As preparation in the event that they are involved in a car accident, a parent should tell their teenage child to call 911. If they have been in an accident or injured, they should have all their emergency contacts, such as their parents’ numbers, in the glove box. They should gather information from the other party, including name, address, phone number, and insurance information.  Additionally, they should gather witnesses’ names and contact information.  They should also take pictures of the scene and the automobiles involved.
