    CERTIFIED FOR PUBLICATION
    IN THE COURT OF APPEAL OF THE STATE OF CALIFORNIA
    SIXTH APPELLATE DISTRICT
    THE PEOPLE,                                          H047360
    (Santa Clara County
    Plaintiff and Respondent,                  Super. Ct. No. C1894504)
    v.
    ERNESTO AYON,
    Defendant and Appellant.
    After the police saw defendant Ernesto Ayon commit two minor traffic violations,
    they stopped him in his car and detained him until a narcotics dog arrived. After the dog
    alerted to the presence of drugs, the police searched the car, wherein they found cocaine,
    methamphetamine, currency, and a scale. The trial court denied Ayon’s motion to
    suppress the fruits of the search, and he pleaded no contest to five drug-related counts.
    Ayon appeals from the denial of the motion to suppress. He contends the police
    unlawfully prolonged the duration of the stop in violation of his Fourth Amendment
    rights.
    A careful reading of the record shows the stop was actually part of a preexisting
    drug investigation, and the police used the traffic infractions as pretext for the stop.
    While that fact does not by itself render the search unconstitutional, based on the
    evidence in the record viewed objectively—including police body camera videos of the
    stop—we hold the police unlawfully prolonged the traffic stop.
    I. FACTUAL AND PROCEDURAL BACKGROUND
    A. Procedural Background
    The prosecution charged Ayon with five counts: count 1—transportation of
    cocaine (Health & Saf. Code, § 11352, subd. (a)); count 2—transportation of
    methamphetamine (Health & Saf. Code, § 11379, subd. (a)); count 3—possession of a
    false compartment for storing controlled substances (Health & Saf. Code, § 11366.8,
    subd. (a)); count 4—possession for sale of cocaine (Health & Saf. Code, § 11351); and
    count 5—possession for sale of methamphetamine (Health & Saf. Code, § 11378).
    Ayon moved to suppress the fruits of the search, and the trial court held hearings
    on the motion as set forth below. After the hearings, the trial court denied the motion to
    suppress.
    Ayon then pleaded no contest to all five counts. The court suspended imposition
    of sentence and granted a five-year term of probation to include one year in county jail.
    B. Facts of the Stop
    At the hearings on the motion to suppress, the prosecution presented the testimony
    of two police officers who had participated in the stop and search: Officer Scott
    Williams, who questioned Ayon during the search, and Officer Tony Diep, who handled
    the narcotics dog used to search Ayon’s car. Defense counsel introduced two videos
    containing body camera footage from two officers and partial transcripts of those videos.1
    1. Factual Overview
    Ayon was driving on West Taylor Street in San Jose around 9:00 p.m. on June 19,
    2018. Multiple law enforcement vehicles were behind him, including at least one
    plainclothes police officer. As Ayon was approaching the intersection at North San
    Pedro Street, he drove in the bicycle lane for about 50 to 70 feet before the start of the
    broken line where the right turn lane begins. As he approached the intersection, Ayon
    1
    We do not rely on defense counsel’s transcripts.
    2
    turned on his right turn signal to make a right turn onto North San Pedro Street, but the
    signal did not light up until Ayon had reached the crosswalk.
    After Ayon completed the turn and drove for about two or three blocks on North
    San Pedro Street, the police stopped him, and an officer began questioning him as he sat
    in the car. The police took Ayon’s license and registration, and transmitted his
    information to a dispatcher. About three and a half minutes into the stop, police ordered
    Ayon out of the car, and Officer Williams began questioning him.
    Officer Williams asked Ayon for consent to search his car, but Ayon declined.
    After Ayon refused to consent to the search, the police used a narcotics dog to sniff
    around the outside of the car. After the dog “alerted,” police searched the car and found
    $6,200 hidden in a compartment under the driver’s side of the dashboard. An officer then
    discovered a secret compartment under the back seat of the car. The compartment had
    been designed to be opened with a secret switch, and the officer could not find the switch
    during the initial stop. After taking Ayon into custody, the police took the car to the
    department garage, where they forced the compartment open. Inside, they found 1,132
    grams of cocaine; 73.5 grams of methamphetamine; and an additional $10,000 in
    currency. The police never obtained any warrants for the search or arrest.
    2. Timeline of the Stop and Search
    Defense counsel introduced body camera videos from two of the officers at the
    scene of the stop: Officer Burnett, who was one of the officers who first stopped Ayon,
    and Officer Williams, who conducted most of the questioning of Ayon. The videos from
    both officers’ cameras were time stamped, and the two body cameras recorded many of
    the same events, but from two different angles. Comparing the simultaneous audio and
    video of those events with the time stamps on the two videos shows they were both
    synchronized to the same clock. The time stamps on the body cameras thereby establish
    an unambiguous timeline for the stop.
