defendant.
    Malek asked dispatch to conduct a warrants check because
    that was his routine practice. Whether a warrants check
    is reasonably related to the investigation or otherwise
    constitutionally justified, for instance, to protect officer
    16
    The United States Supreme Court has similarly interpreted the Fourth
    Amendment, holding that an investigative detention must be temporary and last
    no longer than is necessary to effectuate the purpose of the stop. Florida v. Royer,
    
    460 US 491
    , 500, 
    103 S Ct 1319
    , 
    75 L Ed 2d 229
     (1983). In assessing the length of
    the detention, the Court takes into account whether the police diligently pursued
    their investigation. United States v. Place, 
    462 US 696
    , 709, 
    103 S Ct 2637
    , 
    77 L Ed 110
     (1983). No rigid time limitation is imposed; rather, courts must consider the
    law enforcement purposes to be served by the stop as well as the time reasonably
    needed to effectuate those purposes, and “common sense and ordinary human
    experience must govern over rigid criteria.” United States v. Sharpe, 
    470 US 675
    ,
    685, 
    105 S Ct 1568
    , 
    84 L Ed 2d 605
     (1985). The question, as always, is whether the
    police acted reasonably under the circumstances.

    784	                                                       State v. Watson
    safety, presents an important question, but one that we
    need not decide here.
    Incriminating evidence will be suppressed only
    if the evidence was “a product of” an unconstitutional
    act. State v. Juarez-Godinez, 
    326 Or 1
    , 9, 942 P2d 772
    (1997). In this case, the warrants check did not lead to the
    discovery of the evidence that defendant sought to suppress.
    The warrants check came back clean, and although
    incriminating evidence was discovered during the time
    that it took to conduct the warrants check, Malek’s records
    check, which was reasonably related to the investigation,
    took the same amount of time. Malek requested the records
    and warrants checks simultaneously and received the
    results of those checks from dispatch simultaneously; the
    record does not demonstrate that it took Malek longer to
    conduct the warrants check than it would have taken to
    conduct the records check alone. There is no indication that
    the warrants check produced incriminating evidence or
    extended the duration of the stop beyond the time that was
    reasonably necessary to conduct the records check; thus,
    even if the warrants check was not reasonably related to
    the investigation, it was not a basis for suppression of the
    incriminating evidence that the police discovered.
    Finally, we consider defendant’s challenges to
    Malek’s questioning of defendant concerning rumors of his
    involvement with drugs, Malek’s requests for consent to
    search, and Malek’s request that defendant exit his car. When
    we consider those acts in context, we find it unnecessary to
    determine whether they exceeded the constitutional scope
    of the stop.18 Like the warrants check, those actions did not
    lead to the discovery of the evidence that defendant sought
    to suppress. Defendant denied selling drugs and denied
    Malek’s request to search. Malek did not detect the odor
    of marijuana as a result of his request that defendant step
    out of his car; rather, it was Deputy Ruble’s detection of the
    odor of marijuana coming from defendant’s car, an act that
    defendant does not challenge, that launched the chain of
    events that resulted in defendant’s arrest. After Ruble told
    18
    In this case, we do not address whether an officer’s inquiries made during
    the pendency of a valid seizure implicate Article I, section 9.
    Cite as 
    353 Or 768
     (2013)	785
    Malek that he smelled marijuana, Malek had the requisite
    reasonable suspicion of criminal activity that permitted him
    to investigate further. On investigation, Malek corroborated
    the odor and obtained defendant’s admission that he was
    in possession of marijuana, as well as the drug-detection
    dog’s confirmation that there were drugs in defendant’s car.
    Malek then had probable cause to believe that he would find
    marijuana in the car and was constitutionally permitted to
    search it.19 It was the series of acts that began with Ruble’s
    detection of the odor of marijuana, and not Malek’s earlier
    actions, that led to the discovery of evidence.
    As we have explained, an officer may develop
    reasonable suspicion or probable cause during the course
    of a traffic stop that may justify activities that would not
    have been permissible based on the original purpose of the
    stop. That is exactly what occurred here. Malek developed
    reasonable suspicion that defendant had marijuana in his
    car, and that reasonable suspicion justified Malek’s further
    investigation. Malek’s confirmation of the odor, further
    questioning of defendant, and use of the drug-detection
    dog were reasonably related to that investigation and gave
    Malek probable cause to search defendant’s car.
    We conclude that the trial court did not err in
    denying defendant’s motion to suppress. Malek’s activities
    either were reasonably related to the investigation of the
    traffic infraction, did not lead to the discovery of the evidence
    that defendant sought to suppress, or were justified by the
    reasonable suspicion of criminal activity and probable cause
    that Malek developed during the course of the stop.
    19
    Defendant challenged Malek’s probable cause to search at trial. He did not
    advance that argument on appeal. At the time that Malek searched defendant’s
    vehicle, two officers had smelled marijuana, defendant had admitted that there
    was marijuana in the car, and a drug detection dog had indicated that there were
    drugs in the car. Pursuant to the “automobile exception,” an officer who has stopped
    a mobile vehicle may conduct a search without a warrant if the officer has probable
    cause to believe that the vehicle contains evidence of a crime. See State v. Brown,
    
    301 Or 268
    , 274, 721 P2d 1357 (1986) (describing exception). We accept the trial
    court judge’s implicit finding that Malek had probable cause to conduct the search
    as supported by the evidence in the record: The smell, admission, and drug-dog
    detection were sufficient to create the requisite probable cause of criminal activity.
    See State v. Foster, 
    350 Or 161
    , 170, 252 P3d 292 (2011) (alert by properly trained
    and reliable drug-detection dog can provide probable cause for search).
