What should I do immediately after a car accident?
Direct answer
Check yourself and others for injuries and call 911 if anyone is hurt or the roadway is blocked. If the vehicles can be moved safely, clear the travel lanes and turn on hazard lights to prevent a secondary collision. Safety comes before everything else, including documentation.
More detail
The first moments set the tone for both your health and any claim. Once immediate safety is addressed, seek medical evaluation even if you feel fine, because some serious injuries are not immediately obvious. Then photograph the scene, exchange information, and collect witness contacts while people are still present.
