    -ooOoo-
    The Department of Motor Vehicles (DMV) suspended Heather Bouton’s driver’s
    license after it found she violated Vehicle Code section 13353.2 by driving with a blood
    alcohol concentration (BAC) of 0.08 percent or more. The suspension was upheld after
    an administrative hearing. Bouton appeals from the trial court’s denial of her petition for
    a writ of mandate to overturn the hearing officer’s decision.
    The trial court’s ruling was based on its rejection of the unrebutted testimony of
    Bouton’s expert, who opined that the blood testing procedure used to measure Bouton’s
    BAC was scientifically invalid. The court’s conclusions on this point are inconsistent
    with our holding in Najera v. Shiomoto (2015) 
    241 Cal.App.4th 173
     (Najera). We will
    reverse the judgment and direct the trial court to determine whether the suspension
    should be upheld based on other evidence of Bouton’s condition, evidence independent
    of the blood test.
    FACTS AND PROCEDURAL HISTORY
    According to the police report, Bouton was pulled over at 5:33 p.m. on
    September 13, 2013, after Officers Hernandez and Gomez of the Bakersfield Police
    Department saw her fail to stop behind the crosswalk at a red light. By the time Bouton’s
    car came to a stop, half of it was beyond the crosswalk and in the intersection.
    Hernandez observed that Bouton’s speech was slurred when she responded to questions.
    Bouton denied she had been drinking. Hernandez asked her to get out of the car and walk
    a straight line. Bouton stumbled while attempting the walk. Gomez called for a traffic
    unit to carry out a DUI investigation.
    Officer Brown responded and conducted the investigation at 6:05 p.m. He asked
    Bouton a series of standard questions, and as she answered he observed that she smelled
    faintly of alcohol, had slurred speech and red eyes, and swayed from side to side as she
    sat. She again denied she had been drinking but said she used a prescription medication
    for bipolar disorder. Bouton then consented to take a series of field sobriety tests.
    During the horizontal gaze nystagmus test, Bouton failed to follow the instruction to
    follow a visual stimulus with her eyes. She moved her head instead during repeated
    attempts. Next, during the walk-and-turn test, Bouton failed to keep her balance while
    standing heel-to-toe as Brown explained the test. She swayed from side to side and had
    2.
    to move her foot to regain her balance. When walking, she swayed, failed at each step to
    touch her heel to her toe, and failed to keep her arms at her sides. She also failed to
    follow the instruction to keep her front foot planted while turning. At one point, she
    paused and stood for several seconds before continuing to walk. Finally, during the one-
    leg-stand test, Bouton failed to keep her arms at her sides, failed to count out loud, and
    had to hop and put her foot down to keep her balance.
    Brown next asked Bouton to take a preliminary alcohol screening test (i.e., a
    breath test) and read her the associated admonishment. Bouton began to cry and admitted
    she had had a vodka and tonic that day before driving. She consented to take the breath
    test, which indicated a BAC of 0.21 percent at 6:17 p.m.
    Brown arrested Bouton and advised her pursuant to Vehicle Code section 23612
    that, by driving, she gave her implied consent to a breath or blood test and could choose
    one or the other. Bouton chose to take another breath test. The test involved three
    breaths. Bouton delivered the first breath and the machine indicated a BAC of 0.21 at
    6:32 p.m. She had asthma and was unable to provide sufficient air volume for the
    remainder of the test. She then agreed to submit to a blood test. Brown drove her to
    Kern Medical Center, where her blood was drawn at 7:09 p.m.
    At the time of the arrest, Bouton surrendered her driver’s license to Brown, and he
    served her with a DMV suspension/revocation order form. The order stated that
    Bouton’s driving privilege would be suspended starting 30 days from the order’s date.
    The form included a temporary driver’s license valid for 30 days. It advised Bouton of
    her right to a DMV administrative hearing to challenge the suspension. The DMV later
    stayed her suspension from the expiration of the temporary license until the outcome of
    the administrative hearing.
    Bouton’s blood sample was tested at the Kern Regional Crime Laboratory on
    September 30, 2013. It was found to have a BAC of 0.20 percent.
    3.
    Bouton requested a hearing, which commenced on December 3, 2013 and was
    continued to July 9, 2014. The DMV submitted a sworn statement by the arresting
    officer, the police reports, the blood test report, and Bouton’s driving record.
