Interior and exterior camera footage
Separately request footage from all interior cameras on the vehicle and all exterior cameras, since a demand for a single camera can leave the rest to cycle out.
MTA Video Preservation California: Why the First 48 Hours Decide the Case
MTA video preservation California litigation holds are, in practical terms, the single most time-sensitive task in any bus collision case. Transit agencies operate large fleets of vehicles equipped with interior and exterior surveillance systems, but the retention windows for that footage are short, often measured in days rather than months. An attorney who waits until after intake paperwork is signed to send a preservation letter risks losing the case's best evidence before the file is even open.

Why MTA Video Preservation California Runs on a Short Clock
Bus surveillance systems record continuously and overwrite older footage on a rolling cycle to manage storage capacity across a large fleet. Depending on the agency and the specific vehicle's recording system, that cycle can run anywhere from a matter of days to a few weeks. Unlike a private company that might retain footage indefinitely absent a reason to delete it, a transit agency's default behavior is destructive: footage disappears unless someone affirmatively intervenes to preserve it. By the time a typical personal injury intake process runs its course, client interview, records gathering, and initial case evaluation, the footage that would have shown exactly what happened may already be gone. Effective practice treats the preservation demand as a same-day task, not a step that waits for the rest of the file to be built.
What an Effective Preservation Demand Must Cover
A preservation letter limited to "the accident video" is not enough. Each data source can have its own retention schedule and its own custodian within a large transit agency, and a narrow request risks the agency preserving only the category explicitly named while other relevant data continues to cycle out. The demand should also identify the specific date, time window, route number, and vehicle identifier where known, since transit agencies operate hundreds of vehicles and imprecise identification can delay the search long enough for footage to be lost even after a preservation letter is received. A written demand also puts the agency on notice of a claim. California courts recognize that a party's destruction of evidence after receiving notice of a potential claim can support an adverse inference against that party, and can, in appropriate circumstances, support independent tort or discovery sanction remedies.
What the Demand Must Identify
GPS, telematics, and event data
Identify and request GPS and telematics data plus engine control module and event-data-recorder downloads, each of which can carry its own short retention schedule.
Driver logs, dispatch, and incident reports
Request driver logs and dispatch records and any incident or complaint reports generated internally as a result of the collision, so the paper record is preserved alongside the video.
Practical Checklist for Counsel
A diligent, documented preservation record is what makes spoliation remedies available later if the agency fails to act.

How quickly should an MTA video preservation California demand be sent?
Within 24 to 48 hours of being retained on a bus collision case, because transit agency video retention cycles can run as short as a matter of days before footage is automatically overwritten.
What categories of evidence should a preservation demand cover beyond the accident video?
An effective demand should separately identify interior and exterior camera footage, GPS and telematics data, event-data-recorder downloads, driver logs, dispatch records, and any internally generated incident reports, since each category can have a different retention schedule.
What happens if a transit agency destroys video after receiving a preservation demand?
California courts recognize that destruction of evidence after notice of a claim can support an adverse inference against the destroying party and, in appropriate circumstances, additional remedies, which is why a clear written demand matters even before litigation formally begins.
