    UNPUBLISHED OPINION
    KIRK, Judge
    In this appeal following his convictions of third-degree driving under the
    influence, appellant Paul Richard Dehn raises several arguments regarding the legality of
    the traffic stop, the implied-consent process, and the administration of his court trial. We
    affirm.
    FACTS
    Following a traffic stop on October 2, 2010, appellant was charged with two
    counts of third-degree driving while impaired.       Appellant later moved to suppress
    evidence from the stop.      The district court denied appellant’s motion to suppress,
    concluding that the traffic stop was reasonable, appellant was not entitled to a Miranda
    warning, the police officers vindicated appellant’s limited right to counsel, and appellant
    consented to the urine test. The parties then conducted a trial before the district court.
    Following the trial, appellant challenged the state’s introduction of testimony regarding
    appellant’s preliminary breath test (PBT), the Minnesota Bureau of Criminal
    Apprehension (BCA) report regarding appellant’s alcohol concentration, and defense
    counsel’s testimony at trial, and argued that the prosecutor had committed misconduct.
    The district court rejected appellant’s arguments regarding the admission of evidence and
    the prosecutor’s conduct and found appellant guilty of both counts of driving while
    impaired. This appeal follows.1

    Because the state did not file a brief in this appeal, we ordered the matter to be
    determined on the merits pursuant to Minn. R. Civ. App. P. 142.03. A brief from the
    state in this complicated, multi-issue appeal would have been helpful to this court.

    DECISION
    I.     The district court did not err by concluding that the officers were justified in
    conducting a traffic stop of appellant’s vehicle.
    Appellant first argues that the district court erred in concluding that the police
    officers were justified in conducting a traffic stop of his vehicle. When reviewing a
    pretrial order denying a motion to suppress evidence, this court “review[s] the facts to
    determine whether, as a matter of law, the court erred when it failed to suppress the
    evidence.” State v. Flowers, 
    734 N.W.2d 239
    , 247 (Minn. 2007). “[W]e review the
    district court’s factual findings under a clearly erroneous standard and the district court’s
    legal determinations de novo.” State v. Gauster, 
    752 N.W.2d 496
    , 502 (Minn. 2008).
    The United States and Minnesota Constitutions prohibit unreasonable searches and
    seizures. U.S. Const. amend. IV; Minn. Const. art. I, § 10. A police officer’s temporary
    detention of an individual during a traffic stop constitutes a seizure. State v. Thiel, 
    846 N.W.2d 605
    , 610 (Minn. App. 2014), review denied (Minn. Aug. 5, 2014). But “[l]imited
    investigatory stops are allowed if police have reasonable articulable suspicion of a motor
    vehicle violation or of criminal activity.” State v. Johnson, 
    645 N.W.2d 505
    , 508 (Minn.
    App. 2002). To justify an investigatory traffic stop, “the police must only show that the
    stop was not the product of mere whim, caprice or idle curiosity, but was based upon
    specific and articulable facts which, taken together with rational inferences from those
    facts, reasonably warrant that intrusion.” State v. Anderson, 
    683 N.W.2d 818
    , 823 (Minn.
    2004) (quotation omitted).
    3
    “[I]f an officer observes a violation of a traffic law, however insignificant, the
    officer has an objective basis for stopping the vehicle.” State v. George, 
    557 N.W.2d 575
    , 578 (Minn. 1997). But an officer’s observation of a single instance of swerving
    within a traffic lane does not, by itself, create reasonable, articulable suspicion to support
    a traffic stop.    State v. Brechler, 
    412 N.W.2d 367
    , 368-69 (Minn. App. 1987).
    Nevertheless, this court has determined that swerving within a traffic lane and crossing
    over the center line can provide a reasonable, articulable suspicion sufficient to justify a
    traffic stop. See, e.g., State v. Wagner, 
    637 N.W.2d 330
    , 336 (Minn. App. 2001) (finding
    an objective, reasonable basis to conduct a traffic stop when the driver crossed the center
    line and drove on the shoulder); State v. Dalos, 
    635 N.W.2d 94
    , 96 (Minn. App. 2001)
    (holding that “continuous weaving within one’s own lane is sufficient by itself to create a
    reasonable articulable suspicion of criminal activity to support a traffic stop”).
