What is the primary benefit of using engine braking when descending hills?

Using engine braking when descending hills primarily helps maintain a safe speed. When you rely on engine braking, the vehicle’s engine creates resistance by allowing the vehicle to slow down as it goes down a slope. This is crucial because it reduces the reliance on the braking system, which can overheat and become less effective if used continuously on steep descents.

Maintaining a safe speed while going downhill is essential for vehicle control and safety. By controlling the vehicle's descent speed through engine braking, you minimize the risk of losing traction or control, which can lead to accidents. This technique is particularly important in military driving, where safety and stability are paramount during operations.

While other benefits such as reduced wear on the brakes and potential fuel savings may occur, the foremost reason for utilizing engine braking is to ensure that you can navigate hills safely and effectively without exceeding safe speed limits.
