You are driving a truck with a manual transmission. What gear will you probably have to use to take a long, steep downhill grade?
Answer: C
A lower gear than you would use to climb the hill.
Remember to shift your gear down when you are on a downhill road. Ensure that you are in a lower than the gear you need to climb the same hill.
All choices
- AA higher gear than you would use to climb the hill.
- BThe same gear you would use to climb the hill.
- CA lower gear than you would use to climb the hill.
Why the other answers are wrong
A. A higher gear than you would use to climb the hill.
Choice A is wrong because a higher gear provides less engine braking on a downhill grade.
B. The same gear you would use to climb the hill.
Choice B is wrong because using the same gear as for climbing does not provide sufficient engine braking downhill.