    3
    Officer Burnett’s body camera began recording as soon as his car pulled up behind
    Ayon’s car. The video shows Ayon’s car had already stopped. Officer Burnett exited the
    passenger’s side of his car and stood behind the right rear corner of Ayon’s car while
    shining a flashlight into it. About a minute into the stop, another officer (identified later
    as Officer Vallejo) approached Ayon at the driver’s side of his car and began talking to
    him. A third officer stood on the passenger’s side and shined a flashlight into Ayon’s car.
    About 20 seconds later, Officer Burnett transmitted Ayon’s license plate number over the
    police radio, while Officer Vallejo returned to his car with what appears to be Ayon’s
    license and registration in his hand. About two minutes into the stop, Officer Burnett’s
    body camera shows him holding and examining Ayon’s license and registration. About
    thirty seconds later, Officer Burnett transmitted Ayon’s name and birthdate over the
    police radio.
    Officer Williams’s body camera started recording at two minutes and 15 seconds
    into the stop. The video shows him approaching the area of the stop from several car
    lengths behind it. About three minutes into the stop, Officer Williams approached
    Officer Burnett at his car and Officer Burnett handed Ayon’s documents to Officer
    Williams. Officer Williams then gave the documents back to Officer Burnett, who got
    into his car with the documents in his hand.
    Around three and half minutes into the stop, Officer Williams and another officer
    approached Ayon’s car and asked him to get out, whereupon Ayon did so and an officer
    patted him down.
    At three minutes and 32 seconds into the stop, the police radio reported back with
    the “returns” from Ayon’s license, registration, and identifying information. The audio
    from the radio is obscured, but the word “valid” was transmitted.
    Officer Williams then asked Ayon to walk to the police car behind them, where
    Officer Williams began talking with Ayon. Officer Burnett got out of his car and stood
    4
    next to them with Ayon’s documents in his hand. Officer Williams told Ayon the police
    had stopped him because he had crossed into a bicycle lane.
    At about four minutes and 20 seconds into the stop, Officer Williams asked Ayon
    if the police could “take a quick look” in his car. Ayon responded, “Um, you guys can,
    but I mean, for an infraction, for a moving violation?” Officer Williams said it was a
    “simple question” police ask as part of a traffic stop. Ayon again asked, “For a moving
    violation, I mean, don’t I get a ticket and get on my way?” Officer Williams again
    asserted that it was part of the traffic investigation. Ayon stated his position that the law
    would not allow police to search his car for a traffic infraction, and the two men debated
    back and forth about whether that was accurate.
    At that point, Officer Williams accused Ayon of “getting very hostile” and “very
    confrontational.”2 When Officer Williams asked again for consent to search the car,
    Ayon declined. Six minutes had elapsed since the start of the stop.
    Immediately after Ayon declined to consent to a search, Officer Williams turned
    Ayon around, handcuffed his hands behind him, and told him he was arresting or
    detaining him “for my safety because of the way you’re acting.” After Ayon objected to
    being handcuffed for a traffic infraction, Officer Williams again asserted he handcuffed
    Ayon for “officer safety because you’re being very aggressive.” Officer Burnett
    continued to stand next to them with Ayon’s documents in his hand.
    At about eight minutes into the stop, Officer Williams asked another officer, “Did
    we request a narco dog yet?” Officer Williams also inquired over the police radio
    whether there were any “narco dogs” that could be brought the location.
    Officer Williams then began questioning Ayon about whether he had been using
    drugs. When Ayon said he had not, Officer Williams performed two physical tests on
    2
    The Attorney General concedes that at no time during the stop did Ayon act
    angrily, raise his voice, make any aggressive movement, or behave in any objectively
    hostile manner.
    5
    Ayon: Officer Williams examined his eyes with a flashlight and checked his pulse. The
    tests were completed by nine minutes and 45 seconds into the stop. For the next three
    minutes, Officer Williams continued to talk and stated he suspected Ayon was under the
    influence of drugs because Ayon was “acting strange.” Officer Williams continued
    talking to Ayon and explained at length his reasons for stopping Ayon and the procedures
    that police follow during a traffic stop.
    At 12 minutes and 45 seconds into the stop, Officer Diep arrived with a narcotics
    dog, and Officer Williams paused his interaction with Ayon to brief Officer Diep. At 13
    minutes into the stop, Officer Williams asked Officer Diep to “just run the dog by the car
    real quick.” For the next two or three minutes, Officers Williams and Burnett chatted
    with Ayon about miscellaneous topics or walked around nearby. At 14 minutes into the
    stop, Officer Williams made a request over police radio to run Ayon “statewide for any
    convictions.”
    At about 15 and a half minutes into the stop, Officer Burnett’s body camera shows
    Officer Diep walking the narcotics dog towards Ayon’s car, and an officer asks Officer
    Williams “to give the dog a little room to work,” whereupon Officer Williams moves
    Ayon further away from the area of the car. Officer Williams continued to chat casually
    with Ayon while Officer Burnett began writing on a yellow index card. Officer
    Williams’s body camera shows other officers standing around the area of the stop.
