By law, if you are involved in a collision, ________.

In the event of a collision, it is legally required to stop at the scene of the accident. This law exists to ensure that all parties involved in the accident can exchange necessary information, assess injuries, and provide assistance if needed. Failing to stop could lead to serious legal consequences, including charges of hit and run, which can carry significant penalties. Stopping ensures that the situation can be handled appropriately and that the rights and responsibilities of all parties can be addressed.

While notifying the police and exchanging insurance information are also important steps to take after an accident, the primary legal obligation is to stop. Not stopping at the scene could lead to further legal complications, emphasizing the importance of this requirement.
