What is a good safe driving practice before descending a steep hill?

Before descending a steep hill, the recommended safe driving practice is to slow down or gear down. This method is crucial because it helps to maintain control of the vehicle during the descent. By slowing down before reaching the hill, you reduce the risk of gaining excessive speed, which can lead to dangerous situations such as loss of control or overheating brakes due to excessive friction.

Gearing down, or shifting into a lower gear, allows the engine to assist in slowing the vehicle down through engine braking. This reduces reliance on the brake system, which can overheat and fail if used continuously on a long or steep decline. Proper gear selection also enhances traction and stability, making it easier to navigate the descent safely.

Using these techniques not only promotes safety but also ensures the longevity of brake components by minimizing wear and tear.