    At 18 minutes and 45 seconds into the stop, Officer Williams was talking to Ayon
    when Officer Diep approached Officer Williams to report on the narcotics dog sniff. The
    two officers walked back to Ayon’s car. At 19 minutes into the stop, Officer Diep told
    Officer Williams the narcotics dog had alerted at the rear passenger area on the driver’s
    side.
    Officer Williams turned off his body camera soon thereafter, stating “end contact.”
    Audio from Officer Burnett’s body camera shows Williams remained at the scene for
    some time and continued to interact with Ayon, among other things.
    6
    While Officer Williams searched Ayon’s vehicle, Officer Burnett talked with
    Ayon. When Ayon raised the matter of the traffic infractions, Officer Burnett responded,
    “I generally don’t make traffic stops to give tickets. I don’t. That’s not my intent.
    That’s not why I’m making the stop. My intent is to make traffic stops, is to, and then in
    turn prevent crime from happening. Which is, i.e., guns, gangs, narcotics. I mean,
    warrants, parolee, probation, making sure they’re doing all their things right.”
    Officer Burnett’s body camera continued to record for a total of 61 minutes, at
    which time the stop and search was still underway.
    3. Officer’s Williams’s Testimony
    Officer Williams was assigned to the San Jose Police Department’s Metro Unit,
    which specializes in narcotics investigations. He testified that he was driving two cars
    behind Ayon’s vehicle prior to the stop. A police sergeant’s car was directly behind
    Ayon. Officer Williams saw Ayon’s vehicle cross into the bicycle lane on West Taylor
    Street, and Ayon illuminated his turn signal for the turn onto North San Pedro Street as
    the car entered the intersection. Officer Williams contacted the sergeant, who in turn
    instructed another police unit to make the stop. After the other officers stopped Ayon,
    Officer Williams parked, “donned a department-approved uniform,” and approached the
    area of the stop.
    Officer Williams testified that it is standard procedure in a traffic stop to contact
    the driver, request the driver’s license and registration, and transmit the information to a
    radio dispatcher for a records check. They also make a check for “warrants and wants of
    an individual.” Officer Williams testified that it generally takes a radio dispatcher three
    to five minutes to respond to a records request. Officers Burnett and Vallejo were the
    officers who conducted that request. Officer Williams testified that Ayon came back
    “clear,” meaning he was “not wanted, valid driver’s license.” That information came
    back within three to five minutes.
    7
    Officer Williams testified that when he asked Ayon to step out of the car, Ayon
    appeared nervous, and all the windows of his car had been rolled down.3 While Officer
    Williams explained to Ayon the reason for the traffic stop, Ayon was sweating even
    though it was not a “really hot night.”4 While Officer Williams was talking, Ayon
    became agitated and interrupted him. Based on these signs, Officer Williams suspected
    Ayon was under the influence of a controlled substance, so Officer Williams requested a
    narcotics dog.5
    Officer Williams testified that he then performed sobriety tests on Ayon. Officer
    Williams testified, “I also was concerned because I asked him to close his eyes for a
    period of approximately 30 seconds and during that time he continuously would open his
    eyes.”6 Officer Williams testified that fluttering eyes are a sign of being under the
    influence. Officer Williams examined Ayon’s pupils to see if they were dilated, and
    Officer Williams checked Ayon’s pulse.7
    Officer Williams testified that while he was interacting with Ayon, Officer Burnett
    was “standing by with me, I don’t know exactly what he was doing. He was more or
    3
    The videos show Ayon had rolled down the front window on the driver’s side to
    speak with the police, but the windows on the passenger’s side had not been rolled down.
    4
    The videos do not show any visible signs of sweat on Ayon.
    5
    Officer Diep, who handled the narcotics dog, testified he had been informed in
    advance of the car stop that his presence would be required. When defense counsel
    attempted to question him about this further, the trial court sustained the prosecution’s
    objection on relevance grounds.
    6
    The videos show this never occurred. Officer Williams twice asked Ayon to
    close his eyes, and Ayon did so both times. The second time, Officer Williams shined a
    flashlight into Ayon’s closed eyes and they remained closed. Officer Williams never
    asked Ayon to close his eyes “for a period of approximately 30 seconds.” When defense
    counsel attempted to cross-examine Officer Williams about this discrepancy, the trial
    court sustained multiple objections.
    7
    The prosecution did not ask Officer Williams whether Ayon’s eyes were in fact
    dilated or what Ayon’s pulse was. Officer Williams testified on cross-examination that
    there was “very little change in the pupils” in response to the artificial light. There is no
    evidence in the record about the results of the pulse test.
    8
    less standing by with me being security, if you will, just watching.” Officer Williams did
    not know what Officer Vallejo was doing. Officer Williams was not sure what time the
    radio dispatcher responded to the records check because Officer Burnett was handling
    that. Officer Burnett also filled out a field identification card.
