Before descending a steep hill, what is a good safe driving practice?

Before descending a steep hill, slowing down or gearing down is considered a good safe driving practice because it helps to maintain control of the vehicle and manage its speed on the descent. When a truck descends a hill, gravity can cause it to gain speed quickly, making it challenging to control. By reducing speed beforehand, the driver is better equipped to handle the descent safely and can use engine braking effectively.

Gearing down allows the engine to assist in slowing the vehicle, reducing the need to rely solely on the brakes, which can overheat and become less effective if used continuously over a long hill. This method not only enhances safety but also prolongs the lifespan of the braking system. Overall, preparing the vehicle for the descent by slowing down or gearing down is a proactive approach to managing the increased risks associated with driving downhill.