    Here, the district court concluded that the traffic stop was justified because Blue
    Earth County Sheriff’s Deputy Scott Wolfe saw appellant’s vehicle “weave continuously
    within its own lane and cross over the center line on one occasion.” Appellant argues
    that this conclusion was erroneous because his alleged driving conduct was not captured
    on Deputy Wolfe’s squad-car video. But Minnesota does not require driving conduct to
    be captured on a squad-car video in order to find a reasonable, articulable suspicion to
    conduct a traffic stop. See George, 557 N.W.2d at 578 (explaining that an officer’s
    observations can provide an objective basis to conduct a traffic stop). And, even though
    Deputy Wolfe testified on direct examination that the squad-car video recorded
    appellant’s driving conduct, he later clarified that the recording automatically started
    4
    when he turned on his emergency lights to stop appellant’s vehicle so appellant’s prior
    driving conduct was not recorded. The district court specifically “credit[ed] Deputy
    Wolfe’s testimony” regarding appellant’s driving conduct and the timing of the squad-car
    recording. We defer to the district court’s credibility determinations on appeal. State v.
    Klamar, 
    823 N.W.2d 687
    , 691 (Minn. App. 2012).
    The district court’s factual findings regarding appellant’s driving conduct are
    supported by the record. Because Deputy Wolfe observed appellant’s vehicle weave
    within its traffic lane and cross over the center line “at least one time,” the district court
    did not err in finding a reasonable, articulable suspicion of criminal activity sufficient to
    justify the traffic stop. See Wagner, 
    637 N.W.2d at 336
    ; Dalos, 
    635 N.W.2d at 96
    .
    II.    The district court did not err by concluding that appellant was not entitled to
    a Miranda warning.
    Appellant next argues that the district court erred in declining to suppress evidence
    because the state should have advised him of his Miranda rights. “The issue of whether a
    suspect is in custody and therefore entitled to a Miranda warning presents a mixed
    question of law and fact” that requires “independent review of the [district] court’s
    determination regarding custody and the need for a Miranda warning.” State v. Sterling,
    
    834 N.W.2d 162
    , 167-68 (Minn. 2013) (quotations omitted).
    The United States and Minnesota Constitutions protect an individual from
    compelled self-incrimination.      U.S. Const. amend. V; Minn. Const. art. I, § 7.
    “Statements made by a suspect during a custodial interrogation are admissible only if the
    statement was preceded by a Miranda warning. Thus, a Miranda warning is required if a
    5
    suspect is both in custody and subject to interrogation.” State v. Thompson, 
    788 N.W.2d 485
    , 491 (Minn. 2010) (quotation and citations omitted). An individual is in custody if,
    “based on all the surrounding circumstances, a reasonable person under the circumstances
    would believe that he or she was in police custody of the degree associated with formal
    arrest.” 
    Id.
     (quotation omitted).
    Appellant does not clearly state the point at which he believes he was “in
    custody,” but appears to suggest that it was at some point during his conversation with
    Deputy Wolfe, perhaps when Deputy Wolfe took possession of appellant’s driver’s
    license. When a police officer asks questions at the scene to gather information, no
    Miranda warning is required. State v. Walsh, 
    495 N.W.2d 602
    , 604-05 (Minn. 1993).
    Similarly, “Miranda generally does not apply to temporary investigative detentions.”
    State v. Perkins, 
    353 N.W.2d 557
    , 560 (Minn. 1984). Because traffic stops are generally
    temporary, brief, and conducted in public, a stopped motorist is usually not in custody for
    Miranda purposes. State v. Herem, 
    384 N.W.2d 880
    , 882-83 (Minn. 1986). In addition,
    the supreme court has explained that police officers are not required to give a driver a
    Miranda warning before reading the implied-consent advisory and administering a
    chemical test. State v. Gross, 
    335 N.W.2d 509
    , 510 (Minn. 1983) (citing South Dakota v.
    Neville, 
    459 U.S. 553
    , 564 n.15, 
    103 S. Ct. 916
    , 923 n.15 (1983)).
    Citing Herem, the district court concluded that appellant was not in custody during
    the October 2 traffic stop. In Herem, a police officer stopped a speeding motorcyclist,
    escorted him to a patrol car to separate him from his passenger, smelled alcohol, and
    performed a PBT. 384 N.W.2d at 881, 883. The supreme court concluded that the
    6
    motorcyclist was not in custody even though he was questioned in the officer’s patrol car.
