1 . When the wheels of a trailer lock up:

The trailer will be drivable.

The trailer may swing around.

The vehicle will maintain steering.

A trailer may swing out and strike other vehicles if its wheels lock up. This is especially likely with lightly-loaded trailers.

2 . Older trailers are not equipped with spring brakes. This means that if the air supply for a vehicle's air braking system leaks away:

The trailer will stop normally.

The trailer will not have brakes.

The trailer will speed up.

Older trailers do not have spring brakes. This means that if the air supply in an older trailer's air tank has leaked away, there will be no working brakes connected to the trailer and its wheels will turn freely.

3 . When coupling:

You can assume all vehicles are the same.

Be sure that you are coupling correctly.

Cracks in the mounting are acceptable.

Incorrect coupling and uncoupling of combination vehicles can have extremely dangerous consequences.

4 . When driving with trailers, you should:

Make quick, sudden changes.

Avoid making sudden moves.

Accelerate by pushing the accelerator to the floor.

To reduce the risk of tipping over when driving with a trailer, you should steer gently and smoothly. Avoid making sudden movements.

5 . 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.

6 . The trailer hand valve:

Should always be used for parking.

Should only be used for parking on a downgrade.

Should never be used for parking.

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. Instead, use the parking brake or wheel chocks.

7 . Having anti-lock brakes on only one axle:

Will not make a difference in braking.

Will provide increased control in braking.

Will likely cause the air brakes to malfunction.

If a vehicle has anti-lock brakes on just one axle, the driver will still have more control during braking than they would without any anti-lock brakes.
