1. Always stop if you are involved in an accident, this is your legal obligation. Even if you do not think there was any damage, any time you collide with something, you need to stop your car. 2. Never admit responsibility for the accident.

Your legal contract with your car insurance company clearly states that you must not assume responsibility or liability under these circumstances.
