    DAVIS, Judge.
    Jereme D. Lukoskie (“Defendant”) appeals from a judgment
    convicting him of driving while impaired (“DWI”).                  On appeal, he
    contends that the trial court erroneously (1) denied his pre-
    trial motion to suppress all evidence                 obtained     while he was
    stopped    at   a   checkpoint;     and   (2)    refused    to   allow    him   the
    opportunity to make an offer of proof at trial.                    After careful
    -2-
    review, we affirm the trial court’s denial of Defendant’s motion
    to    suppress    and    hold    that          the    trial      court   did     not    commit
    prejudicial error in limiting his ability to make an offer of
    proof.
    Factual Background
    The State presented evidence at trial tending to establish
    the    following       facts:    On       26     February        2010,    the    Charlotte-
    Mecklenburg Police Department (“CMPD”) established an impaired
    driving checkpoint at the 6000 block of Brookshire Boulevard
    supervised by Sergeant David Sloan (“Sergeant Sloan”).                                 Officer
    Matthew Pressley (“Officer Pressley”) manned the outbound lanes
    of Brookshire Boulevard where he observed Defendant enter the
    checkpoint driving a Volkswagen Passat sedan.                            Officer Pressley
    approached       the    vehicle       and        engaged         in   conversation           with
    Defendant, informing Defendant that he was at a DWI checkpoint.
    Officer Pressley asked Defendant “how much, if anything, he had
    to    drink.”    Defendant      responded            that   he    had    consumed      “a     few
    drinks two hours earlier.”
    Officer     Pressley      then       directed          Defendant     to     exit       the
    vehicle and perform a series of field sobriety tests.                              Defendant
    failed    to     perform   any       of    the       tests       to   Officer    Pressley’s
    satisfaction.          Based    on    Defendant’s           slurred      speech,       red   and
    -3-
    glassy eyes, the odor of alcohol on his breath, and Defendant’s
    poor performance on the field sobriety tests, Officer Pressley
    formed the opinion that Defendant was appreciably impaired by
    the consumption of alcohol.
    Defendant was placed under arrest for impaired driving and
    taken to a nearby blood alcohol testing mobile unit for a breath
    test.    Defendant registered a .16 blood alcohol concentration
    level.     Defendant was then charged with driving while impaired
    in violation of 
    N.C. Gen. Stat. § 20-138.1
    .
    On 13 July 2010, a trial was held in Mecklenburg County
    District Court.     Defendant was convicted of DWI and placed on
    unsupervised   probation   for    one    year.      Defendant   appealed    to
    superior court.
    On 6 October 2010, Defendant filed a motion to suppress all
    evidence    resulting   from     the     checkpoint,    arguing   that     the
    checkpoint failed to meet constitutional standards.               The motion
    was denied.
    A jury trial was held beginning on 19 September 2012.                  The
    jury found Defendant guilty of DWI.              The trial court sentenced
    Defendant to 30 days imprisonment but suspended the sentence and
    placed him on unsupervised probation for 12 months.                Defendant
    gave timely notice of appeal.

    Analysis
    I. Denial of Motion To Suppress
    The bulk of Defendant’s appeal arises from his argument
    that the trial court erred in denying his motion to suppress.
    We conclude that his argument lacks merit.
    Our   review      of    a   trial    court's     ruling    on   a    motion    to
    suppress is “strictly limited to determining whether the trial
    judge's underlying findings of fact are supported by competent
    evidence,      in      which   event      they    are   conclusively       binding    on
    appeal, and whether those factual findings in turn support the
    judge's ultimate conclusions of law.”                   State v. Cooke, 
    306 N.C. 132
    ,    134,     
    291 S.E.2d 618
    ,     619    (1982).       Additionally,       any
    findings of fact that are not specifically challenged by a party
    are    “deemed      to   be    supported     by    competent     evidence     and    are
    binding on appeal.”            State v. Roberson, 
    163 N.C. App. 129
    , 132,
    
    592 S.E.2d 733
    , 735–36 (2004).                    “The conclusions of law made
    from the findings of fact are reviewable de novo.”                           State v.
    Brown, 
    199 N.C. App. 253
    , 256, 
    681 S.E.2d 460
    , 463 (2009).