    Officer Williams testified that Officer Diep arrived “somewhere around ten
    minutes” from the start of the stop. Officer Williams briefed Officer Diep, whereupon
    Officer Diep returned to his car to retrieve the narcotics dog. Officer Williams testified
    that the dog sniff took “a minute, maybe two minutes at most,” and Officer Diep reported
    back that the dog had alerted.8
    When Officer Williams was asked on cross-examination whether it could have
    been 19 or 20 minutes from the time of the initial stop before the dog alerted, he
    responded, “Somewhere around in that area.” Officer Williams conceded that he never
    did anything “to further the issuance of the Vehicle Code violation ticket.” Once the
    search took place, Officer Williams never did anything further to investigate whether
    Ayon was under the influence of a controlled substance. The police never took a blood
    or urine test.
    4. The Trial Court’s Findings
    The trial court found that the police did not have probable cause to search the car
    based solely on the suspicion Ayon was under the influence of a controlled substance.
    The prosecution argued instead that probable cause for the car search was established
    when the narcotics dog alerted. With respect to the timeline leading up to the arrival of
    the narcotics dog, the trial court found that the narcotics dog arrived and began sniffing
    the car approximately 10 to 11 minutes after the start of the stop. The trial court did not
    make any finding as to when the dog alerted.
    8
    Officer Williams’s body camera shows that five minutes and 50 seconds elapsed
    from the time he asked Officer Diep to conduct the dog sniff to the time when Officer
    Diep reported back.
    9
    As to whether Ayon prolonged the search himself by acting in a hostile manner
    and interrupting Officer Williams, the court stated, “I will simply note this within the
    body-camera footage and as depicted and reflected in the transcripts that were received in
    evidence as well, the following takes place between the officer and the defendant. The
    officer says, ‘I asked you a yes-or-no question and you’re being very hostile towards me.’
    And Mr. Ayon says, ‘Yeah, yeah, yeah, I know that.’ ”
    The court then found that under the totality of the circumstances, the police did not
    unduly or unreasonably prolong the detention. The court found “the officer’s actions
    were objectively reasonable under the circumstances of this particular case” and “the time
    spent interacting with the defendant before the dog determined probable cause” was
    objectively reasonable to pursue “legitimate investigative pursuits.”
    II. DISCUSSION
    Ayon contends the trial court erred in denying his motion to suppress because the
    police unlawfully prolonged the traffic stop. He concedes he committed the traffic
    infractions that justified the initial stop, but he argues the stop became unlawful once
    police extended the detention for reasons unrelated to the purpose of the stop. The
    Attorney General contends the stop was lawful because it did not extend beyond the time
    required to perform ordinary traffic stop inquiries. For the reasons below, we hold the
    police unlawfully prolonged the stop.
    A. Legal Principles
    “A seizure for a traffic violation justifies a police investigation of that violation.”
    (Rodriguez v. U.S. (2015) 
    575 U.S. 348
    , 354 (Rodriguez).) A traffic stop begins once the
    vehicle is pulled over for investigation of the traffic violation. (People v. McDaniel
    (2021) 
    12 Cal.5th 97
    , 130.)
    Because the traffic violation is the purpose of the stop, the stop “may ‘last no
    longer than is necessary to effectuate th[at] purpose.’ [Citation.]” (Rodriguez, supra,
    575 U.S. at p. 354.) “[T]he tolerable duration of police inquiries in the traffic-stop
    10
    context is determined by the seizure’s ‘mission’—to address the traffic violation that
    warranted the stop, [citation] and attend to related safety concerns.” (Ibid.) “A police
    stop exceeding the time needed to handle the matter for which the stop was made violates
    the Constitution’s shield against unreasonable seizures. A seizure justified only by a
    police-observed traffic violation, therefore, ‘become[s] unlawful if it is prolonged beyond
    the time reasonably required to complete th[e] mission’ of issuing a ticket for the
    violation. [Citation.]” (Id. at pp. 350–351.) “Beyond determining whether to issue a
    traffic ticket, an officer’s mission includes ‘ordinary inquiries incident to [the traffic]
    stop.’ [Citation.] Typically such inquiries involve checking the driver’s license,
    determining whether there are outstanding warrants against the driver, and inspecting the
    automobile’s registration and proof of insurance. [Citation.]” (Id. at p. 355.) “There is
    no set time limit for a permissible investigative stop; the question is whether the police
    diligently pursued a means of investigation reasonably designed to confirm or dispel their
    suspicions quickly.” (People v. Russell (2000) 
    81 Cal.App.4th 96
    , 102 (Russell).) An
    officer “may conduct certain unrelated checks during an otherwise lawful traffic stop.”
    (Rodriguez, supra, 575 U.S. at p. 355.) But the officer may not do so “in a way that
    prolongs the stop, absent the reasonable suspicion ordinarily demanded to justify
    detaining an individual.” (Ibid.)
    “The standard of appellate review of a trial court’s ruling on a motion to suppress
    is well established. We defer to the trial court’s factual findings, express or implied,
    where supported by substantial evidence. In determining whether, on the facts so found,
    the search or seizure was reasonable under the Fourth Amendment, we exercise our
    independent judgment. [Citations.]” (People v. Glaser (1995) 
    11 Cal.4th 354
    , 362
    (Glaser).) “Although our review of factual determinations is deferential, it is not without
    limit. Factual determinations must be supported by substantial evidence.” (People v.
