Total stopping distance is made up of which three parts?
- A.Reaction distance, engine braking distance, and brake lag distance
- B.Perception distance, following distance, and braking distance
- C.Skid distance, reaction distance, and rollover distance
- D.Perception distance, reaction distance, and braking distance
Correct answer
D. Perception distance, reaction distance, and braking distance
Why
Stopping distance combines the ground you cover while perceiving a hazard, the ground covered while reacting and moving to the brake, and the distance the brakes need to stop the vehicle. Each part grows with speed, which is why total distance climbs so fast.