    A. Sufficiency of Findings of Fact
    The   trial       court     made    the    following    pertinent      findings
    pursuant to Defendant’s pre-trial motion to suppress evidence
    arising from the DWI checkpoint:
    -5-
    1.   From 11:00 pm Friday February 27th 2010
    to 3:00 am Saturday February 28th, 2010 the
    Charlotte-Mecklenburg    Police   Department
    operated   a   DWI    Checking  Station   on
    Brookshire Blvd., a public street in the
    area.
    2.   The Checking Station was operated in
    accordance with a written plan (State's
    Exhibit #1) drafted by Sergeant David Sloan
    pursuant to, and in accordance with N.C.G.S.
    20-16A. Sergeant Sloan briefed the officers
    working the checkpoint that night as to how
    to   conduct   the    Checking  Station   in
    accordance with the plan.
    3.    The plan provided for the location and
    time of the checkpoint. Sergeant Sloan has
    been supervising DWI checking stations for
    several years. He has been working major
    traffic units for two decades. Sergeant
    Sloan    personally  had  made  several  DWI
    arrests in the area near Brookshire Blvd.
    Sergeant Sloan testified that the location
    of the checkpoint location was chosen based
    on traffic fatalities, prior DWI arrest
    within the area, and the presence of several
    bars in the area.
    4.   The purpose of the checkpoint was to
    deter driving while impaired and related
    accidents through DWI detection and arrest.
    The area chosen is used twice a year by CMPD
    for checkpoint operations, either on Freedom
    Dr. or Brookshire Blvd. The checkpoints have
    yielded prior DWI arrest[s].
    5.   The   strategic plan   set    forth  the
    appropriate notifications to      the public
    including signs and markers and   patrol cars
    with lights activated notifying    the public
    of the checkpoint.
    6.   The plan provided for each car to be
    -6-
    stopped and for officers to ask for a
    driver's   license   and  to   check   their
    registration and to engage in conversation.
    If there were no issues with the license and
    no evidence of alcohol or drug consumption
    was present, motorists would be free to
    leave. Such a stop took 10-30 seconds. If
    alcohol was detected, the drivers were asked
    to step out of their vehicles and perform
    field sobriety tests.
    7.   Sergeant     Sloan      briefed     all
    participating law enforcement officers of
    the specific instructions to which each
    officer was to adhere fifteen minutes before
    the checkpoint began. Sergeant Sloan was the
    only officer allowed to deviate from the
    plan. The plan did not cause a back up in
    traffic. Sergeant Sloan never had to deviate
    from the plan.
    8.   The Checking Station was      administered
    in accordance with the plan.
    9.   The   defendant    was   stopped   at   the
    Checking Station.
    10. The defendant admitted several reports
    of arrest in the area of the checkpoint that
    did not indicate a large number of DWI
    arrest[s]; however, the [sic] Sergeant Sloan
    testified    that  the    reports   do   not
    necessarily show the number of DWI arrest[s]
    in the area.
    11. The reports were based on calls for
    service   and   incidents    in   the  area;
    therefore, a DWI arrest may not be listed in
    the reports produced by the defense.
    12. Area where the checkpoint was set up is
    a high traffic area. The purpose of the
    checkpoint was to detect DWI individuals and
    the checkpoint was not set up as a means for
    -7-
    stopping the public for some other purpose.
    Based on its findings of fact, the trial court made the
    following conclusion of law:
    1.   The Court concludes that, the        Checking
    Station was operated in accordance       with the
    United    States    and     North         Carolina
    Constitutions and North Carolina         law, and
    does not violate the 4th Amendment.
    With    regard   to   the   trial    court’s    findings    of     fact,
    Defendant only challenges findings 2, 3, 4, 10, 11, and 12.
    Thus, findings 1 and 5-9 are binding on appeal.             Roberson, 163
    N.C. App. at 132, 
    592 S.E.2d at 735-36
    .
    Findings 2-4 address (1) the degree to which the checkpoint
    was   operated    in   accordance   with    a   written   plan;    (2)     the
    rationale for the checkpoint location; and (3) the checkpoint’s
    purpose.     Defendant argues that these findings are not supported
    by competent evidence in that the checkpoint “lacked a lawful
    primary programmatic purpose.”