    Id. at 883. Here, the district court concluded that there was even less evidence that
    appellant was in custody because he was questioned while sitting in his own vehicle and
    while performing field sobriety tests.
    We agree with the district court’s determination that appellant was not in custody
    during the traffic stop and field sobriety testing.     The traffic stop was fairly brief,
    conducted in public, and no different than other routine traffic stops that are expanded to
    include field sobriety testing. See id. at 882-83. In addition, no caselaw suggests that
    appellant was entitled to a Miranda warning before performing field sobriety tests or
    hearing the implied-consent advisory. See Gross, 335 N.W.2d at 510 (explaining that a
    Miranda warning is not required).        Appellant challenges Gross on the basis that it
    discusses an earlier version of Minnesota’s implied-consent law. But Gross remains
    good law and is consistent with other caselaw in this area. See Walsh, 495 N.W.2d at
    604-05 (“On-the-scene questioning, where the officers are simply trying to get a
    preliminary explanation of a confusing situation, does not require a Miranda warning.”
    (quotation marks omitted)). Because we conclude that appellant was not in custody
    during the traffic stop, he was not entitled to a Miranda warning, and the district court
    properly declined to suppress evidence on that basis.
    III.   The district court did not err by concluding that appellant consented to the
    urine test, the officers vindicated appellant’s right to counsel, and the
    implied-consent statute is constitutional.
    Appellant next raises several arguments regarding Minnesota’s implied-consent
    process, arguing that (1) he did not consent to a warrantless search; (2) he was not
    7
    allowed to vindicate his right to counsel; and (3) the implied-consent process violates
    both his due-process rights and the unconstitutional-conditions doctrine.
    A.     Appellant consented to the urine test.
    The district court concluded that appellant voluntarily consented to the urine test
    because he was read the implied-consent advisory four times, indicated that he
    understood the advisory each time, and was “given ample opportunity to contact an
    attorney.” But appellant argues that his consent to the PBT and urine test were coerced
    because (1) he was confronted by a uniformed and armed police officer; (2) he was
    arrested, handcuffed, and placed in the back of a squad car next to a police dog; and
    (3) he was unable to reach an attorney at 1 a.m. while at the police station. We analyze
    the district court’s finding that consent to search was voluntary for clear error, which
    occurs when “we are left with the definite and firm conviction that a mistake occurred.”
    State v. Diede, 
    795 N.W.2d 836
    , 846-47 (Minn. 2011).
    Collecting and testing a person’s blood, breath, or urine constitutes a search under
    the Fourth Amendment and requires a warrant or an exception to the warrant
    requirement. Ellingson v. Comm’r of Pub. Safety, 
    800 N.W.2d 805
    , 807 (Minn. App.
    2011) (citing Skinner v. Ry. Labor Execs.’ Ass’n, 
    489 U.S. 602
    , 616-17, 
    109 S. Ct. 1402
    ,
    1413 (1989)), review denied (Minn. Aug. 24, 2011). Consent is an exception to the
    warrant requirement. State v. Brooks, 
    838 N.W.2d 563
    , 568 (Minn. 2013), cert. denied,
    
    134 S. Ct. 1799
     (2014). “For a search to fall under the consent exception, the [s]tate must
    show by a preponderance of the evidence that the defendant freely and voluntarily
    consented.” 
    Id.
     “Whether consent is voluntary is determined by examining the totality of
    8
    the circumstances.” 
    Id.
     (quotation omitted). A driver’s decision to take a test is not
    coerced or extracted “simply because Minnesota has attached the penalty of making it a
    crime to refuse the test.” Id. at 570.
    A totality-of-the-circumstances analysis requires consideration of the nature of
    appellant’s encounter with the police and “what was said and how it was said.” See id. at
    569. Deputy Wolfe observed appellant’s vehicle weave in its traffic lane and cross over
    the center line “at least one time.”       When he approached appellant, he observed
    appellant’s glassy and bloodshot eyes, and he detected an odor of alcohol emanating from
    appellant’s breath. Appellant admitted to Deputy Wolfe that he had consumed a few
    beers.     When Mapleton Police Officer Kyley Groby approached appellant, she
    independently smelled a “strong odor of alcohol on [appellant’s] breath,” and observed
    red, glossy, and watery eyes. Appellant told Officer Groby that he had had six drinks.
