1 . 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.

2 . Before backing your tractor under the trailer, make sure your trailer brakes are:

Disengaged.

Locked.

Deactivated.

Dry.

Correctly following the steps to couple and uncouple trailers is vital to safely operating a combination vehicle. Before backing your tractor under the trailer while coupling, make sure your trailer brakes are locked.

3 . The trailer hand valve should:

Be used for parking.

Be used only to test the trailer brakes.

Be used together with the brake pedal.

Be used on slippery surfaces.

The trailer hand valve works the trailer brakes but should only be used when testing them. Using it while driving could create 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.

4 . When driving a bobtail tractor, you should be aware that:

Bobtails stop very easily.

Bobtails cannot drive as fast as tractors with semitrailers.

Bobtails are more difficult to stop than tractors with semitrailers.

Bobtails are illegal in most states.

Bobtail tractors are tractors that are not attached to any semitrailers. When operating a bobtail, you should be aware that stopping can be difficult and that it will take a longer distance to bring the bobtail to a complete stop than it would a tractor attached to a loaded semitrailer.

5 . Rollovers happen when drivers:

Turn too quickly.

Do not driving fast enough.

Pay attention to the road.

Drive illegally.

A rollover happens as a result of a driver taking a turn at too high a speed. Be sure to take turns and curves safely and slowly.

6 . If unsure if a trailer is equipped with ABS, you can:

Check under the trailer for wheel speed sensors coming from the back of the brakes.

Try driving on a slippery surface and see if ABS kicks in.

Assume it does have ABS.

Remove a tire and look for the ABS sensor on the axle.

Trailers and converter dollies built on or after March 1, 1998 are required to have Anti-Lock Braking Systems (ABS). This will be indicated by the presence of a yellow malfunction lamp. You can determine if older trailers have ABS by checking under the trailers for ECU and wheel speed sensor wires coming from the back of the brakes.

7 . Making a quick lane change while pulling multiple trailers is usually safer than making a quick lane change while pulling only one trailer.

True

False

Double and triple combinations are less stable than single commercial vehicles. They are more likely to roll over when being driven with quick movements. Doubles and triples must be driven very smoothly and gently.