    We believe that findings 2-4 are supported by the testimony
    of both Officer Pressley and Sergeant Sloan, which adequately
    explained the purpose of the checkpoint and the manner in which
    it    was    implemented.     Sergeant     Sloan     testified    that    the
    checkpoint occurred because “we have [had] numerous DWI arrests
    and fatalities that have occurred on Brookshire Boulevard.”                The
    -8-
    written plan for the checkpoint — State’s Exhibit No. 1 — also
    stated that it was a “sobriety checking station” and that its
    purpose   was   to    check      for    impaired    driving.       Sergeant    Sloan
    testified that “approximately 15 minutes prior to the check-in
    station beginning we had a briefing . . . [to] make sure every
    officer is briefed on the plan and . . . [to] make sure they
    follow the procedures set forth in the plan.”                        Therefore, we
    conclude that findings of fact 2-4 are supported by competent
    evidence.
    Defendant next challenges findings 10 and 11, both of which
    address reports Defendant introduced into evidence outlining the
    number of accidents previously occurring in the vicinity of the
    checkpoint     area   and   the    relatively       few    DWI-related   incidents
    listed therein.
    At the suppression hearing, Sergeant Sloan testified that
    the   report    offered     by    the    Defendant    would    not    specifically
    reflect     DWI-related     offenses       unless    the    call   reporting    the
    incident referred to it as being DWI-related:                      “The call for
    service comes in as a crash, the officer gets out, investigates
    it, and makes a DWI arrest based on that wreck, but it won't be
    generated as a DWI offense. It's generated                     as an accident.”
    -9-
    Thus, Sergeant Sloan’s testimony served as competent evidence to
    support findings 10 and 11.
    Finally, Defendant asserts that finding 12 - which states,
    in pertinent part, “that the purpose of the checkpoint was to
    detect DWI individuals and the checkpoint was not set up as a
    means for stopping the public for some other purpose” - was not
    supported by competent evidence.                     He contends that the State
    bore    the     burden       of   demonstrating        that      the   checkpoint     was
    “undertaken for a lawful primary programmatic purpose” and the
    State   failed       to    meet    its      burden    by    relying    solely    on   the
    testimony of Officer Pressley and Sergeant Sloan.
    At     trial,      the     State     offered    as     an    exhibit     the    DWI
    checkpoint plan.          Sergeant Sloan testified that this plan, which
    was followed by every officer participating in the checkpoint,
    clearly states that the programmatic purpose of the checking
    station was to check for sobriety.                    The plan expressly provides
    that “the sobriety checkpoint . . .                        will apprehend impaired
    drivers”      and    also       contains     a    number    of     factors    that    were
    considered      by     the      CMPD   in   determining       whether    the    checking
    station would be successful.                     Those factors included: (1) the
    number of accidents in the area involving impaired drivers; (2)
    the number of bars and drinking establishments in the area; (3)
    -10-
    the number of DWI arrests made in the area; (4) the number of
    DWI arrests made on Friday nights; and (5) the number of DWI
    arrests made during these specific hours of the night.                                This
    Court has held that the State is permitted to establish the
    purpose of a checkpoint through the testimony of a participating
    officer.      State v. Burroughs, 
    185 N.C. App. 496
    , 499-500, 
    648 S.E.2d 561
    , 565-66 (2007) (“Our Court has previously held that
    where   there      is    no   evidence      in    the   record    to     contradict      the
    State's proffered purpose for a checkpoint, a trial court may
    rely    on    the       testifying      police      officer's         assertion     of    a
    legitimate      primary       purpose.”)           Based   on     the     testimony       of
    Sergeant     Sloan      and   Officer    Pressley        and    the    checkpoint     plan
    itself, we conclude that the State presented competent evidence
    to support the trial court’s finding that the sole purpose of
    the    checkpoint       was   to     detect      persons   who    are    driving     while
    impaired.
    B. Constitutionality of Checkpoint
    Having established that findings of fact 2, 3, 4, 10, 11,
    and 12 were supported by competent evidence, we next determine
    whether      the     trial     court’s        findings     of     fact     support       its
    conclusion      of      law   that    the     checkpoint        was    operated    within
    constitutional boundaries. The United States Supreme Court has
    -11-
    held that an impaired driving checkpoint is constitutional if
    vehicles    are     stopped    according       to   a   neutral,      articulable
    standard.     Michigan Dept. of State Police v. Sitz, 
    496 U.S. 444
    ,
    
    110 L.Ed.2d 412
     (1990).         
