1 . Trailers built before 1975 are:

Required to have spring brakes.

Not required to have spring brakes.

Unsafe to drive.

Prohibited from public roadways.

Trailers built before 1975 are not required to have spring brakes. When parking a trailer without spring brakes, be sure to use wheel chocks to prevent the trailer from rolling.

2 . When the wheels of a trailer lock up:

The trailer will stay straight.

The trailer tends to swing around.

The cab will swing, but the trailer will stay straight.

They will likely go flat.

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

3 . The trailer hand valve:

Should always be used for parking.

Should only be used for parking on a downhill.

Should never be used for parking.

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.

4 . During a trip, landing gear should be:

Completely raised.

Completely lowered.

Skimming the pavement.

Landing gear, or trailer supports, should always be completely raised before a vehicle is driven. Landing gear that is not entirely raised could catch on railroad tracks or other hazards on the roadway.

5 . 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.

6 . If colors are being used to distinguish glad hands, which color is used for emergency lines?

Orange

Yellow

Blue

Red

When trailer air lines are color-coded, the service lines are generally blue and the emergency lines are generally red.

7 . If the emergency air line loses pressure:

The service brakes will activate.

The tractor protection valve will close.

The rear trailer will detach from the combination.

The tractor protection valve keeps air in the trailer's braking system should the trailer break away or develop a leak. A loss of air pressure in the emergency line will cause the tractor protection valve to open and the emergency trailer brakes to activate.

The CDL Bus driving test evaluates several skills. These include pre-trip vehicle inspection, basic vehicle control (backing, moving forward, stopping, and turning), and on-road driving. On-road driving assesses your ability to handle intersections, railway crossings, curves, and more. You'll also be evaluated on how well you manage traffic and emergencies, and your knowledge of bus safety rules.
