What is the recommended procedure for braking on a downgrade?

• A. Speed up to clear the downgrade.
• B. Coast in neutral and let engine brake.
• C. Downshift to higher gear and brake hard.
• D. Descend slowly, use lower gear to control speed, and apply service brakes judiciously to avoid overheating.

Answer: (D)

When you’re descending, the goal is to control the speed without overheating the brakes. Do this by staying in a lower gear to use engine braking and by applying the service brakes in controlled, gradual bursts as needed. Descend slowly so you have time to react to curves and traffic, and let the engine help you slow the vehicle rather than relying solely on the brakes. Coasting in neutral removes engine braking and makes you depend entirely on the brakes, which can overheat and fade on a long downgrade. Downshifting to a higher gear and braking hard defeats the purpose of engine braking and can throw you off balance or cause loss of control. Trying to speed up to clear the downgrade is dangerous because you’d be limiting your ability to stop safely if something changes ahead. So, the safest approach is a careful, slow descent in a lower gear with judicious braking to keep speed under control and prevent brake overheating.
