1 . What must be on an air tank in an air-braked vehicle?

A check valve

A lock

A trap door

An oxidizer

All air tanks on air-braked vehicles must have one-way check valves located between the air compressor and the first reservoir. This prevents air from flowing out in the event of a leak.

2 . When a tire goes flat, you may hear a loud bang. The truck will be affected:

Immediately.

After a short delay.

Only if the damaged tire is near the front of the truck.

Only if the truck is hauling a load.

There may be a delay of a few seconds between the sound of a tire failing and the time that the vehicle is affected by the tire failure. Because of the short delay, a driver may initially believe that the sound came from another vehicle.

3 . If unsure if a road is becoming icy, a driver can:

Guess.

Open the window and check the front of the mirror for ice.

Try to look at the road closely.

Look at a weather forecast.

If you think the road surface may be becoming icy, you can check for ice on your vehicle by opening the window and feeling the front of the side mirror, mirror support, or antenna. If ice has formed on any of these items, the road is likely becoming icy as well.

4 . When doing an inspection, ensure that the brake pads are:

Covered with grease.

Covered with coolant.

Covered with oil.

Free of oil or grease.

When inspecting a vehicle's brakes, you should make sure the shoes and pads do not have oil, grease, or brake fluid on them.

5 . Why do drivers have to inspect their vehicles?

It is usually a company policy.

It is usually a local ordinance.

It is a federal and state law.

It adds to the amount of time for which they will be paid.

Federal and state laws require drivers to inspect their vehicles before driving to ensure that they are safe to operate.

6 . When the spring brakes are activated in a vehicle with air brakes, you should never:

Turn on the lights.

Turn the vehicle off.

Push the brake pedal down.

Open the trailer doors.

In a vehicle with air brakes, never push the brake pedal down when the spring brakes are activated. The combined force of the springs and the pressure of the air brakes could damage the brakes.

7 . An Anti-Lock Braking System (ABS):

Cannot be used with air brakes.

Should be used on dry pavement.

Can assist in maintaining control when braking.

Should only be used if all axles have ABS.

Anti-Lock Braking Systems (ABS) are compatible with air braking systems. ABS helps maintain control of a vehicle and prevents the wheels from locking up during hard braking on slippery surfaces. ABS can still provide benefits even if is present on only one axle.
