Answer:
If you can do so safely, collect the other driver’s contact and insurance information, photographs or video, witness details, vehicle information, and the police report number, then seek medical care.
Your health and safety come first. Call 911 when appropriate and, if your condition allows, exchange names, contact information, driver’s-license details, license-plate numbers, and insurance information with the other driver. Photograph the vehicles, road, traffic controls, weather, visible injuries, and any debris or skid marks.
Ask witnesses for their contact information and note the responding agency and report number. Avoid moving vehicles unless safety or law enforcement requires it, and seek medical attention promptly. A New Hampshire car accident lawyer can use this information to investigate and preserve the claim.