    Bouton’s expert, a chemist named Janine Arvizu, testified about the procedures
    used by the Kern Regional Crime Laboratory to test Bouton’s blood sample. She made
    several points, only one of which concerns us here. Arvizu said the laboratory used a
    technique called gas chromatography to test for alcohol in a sample. The testing
    apparatus, a machine called a gas chromatograph, has a heated chamber containing two
    narrow, coiled columns each about 30 meters long. The inner surfaces of the columns are
    treated with chemical preparations, a different preparation in each column. A portion of
    the sample to be tested is introduced into each column in gaseous form and pushed
    through by an inert gas, such as helium. As the sample passes through a column,
    compounds in the sample react with the chemicals on the walls of the column. The
    reactivity of the compounds in the sample determines the length of time it takes for those
    compounds to reach the end of the column. Compounds that interact more take longer.
    When a hydrocarbon such as alcohol reaches the end of the column, it is combusted by a
    device called a flame ionization detector. The length of time from insertion of the sample
    to combustion at the detector, known as the retention time, is an indication of the identity
    of the compound.
    The reason for using two differently prepared columns is that, for any given single
    column, the retention time for alcohol is the same as the retention time for numerous
    other volatile organic compounds that can be present in a blood sample. Data from a
    single column consistent with the presence of alcohol would also be consistent with the
    presence of a different compound or alcohol plus another compound. A sample yielding
    a positive result from a single column thus might contain no alcohol or might contain less
    alcohol than the result indicates. Results from the second column, which are based on a
    4.
    different chemical principle, are necessary to confirm the presence and quantity of
    alcohol.
    Arvizu testified that the necessity of confirmation of a BAC result by the second
    column was widely recognized in the scientific community. The American Academy of
    Forensic Sciences, the Society of Forensic Toxicologists, the American Board of
    Forensic Toxicology, and the manufacturers of the gas chromatograph and the columns
    used by the Kern Regional Crime Laboratory all agreed that results from two columns
    must be used for measuring BAC. Arvizu said:
    “[With] a single column, when you get a peak at the same retention
    time that you see for ethanol, scientifically the only thing you can say is it
    might be ethanol, it might be something else entirely, or it might be ethanol
    plus other compound or compounds. That’s all you can say. So you can’t
    identify ethanol with a single column and you can’t tell how much ethanol
    is present with a single column.”
    She also said a single-column result can provide merely a “suggestion that it might
    be ethanol.”
    Arvizu testified that the results for Bouton from the Kern Regional Crime
    Laboratory reflected data from a single column only. For this reason, the results were
    scientifically invalid.
    The DMV presented no evidence in rebuttal to Arvizu’s testimony.
    The hearing officer’s responsibility was to determine whether a preponderance of
    the evidence showed three factors: (1) a police officer had reasonable cause to believe
    Bouton was violating Vehicle Code section 23152 or 23153; (2) Bouton was lawfully
    arrested; and (3) Bouton was driving with a BAC of 0.08 percent or more. (Gananian v.
    Zolin (1995) 
    33 Cal.App.4th 634
    , 638; Veh. Code, § 13557, subd. (b)(3).) The hearing
    officer issued his decision on July 28, 2014. He found the arrest was lawful and the
    arresting officer had reasonable cause to believe Bouton was driving while intoxicated.
    He briefly summarized Arvizu’s testimony and rejected her opinions. On the point at
    5.
    issue in this appeal, the hearing officer’s only remark was that the use of two columns in
    the gas chromatograph was merely “a recommendation from the manufacturer,” although
    “[s]ome organizations require” two. The hearing officer concluded that the DMV’s
    “evidence has not been rebutted” and “more credence was given to the [DMV’s]
    evidence.” The stay on the suspension of Bouton’s license was lifted and the suspension
    was reimposed from August 6, 2014 to December 5, 2014.
    Bouton filed her petition in the trial court on August 5, 2014. Her license
    suspension was again stayed and the matter was heard on December 1, 2014. In a minute
    order issued February 2, 2015, the court found in favor of the DMV. Observing that the
    DMV was entitled to a presumption that it acted in conformity with state regulations, the
    court held that it was required to presume that “single[-]column [gas chromatograph]
    analysis was capable of identifying and quantifying ethyl alcohol concentrations in
    [Bouton’s] blood with precision, and that it did so here.” Then the court found that
    Arvizu’s testimony failed to rebut this presumption. Arvizu did not rely on “calibration
    or similar maintenance records” to show that the laboratory’s gas chromatograph “was
    producing inaccurate results at the time” Bouton’s sample was tested. Further, Arvizu
    did not “testify regarding [Bouton’s] actual BAC, or state that [her] BAC was lower than
    .20 [percent]. No evidence was presented that [Bouton’s] reported .20 [percent] BAC
    was, in fact, wrong.” “The evidence that the test result MIGHT be wrong does not
    overcome the presumption,” the court concluded.
