Alberta Air Brake Test 03

Taking the Alberta Air Brake practice test is essential to obtaining the required certification to operate vehicles equipped with air brakes. Not only does the practice test help you gauge your knowledge, but it also helps you prepare for the official exam. It is a means to identify gaps in your understanding and provides an opportunity to rectify them. Carrying out ample practice can help you pass the exam with flying colors.

15 / 30

When do the tanks drain properly?

None of the above

After sitting idle for two hours

16 / 30

What does Type 20 typically refer to?

The typical size of brake chambers for steering axels

Nothing

The typical size of brake chambers for trailer axels

The typical size of brake chambers for power axels

17 / 30

What does air brake antifreeze essentially do?

To keep the air hoses from freezing

Nothing

To prevent the air from freezing

To prevent rubber components in the valves from drying out

18 / 30

What allows the brakes to release more rapidly?

Nothing

When the driver releases their foot from the brake pedal

When the chambers are not full of air

When air pressure in the brake chambers exhausts through the quick release valve

19 / 30

The low air alarm is set to activate if air pressure drops below what psi?

60 psi

50 psi

70 psi

80 psi

20 / 30

Does every axle group will have an independent service brake circuit?

Yes

Some do

Just the last axle group

21 / 30

When the brakes are released, where is the air typically released through?

Through the air dryers

Through the rotors

Through the couplers

Through the quick release valve

22 / 30

Since not all trailers should have alcohol-based antifreeze, how would you know if they should?

You would be able to smell it

You would have to trust your maintenance team

The year the trailer was built

There will be a decal fitted to the front of the trailer warning against alcohol use

23 / 30
