What is a safe practice when encountering a steep decline while driving?

Using engine braking when encountering a steep decline is a safe practice as it helps maintain control of the vehicle and prevents overheating of the brakes. Engine braking involves downshifting to lower gears, which allows the engine to slow the vehicle down through resistance, rather than relying solely on the brake system. This technique reduces the risk of brake failure that can occur due to prolonged use on steep declines.

Maintaining control of speed on a decline is crucial for safety, as excessive speed can lead to lost control of the vehicle, making it harder to navigate turns and respond to obstacles. Engine braking is particularly effective in heavy vehicles where the weight can significantly increase stopping distances if only the brakes are used.

Other methods, such as accelerating to maintain speed or engaging cruise control, could lead to an increase in speed, which is dangerous on steep declines. Shifting into neutral is also not advisable since it disengages the engine from the wheels, removing any engine braking effect, and increases the risk of losing control.
