At the scene
Move to safety when possible, call emergency services when appropriate, and exchange the information required at the scene. Photograph the vehicles, road, signals, weather, debris, and visible injuries without interfering with responders.
After leaving the scene
Keep the report number, towing information, repair communications, medical instructions, and witness details together. Write a factual chronology while events are fresh and do not edit original photographs or messages.
Insurance communications
Report the event as required by the applicable policy, keep a call log, and ask what any requested authorization or recorded statement covers before agreeing. Different policies and state systems can change the path.
Questions for an Injury Law Firm
Ask which policies may apply, which evidence should be preserved, whether another party controls video or vehicle data, which deadline needs current state-law review, and who would manage the matter.
