8 . If a trailer is too high:
Coupling will be easier.
Before coupling together a tractor and a trailer, you should make sure the trailer is at the proper height. If the trailer is too low, the trailer nose may be damaged. If the trailer is too high, it may not be able to couple correctly.
9 . In a combination rig, it is best to make:
Slow, planned stops.
When driving a combination vehicle, it is important to brake well in advance and look far ahead of your vehicle to avoid the need for sudden stops. Making habits of these actions will help you prevent your trailer from jackknifing.
10 . A shut-off valve:
Should always be open.
Shut-off valves are used in air supply lines to control the passage of air from one trailer to another. The rear shut-off valve should always be closed to prevent air from leaving the braking system.
11 . One way to prevent a rollover is to:
Keep cargo as far from the ground as possible.
A rollover is more likely if cargo is unevenly loaded in a rig. To help prevent a dangerous rollover, it is important to keep a load as centered on the rig as possible.
12 . ____ are the cause of more than half of all accident-related truck driver deaths.
Pedestrians
More than half of all accident-related truck driver deaths are a result of truck rollovers. To help prevent a rollover, be sure to load cargo low to the ground and centered on your rig. Take corners slowly and carefully.
13 . Test the tractor protection valve by:
Releasing air with the gas pedal.
You should test the tractor protection valve by allowing the air supply to properly charge, turning off the engine, then releasing air from the system by pressing the brake pedal several times. The tractor protection valve should move into its emergency position when psi drops to an unsafe level.
14 . Failure to keep the fifth wheel plate properly greased could:
Affect the lights.
Failure to keep the fifth wheel plate properly lubricated can create friction between the tractor and trailer, causing steering problems.