    Morton (2003) 
    114 Cal.App.4th 1039
    , 1048.) To satisfy the substantial evidence
    11
    standard, the evidence supporting the trial court’s findings must be “reasonable, credible,
    and of solid value.” (People v. Elder (2017) 
    11 Cal.App.5th 123
    , 130 (Elder).)
    B. The Police Unlawfully Prolonged the Stop
    At the hearing, the prosecution took the position that probable cause for the car
    search arose during the sniff by the narcotics dog. It is well-established that an alert by a
    narcotics dog gives rise to probable cause for a vehicle search. (Florida v. Harris (2013)
    
    568 U.S. 237
    , 248.) Accordingly, the relevant time frame started from the point at which
    the car was first pulled over and ended once the dog alerted to the presence of drugs in
    the car. The issue is whether police diligently pursued their investigation of the traffic
    infractions during that time. As detailed below, they did not.
    When Officer Burnett pulled up behind Ayon’s car and turned on his body camera,
    Ayon’s car had already stopped. The record does not show exactly how long Ayon was
    stopped before Officer Burnett arrived, but the traffic stop had clearly been initiated by
    that point. Accordingly, for the purposes of establishing a timeline, we will assume the
    stop began when Officer Burnett pulled up behind Ayon and turned on his body camera.
    Typical inquiries involved in a traffic stop include “checking the driver’s license,
    determining whether there are outstanding warrants against the driver, and inspecting the
    automobile’s registration and proof of insurance.” (Rodriguez, supra, 575 U.S. at
    p. 355.) After stopping Ayon and looking into his car with flashlights, the police
    approached him, collected his driver’s license and registration, and called the information
    into the police radio for a records check. This took two minutes and 30 seconds. Officer
    Williams testified that a radio check of a driver’s record typically takes about three to
    five minutes. In this case, the police radio dispatcher responded to the records request at
    three minutes and 32 seconds into the stop. Ayon’s driver license was valid, there were
    no “wants” for him, and there is no evidence that anything transmitted by the dispatcher
    would have justified further investigation.
    12
    At no point, however, did any officer begin writing a traffic citation. To the
    contrary, the body camera video shows Officer Williams completely ignored the police
    radio response to the records check. He testified that he was not sure when the response
    came because, “Officer Burnett was handling that aspect of it.” After the radio response
    to the records check, Officer Burnett stood next to Officer Williams for the next 12
    minutes, at which point Officer Burnett got into his car and began writing on a yellow
    index card. Multiple other officers stood or walked around the scene of the stop during
    this period. Nothing in the record shows them doing anything to address the traffic
    infractions.
    Officer Diep did not arrive with the narcotics dog until 12 minutes and 45 seconds
    into the stop. At that point, Officer Williams briefed Officer Diep, and Officer Diep went
    back to the car to retrieve the dog. It appears the sniff test began around 15 and a half
    minutes into the stop. At 18 minutes and 45 seconds into the stop, Officer Diep had
    completed the dog sniff and reported back to Officer Williams to tell him the dog had
    alerted. The videos do not show exactly when the dog alerted, but Officer Diep testified
    that it happened about 15 or 20 seconds before he reported back to Officer Williams. At
    this point in the stop, police had developed probable cause to search the vehicle.
    Accordingly, the record shows that more than 18 minutes had elapsed from the start of
    the stop before police had established probable cause to search the vehicle.
    The Attorney General relies on the trial court’s finding that the narcotics dog
    arrived around 10 to 11 minutes after the traffic stop began. The trial court did not
    explain how it calculated the time, but the timeline of the events as established by the
    videos shows this finding to be imprecise. Both officers’ body cameras show that Officer
    Williams first spoke with Officer Diep at 12 minutes and 45 seconds, and Officer
    13
    Williams first asked Officer Diep to conduct the dog sniff at 13 minutes into the stop.9
    We do not defer to the trial court’s finding on this point as substantial evidence does not
    support it. More importantly, the relevant event for Fourth Amendment purposes was the
    narcotics dog’s alert to the presence of drugs. (Rodriguez, supra, 575 U.S. at p. 357.)
    The trial court made no finding about when that occurred, and the record establishes that
    the alert did not occur until more than 18 minutes into the stop.
    Based on these events, we hold the police failed to diligently address the traffic
    infractions during the stop. They initially conducted the stop in standard fashion by
    taking Ayon’s documents and requesting a records check over the police radio, but that
    portion of the investigation was completed within the first three and a half minutes of the
    stop. Officer Williams spent about a minute talking with Ayon about the traffic
    infractions, and after explaining the reason for the stop, Officer Williams requested
    consent to search the car. By his own admission, Officer Williams never did anything
    after that point in time to investigate the traffic infractions.
