Never drive away from the scene of an accident, not even a minor one, PROTECT THE SCENE. A few years ago, Denise Schipani, 54, and her son were stopped at a traffic light near their home in Huntington Station, New York, when a car hit theirs from behind. Exit the vehicle if you can and turn on the emergency flashers. If there is significant property damage, bodily injury or death, you should call the police.
Ask for a police report to be filed in situations where police arrive at the scene and obtain the names and badge numbers of the responding officers. After the car accident, immediately determine if someone was injured. If so, call 911 for an ambulance and police to arrive at the scene. Even if the incident was minor and everyone is cooperating, consider calling the police.
That way, you'll have an official report to hand over to your insurance company.
