First steps in the immediate aftermath of an accident:
Call your insurance agent to best advise for the situation.
Take pictures of the property damage and the accident scene. When in doubt, take a picture.
Name, address, phone number, and driver’s license number of the driver of the other vehicle. Also good to have is the insurance company, insurance agent (name and phone number), and policy number of the other vehicle’s driver.
Get a copy of the police report (if one was filed).
Get the medical treatment you need, as soon as possible.