    Officer Williams testified that Ayon himself prolonged the stop by interrupting
    Officer Williams and arguing with him. The videos show Ayon asking why it was
    necessary for police to detain him, handcuff him, and search the car for a traffic
    infraction. Ayon stated that the police were violating his legal rights, and he refused to
    consent to a search, but Ayon acted entirely within his rights at all times. The video
    evidence shows he did not raise his voice at any point, and although he verbally
    interrupted Officer Williams, he made no hostile, aggressive, or threatening movements.
    Regardless, nothing Ayon said to Officer Williams prolonged the length of the
    investigation into the traffic infractions. It was Officer Burnett—not Officer Williams—
    9
    The trial court may have relied on the time length of the video from Officer
    Williams’s body camera, which shows he first spoke with Officer Diep at 10 minutes and
    30 seconds into the video. But Officer Williams did not start his body camera until two
    minutes and 15 seconds into the stop.
    14
    who was in charge of conducting the records check. After receiving the response to the
    records check, Officer Burnett spent much of the stop standing next to Officer Williams
    watching him question Ayon. Around 16 minutes into the stop, Officer Burnett began
    filling out a field identification card, but there was no testimony that this was part of the
    investigation into a traffic infraction. The videos show multiple other officers standing or
    walking around the area throughout the stop. Apart from Officer Vallejo’s initial contact
    with Ayon, there was no evidence any of these officers did anything to investigate the
    traffic infractions. In short, the police did not “diligently pursue[] a means of
    investigation reasonably designed to confirm or dispel their suspicions quickly.”
    (Russell, supra, 81 Cal.App.4th at p. 102.) (See Rodriguez, supra, 575 U.S. at p. 352
    [stop was unduly prolonged where narcotics dog alerted seven to eight minutes after
    completion of investigation for traffic infraction]; People v. McGaughran (1979) 
    25 Cal.3d 577
    , 587 [holding ten-minute delay unlawful where all that was reasonably
    necessary for a traffic violation was for police to examine defendant’s license and
    registration, explain the violation, and then issue either a citation or a warning].)
    The Attorney General argues that Officer Williams reasonably took time during
    the stop to investigate suspicions that Ayon was under the influence of a controlled
    substance. “An officer’s inquiries into matters unrelated to the justification for the traffic
    stop . . . do not convert the encounter into something other than a lawful seizure, so long
    as those inquiries do not measurably extend the duration of the stop.” (Arizona v.
    Johnson (2009) 
    555 U.S. 323
    , 333.)
    Officer Williams testified that he thought it was necessary to perform sobriety
    checks because he believed Ayon was under the influence of a narcotic, but an officer’s
    subjective intentions are irrelevant to the lawfulness of the search. (Whren v. United
    States (1996) 
    517 U.S. 806
    , 813 (Whren).) And considering the record objectively,
    including both the officer’s testimony and the bodycam videos, there is no substantial
    evidence to support Officer Williams’s claim that Ayon appeared to be under the
    15
    influence. The videos show that Ayon did not display any conduct demonstrating
    insobriety, such as slurred or irregular speech, an inability to walk or stand normally,
    confusion, or any other mental incapacity. His eyes did not flutter when the officer
    shined a light into them, and the results of any other tests the officer performed are absent
    from the record. Officer Williams ostensibly based his initial suspicions on Ayon’s
    nervousness, but the videos do not show Ayon acting any more nervously than a typical
    person in a traffic stop. As Officer Williams conceded on cross-examination, “Most
    people are nervous when they are pulled over by the police.”
    Furthermore, the trial court made no express finding of credibility regarding any
    aspect of the officer’s testimony on this point. The court ruled that the officer’s actions
    were “objectively reasonable” and that the time spent prior to the arrival of the narcotics
    dog was “objectively reasonable under the totality of the circumstances while the officers
    were pursuing what objectively were legitimate investigative pursuits.” But the
    reasonableness of the stop and whether the investigation was “legitimate” are legal
    determinations that we review de novo. (Glaser, 
    supra,
     11 Cal.4th at p. 362.) Arguably
    those rulings were based on implied findings of fact, but it is unclear precisely what
    factual findings are implied here. The trial court never made any factual findings as to
    whether Ayon exhibited signs of intoxication, for example, or whether the officers were
    diligently investigating the traffic violations throughout the period preceding the
    narcotics dog’s alert.
    But even assuming the sincerity of Officer Williams’s stated suspicions, when
    viewing the facts objectively, Officer Williams continued to prolong the stop unlawfully.
    After completing the field sobriety tests, Officer Williams continued to talk for several
    minutes, repeating things he had already said about police procedures and the reasons for
    the stop. He further touched on topics completely unrelated to the traffic infractions or
    suspected drug use. These topics included Officer Williams’s own youth and interactions
    with the police; the fact that he (Officer Williams) was harassed by the police himself in
    16
    the past for “riding my motorcycle all over the side of a mountain”; and how “some
    people just don’t like the police” because of the way they were raised. Notwithstanding
    his subjective intentions, none of this conduct was reasonably designed to address either
    the traffic infractions or the suspected drug use from an objective standpoint. Viewing
    Ayon’s conduct as recorded in the videos, we see no evidence that would establish
    reasonable suspicion or probable cause to believe he was under the influence of a
    controlled substance.
