1 . What does an Anti-Lock Braking System (ABS) do?

It allows a vehicle's wheels to lock up.

It prevents a vehicle's wheels from locking up.

It makes turning a vehicle easier.

An Anti-Lock Braking System (ABS) helps prevent wheel lockup during hard braking. If ABS detects impending lockup, it reduces braking pressure to a safe level.

2 . When a combination vehicle goes around a corner:

The turn should be made as tightly as possible.

The front and rear wheels move in different paths.

The rear wheels should run over the curb.

It is acceptable for street signs to be knocked over if they are too close to the road.

When a vehicle goes around a corner, the rear wheels follow a different path than the front wheels. This is called off-tracking. This effect is especially pronounced on vehicles with trailers.

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 traveling more slowly than 40 mph, maintain at least ____ of following distance per every 10 feet of your vehicle.

One second

Two seconds

Three seconds

Four seconds

At speeds below 40 mph, you should allow at least one second of following distance for every 10 feet of your vehicle. Follow the same formula when traveling at faster speeds, then add one additional second to your following distance. Remember that larger vehicles require more space to stop than smaller vehicles.

5 . Trailers with low underneath clearance may be difficult to drive:

On interstate highways.

Over railroad crossings.

On dirt roads.

At the posted speed limit.

Railroad-highway crossings may be difficult to cross when pulling a trailer with a low underneath clearance. In particular, both low-slung units and single-axle tractors pulling long trailers are especially challenging to drive over raised crossings.

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

Release the brakes.

Accelerate.

Quickly turn the steering wheel one way, then the other.

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.

7 . The best way to notice if a trailer has begun to skid is to:

Ask another driver.

Use your mirrors to determine if the trailer has left the lane.

Look at the skid sensor.

Feel the tractor move.

The easiest way to become aware that your trailer has begun to skid is to observe it in your mirrors. Checking your trailer in your mirrors will also allow you to spot any skidding at the earliest possible moment.
