After ensuring everyone’s safety and calling 911 if needed, you should: (1) exchange insurance and contact information with all parties involved, (2) document the scene with photos of vehicles, injuries, and road conditions, (3) obtain contact information from witnesses, (4) notify your insurance company about the accident, (5) seek medical attention even if you feel fine, as some injuries may not be immediately apparent, and (6) contact an experienced car accident attorney to protect your rights. Avoid admitting fault or making statements about the accident to other insurance companies without legal guidance.
