Question 5530
What does stopping distance depend on?
- On speed, reaction time, and braking time.
- On speed only.
- On the type of vehicle only.
Show answer and explanation
Correct answer: On speed, reaction time, and braking time.
Stopping distance is the sum of two parts. Reaction distance depends on your reaction time and speed. Braking distance depends on speed and how well the vehicle brakes, which varies with the brakes, tires, load, or road conditions. That's why looking only at speed or the type of vehicle isn't enough. In the image, it's raining, and the wet surface increases braking distance.
