If your vehicle becomes disabled on a 400-series highway, you should…?

  1. Blow your horn for help
  2. Get out and walk to get help
  3. Get out and try to wave highway traffic around your vehicle
  4. Pull over, activate your emergency flashers and wait for help ✓

Answer: D. Pull over, activate your emergency flashers and wait for help

Pull over to the nearest shoulder, turn on your emergency flashers and wait for help inside your vehicle.

Why this is the answer

The handbook's freeway trouble section says to act at the first sign of trouble: check your mirrors, put on your hazard lights, ease off the gas and get to the nearest shoulder. It warns never to stop in the driving lanes. While you wait for help, stay in your vehicle with the doors locked; if someone stops, ask them to call the police or an automobile club, and use a cellphone yourself if you have one. That matches pulling over, using flashers and waiting rather than standing outside.

Why the other answers are wrong

Remember it

When your car quits on a fast highway, your job is to get off the lanes and be a patient passenger, not a traffic director.
