Question

After hooking up, you should check the fifth wheel connection by:

A) Driving away at 20 mph and pulling down the trailer hand valve
B) Pulling the tractor ahead sharply to release the trailer brakes
C) Pulling the tractor ahead gently with the trailer brakes locked

Answer 1

After hooking up, you should check the fifth wheel connection by pulling the tractor ahead gently with the trailer brakes locked.

Step-by-step explanation:

After hooking up, you should check the fifth wheel connection by pulling the tractor ahead gently with the trailer brakes locked. This allows you to ensure that the fifth wheel and trailer are properly connected before driving. By pulling the tractor gently with the trailer brakes locked, you can check if the connection is secure and if the trailer moves smoothly with the tractor.

Pulling the tractor ahead sharply to release the trailer brakes (option B) is not recommended as it can cause damage to the fifth wheel connection and trailer. Driving away at 20 mph and pulling down the trailer hand valve (option A) is also not a recommended method for checking the fifth wheel connection as it can put unnecessary stress on the connection.