    In addition to finding the blood test results to be valid, the trial court relied on
    corroborating evidence of Bouton’s alcohol intoxication. It pointed to the evidence that
    Bouton drove into the intersection on a red light next to a police car, smelled of alcohol,
    and had red eyes, slurred speech, poor balance, and a breath test result showing a BAC of
    0.21 percent.
    The court entered judgment against Bouton on February 19, 2015. The stay on the
    suspension of her license was lifted.
    6.
    DISCUSSION
    In ruling on a petition for a writ of mandate seeking reversal of the suspension of a
    driver’s license, a trial court must apply its independent judgment to determine whether
    the weight of the evidence supports the administrative decision. (Lake v. Reed (1997) 
    16 Cal.4th 448
    , 456.) We must uphold the trial court’s factual findings if they are supported
    by substantial evidence in the record. In deciding whether there is substantial evidence,
    we resolve all evidentiary conflicts and draw all reasonable inferences in favor of the trial
    court’s decision; and we cannot reverse that decision merely because a different decision
    could also reasonably have been reached. (Id. at p. 457.) To the extent the appeal
    involves pure questions of law, including the interpretation of statutes and regulations, we
    review those questions de novo. (Borger v. Department of Motor Vehicles (2011) 
    192 Cal.App.4th 1118
    , 1121; Manriquez v. Gourley (2003) 
    105 Cal.App.4th 1227
    , 1233
    (Manriquez).)
    At the administrative hearing, the DMV had the burden of proving by a
    preponderance of the evidence that Bouton had a BAC of 0.08 percent or more.
    (Manriquez, supra, 105 Cal.App.4th at p. 1232.) The DMV can do this, however, by
    merely submitting blood alcohol test results recorded on official forms. (Shannon v.
    Gourley (2002) 
    103 Cal.App.4th 60
    , 64 (Shannon).) This is because (1) provisions of
    title 17 of the California Code of Regulations (specifically, Cal. Code Regs., tit. 17,
    § 1215 et seq.) regulate the collection and testing of blood samples for determination of
    alcohol concentration; (2) Evidence Code section 664 creates a rebuttable presumption
    that official duties (such as the duty to follow regulations) have been carried out; and
    (3) Evidence Code section 1280 establishes a hearsay exception for records made by
    public employees. (Shannon, supra, at p. 65.) Consequently, “[t]he recorded test results
    are presumptively valid and the DMV is not required to present additional foundational
    evidence.” (Ibid.)
    7.
    After the DMV has made its initial showing by means of these official test-result
    records, the burden shifts to the driver “to demonstrate that the test was not properly
    performed.” (Imachi v. Department of Motor Vehicles (1992) 
    2 Cal.App.4th 809
    , 817.)
    Among the ways the driver can do this is by showing that the particular machine used to
    test the sample malfunctioned or was improperly calibrated or employed. (People v.
    Vangelder (2013) 
    58 Cal.4th 1
    , 34 (Vangelder).) If the driver does this, the burden of
    proof shifts back to the DMV to show that the results are reliable despite the facts
    presented by the driver. (Manriquez, supra, 105 Cal.App.4th at p. 1233.)
    In this case, it is undisputed that Bouton was lawfully arrested and the officer had
    reasonable cause to believe she was driving under the influence. It also is undisputed that
    the DMV submitted official records adequate to make an initial showing that Bouton was
    driving with a BAC of 0.08 percent or more. The burden of producing evidence to the
    contrary thus was shifted to Bouton. The trial court concluded that Bouton failed to shift
    the burden back to the DMV. This conclusion was based primarily on the view that
    Arvizu’s testimony was inadequate to undermine the blood test results.
