What California law says after a truck accident

Why commercial vehicle cases are different

A collision involving a commercial truck or bus is not simply a larger car collision. Commercial carriers operate under federal and state safety regulations covering driver hours of service, vehicle inspection and maintenance, driver qualification, and cargo securement. A violation of those rules can bear directly on how the collision happened.

These cases also involve records that do not exist in an ordinary collision: electronic logging device data, engine control module data, maintenance and inspection files, driver qualification files, dispatch records, and in many vehicles onboard camera footage. Federal rules require carriers to keep much of this material only for a limited time. Driver vehicle inspection reports must be retained for three months, records of duty status and the supporting documents behind them for six months, and annual inspection reports for fourteen months. The logging device on the truck itself typically holds only the current day and the previous seven days.

Other material that often matters most, including engine control module data, onboard camera video, and raw location data, carries no federal retention period at all and is overwritten on the carrier’s own cycle.

For that reason, requests to preserve evidence are often sent to the carrier and its insurer early. Responsibility may also extend beyond the driver to the motor carrier, a maintenance contractor, or whoever loaded the cargo.

Reporting requirements after a California collision

California imposes reporting duties on drivers that are separate from any insurance claim.

A report must be filed with the DMV on form SR-1 within ten days of a collision that caused any injury, any death, or more than one thousand dollars in property damage to any one person. This duty applies regardless of fault, applies even when police responded and wrote their own report, and is not satisfied by notifying an insurance company. With current repair costs, most collisions that involve a body shop meet the damage threshold.

A separate rule covers collisions causing injury or death. The driver must make a written report to the California Highway Patrol, or to the city police department where the collision happened in a city, within twenty four hours. The statute states this duty for every injury or fatal collision. In practice, where officers responded and completed a report at the scene, that report generally satisfies the agency’s need, but a driver who assumes this without confirming it is relying on practice rather than on the text of the law.

Missing the DMV deadline can lead to suspension of driving privileges, an outcome unrelated to who caused the collision.
