1 . What is another name for the service line?

The power line

The trailer service air line is also referred to as the control line or signal line.

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

Placed as high as possible inside the trailer.

Placed as low as possible inside the trailer.

Placed on the passenger side of the trailer.

Placed on the driver’s side of the trailer.

To reduce the risk of a rollover, the weight of cargo in a trailer should be kept as low to the ground as possible. Weight should not be placed primarily on one side of the trailer as this could make the trailer lean, increasing the risk of a rollover.

3 . If a load is placed on one side of a trailer, the trailer:

May lean, and could result in a rollover.

May add extra support during turns.

Have improved braking.

Have improved steering.

If the weight of a load is placed primarily one side of a trailer, the trailer may lean, increasing the risk of a rollover.

4 . If you need to back your trailer but cannot back up in a straight path, you should:

Back toward the passenger's side.

Back toward the driver's side.

Swerve back and forth while backing.

Always turn to your right.

If you need to back your trailer but cannot back up in a straight path, you should back on a curved path toward the driver's side of the vehicle. This will permit you the best possible visibility while backing.

5 . When coupling a trailer:

Make sure to couple matching glad hands.

Any glad hand can be connected to any other glad hand.

It is best to leave one glad hand unattached.

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.

6 . If a parked trailer does not have spring brakes, you should keep the trailer from moving by:

Using the air brakes.

Using wheel chocks.

Parking near a wall.

Parking on a slight incline.

If a parked trailer does not have spring brakes, wheel chocks should be used to prevent it from moving. Air brakes can only hold a parked trailer for as long as there is air pressure remaining in the air tanks, so wheel chocks will ensure safety.

7 . Rollovers are most likely to happen when:

Drivers turn too fast.

Driver turn too slowly.

It is windy.

It is raining.

Rollovers happen when an operator turns too fast. Drivers should be sure to slow down before entering turns and curves, especially when transporting a fully-loaded rig.