    N.C. Gen. Stat. § 20-16
    .3A governs the
    establishment, organization, and management of impaired driving
    checkpoints    in   North     Carolina   and    sets    forth   the    bases   for
    stopping vehicles at such checkpoints.
    A   law-enforcement    agency may   conduct
    checking stations to determine compliance
    with the provisions of this Chapter. If the
    agency is conducting a checking station for
    the purposes of determining compliance with
    this Chapter, it must:
    . . .
    (2) Designate in advance the pattern both
    for stopping vehicles and for requesting
    drivers that are stopped to produce drivers
    license,     registration,  or    insurance
    information.
    (2a) Operate under a written policy that
    provides guidelines for the pattern, which
    need not be in writing. The policy may be
    either the agency's own policy, or if the
    agency does not have a written policy, it
    may be the policy of another law enforcement
    agency,   and     may    include    contingency
    provisions for altering either pattern if
    actual traffic conditions are different from
    those anticipated, but no individual officer
    may be given discretion as to which vehicle
    is stopped or, of the vehicles stopped,
    which driver is requested to produce drivers
    license,     registration,     or     insurance
    information.    If    officers    of    a   law
    -12-
    enforcement  agency  are   operating under
    another agency's policy, it must be stated
    in writing.
    (3) Advise the public that an authorized
    checking   station   is   being  operated   by
    having, at a minimum, one law enforcement
    vehicle with its blue light in operation
    during   the   conducting   of  the   checking
    station.
    
    N.C. Gen. Stat. § 20-16
    .3A (2011).
    “[P]olice officers effectuate a seizure when they stop a
    vehicle at a checkpoint.          As with all seizures, checkpoints
    conform with the Fourth Amendment only if they are reasonable.”
    State v. Jarett, 
    203 N.C. App. 675
    , 677, 
    692 S.E.2d 420
    , 423
    (2010) (internal citations and quotation marks omitted).
    When   considering    a    challenge    to    a
    checkpoint,   the   reviewing     court    must
    undertake a two-part inquiry to determine
    whether the checkpoint meets constitutional
    requirements.   First,    the    court     must
    determine the primary programmatic purpose
    of the checkpoint . . . . Second, if a court
    finds that police had a legitimate primary
    programmatic   purpose   for    conducting    a
    checkpoint . . . [the court] must judge its
    reasonableness,           hence,            its
    constitutionality, on the basis of the
    individual circumstances.
    
    Id.
     (internal citations and quotation marks omitted).
    1. Primary Programmatic Purpose
    Defendant    argues     the   trial    court      erred   by   “finding   a
    legitimate   programmatic    purpose      for   the   checkpoint    where   the
    -13-
    only evidence regarding this purpose consisted of two police
    officers’ uncorroborated memories of incidents occurring in the
    area,” instead of “reports, data, or empirical information.”
    We reject Defendant’s argument on this issue because, as
    discussed above, competent evidence supported the trial court’s
    finding that the checkpoint was conducted for the legitimate
    purpose of apprehending impaired drivers.                See Burroughs, 185
    N.C. App. at 498-503, 
    648 S.E.2d at 562-66
     (holding that where
    defendant    failed    to    offer   evidence    that    stated   purpose   of
    vehicle   checkpoint    was    façade   for     separate,    unconstitutional
    purpose, trial court erred in excluding evidence obtained during
    checkpoint).
    In    reviewing    the    constitutionality     of   a   checkpoint,    the
    trial court is required, as an initial matter, to “‘examine the
    available evidence to determine the purpose of the checkpoint
    program.’”     State v. Gabriel, 
    192 N.C. App. 517
    , 521, 
    665 S.E.2d 581
    , 585 (2008) (quoting State v. Rose, 
    170 N.C. App. 284
    , 289,
    
    612 S.E.2d 336
    , 339, appeal dismissed and disc. review denied,
    
    359 N.C. 641
    , 
    617 S.E.2d 656
     (2005)).
