What to Do After a Car Accident

A practical, step-by-step checklist for the minutes, hours and days after a Southern California collision.

Reviewed Sep 17, 2026

After a collision, get to safety and check for injuries first, call 911 if anyone is hurt or the road is blocked, exchange information with the other driver, document the scene, and note the responding agency so you can locate the official report later. The steps below walk through each part.

At the scene: stay safe first

Your safety comes before anything else. If it is safe to do so, move out of live traffic and turn on your hazard lights.

  • Check yourself and passengers for injuries.
  • Call 911 if anyone is injured, or if vehicles are blocking traffic.
  • Move to a safe location off the roadway when possible; otherwise stay belted inside with hazards on.
  • Do not leave the scene — leaving a collision you were involved in can be a crime.

Exchange and collect information

Gather the details you will need for an insurance claim and to locate the report.

  • Names, phone numbers and driver-license numbers of everyone involved.
  • Vehicle make, model, color, and license-plate numbers.
  • Insurance company names and policy numbers.
  • Names and badge numbers of responding officers, and the agency they work for.

Document the scene

Photos and notes taken at the scene are hard to reconstruct later.

  • Photograph vehicle damage, the overall scene, road conditions and any traffic signs or signals.
  • Note the date, time, direction of travel and the nearest cross street or freeway exit.
  • Write down what happened while it is fresh.

Find the responding agency and the report

The agency that responds to the collision prepares the official report. Knowing which agency responded is the key to requesting it later.
