What should you do when driving down a long steep hill?

When driving down a long steep hill, the correct strategy involves managing your speed and the braking system efficiently to maintain control of the vehicle. The effective approach is to release the brake when you are 5 mph below your safe speed, allowing you to control your descent without overheating the brakes.

This involves using the appropriate gear for the downhill section, which helps to naturally slow the vehicle via engine braking. By releasing the brake at 5 mph below the safe speed, you give yourself a cushion to react to any changes in the road or traffic conditions, ensuring that you're not constantly applying pressure to the brakes, which can lead to overheating and brake fade.

This technique strikes a balance between using the engine to assist in slowing the vehicle while also being aware of your speed, as it's crucial to stay below the safe limit for safe handling. Regularly using the brakes without allowing them to cool can lead to diminished braking performance, making it essential to apply the brakes intelligently rather than relying solely on them throughout the descent.
