1 . How much space should be between the upper and lower fifth wheel?

About five inches of space

A maximum of two inches of space

No space

Before a trip, be sure to inspect all couplings. There should be no space between the upper and lower fifth wheel.

2 . Trailers with low underneath clearance can present challenges when driving over:

Bridges.

Railroad tracks.

Overpasses.

Railroad-highway crossings may be difficult to cross when pulling a trailer with a low underneath clearance. In particular, both low-slung units and single-axle tractors pulling long trailers are especially challenging to drive over raised crossings.

3 . When coupling a trailer:

Make sure to couple the proper glad hands.

Glad hands can be connected to any other glad hands.

Only one set of glad hands should be connected.

When coupling, make sure you couple matching glad hands. They are often color-coded to help drivers avoid mistakes. Typically, blue is used for service lines and red is used for emergency lines.

4 . What is the tractor protection valve?

A valve that keeps air in the brake system should a bad leak occur

A valve that prevents the trailer from being accidentally released

A valve that prevents the vehicle from going too fast

A tractor protection valve keeps air in a tractor or truck air brake system should the trailer break away or develop a bad leak. The valve will close automatically if the pressure drops to an unsafe level.

5 . Failure to keep the fifth wheel plate properly greased could:

Cause the trailer to disconnect.

Cause steering problems.

Cause braking problems.

Affect the lights.

Failure to keep the fifth wheel plate properly lubricated can create friction between the tractor and trailer, causing steering problems.

6 . One way to prevent a rollover is to:

Move cargo to the left side of the rig.

Keep cargo centered on the rig.

Move cargo to the right side of the rig.

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.

7 . What happens when the wheels of a trailer lock up?

The trailer will usually continue to move in a straight line.

The trailer will disengage.

The trailer will likely swing around.

The trailer will stop.

A trailer tends to swing around, potentially resulting in a trailer jackknife, if its wheels lock up.
