📚Alabama General Knowledge — Question 7 of 10

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.
