Missing footage does not decide your DUI case by itself. If a recording exists anywhere in the police file, the prosecutor has to turn it over. If it was never made or was destroyed, whether that helps you depends on how clearly useful it would have been and why it is gone.

What the prosecutor has to disclose

Under Penal Code section 1054.1, the prosecutor must disclose all relevant real evidence obtained in the investigation and “any exculpatory evidence,” if the prosecutor has it or knows the investigating agency has it. A recording of your stop is real evidence from the investigation, and if it helps you, it is exculpatory evidence as well. If the recording still exists, that duty covers the recording itself, not just an officer’s description of what it shows.

Before asking a court to step in, counsel must make an informal request for the recording. Under Penal Code section 1054.5, if the prosecution fails to provide it within 15 days, counsel can ask the court to enforce disclosure, and the court can order immediate disclosure, grant a continuance, or tell the jury about a failure to disclose or a late disclosure. The same statute bars dismissing a charge for a discovery violation unless the U.S. Constitution requires it, so a discovery problem becomes an argument within the case rather than an automatic exit from it.

How long the recording is supposed to exist

For body-worn camera video, Penal Code section 832.18 lists practices that agencies must consider when setting their own retention policies; it does not ensure that any particular recording survives. It recommends keeping ordinary footage for at least 60 days, footage of an incident that leads to a detention or arrest for at least two years, and footage holding evidence that may be relevant to a criminal prosecution for as long as other evidence in that prosecution must be kept.

That statute covers body-worn cameras only. For in-car video kept by a city or county department, separate statutes let the department destroy routine video recordings, a category that expressly includes in-car video, after one year and only with approval from the city council or board of supervisors and the agency attorney’s written consent; recordings that are evidence in a filed claim or pending litigation must be kept until the litigation is resolved (Government Code section 34090.6 for cities; Government Code section 26202.6 for counties). Those two statutes apply to city and county departments, not to state agencies such as the California Highway Patrol. None of these rules promises that your stop was recorded or that the video still exists, which is why an early written preservation request matters.

If the recording is genuinely gone

Two different due process standards can apply, depending on how clearly useful the missing recording would have been.

California v. Trombetta (1984) held that due process requires preserving evidence only when its exculpatory value was apparent before it was destroyed, and only when the defense could not obtain comparable evidence by other reasonably available means. Arizona v. Youngblood (1988) addressed evidence that was only potentially useful rather than obviously favorable: losing that kind of evidence violates due process only if the defense can show bad faith by police, not mere carelessness.

In practice, the question is what the recording would have shown. If the officer’s report describes something specific the video would have confirmed or contradicted, such as a claimed lane violation or an instruction given during a field sobriety test, that gives counsel a concrete point to develop when the video is gone.

What to do now

  • Have counsel send a written preservation request and, if needed, a formal discovery demand promptly rather than waiting.
  • Ask counsel to find out whether a dashcam, a body camera, or a nearby traffic or city camera captured the stop; a separate camera system keeps footage on its own schedule, so a prompt records request matters.
  • Compare the written report’s stated time and location against any other timestamped evidence you have. A mismatch there is worth raising with counsel even apart from the video question.
  • Move quickly. The retention rules above set minimums and conditions; they do not mean a particular recording still exists.

If your stop should have been recorded and the footage cannot be found, an attorney who works on illegal traffic stop challenges can request what exists, and that same video, or its absence, can become part of cross-examining the officer at trial if the case reaches that stage, alongside the other steps that happen early in the DUI process.
