What should a driver do when coming down a hill?

When coming down a hill, using a low gear is the appropriate action for a driver to take. This technique helps to control the vehicle's speed without relying excessively on the brakes. By shifting to a lower gear, the engine braking effect is increased, reducing dependence on the brake system and thus helping to prevent brake overheating. This is particularly crucial on steep descents, where the potential for loss of control can be higher.

It's important to manage speed carefully when navigating hills, as the natural tendency is to gain speed due to gravity. Utilizing low gear allows the driver to maintain better control and reduces the risk of skidding or losing traction, which is especially vital in adverse weather conditions or on poorly maintained roads. Proper gear selection is a fundamental aspect of safe driving during such situations, contributing to overall road safety.