    The court’s view was based on an error of law, for the court misapplied the
    presumption of regulatory compliance. The applicable regulation requires blood to be
    tested by a method “capable of the analysis of ethyl alcohol with a specificity which is
    adequate and appropriate for traffic law enforcement.” (Cal. Code Regs., tit. 17,
    § 1220.1, subd. (a)(2).) It is rebuttably presumed that the method employed had this
    capability. Contrary to the trial court’s opinion, however, rebutting this presumption did
    not require Bouton to prove the gas chromatograph was improperly calibrated or
    maintained. It also did not require her to present proof of her actual BAC. A driver can
    rebut the presumption by showing that a testing apparatus was improperly employed
    when the driver’s sample was tested. (Vangelder, supra, 58 Cal.4th at p. 34.)
    The proper employment of the apparatus includes using the data it produces in a
    scientifically valid manner. Arvizu’s uncontroverted testimony showed that the
    8.
    laboratory was not using a valid methodology in the process of getting from the raw data
    produced by the gas chromatograph to the conclusion that the sample had a BAC of 0.08
    or more. The point of her testimony was that, even assuming the machine was working
    correctly with both columns installed, the reported conclusion that Bouton’s sample had a
    BAC of more than 0.08 percent was based on only one column’s data, and, as a matter of
    well-established scientific principle, one column’s data are incapable of supporting this
    conclusion. The trial court stressed that Arvizu did not show the results were incorrect,
    but the possibility that the results of a scientifically invalid procedure might happen to be
    correct by chance hardly shows the presumption of validity to be unrebutted.
    The nature of the trial court’s error is well illustrated by the remark in its minute
    order that Arvizu must be wrong because “the consequence of accepting [Arvizu’s]
    conclusion would be that single[-]column [gas chromatography] analysis would never be
    acceptable, even though it strictly complies with [the applicable regulations in Cal. Code
    Regs., tit. 17].” This remark reflects misunderstanding of both the regulations and the
    testimony. The regulations state that the blood testing method must be capable of alcohol
    analysis adequate for enforcing the law. (Cal. Code Regs., tit. 17, § 1220.1, subd. (a)(2).)
    Arvizu’s testimony, if correct, established that single-column gas chromatography is not
    capable of determining either the presence or the concentration of blood alcohol. This
    means that single-column gas chromatography is indeed never valid and therefore cannot
    comply, strictly or otherwise, with the regulations. The DMV did not attempt to rebut
    Arvizu’s testimony and there is nothing in the record on the basis of which the trial court
    could reasonably have rejected it.
    In so holding, we follow this court’s recent decision in Najera, supra, 
    241 Cal.App.4th 173
    . That case involved the same expert, Arvizu, giving the same
    uncontroverted testimony that single-column gas chromatography was incapable of valid
    measurement of BAC. (Id. at pp. 177-178.) We held (id. at p. 182) that this testimony
    rebutted the presumption that the laboratory was using methodology “capable of the
    9.
    analysis of ethyl alcohol with a specificity which is adequate and appropriate for traffic
    law enforcement.” (Cal. Code Regs., tit. 17, § 1220.1, subd. (a)(2).)
    The above discussion disposes of the DMV’s main argument, that Arvizu’s
    testimony failed to rebut the presumption that the blood test results were valid because
    the regulations are presumed to have been followed. Several additional arguments
    remain to be addressed.
    First, the DMV maintains Najera does not apply here because the procedural
    posture is reversed. There, because the driver won in the trial court, the question was
    only whether Arvizu’s testimony was sufficient to support the trial court’s finding that it
    rebutted the DMV’s prima facie case. Here, the driver lost and the trial court found the
    expert testimony failed to rebut the DMV’s prima facie case, so the question is whether a
    reasonable finder of fact could so conclude. The DMV argues that a reasonable finder of
    fact could do so even if he or she also could find as the trial court did in Najera.
    This attempt to distinguish Najera fails for two reasons. First, the trial court here
    committed legal error in holding that the presumption of regulatory compliance could not
    be rebutted without evidence that the gas chromatograph was improperly maintained and
    calibrated or that Bouton’s BAC was actually below 0.08 percent. In reality, testimony
    like Arvizu’s, attacking the scientific validity of using only one column’s data to
    determine the sample’s BAC, also can rebut the presumption. Second, the DMV
    presented no rebuttal evidence. There is nothing in Arvizu’s testimony or elsewhere in
    the record on the basis of which a reasonable finder of fact could conclude that her
    testimony failed to carry Bouton’s burden and thereby shift the burden back to the DMV.
