On a descent with a manual transmission, why should you use a lower gear than you used going uphill?

• A. To provide engine braking and maintain control.
• B. To accelerate more quickly.
• C. To save fuel.
• D. To prevent gear grinding.

Answer: (A)

Using a lower gear on a descent lets the engine do part of the braking for you. When you downshift, the engine’s resistance adds braking force, which slows the vehicle and helps you stay in control without riding the brakes. This keeps brake heat down and reduces the chance of losing braking power on long or steep slopes. Downshift gradually and keep the engine within a safe RPM range so you don’t jerk the car or over-rev. The primary aim here is controlled deceleration, not accelerating or saving fuel.
