True or False: Engine braking is an effective method for controlling speed on downgrades.

Engine braking is indeed an effective method for controlling speed on downgrades. This technique utilizes the engine's compression to help reduce the vehicle's speed without relying solely on the brakes. When a driver downshifts to a lower gear while going downhill, the engine creates resistance, which slows the vehicle down. This is particularly important for larger vehicles, such as trucks and buses, where overheating brakes can lead to diminished stopping power and potential brake failure.

Using engine braking on downgrades helps maintain safer speeds, reduces wear on the brake components, and minimizes the risk of brake fade, which can occur when brakes are used continuously over long descents. It's a crucial skill for drivers operating heavy vehicles to manage their speed effectively and ensure safe operation on inclines and declines.
