Wyoming CDL Air Brakes Test (2024) - FREE CDL Practice Test

1. To test the air leakage rate, with a fully-charged air system you should ____________ and time the air pressure drop.

turn off the engine, release the parking brake
put alcohol into the air system, run the engine at a fast idle
check the air compressor's drive belt, chock the wheels
release the parking brake, leave the engine running

2. Why must air tanks be drained?

To keep from fouling the air compressor oil.
Water and oil reduce the air pressure.
The low boiling point of water reduces braking power.
Water can freeze in cold weather and cause brake failure.

3. When a tire fails, you must:

hold the steering wheel firmly.
get out and check all the tires after you have come to a stop.
stay off the brake.
All of the above.

4. Your mirrors should be adjusted so that:

a part of the vehicle is visible in the mirror.
the rear of the vehicle is visible in the mirror.
more than half of the mirror shows the vehicle.
no part of the vehicle is visible in the mirror.

5. To test the service brake:

push the brake pedal firmly while going about 5 mph.
gently try to pull forward with the trailer parking brake on, then release the brake.
push the brake pedal firmly while slowly moving backward.
shift your transmission to a low gear, pump the brake pedal three times, then hold it down for five seconds.

6. The best way to know what's going on behind and to the sides of your vehicle is to:
