Road signsQuestion 62 of 296

Why should you leave extra space behind the vehicle ahead in a work zone?

  1. A fast car behind may push you into the car ahead
  2. The law says to stay 100 m behind in a work zone
  3. Cones can fall onto the road in front of you
  4. Your brakes work less well in a work zone
Show answer

Correct answer: A fast car behind may push you into the car ahead

More space gives you room if you are hit from behind. It also gives you time to react to sudden stops.