    Our Court has previously held that where
    there is no evidence in the record to
    contradict the State's proffered purpose for
    a checkpoint, a trial court may rely on the
    testifying police officer's assertion of a
    legitimate primary purpose. However, where
    -14-
    there is evidence in the record that could
    support a finding of either a lawful or
    unlawful purpose, a trial court cannot rely
    solely on an officer's bare statements as to
    a checkpoint's purpose. In such cases, the
    trial court may not simply accept the
    State's invocation of a proper purpose, but
    instead must carr[y] out a close review of
    the scheme at issue. This type of searching
    inquiry is necessary to ensure that an
    illegal multi-purpose checkpoint [is not]
    made legal by the simple device of assigning
    the primary purpose to one objective instead
    of the other[.]
    State v. Veazey, 
    191 N.C. App. 181
    , 187, 
    662 S.E.2d 683
    , 687-88
    (2008)    (internal      citations      and     quotation     marks      omitted).
    “[W]hen   a    trooper's     testimony    varies      concerning    the   primary
    purpose of the checkpoint, the trial court is required to make
    findings regarding the actual primary purpose of the checkpoint
    and . . . to reach a conclusion regarding whether this purpose
    was lawful.”        Gabriel, 192 N.C. App. at 521, 
    665 S.E.2d at 585
    (internal citation and quotation marks omitted).
    Here,      as    shown   above,    Officer       Pressley’s    and    Sergeant
    Sloan’s testimony regarding the actual primary purpose of the
    checkpoint were consistent.            Both officers testified that the
    checkpoint’s     primary     purpose     was   for    DWI   detection.       Their
    testimony was further corroborated by the actual DWI checkpoint
    plan — drafted pursuant to 
    N.C. Gen. Stat. § 20-16
    .3A — which
    clearly   states     that    the   checkpoint    was    a   “sobriety     checking
    -15-
    station.”           Because   there     is    no     evidence      in    the    record      to
    contradict         the    State’s     proffered        purpose     for    the     checking
    station, we are satisfied that sufficient evidence existed to
    demonstrate          a    legitimate         programmatic         purpose        for        the
    checkpoint.         See Veazey, 191 N.C. App. at 187, 
    662 S.E.2d at 687
    (“[W]here there is no evidence in the record to contradict the
    State's proffered purpose for a checkpoint, a trial court may
    rely    on    the        testifying     police       officer's         assertion       of    a
    legitimate primary purpose.”).
    While Defendant attempts to rely on State v. Rose, 
    170 N.C. App. 284
    , 
    612 S.E.2d 336
     (2005), in support of his contention
    that the checkpoint lacked a valid programmatic purpose, his
    reliance      is     misplaced.         In     Rose,      the    trial    court        simply
    accepted,     without       comment,    the     field      officers'      label    of       the
    checkpoint as a license and registration checkpoint.                            This Court
    held that a trial court could not avoid the task of determining
    the    primary      programmatic       purpose       of   a     checkpoint      simply       by
    finding      that    a    checkpoint    had     at     least     one    lawful    purpose.
    Rose, 170 N.C. App. at 290, 
    612 S.E.2d at 340
    .                                 We further
    concluded that the trial court                  had failed to make necessary
    findings as to whether the checkpoint was appropriately tailored
    to meet a primary programmatic purpose.                       Id. at 293, 612 S.E.2d
    -16-
    at    341.      For    these      reasons,      we     reversed      the    defendant’s
    convictions and remanded for further findings of fact addressing
    whether the primary programmatic purpose was constitutionally
    permissible.      Id. at 293, 
    612 S.E.2d at 337
    .
    Defendant argues that Rose is analogous to the present case
    in    that    Sergeant    Sloan    did   not     take    any    reports,      data,   or
    empirical information into account when creating the plan for
    the checkpoint.          Defendant claims that this case is, therefore,
    no    different    than    Rose,    in   which        there    was   no    evidence   of
    purpose      offered   other    than     that    of    the    “individual      officers
    acting at the scene.”          Id. at 290, 
    612 S.E.2d at 340
    .
    However, in Rose, the court was faced with the issue of
    “spontaneous”      checkpoints         that     were    not     prescribed      by    any
    written plan or at the direction of any authority other than the
    officers that decided to conduct the stop.                           Id. at 294, 
    612 S.E.2d at 342
    .           Here, conversely, the checkpoint at issue was
    not   spontaneous      and   was    instead      governed       by   a     written   plan
    drafted by Sergeant Sloan pursuant to 
    N.C. Gen. Stat. § 20
    -
    16.3A.       Both Sergeant Sloan and Officer Pressley testified that
    the primary purpose of the checkpoint was to check for impaired
    drivers and that          the location was chosen because of                    traffic
    fatalities and prior DWI arrests within the area as well as the
    -17-
    existence of surrounding bars.                Furthermore, nothing in 
    N.C. Gen. Stat. § 20-16
    .3A requires officers to rely on empirical
    data in deciding where to establish a checkpoint.