    Next, the DMV contends “there was no evidence that the crime lab’s failure to
    ‘report’ the results from the second column meant that it did not consider the data from
    both columns.” The record does not support this view. Arvizu testified, in effect, that
    according to her review of the materials provided by the DMV, the reported BAC results
    from the Kern Regional Crime Laboratory were based on data from only one column of
    10.
    the gas chromatograph. There is no other reasonable interpretation of her testimony. The
    trial court interpreted the evidence the same way. It ruled not that the evidence failed to
    show the reported BAC was based on data from only one column, but that it failed to
    show that the lab’s use of a single-column method undermined the presumption of
    regulatory compliance. It would be sheer speculation to say the lab must have employed
    the second-column data even though the materials it provided reflected only one
    column’s results.
    As we held in response to a similar argument in Najera, Arvizu’s testimony
    shifted the burden of proof back to the DMV. The DMV was then obligated to present
    evidence that it used data from both columns, if any such evidence existed. (Najera,
    supra, 241 Cal.App.4th at p. 184.) The DMV presented no such evidence.
    There is a related dispute between the parties about whether raw data from the
    second column was made available to Bouton in discovery. The DMV claims these data
    were supplied in response to a subpoena and were then “made part of” the administrative
    record, although they are not included in the administrative record that the DMV
    provided to Bouton and Bouton lodged in this court. On November 3, 2015, the DMV
    filed a motion in this court to augment the administrative record with a CD purportedly
    containing these data. The DMV admits, however, that “[a] special computer program is
    necessary to review the data files.” Bouton filed an opposition to the motion. The DMV
    argues that Arvizu ought to have analyzed the data from the second column and testified
    about whether they supported the determination that Bouton had a BAC of 0.08 percent
    or more.
    There are multiple reasons for denying the DMV’s motion to augment. The CD is
    unreadable, so even if we granted the motion we would have no more information than if
    we denied it. The DMV claims the CD was made part of the administrative record, but it
    admits in its motion that it was never placed before the trial court, and it does not claim it
    was placed before the hearing officer. There is no indication that the DMV ever
    11.
    attempted to place it before the court or the agency or ever sought to rely on it in the
    court or agency proceedings. Most important, even if we granted the motion, the
    unreadable data could not help the DMV. Bouton never claimed the second column was
    not operating or the gas chromatograph did not generate data from the second column.
    The mere fact that the data existed (and were supplied in unreadable form to Bouton) has
    no bearing on the validity of test results derived without reference to those data. As for
    the DMV’s argument that Arvizu should have found a way to analyze the data and should
    have determined whether they supported or undermined the first-column results on which
    the DMV relied when it suspended Bouton’s license, this was the DMV’s burden, as we
    held in response to a similar argument in Najera, supra, 241 Cal.App.4th at page 183: “If
    Najera’s blood test results really were supported by the data from the second column
    despite the DMV’s failure to use those data when it suspended Najera’s license, it was up
    to the DMV, not Najera, to present evidence to that effect at the hearing.” The motion
    will be denied.
    The DMV also avers that Arvizu could have tested, but did not test, Bouton’s
    blood sample independently, as permitted by a regulation. (Cal. Code Regs., tit. 17,
    § 1219.1, subd. (g).) As we held in Najera, this argument again overlooks the fact that
    the expert testimony shifted the burden back to the DMV. (Najera, supra, 241
    Cal.App.4th at p. 184.)
    Next, the DMV contends there is another aspect of the Evidence Code section 664
    presumption of regulatory compliance that Arvizu’s testimony failed to rebut. The
    California Department of Health Services is required to evaluate a blood laboratory’s
    methods to make sure they satisfy regulatory standards. (Cal. Code Regs., tit. 17,
    § 1220.1, subd. (b).) The DMV says the trial court was required to presume the
    California Department of Health Services did this evaluation and found the Kern
    Regional Crime Laboratory was in compliance. Therefore, according to the DMV, the
    court was compelled to presume the laboratory was found to be using a method “capable
    12.
    of the analysis of ethyl alcohol with a specificity which is adequate and appropriate for
    traffic law enforcement.” (Cal. Code Regs., tit. 17, § 1220.1, subd. (a)(2).) In the
    DMV’s view, this means the court could not rely on expert testimony to find that the
    method used was not, in reality, capable of valid blood alcohol analysis.