    Appellant then agreed to perform field sobriety testing, and, after being unable to
    complete the tests, agreed to the PBT.
    Appellant does not challenge the officers’ probable cause to suspect him of driving
    under the influence. And, contrary to appellant’s allegation, the record contains no
    evidence that Deputy Wolfe was armed or that he displayed his weapon in any way to
    intimidate appellant. In addition, even though he was handcuffed and placed in the back
    of a squad car next to a police dog, appellant was read the implied-consent advisory and
    indicated that he wished to consult an attorney. There is no evidence that the presence of
    the police dog in the squad car coerced appellant into consenting to the urine test at the
    police station after he had heard the advisory three more times.
    9
    Based on our review of the record, at the police station, the officers gave appellant
    a station phone, his cell phone, and a phone book. Appellant left a message for his
    attorney and spoke to his wife, but declined to contact any other attorneys. He spent
    much of his time staring at the officers. Appellant heard the implied-consent advisory
    four times and stated that he understood the advisory each time. After hearing the
    advisory for the fourth time, appellant agreed to a blood test, but requested a urine test
    due to his fear of needles.
    No evidence suggests that appellant’s consent “was coerced in the sense that his
    will had been overborne and his capacity for self-determination critically impaired.” See
    id. at 571. Therefore, the district court did not err in concluding that appellant consented
    to the urine test and in denying appellant’s motion to suppress. See id. at 572 (“[T]he fact
    that someone submits to a search after being told that he or she can say no to the search
    supports a finding of voluntariness.”).
    B.     The officers vindicated appellant’s right to counsel.
    “[A]n individual has the right, upon request, to a reasonable opportunity to obtain
    legal advice before deciding whether to submit to chemical testing.”          Friedman v.
    Comm’r of Pub. Safety, 
    473 N.W.2d 828
    , 835 (Minn. 1991). But due to “the evanescent
    nature of the evidence in DWI cases,” the individual only has a limited amount of time to
    contact an attorney. 
    Id.
     “The right to counsel will be considered vindicated if the person
    is provided with a telephone prior to testing and given a reasonable time to contact and
    talk with counsel.” 
    Id.
     (quotation omitted). “The question of whether a person has been
    allowed a reasonable time to consult with an attorney is a mixed question of law and
    10
    fact.” Parsons v. Comm’r of Pub. Safety, 
    488 N.W.2d 500
    , 501 (Minn. App. 1992).
    Once the facts are established, the question becomes one of law. 
    Id.
    Appellant argues that the district court erred in concluding that the officers
    vindicated appellant’s limited right to counsel because (1) the station phone did not work
    the entire time; (2) appellant was subject to verbal abuse by a police officer; (3) appellant
    was not told he could contact an attorney during the fourth reading of the implied-consent
    advisory; and (4) appellant was subject to police intimidation for over an hour. Appellant
    argues that the district court’s findings “cannot be reconciled” with the audio recording of
    the implied-consent process.
    But our review of the audio recording does not support appellant’s allegations.
    The recording does not contradict Officer Groby’s testimony that she immediately gave
    appellant a station phone, his cell phone, and a telephone book at the station. Nor does it
    reveal any “verbal abuse” from the officers or “police intimidation.” There are sections
    of silence where appellant does not appear to be making phone calls, and the officers
    explained that this was his chance to contact an attorney. According to Officer Groby’s
    timeline, appellant was given 30 minutes at the police station to contact an attorney.
    Even though the station phone did not work the entire time, appellant testified that he was
    able to use his cell phone, that he made two phone calls, and that he did not attempt to
    contact another attorney. The mere fact that appellant was unable to reach his attorney
    does not indicate that his consent was coerced. See Kuhn v. Comm’r of Pub. Safety, 
    488 N.W.2d 838
    , 841-42 (Minn. App. 1992) (stating that the right to counsel is vindicated
    11
    even when the driver cannot locate his attorney and does not wish to call another
    attorney), review denied (Minn. Oct. 20, 1992).
    When Officer Groby gave her fourth and final reading of the implied-consent
    advisory, she omitted the section regarding appellant’s right to consult with an attorney.
