1 . To help prevent a rollover, cargo should be:

Placed as high as possible inside a trailer.

Placed as low as possible inside a trailer.

Placed on the driver’s side of a trailer.

If a vehicle is top-heavy, it is more likely to roll over. The weight of cargo should be positioned as low in a trailer as possible to minimize this risk.

2 . A combination vehicle has ____ air line(s).

One

Two

Three

Every combination vehicle has two air lines: the service line and the emergency line.

3 . During a trip, landing gear should be:

Completely raised.

Completely lowered.

Skimming the pavement.

Landing gear, or trailer supports, should always be completely raised before a vehicle is driven. Landing gear that is not entirely raised could catch on railroad tracks or other hazards on the roadway.

4 . When testing ____, you should apply your vehicle's brakes with the hand control while moving the vehicle forward slowly.

The Anti-Lock Braking System

The emergency braking system

The trailer service brakes

To test the trailer service brakes, you should first ensure that the braking system has a normal air pressure level, then release the parking brake. You should then move the vehicle forward slowly and apply the brakes with the hand control. If the trailer service brakes are working properly, you will feel the brakes activate.

5 . A trolley valve:

Should be used while driving.

Should only be used to test trailer brakes.

Should be used when parking uphill.

The trailer hand valve (also referred to as the trolley valve or Johnson bar) is a mechanism that works the trailer brakes. It should only be used to test the brakes. Using it while the vehicle is being driven could cause a skid. Never use the trailer hand valve while parking because doing so may release the air pressure from the braking system, releasing the brakes that are holding the vehicle in place.

6 . If the emergency air line loses pressure:

The Anti-Lock Braking System will activate.

The service air line will activate.

The emergency brakes will activate.

The emergency air line controls the emergency brakes on a combination vehicle. A loss of air pressure in the emergency line will cause the emergency trailer brakes to activate.

7 . Keeping cargo centered on a rig can:

Help you drive faster.

Prevent a rollover.

Make turns more dangerous.

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.
