Choosing and maintaining a proper speed is the most important objective when driving down a steep grade. This is crucial for several reasons. When traveling downhill, gravity increases the speed of your vehicle, which can make it difficult to control if you do not adjust your speed appropriately.

Maintaining a safe speed helps prevent the risk of overheating brakes from excessive use, as drivers may rely heavily on them to control momentum. Additionally, a proper speed allows for better handling and increased reaction time in case of sudden obstacles or changes in traffic conditions.

Other factors like listening to the sound of the engine, turning on hazard lights, or using the horn may have their places in specific situations, but they do not directly address the critical need for managing speed safely and effectively on steep grades.