    Furthermore, the dog sniff itself prolonged the stop. “The critical question . . . is
    not whether the dog sniff occurs before or after the officer issues a ticket . . . but whether
    conducting the sniff ‘prolongs’—i.e., adds time to—‘the stop’ [citation.]” (Rodriguez,
    supra, 575 U.S. at p. 357.) The dog sniff here added six minutes to the length of the stop.
    During this period, Officer Williams talked to Ayon about numerous topics irrelevant to
    the car stop, including, among other things, Ayon’s place of work and business; where he
    went to high school; Ayon’s marital status and children; Officer Williams’s own wife and
    children; Officer Williams’s background as an auto mechanic; and the general nature of
    growing up in the San Jose area. Again, none of this conduct constituted a diligent
    investigation into the traffic infractions. Nor did this discussion pertain to any purported
    investigation of Ayon being under the influence of a controlled substance.
    C. Relevance of the Preexisting Drug Investigation
    A close examination of the record shows the traffic infractions were not the actual
    motivation for the initial stop. Indeed, as Officer Burnett himself openly admitted on the
    video, he never intended to issue a citation, and he conceded that was not the motivation
    for the stop. Officer Williams was assigned to the San Jose Police Department’s Metro
    Unit, which specializes in narcotics investigations. He was dressed in plainclothes just
    before the stop, and his vehicle was one of multiple law enforcement vehicles behind
    Ayon’s vehicle when it turned onto North San Pedro Street. The officers were
    communicating with each other by radio while following Ayon, and they initiated the
    17
    stop through those radio communications. Officer Diep, who handled the narcotics dog,
    had been told before the stop that his presence with the dog would be required. When
    defense counsel attempted to question Officer Williams about the circumstances that led
    to the stop, Officer Williams repeatedly invoked his right not to answer those questions
    under Evidence Code sections 1040 and 1042.10 It is apparent the police suspected prior
    to the stop that they would find drugs in Ayon’s car, but the record holds no evidence of
    how they knew this.
    During argument on the motion to suppress, defense counsel asserted the police
    were actually conducting a drug investigation. The prosecution below did not expressly
    deny this was a drug investigation but argued the officers’ subjective intent was
    irrelevant. The trial court never addressed the matter on the record, but by sustaining
    multiple prosecution objections on relevance grounds, the court implicitly supported the
    prosecution’s position. The Attorney General does not expressly deny the existence of a
    preexisting drug investigation but claims he “found no support for this assertion in the
    record on appeal.”
    As a general matter, pretextual traffic stops do not violate the Fourth Amendment.
    (Whren, supra, 
    517 U.S. 806
    .) Under Whren and its progeny, the police may use a minor
    traffic infraction as a justification for stopping a vehicle, even if the traffic infraction is
    10
    Evidence Code section 1040 sets forth a privilege to refuse to disclose official
    information if “[d]isclosure of the information is against the public interest because there
    is a necessity for preserving the confidentiality of the information that outweighs the
    necessity for disclosure in the interest of justice . . . .” (Evid. Code, § 1040, subd. (b)(2).)
    Evidence Code section 1042 provides in part, “if a claim of privilege under this article by
    the state or a public entity in this state is sustained in a criminal proceeding, the presiding
    officer shall make such order or finding of fact adverse to the public entity bringing the
    proceeding as is required by law upon any issue in the proceeding to which the privileged
    information is material.” (Evid. Code, § 1042, subd. (a).) The trial court made no
    express rulings on the officer’s invocations of the privilege, but the court ordered defense
    counsel to ask different questions, impliedly sustaining the witness’s claims of privilege.
    The trial court also sustained multiple objections by the prosecution on relevance
    grounds.
    18
    not the actual motivation from the stop. This doctrine follows from the general rule that
    an officer’s subjective intent is irrelevant. (Id. at pp. 813-814.)
    The existence of a preexisting drug investigation is nonetheless relevant here. In
    deciding whether a warrantless search or stop is objectively reasonable, we look to the
    “facts known to the officer.” (Adams v. Williams (1972) 
    407 U.S. 143
    , 146; People v.
    Troyer (2011) 
    51 Cal.4th 599
    , 605.) Officer Williams testified as a fact witness about
    what he observed during the stop, and in the videos he made numerous statements about
    what he was observing at the time. Both during the stop and in his testimony about it,
    Officer Williams repeatedly accused Ayon of acting in a “hostile,” “aggressive,”
    “confrontational,” and “strange” manner. Officer Williams blamed Ayon for prolonging
    the stop and claimed he suspected Ayon was using drugs based on this asserted behavior.
    Officer Williams testified that he ordered the narcotics dog after he became suspicious
    that Ayon was under the influence of something.