    2. Reasonableness of Checkpoint
    Defendant     also        contends     that    the   trial    court     made
    insufficient      findings       regarding     the    reasonableness    of     the
    checkpoint.       Once   a trial court determines            that   the primary
    programmatic purpose of a checkpoint is proper, it must then
    apply the three-prong inquiry set forth by the United States
    Supreme Court in Brown v. Texas, 
    443 U.S. 47
    , 
    61 L.Ed.2d 357
    (1979),     in   order     to    determine     whether     the   checkpoint     is
    reasonable.      Jarrett, 203 N.C. App. at 679, 
    692 S.E.2d at
    424-
    25.   “Under Brown, the trial court must consider [1] the gravity
    of the public concerns served by the seizure[;][2] the degree to
    which the seizure advances the public interest[;] and [3] the
    severity of the interference with individual liberty.”                      Id. at
    679, 
    692 S.E.2d at 425
     (internal citations and quotation marks
    omitted).
    The first factor under Brown “analyzes the importance of
    the purpose of the checkpoint.                This factor is addressed by
    first identifying the primary programmatic purpose . . . and
    then assessing the importance of the particular                     stop to the
    -18-
    public.”        Rose,     170       N.C.    App.    at    294,    
    612 S.E.2d at 342
    (internal citation omitted).
    Both the United States Supreme Court and the Supreme Court
    of North Carolina have determined that the desire to eliminate
    impaired   driving       is     a    matter    of       substantial     public     concern.
    Sitz, 
    496 U.S. at 455
    , 
    110 L.Ed.2d at 423
     (“No one can seriously
    dispute the magnitude of the                   drunken driving problem or the
    States’ interest in eradicating it.”); see State v. Foreman, 
    351 N.C. 627
    ,     633,    
    527 S.E.2d 921
    ,    924-25       (2000)    (“Our    state’s
    interest in combating intoxicated drivers outweighs the minimal
    intrusion that an investigatory stop may impose upon a motorist
    under these circumstances.”).
    Under    the    second       prong     of    Brown,     the   trial    court      must
    determine “whether ‘[t]he police appropriately tailored their
    checkpoint stops’ to fit their primary purpose.”                             Veazey, 191
    N.C.   App.     at     191,   
    662 S.E.2d at 690
       (quoting      Illinois      v.
    Lidster, 
    540 U.S. 419
    , 427, 
    157 L.Ed.2d 843
    , 852 (2004)).
    Our Court has previously identified a number
    of non-exclusive factors that courts should
    consider   when    determining   whether    a
    checkpoint    is   appropriately    tailored,
    including:   whether   police   spontaneously
    decided to set up the checkpoint on a whim;
    whether police offered any reason why a
    particular road or stretch of road was
    chosen for the checkpoint; whether the
    checkpoint had a predetermined starting or
    -19-
    ending time; and whether police offered any
    reason why that particular time span was
    selected.
    Jarrett, 203 N.C. App. at 680, 
    692 S.E.2d at 425
    .
    Here, the checkpoint was not set up on a whim.                      Officer
    Sloan testified at the suppression hearing that the checkpoint
    plan    was   developed    a   week    prior    to   the   date    on    which    the
    checkpoint occurred.
    Sergeant Sloan also testified to the reason why the 6000
    block of Brookshire Boulevard was chosen.                  He stated that this
    checkpoint is chosen “at least twice a year at the same location
    due to the high number of DWI arrests and wrecks out at that
    location.”       Sergeant      Sloan   also    testified    that    each    time    a
    checkpoint has been established on Brookshire Boulevard, “we’ve
    netted more than double-digit DWI arrests.”
