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

What do the air pressure gauges measure?

Air pressure from both primary and secondary tanks

Air pressure from the primary tank

Air pressure from the secondary tank

The air in the park brakes

16 / 30

What is the purpose of the Commercial Vehicle Safety Alliance (CVSA)?

To record all deficiencies with commercial vehicles across North America

It's club for all commercial vehicle drivers

17 / 30

What allows the brakes to release more rapidly?

When the driver releases their foot from the brake pedal

Nothing

When the chambers are not full of air

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

18 / 30

Are trainer service and park circuits the same as truck and bus circuits?

Yes

Only the same as bus circuits

Only the same as truck circuits

19 / 30

21 / 30

What does air brake antifreeze essentially do?

Nothing

22 / 30

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

Through the rotors
