What is a good safe-driving practice when descending a steep hill?

When descending a steep hill, a good safe-driving practice is to gear down and use the motor to assist in braking. This involves shifting to a lower gear, which allows the engine to help slow the vehicle down through engine braking. This technique reduces reliance on the brakes alone, helping to prevent brake overheating and fading, which can occur during prolonged periods of braking on a decline.

By engaging a lower gear, the driver maintains better control of the vehicle’s speed and minimizes the risk of losing control due to excessive speed. This practice is particularly vital on steep grades where the potential for the vehicle to accelerate uncontrollably is higher.

In contrast, coasting with the clutch disengaged or shifting into neutral eliminates any engine resistance and can lead to increased speeds, making it more difficult for the driver to control the vehicle. Turning off the ignition while descending a hill is hazardous, as it would disable power steering and power brakes, significantly impairing the driver's ability to steer and stop effectively.
