Using Traffic Camera Footage as Evidence After a Car Accident

There were 39,254 deaths due to motor vehicle traffic accidents in the US during 2024, based on statistics provided in April 2026. The National Highway Traffic Safety Administration (NHTSA) projected 36,640 deaths from traffic accidents in 2025, representing a 6.7% decline compared to 2024.

A recording of the car crash made by a traffic camera could serve as important evidence about the cause of the accident and the movement of cars involved in the crash, as well as the road conditions at the moment of the collision.

The usefulness of the recording depends on its quality and the location of the traffic camera. It should be noted that not all roadways have traffic cameras, and not all of them record video for a long period of time.

Knowing how to locate and preserve relevant footage can help accident victims protect important evidence.

There are ways on how to obtain traffic camera footage that can establish fault after a car accident. The same way there are limitations that may affect its use as evidence. Here’s what you need to know.

The Cameras on the Freeway Are Not Evidence

The Department of Transportation installs cameras for traffic management. This is stated by Caltrans, which explains clearly the reason behind the installation, which is confirming the report and sending the right kind of response.

There are some districts that release images periodically in place of videos, meaning that even preserving a video stream is not possible in this case.

So the first honest answer in many cases is that nothing exists to request. That is not an agency declining to cooperate. It is an architecture decision somebody made when the system went in, and no records request reaches a recording that was never created.

The Cameras That Do Retain Something

Enforcement cameras are a different category entirely. Red light and speed systems operated by or for a municipality capture and store images because storage is the entire point of them.

The recordings of transit vehicles, school buses, and toll facilities have separate records according to their own schedule. Each of these is handled by a separate custodian following separate protocols, but it is crucial to know the owner of the recording rather than the law behind it.

Private cameras usually turn out to be the productive source. The gas station on the corner, the storefront across the intersection, an apartment lobby angled toward the street, a parking structure, a transit bus, a rideshare dashcam, and another driver’s dashcam. Retention on those systems is often measured in days, and nobody at the business is thinking about a collision that happened outside.

Companies that handle these files will consider the canvass process as a component of the intake phase as opposed to an activity that comes after accepting the case.

An Orange County car accident lawyer can help gather and preserve important evidence, including physical evidence, video footage, witness statements, and police reports, to support an injury claim.

Preservation Is the Part With a Clock

Two different instruments do two different jobs here. A public records request goes to a government custodian and runs on a statutory timeline that varies by state. It reaches whatever still exists on the day it lands, and agencies may charge fees for copies and media, with staff-time charges varying by state.

A preservation letter goes to a private business and asks it to hold a specific window of recording before the system overwrites it. A business that is not a party to the case is usually not legally required to honor the letter, so it works best as a fast, polite request. That letter usually goes out first, because private retention is shorter than any records timeline.

A convenience store running a seven-day loop will have overwritten the relevant footage before a records request to a police department has even been acknowledged.

What Footage Proves and What It Does Not

A video shot by a stationary camera rarely reveals what viewers are hoping for. This is due to the fact that elements such as angle, distance, frame rate, and compression, amongst others, always work against the viewer, while speed cannot be determined through it unless the scene has been reconstructed.

Thirty frames per second from two hundred feet will capture about sixty frames from a two-second sequence.

What it does establish reliably is sequence. Which vehicle entered the intersection first? What the signal was showing. Where each car sat a moment before impact.

Those are often the disputed facts, hence why video evidence that may look insignificant on-screen can settle a liability case that would have required two experts for a whole week otherwise.

The practical order runs backward from what people assume. Identify who owned the view before asking whether anyone has a right to it, and start with the businesses rather than with the agencies, because the businesses are the ones whose recordings disappear first.