    The implied-consent law requires a driver to be informed “at the time a test is requested”
    that he “has the right to consult with an attorney, but that this right is limited to the extent
    that it cannot unreasonably delay administration of the test.” Minn. Stat. § 169A.51,
    subd. 2(4) (2010). Appellant apparently suggests that Officer Groby was required to read
    the full advisory, each time, including the time he consented to the urine test. But Officer
    Groby had already read the full advisory three times, and appellant always stated that he
    understood the advisory. The statute does not require the advisory to be read at a specific
    time or multiple times. See id. And the officers were not required to provide appellant
    with an unlimited amount of time to contact his attorney. See Friedman, 473 N.W.2d at
    835. Given appellant’s inability to contact his attorney and his apparent disinterest in
    contacting another attorney, it was reasonable for Officer Groby to skip the paragraph
    about contacting an attorney and to require appellant to “make a decision regarding
    testing in the absence of counsel.” See id. (quotation omitted).
    Appellant also suggests that his case is similar to Davis v. Comm’r of Pub. Safety,
    
    509 N.W.2d 380
     (Minn. App. 1993), aff’d, 
    517 N.W.2d 901
     (Minn. 1994). In Davis, this
    court affirmed the district court’s finding that a driver was not given a reasonable amount
    of time to contact an attorney based on “the early hour of the morning,” the driver’s
    repeated attempts to contact an attorney, and the police officer’s “‘arbitrary’
    12
    determination that her efforts to contact an attorney would be limited to 20 minutes.” 509
    N.W.2d at 385. But the only similarity to Davis is that the driver was attempting to
    contact an attorney in the early morning. See id. Unlike in Davis, where the driver was
    still making phone calls at the end of her 20-minute period, appellant made two phone
    calls in 30 minutes and often sat quietly and stared at the officers.          Under these
    circumstances, the district court did not err by concluding that the officers did not violate
    appellant’s limited right to consult an attorney.        See Kuhn, 
    488 N.W.2d at 841
    (“[R]efusing to try to contact more than one attorney or giving up trying to contact an
    attorney is fundamentally different than making a continued good-faith effort to reach an
    attorney.”).
    C.      Minnesota’s implied-consent law is constitutional and does not violate
    the unconstitutional-conditions doctrine.
    Appellant next challenges the constitutionality of Minnesota’s implied-consent
    law. The constitutionality of a statute is a question of law that this court reviews de novo.
    Rew v. Bergstrom, 
    845 N.W.2d 764
    , 776 (Minn. 2014). “[A] party challenging the
    constitutionality of a statute must demonstrate beyond a reasonable doubt that the statute
    violates a constitutional provision.” State v. Cox, 
    798 N.W.2d 517
    , 519 (Minn. 2011).
    Appellant argues that Minnesota’s implied-consent law is unconstitutional because
    the state was required to obtain a warrant before chemical testing. But, as stated above,
    consent is an exception to the warrant requirement. Brooks, 838 N.W.2d at 568. And
    appellant consented to the urine test.
    13
    Appellant also argues that the implied-consent law is unconstitutional because it
    violated his substantive-due-process rights. But we conclude that appellant has waived
    this argument because he did not raise it before the district court. See Roby v. State, 
    547 N.W.2d 354
    , 357 (Minn. 1996) (explaining that an appellate court will not consider
    matters, including constitutional questions, that were not argued to and considered by the
    district court).
    Finally, appellant argues that the implied-consent procedure violates the
    unconstitutional-conditions doctrine. But “a driver’s decision to agree to take a test is not
    coerced simply because Minnesota has attached the penalty of making it a crime to refuse
    the test.” Brooks, 838 N.W.2d at 570. Because appellant consented to the urine test, he
    cannot establish a violation of the unconstitutional-conditions doctrine.
    IV.    The district court did not err by denying appellant’s motion for a mistrial
    based on prosecutorial misconduct.
    Appellant argues that the prosecutor committed misconduct by (1) eliciting
    testimony regarding appellant’s PBT and (2) calling appellant’s defense counsel to testify
    at trial. When reviewing a claim of prosecutorial misconduct, we “will reverse only if the
    misconduct, when considered in light of the whole trial, impaired the defendant’s right to
    a fair trial.” State v. Powers, 
    654 N.W.2d 667
    , 678 (Minn. 2003). “If the misconduct
    was serious, the misconduct is harmless beyond a reasonable doubt if the verdict rendered
    was surely unattributable to the error. For less serious misconduct, the standard is
    whether the misconduct likely played a substantial part in influencing the jury to
    convict.” 
