What to do at a traffic stop or after a crash

Short answer

At a traffic stop, signal, pull completely onto the right shoulder, stay in the car with your hands where the officer can see them, and follow instructions. After a crash, stop, check for injuries, call 911 if anyone is hurt, move out of traffic if you can, and exchange information.

Knowing the steps ahead of time helps you stay calm when your heart is racing.

When police signal you to stop

Turn on your signal to show you see the officer.
Pull completely onto the right shoulder, in a well-lit spot if you can.
Turn off the radio, lower your window and stay in the car unless told to get out.

After a crash

Check for injuries and call 911 if anyone is hurt.
If no one is hurt and the cars can move, move them out of traffic and turn on your hazard lights.
Exchange names, license numbers, registration and insurance information.
Report the crash to police or your state DMV when required.
