When stopping behind a vehicle, you should:

Stay well behind the vehicle in front of you, even if you are both stopped. The vehicle could back up unexpectedly, or you may need space to get out of the way of another vehicle bearing down on you from behind.

• Stop far behind the vehicle, then slowly creep up.
• Stay well behind the vehicle.
• Make a quick stop right behind the vehicle.
• Stay about four car lengths behind the vehicle.
