15 . When coupling a trailer:

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.

16 . If the trailer begins to skid, it is best to:

Brake. If your trailer begins to skid, you should release the brakes to help regain traction. Once the wheels grip the road again, the trailer will begin to straighten out and follow the path of the tractor.

17 . 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.

18 . Look for matching colors when coupling glad hands. Service lines are often:

Blue. When coupling glad hands, make sure to couple together matching glad hands. To help drivers avoid mistakes, color coding is sometimes used. Service lines are often coded with the color blue and emergency lines are often coded with the color red.

19 . If your trailer begins to drift off course while you are backing, you should:

Return the steering wheel to the 12 o’clock position. If your trailer begins to drift while you are backing, you should correct the drift immediately by turning the top of the steering wheel in the direction of the drift.

20 . The trailer hand valve:

Should only be used when transporting cargo. The trailer hand valve should not be used for parking. This could cause all of the air to leak out of the braking system, resulting in the brakes releasing. Instead, use the parking brake.
