Following a car accident, it is important to collect as much evidence as possible in order to protect your legal rights. The most useful evidence that you can gather includes photos of the damages sustained by your vehicle, photos and contact information of any witnesses who saw the accident occur, police reports filed at the scene of the accident (if an officer was present), medical records describing any injuries you or passengers in your vehicle sustained due to the accidents, and statements from both yourself and any other drivers involved in the crash.