    Id.
     (quotations and citations omitted).
    14
    Following the trial, appellant moved for a mistrial due to both of his allegations
    regarding prosecutorial misconduct, and the district court denied the motions. We review
    a district court’s denial of a motion for a mistrial for abuse of discretion. State v.
    Manthey, 
    711 N.W.2d 498
    , 506 (Minn. 2006). We reverse the district court’s denial only
    if “there is a reasonable probability that the outcome of the trial would be different if the
    event that prompted the motion had not occurred.” State v. Mahkuk, 
    736 N.W.2d 675
    ,
    689 (Minn. 2007) (quotation omitted).
    A.     The prosecutor did not commit misconduct by eliciting testimony
    regarding appellant’s PBT.
    During Officer Groby’s testimony at trial regarding appellant’s traffic stop and his
    failure to complete the field sobriety tests, the prosecutor asked whether the result of
    appellant’s PBT indicated to her that she had probable cause to invoke the implied-
    consent advisory. The district court overruled appellant’s objection to the prosecutor’s
    reference to the PBT because the prosecutor did not ask for the PBT results.
    In general, preliminary screening test results “must not be used in any court
    action.” Minn. Stat. § 169A.41, subd. 2 (2010). But these test results may be used “to
    prove that a test was properly required of a person.” Id., subd. 2(1). Appellant argues
    that the testimony regarding his PBT was inadmissible under section 169A.41,
    subdivision 2, and that, therefore, the prosecutor committed misconduct. See State v.
    Fields, 
    730 N.W.2d 777
    , 782 (Minn. 2007) (“[A]ttempting to elicit or actually eliciting
    clearly inadmissible evidence may constitute misconduct.”).
    15
    But the district court correctly concluded that appellant’s PBT test results were not
    introduced at trial. Officer Groby merely indicated that the PBT created probable cause
    to invoke the implied-consent advisory. She did not discuss the test results or imply that
    appellant’s PBT was “over the legal limit,” as appellant suggests. Moreover, appellant’s
    trial occurred before the district court, and the judge understood that the PBT was only
    mentioned “to prove that a test was properly required” of appellant. See Minn. Stat.
    § 169A.41, subd. 2(1). We conclude that the prosecutor did not commit misconduct by
    mentioning appellant’s PBT, and the district court did not abuse its discretion by denying
    appellant’s motion for a mistrial.
    B.     The prosecutor did not commit misconduct by calling defense counsel
    to testify.
    At trial, Dr. Kathryn Fuller, Ph.D., a forensic scientist from the BCA, testified
    regarding the results of appellant’s urine test.     Appellant’s attorney challenged this
    testimony, claiming that the state did not disclose Dr. Fuller as an expert witness. In
    response, the prosecutor argued that appellant’s attorney “had complete notice of who
    this witness would be,” and the district court overruled appellant’s objection. Following
    Dr. Fuller’s testimony, the prosecutor called appellant’s attorney to the stand “to inquire
    as to whether or not he received discovery in this case” regarding Dr. Fuller’s
    qualifications. The defense attorney testified that someone on his staff had contacted Dr.
    Fuller before the trial, that he knew the state intended to call Dr. Fuller as a witness, and
    that he had received the state’s discovery regarding Dr. Fuller.
    16
    Appellant argues that the prosecutor violated his Sixth Amendment right to
    counsel when he called his defense attorney as a witness. See U.S. Const. amend. VI;
    Minn. Const. art. I, § 6.      In doing so, appellant relies on an appellate case from
    Washington, State v. Regan, 
    177 P.3d 783
     (Wash. App. 2008). In Regan, the Washington
    Court of Appeals explained that the district court has broad discretion when allowing the
    prosecutor to call the defense counsel as a witness. 
    177 P.3d at 786
    . But the district
    court must balance “the right of the state to prove its case . . . and the right of the accused
    to have unhampered and effective representation.”           
    Id. at 787
     (quotation omitted).
    Washington allows a prosecutor to call a defense attorney as a witness when the defense
    attorney’s testimony “is both necessary and unobtainable from other sources.” 
    Id. at 788
    .
