On a long downgrade, which gear should you choose?

When driving on a long downgrade, it is important to use a lower gear than the one used for ascending the hill. Choosing a lower gear helps in controlling the vehicle's speed more effectively as gravity pulls it downward. This practice leverages engine braking, which assists in maintaining a safe and manageable speed without relying heavily on the brakes alone. Using a higher gear or the same gear as when going uphill could lead to an increased speed that may become difficult to control, raising the risk of losing braking efficiency or experiencing brake fade from excessive use. Always selecting an appropriate gear for the descent enhances safety and helps prevent potential accidents.
