Final answer:
Covering the brake involves keeping the foot hovering over the brake pedal for quicker reaction time, while riding the brake involves keeping constant pressure on the brake pedal even when it is not necessary.
Step-by-step explanation:
Covering the brake and riding the brake refer to two different driving techniques related to braking. When a driver covers the brake, it means that they keep their foot hovering over the brake pedal in anticipation of needing to brake suddenly. This allows for quicker reaction time in case of an emergency. On the other hand, riding the brake refers to the act of keeping constant pressure on the brake pedal, even when it is not necessary. This can lead to overheating of the brakes and excessive wear.
