The use of brakes on a long, steep downgrade is only a supplement to the braking effect of the engine. True or False?

The statement is true because when driving on a long, steep downgrade, the primary braking force should come from the engine rather than solely relying on the vehicle's brakes. This is achieved through "engine braking," which involves shifting into a lower gear to allow the engine to help control the speed of the vehicle. The use of the brakes, in this case, serves as a supplemental measure to assist with speed regulation, particularly if the vehicle begins to gain too much speed despite engine braking. Relying entirely on brakes for long descents can lead to brake overheating or failure. Therefore, the statement accurately reflects safe driving practices when navigating downgrades.