    Another   key   factor     under   the     second   prong    of    Brown    is
    ascertaining whether or not the checkpoint had a predetermined
    starting or ending time and whether any reason is offered about
    why that particular time span was selected.                 Here, the checking
    station plan had a predetermined starting time of 11:00 p.m. on
    26 February      2010 and an ending time of 3:00 a.m. on 27 February
    2010.   Furthermore,      Officer      Pressley   testified       that   this    time
    span was chosen
    -20-
    [du]e to high incidents of DWIs in and
    around   that   area    of   Brookshire, in
    particular on Friday nights . . . [t]he
    large number of drinking establishments in
    and around that area . . . [and] [t]he fact
    that that roadway is a major thoroughfare
    from downtown traffic and all the drinking
    establishments that are there.
    The third prong of Brown requires this Court to consider
    the   severity     of    the   interference    with    individual   liberty
    resulting from the checkpoint.         We have articulated a number of
    factors     that   are    relevant    in    making    this   consideration,
    including
    the checkpoint’s potential interference with
    legitimate traffic; whether police took
    steps to put drivers on notice of an
    approaching checkpoint; whether the location
    of   the   checkpoint   was    selected    by   a
    supervising    official,     rather    than    by
    officers   in   the   field;    whether   police
    stopped every vehicle that passed through
    the checkpoint, or stopped vehicles pursuant
    to a set pattern; whether drivers could see
    visible signs of the officers' authority;
    whether   police    operated    the   checkpoint
    pursuant to any oral or written guidelines;
    whether the officers were subject to any
    form   of   supervision;    and    whether    the
    officers received permission from their
    supervising    officer     to     conduct     the
    checkpoint[.]
    Jarrett, 203 N.C. App. at 681, 692 S.E.2d. at 425-26 (citation
    omitted).    While all of these factors are relevant, a trial
    -21-
    court does not need to explicitly address each one of them in
    its findings.         Id.
    Here,    Sergeant     Sloan   devised   the    checkpoint   plan,       which
    provided       the    written   guidelines     that   were   followed     at    the
    checkpoint, and personally supervised the checkpoint.                    The plan
    stated that          “CMPD finds that the stopping of every vehicle,
    tempered with the contingency of allowing vehicles through . . .
    only if traffic is congested by the checkpoint to an unforeseen
    and unreasonable level, is an acceptable and reasonable number
    of vehicles to stop.”            The plan also limited the officers to
    asking for the driver’s license of each driver and looking for
    signs of impairment.
    The trial court’s finding of fact 5 recognized that the
    plan   provided        for   appropriate   notifications      to   the    public,
    including “signs and markers” and “patrol cars with their lights
    activated.”          Officer Pressley testified that the checkpoint was
    marked by “large 4 foot x 4 foot orange neon [signs stating] DWI
    check-in station ahead” and that there was “at least one car in
    the roadway in each direction with blue lights activated and all
    of the officers in the roadway [were] wearing their traffic
    vests.”    Moreover, because every vehicle was to be stopped, the
    plan provided that “[i]f traffic conditions create a[n] . . .
    -22-
    unreasonable delay to the convenience of the motoring public,
    the supervising officer may temporarily allow vehicles through
    without being stopped.”
    The   trial    court’s     findings      —    along      with    the   competent
    evidence       supporting     these     findings         —    establish      that     any
    interference with the individual liberty of citizens affected by
    the checkpoint was no greater than necessary to achieve the
    important objectives at issue.                Therefore, the third prong of
    the Brown test was likewise satisfied.
    We conclude that the trial court’s findings of fact support
    its    legal     conclusion      that    the       checkpoint         comported      with
    constitutional standards.             Therefore, the trial court properly
    denied Defendant’s motion to suppress.
    II. Refusal To Allow Offer of Proof
    Defendant     also     argues     that       the   trial      court    erred     in
    refusing    to    allow    him   to   make    an    offer      of   proof    at   trial.
    Defendant sought to impeach the credibility of Officer Pressley
    by    questioning     him    about      the    basis         for    establishing      the
    checkpoint at this particular location on Brookshire Boulevard.
    The trial court stated that it would “not allow Defendant to
    supplement [his] motion to suppress,” but the court did agree to
    allow Defendant to question Officer Pressley on this subject for
    -23-
    the purpose of challenging his credibility.             Defendant’s counsel
    proceeded with this line of questioning.           However, after counsel
    was able to elicit several responses from Officer Pressley, the
    trial    court   refused   to   allow   any   further   questions   on   this
    issue.
    Q. Your testimony is that you know of a
    large amount of drinking establishments in
    this area. Can you name one of them –
    THE COURT: I'm going to stop you again.
