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.

16 / 30

What is the definition of compressed air with regard to air brakes?

A small amount of air placed in a larger tanks

It's just air

Specially treated air

Compressed air that is pressed into a smaller space

17 / 30

If there is a small air leak, how does the air brake system adjust on the fly?

If near the coupler

Only when close to the compressor

Yes

23 / 30

Which statement is false? The supply tank functions:

It collects contamination not captured by the air dryer