    As we stated in Najera, this would be “a presumption too far,” because it would
    contravene the principle that a driver can “‘demonstrate that the test was not properly
    performed.’” It is incorrect because it “would amount to a presumption that anything the
    lab does has been approved and thus is unchallengeable.” (Najera, supra, 241
    Cal.App.4th at p. 183.) A driver can rebut the presumption that the California
    Department of Health Services found a lab’s methods capable of adequate analysis by
    demonstrating that its methods are not, in fact, capable of adequate analysis. That is what
    happened here.
    Finally, the DMV asserts that the data from one column of the gas chromatograph
    should count as at least some evidence to be corroborated by the breath tests, field
    sobriety tests, and other indications of Bouton’s intoxication. The DMV’s thinking here
    is that if a positive result from one column means that some volatile organic compound is
    in the sample at a concentration of 0.08 percent or more, then other evidence, such as the
    driver’s admission to having been drinking, could confirm that the compound is alcohol.
    This reasoning may be superficially attractive, but it does not appear to us to be correct.
    Arvizu testified that a positive result from one column is consistent with alcohol, some
    other compound, or both alcohol and another compound. If a driver has consumed
    alcohol, but not enough alcohol to have a BAC of 0.08 percent, a test result based on data
    from one column could falsely show a BAC of 0.08 percent or more because the sample
    contained both alcohol and another volatile organic compound. For this reason, the lab’s
    failure to use the data from the second column means the test results cannot be used to
    support a finding of a BAC of 0.08 percent or more even in conjunction with behavioral
    evidence of impairment. If this other evidence did not show a BAC of 0.08 percent on its
    13.
    own, the single-column result would not be able to fill the gap, because a single-column
    positive result is always consistent with the presence of alcohol and another compound in
    unknown proportions.
    The DMV cites Coffey v. Shiomoto (2015) 
    60 Cal.4th 1198
     in support of its view
    that the single-column result can be considered in conjunction with behavioral evidence
    even if Arvizu’s testimony rebutted the presumption that the blood test results were
    reliable. Coffey was pulled over for driving erratically. Fifty-six minutes after the stop,
    she took a breath test which showed a BAC of 0.08 percent. Three minutes later, a
    second breath test showed a BAC of 0.09 percent. A blood sample taken 24 minutes after
    that was found to have a BAC of 0.095 or 0.096 percent. Coffey also had red eyes, failed
    field sobriety tests, and smelled of alcohol. (Id. at pp. 1203-1205.) At the DMV hearing,
    her expert testified that the breath and blood test results showed Coffey’s BAC was rising
    from 0.08 percent when she was stopped, so he would expect it to have been below 0.08
    percent while she was driving. (Id. at p. 1205.) The Supreme Court held that this
    testimony rebutted the presumption that the test results showed Coffey was driving with a
    BAC of 0.08 percent or more. (Id. at pp. 1209-1211.) This shifted the burden back to the
    DMV, but the test results could still be considered, in conjunction with the other
    evidence, in determining whether Coffey’s BAC was 0.08 percent while she was driving.
    (Id. at pp. 1211-1217.) In light of this, the Supreme Court concluded that substantial
    evidence supported the trial court’s finding against Coffey. (Id. at pp. 1217-1218.)
    Coffey is distinguishable from this case. In Coffey, the expert’s testimony did not
    indicate anything intrinsically wrong with the test results. He only said the results were
    consistent with Coffey’s BAC being lower before the breath and blood samples were
    taken. There was no evidence that the testing methodology failed to determine validly
    the BAC in the samples. Here, by contrast, the uncontroverted expert testimony showed
    that the blood lab’s methodology was incapable of accurately measuring BAC.
    14.
    The question remains of whether the other evidence—two breath tests showing
    results of 0.21 BAC, poor performance on three field sobriety tests, red eyes, slurred
    speech, a smell of alcohol, and the traffic violation—could establish a BAC of 0.08
    percent or more independently of the blood test. The trial court relied on this evidence in
    part, but the record does not show whether the court considered it sufficient on its own,
    and the parties have not briefed that question. Rather than make the finding in the first
    instance ourselves, we will remand.
    DISPOSITION
    The judgment is reversed. The matter is remanded to the trial court for further
    proceedings consistent with this opinion. The DMV’s motion to augment the record,
    filed on November 3, 2015, is denied. Costs on appeal are awarded to Bouton.
