When driving downhill, you should do which of the following?

When driving downhill, it is essential to downshift to a lower gear than you used while going uphill. This action helps maintain a safe speed without relying excessively on the brakes, which can lead to overheating and reduced braking effectiveness. By using engine braking through downshifting, you enhance control over the vehicle's speed and reduce the risk of brake failure.

The technique of downshifting engages the engine’s resistance to help slow the vehicle down, which is particularly important on steep descents where gravity can significantly increase speed. It is a crucial skill for maintaining control of a heavy vehicle, such as those driven under a CDL Class A license, ensuring safety for the driver and others on the road.

This approach not only conserves brake performance but also minimizes the likelihood of long-term brake damage from overheating. It is essential to remember that engine braking works best with lower gears, making downshifting a vital practice when going downhill.