    Minnesota does not have a similar rule. See Minn. R. Prof. Conduct 3.7(a) (requiring an
    attorney who is a necessary witness to withdraw from the representation). And no
    caselaw suggests that Minnesota has adopted a balancing test like that in Regan for
    evaluating the admissibility of defense-attorney testimony. Appellant’s (and the district
    court’s) citation to Regan is therefore unpersuasive.
    We conclude that the prosecutor did not commit misconduct by calling appellant’s
    attorney to testify about this limited discovery topic and that, even if he did, the
    attorney’s testimony did not impair appellant’s right to a fair trial. See Powers, 654
    N.W.2d at 678. In fact, the attorney’s testimony was likely irrelevant to the district
    court’s decision to convict appellant of driving under the influence. See id. At this point
    in the trial, the district court had already overruled appellant’s objection to Dr. Fuller’s
    testimony and had allowed the prosecutor to establish her as an expert. And appellant’s
    17
    attorney cross-examined Dr. Fuller regarding the content of her report. In addition, the
    district court stated that it had independently evaluated the credibility of each witness
    before reaching its verdict. We again conclude that the district court did not abuse its
    discretion in denying appellant’s motion for a mistrial.
    V.     The district court did not err in its evidentiary rulings.
    Finally, appellant argues that the state introduced the BCA report containing his
    urine test result without laying proper foundation, and that the introduction of this report
    violated his rights under the Confrontation Clause. “Evidentiary rulings rest within the
    sound discretion of the [district] court and will not be reversed absent a clear abuse of
    discretion.”   State v. Amos, 
    658 N.W.2d 201
    , 203 (Minn. 2003).              The erroneous
    admission of evidence does not require reversal unless the error “substantially
    influence[d] the jury’s decision.” State v. Nunn, 
    561 N.W.2d 902
    , 907 (Minn. 1997).
    “But whether the admission of evidence violates a criminal defendant’s rights under the
    Confrontation Clause is a question of law this court reviews de novo.” State v. Caulfield,
    
    722 N.W.2d 304
    , 308 (Minn. 2006).
    A defendant has a constitutional right to confront the witnesses against him at trial.
    U.S. Const. amend. VI. Admitting a BCA report without the testimony of the BCA
    analyst who prepared it violates a defendant’s confrontation-clause rights. See Caulfield,
    722 N.W.2d at 306-07. But here, Dr. Fuller, the BCA analyst who prepared the report,
    testified at trial, providing appellant with the opportunity to confront the evidence against
    him. Nevertheless, appellant argues that he was unable to confront the evidence against
    him because the state did not introduce his urine sample into evidence. But appellant
    18
    cites no caselaw suggesting that the state must introduce a physical urine sample to
    enable a defendant to confront the evidence against him. Dr. Fuller was qualified to
    testify to the results of appellant’s chemical test, and appellant was allowed to cross-
    examine her.
    At trial, the district court appears to have allowed the introduction of the BCA
    report as a business record, although it did not specifically state its reasoning on the
    record. But, in its written order, the district court explained that the BCA report was
    admissible under Minn. R. Evid. 901. Under rule 901, “authentication or identification”
    is a condition precedent to the admissibility of evidence. Minn. R. Evid. 901(a). This
    requirement “is satisfied by evidence sufficient to support a finding that the matter in
    question is what its proponent claims.” Id. Appellant does not challenge the district
    court’s determination that the BCA report was admissible under rule 901.
    Finally, appellant argues that the state did not establish which testing method the
    BCA used to test appellant’s urine sample. But the officers testified that they collected
    appellant’s urine sample, completed the required paperwork, and mailed the sample to the
    BCA. The BCA then created a laboratory-analysis-request form regarding appellant’s
    sample collected at 1:32 a.m. on October 2, 2010, and provided a kit number to the
    sample. It later created a written report with the same kit number and date and time of
    collection, listing an alcohol concentration of .22. Dr. Fuller testified that she tested
    appellant’s sample, following all BCA protocols, and that she authored the BCA report.
    Appellant cross-examined Dr. Fuller, but did not question her testing method. As the
    district court stated, “[a]ny doubt as to whether the sample Dr. Fuller received and tested
    19
    was in fact [appellant’s] sample[] is fanciful and capricious.” We conclude that the
    district court did not abuse its discretion in admitting the BCA report into evidence.
