Question

On a long downgrade, you should choose...?

a. The same gear you would use going up it
b. A lower gear that you would use going up it
c. A higher gear than you would use going up it
d. Any of these depending on the weather conditions

Answer 1

On a long downgrade, the correct gear choice is typically the same gear you would use for going up, as it allows for engine braking to control speed.

Step-by-step explanation:

On a long downgrade, the appropriate gear to choose is generally 'a. The same gear you would use going up it.' Using the same gear helps to maintain control of the vehicle by using engine braking to assist in reducing speed. This technique is especially important for large vehicles, such as trucks, as it prevents the brakes from overheating and losing effectiveness. It's crucial to remember that while other factors like weather conditions can influence driving method and vehicle handling, the primary mechanism for controlling speed on a downgrade should be relying on the correct gear selection.
