The information you are required to exchange with the other driver, or provide to a witness to the accident or a police officer if the other driver is unable to accept the information due to injury, includes:
Your name and contact information;
The make and model of your vehicle;
The name of your insurance provider and your policy number; and
Your driver’s license number.
Some states require you to display your insurance card and registration to the other driver, and the police officer investigating the accident will certainly want to see that information as part of the accident report.
