Question 4124

Are reaction distance and braking distance the same thing?

  1. Yes.
  2. Only in some cases.
  3. No.
Show answer and explanation

Correct answer: No.

No. Reaction distance runs from when you notice a hazard until you press the brake, and you aren't braking yet during that distance. Braking distance starts at that moment and ends when the vehicle stops. One follows the other, and together they make up the stopping distance.
