Which is a proper technique when going down a steep hill?

Answer: B — Maintain steady speed

Maintaining a steady speed while going down a steep hill is crucial for safe driving, especially in large vehicles that require careful handling due to their weight. When you maintain a steady speed, you control the vehicle’s momentum and minimize the risk of losing control. This technique helps in avoiding the overheating of brakes, which can occur if they are applied constantly, and it reduces wear and tear on brake components. By using engine braking, which often involves downshifting to a lower gear when going downhill, you can effectively manage your speed without relying excessively on the brakes. This method takes advantage of the engine’s power to slow down the vehicle, providing a safer descent while being more efficient for the truck. Coasting in neutral is dangerous because it reduces your control over the vehicle. Using the brakes constantly can lead to brake failure due to overheating. Shifting to a higher gear when heading downhill can also lead to increased speed and loss of control. Thus, maintaining a steady speed, utilizing the proper gear for engine braking, is the best and safest technique when descending steep hills.
