Speed and stoppingQuestion 27 of 235

You stop behind a vehicle in traffic. How much space do you leave in front of you?

  1. As little as you can, so no other vehicle can enter.
  2. None. Stay very close to the bumper ahead.
  3. Only enough to see the brake lights ahead.
  4. Enough to move into another lane without reversing.
Show answer

Correct answer: Enough to move into another lane without reversing.

Extra space lowers the risk of hitting the vehicle ahead if a vehicle hits you from behind. It also lets you drive around trouble.
