What happens after a crash in California

Most people involved in a crash have never been through the process before and have no idea what is supposed to happen next. Here is the ordinary sequence.

At the scene

CHP or the local police agency responds, checks for injuries, arranges medical transport and tow if needed, and clears the roadway. An officer collects driver, vehicle and insurance details and speaks to anyone who saw it. If the roadway is blocked, clearing traffic takes priority over paperwork.

The first hours

The incident exists only as dispatch data at this stage — the same data this site publishes. No report has been written yet.

Days 1 to 14

The investigating officer writes the collision report. In California this typically takes 7 to 14 days for a routine collision. Reports involving serious injury, a fatality, or a criminal investigation take considerably longer, and in a fatal case a full reconstruction can run for months.

Insurance, in parallel

Insurers do not wait for the report. Expect a call from the other driver's insurer well before the report exists — sometimes within a day. You are not obliged to give a recorded statement to another driver's insurance company.

When the report is ready

The report is filed under the incident number with the investigating agency and released to parties of interest. It contains the officer's diagram, statements, and an opinion about how the collision occurred. That opinion is not binding on anyone, but insurers weigh it heavily.

Deadlines run from the crash date, not the report date

This catches people out. Waiting for the report does not pause any legal deadline — see our guide on deadlines after a California crash.
