Alberta Air Brake Test 02

From understanding air brake system components and their functions to conducting pre-trip inspections, the practice test rigorously prepared you with the knowledge and skills required to pass the official exam with flying colors. Additionally, the test helped build my confidence as I became more familiar with the exam format. Ultimately, passing the Alberta Air Brake exam brought a great sense of accomplishment, knowing that I thoroughly understood air brake systems and the ability to operate commercial vehicles safely.

10 minutes

5 minutes

3 minutes

15 minutes

19 / 30

When does contamination drain most effectively?

Once more air is forced through the system

Once the park brakes are applied

It doesn't

After the tanks are empty

20 / 30

What is another name that the supply tank is called?

None of the above

The purge tank

The main tank

The air tank

21 / 30

Only if close to the engine

None of the above

When releasing the air system

Yes

22 / 30

Vehicle weight

Air pressure

Trailer weight

None of the above

23 / 30

What does the supply circuit do?

Adjust the tire pressure