    But the video shows Officer Williams requested a narcotics dog before conducting
    any purported sobriety checks, and the dog handler admitted he had been informed his
    presence would be required before the stop had even occurred. And Ayon’s conduct as
    documented by the videos is at odds with Officer Williams’s testimony. Although Ayon
    questioned why the police would ask to search his car and handcuff him in a routine stop
    for a traffic infraction, he was cooperative at all times. He showed no signs of hostility or
    aggression. The Attorney General concedes this much.
    The fact of the preexisting drug investigation explains why Officer Williams
    prolonged the stop until the narcotics dog arrived. And, along with the video evidence,
    the fact of the preexisting drug investigation establishes that Officer Williams’s
    testimony about what he observed during the stop was neither reasonable nor credible,
    and thus did not constitute substantial evidence under the relevant legal standard. Were it
    not for the body camera videos, which undermine Officer Williams’s assertion that Ayon
    19
    appeared hostile or intoxicated, the outcome of this appeal likely would have been
    different.
    The trial court made no express findings about the credibility of Officer
    Williams’s testimony. The Attorney General argues that the court’s ruling includes
    implicit factual findings, but we cannot infer from the ruling exactly what factual findings
    it implies or how those findings might have relied on Officer Williams’s testimony. But
    here we have the benefit of the video evidence, which we can independently review.
    (See People v. Duff (2014) 
    58 Cal.4th 527
    , 551 [where interview of defendant was
    recorded, the facts of the confession are undisputed and reviewing court may apply
    independent review]; People v. Linton (2013) 
    56 Cal.4th 1146
    , 1177 [the facts of a
    confession are undisputed to the extent the interview is tape-recorded, making the issue
    subject to independent review]); In re Rosenkrantz (2002) 
    29 Cal.4th 616
    , 677 [because
    the trial court’s findings were based solely upon documentary evidence, reviewing court
    could independently review the record]). Even if the trial court’s ruling implies factual
    findings based on the credibility of Officer Williams’s testimony, the videos show any
    such findings are not supported by substantial evidence—i.e., evidence that is
    “reasonable, credible, and of solid value.” (Elder, supra, 11 Cal.App.5th at p. 130.)
    For the reasons above, we conclude the police failed to diligently pursue an
    investigation of the traffic infraction and instead unlawfully prolonged the stop. The
    Attorney General does not assert any other exceptions to the Fourth Amendment or that
    the error was harmless, and the record would not support such claims in any event.
    Accordingly, we will reverse the judgment.
    III. DISPOSITION
    The judgment is reversed, the conviction is vacated, and the matter is remanded.
    On remand, the trial court shall vacate its order denying Ayon’s motion to suppress the
    evidence seized in the car search and the court shall enter a new order granting that
    motion.

    People v. Ayon
    H047360
    Danner, J., concurring.
    For the reasons set out in Part II(B) of the majority opinion, I agree that the
    officers here unlawfully prolonged the traffic stop and therefore the trial court should
    have granted the motion to suppress. I write separately, however, to note my
    disagreement with certain aspects of the opinion’s analysis.
    Whether the officers in fact effected this traffic stop as part of a preexisting drug
    investigation is, I believe, on this record neither relevant nor necessary to concluding the
    search of the car occurred outside the “ ‘time reasonably required to complete [the stop’s]
    mission.’ ” (Rodriguez v. United States (2015) 
    575 U.S. 348
    , 357.) Evidence of such an
    investigation might have been relevant to assessing the credibility of Officer Williams’s
    version of the facts of the traffic stop. But the trial court sustained the prosecution’s
    objections to Ayon’s questions on this topic, and Ayon has not challenged those rulings
    on appeal.
    The majority opinion maintains “the traffic infractions were not the actual
    motivation for the initial stop” (maj. opn., ante, at p. 17) and “the fact of the preexisting
    drug investigation explains why Officer Williams prolonged the stop until the narcotics
    dog arrived.” (Id. at p. 19.) These assertions may well be correct, although they rest on
    scant evidentiary support in the record. More importantly, it is settled that the Fourth
    Amendment analysis may not turn on an inquiry into an officer’s motivation. “[T]he
    United States Supreme Court has made clear that an officer’s subjective intent plays no
    role in the Fourth Amendment inquiry. ‘An action is “reasonable” under the Fourth
    Amendment, regardless of the individual officer’s state of mind, “as long as the
    circumstances, viewed objectively, justify [the] action.” [Citation.] The officer’s
    subjective motivation is irrelevant.’ ([Brigham City v. Stuart (2006) 
    547 U.S. 398
    ,] 404,
    italics omitted; see also Whren v. United States (1996) 
    517 U.S. 806
    , 813.) . . . [J]ust as
    an officer’s venial motives will generally not undermine an otherwise valid search, a
    benign intent cannot save an invalid one.” (People v. Ovieda (2019) 
    7 Cal.5th 1034
    ,
    1052.)
    With these observations, I join the majority opinion.
