Question 8135

On a downgrade, when does the vehicle brake better?

  1. It brakes the same with a load as without a load.
  2. It brakes better when it is carrying a load.
  3. It brakes better when it is not carrying a load.
Show answer and explanation

Correct answer: It brakes better when it is not carrying a load.

At the same speed, a vehicle with more mass has more energy and is harder to slow down. On a downhill grade, the slope also pushes it downhill, so it brakes better empty than loaded. If you are carrying a load, start braking earlier and use engine braking. In the image, a sign warns of a steep downhill grade.