    There
    has been no testimony in this trial about
    the number of drinking establishments. How
    does that go to his credibility? Tell the
    Court that.
    MR. SMITH: Your Honor, he testified -- I
    asked
    him the question why was the location
    picked. He said because of the number of
    drinking
    establishments in this location, the number
    of
    driving while impaired incidents and driving
    while impaired fatalities. That's exactly
    his testimony on the record. That was all in
    front of the jury.
    THE COURT: Sustained. I'm not going         to allow
    it. You can make the objection               for the
    record, and you can take it up              with the
    court of appeals. I'm not going to           allow it
    to be proffered. That's the Court's         ruling.
    MR. SMITH: It can be proffered, according to
    the rules, for the purposes of appellate
    review, though.
    THE COURT: The Court has ruled.
    -24-
    MR. SMITH: I understand that, Your Honor.
    The
    jury is not in the box right now.
    THE COURT: That is correct.
    MR. SMITH: The Court can't prevent –
    THE COURT: I'm not going to let you go
    through
    a whole line of testimony that the Court has
    already   said  it  is   not  going   to  be
    proffered, so you can address that issue on
    appeal.
    MR. SMITH: Your Honor, for the record, the
    Court is not allowing me to proffer this for
    appellate –
    THE COURT: That is correct.
    MR. SMITH: All right. Note my objection to
    that, Your Honor.
    THE COURT: Noted for the record. Bring the
    jury in.
    In State v. Chapman, 
    294 N.C. 407
    , 
    241 S.E.2d 667
     (1978),
    our Supreme Court held that the failure of the trial court to
    allow    counsel   to   make   an    offer    of   proof   was   a   “regrettable
    judicial mistake.”        Id. at 415, 
    241 S.E.2d at 672
    .                However,
    “where     the     witness     has    already       answered     the    question
    sufficiently to demonstrate the immateriality of the inquiry,
    the judge's refusal to allow the preservation of the answer will
    not be held prejudicial error.”          
    Id.
    -25-
    Here, Defendant argues that the trial court’s refusal to
    allow    him    to   proffer     evidence       regarding          Officer     Pressley’s
    personal knowledge of drinking establishments in the vicinity of
    the     checkpoint      constituted       prejudicial              error.        However,
    Defendant      had   already    pursued     a   similar           line   of   questioning
    during his motion to suppress.
    Assuming, without deciding, that the trial court’s refusal
    to allow Defendant to make an offer of proof constituted error,
    we hold that the error was harmless.                       Defendant has failed to
    show    why    the   evidence   he   elicited         on    this     issue    during    the
    suppression hearing — which was made part of the record at that
    time — was insufficient to preserve this issue for appellate
    review.       See State v. Mackey, 
    352 N.C. 650
    , 660-61, 
    535 S.E.2d 555
    , 560-61 (2000) (while trial court erred in denying party
    opportunity to make offer of proof, trial court's dialogue with
    defense       counsel   was     sufficient       to        establish        substance    of
    proposed testimony such that error was harmless).
    We likewise conclude that no prejudicial error occurred as
    a result of the trial court’s limitation of defense counsel’s
    ability to impeach Officer Pressley’s credibility regarding the
    basis    for    establishing     the   checkpoint            in    this     area.       Even
    assuming arguendo that the trial court erred in not allowing
    -26-
    defense counsel to more fully pursue the line of questioning he
    desired on this issue, we are satisfied that any such error was
    harmless.
    In order to show prejudicial error arising from the trial
    court’s exclusion of evidence, the burden is on the defendant to
    establish that a reasonable possibility exists that a different
    result would have been reached but for the error.               N.C. Gen.
    Stat. § 15A-1443(a) (2011).         Here, in light of the evidence
    regarding Defendant’s slurred speech and red and glassy eyes,
    the odor of alcohol on his breath, his poor performance on the
    field sobriety tests, and his .16 blood alcohol concentration
    level, it is highly unlikely that the jury would have reached a
    different verdict had the trial court allowed more extensive
    cross-examination   on   this   issue.       Accordingly,   Defendant   has
    failed to show prejudicial error.
    Conclusion
    For the reasons stated above, we affirm the trial court’s
    denial of Defendant’s motion to suppress and hold that Defendant
    received a fair trial free from prejudicial error.
    AFFIRMED IN PART; NO ERROR IN PART.
