Alberta Air Brake Test 08

Practice tests aided in building confidence and reducing test anxiety. With the knowledge gained from the practice test and dedicated study and preparation, one can approach the official exam with a higher level of assurance and increase their chances of achieving a positive outcome. Furthermore, passing the Alberta Air Brake exam is essential for aspiring commercial drivers, who must ensure the safety of themselves and others on the road.

13 / 30

If there are system failures that affect braking ability, what needs to happen?

Complimentary Vehicular Safety Act

Commercial Vehicle Safety Alliance

Commercial Vehicle Secondary Air

None of the above

20 / 30

When does a loose air tank cause a failure?

None of the above

When the psi drop below 20 psi

It doesn't

21 / 30

What is the major issue of a kinked air line?

None of the above

It causes reductions in brake performance by restricting or blocking the flow of air pressure

It can cause the air line to be separated from the brakes

It stretches the air lines

22 / 30

What would you have to do to confirm that the brake chamber is securely installed?

Inspect the mounting fasteners and brackets

Test the brakes

Look on the ground for any loose pieces

None of the above

23 / 30
