To obtain this endorsement, drivers must pass a written knowledge test and a practical hands-on test that demonstrates their ability to properly inspect, maintain, and safely operate the vehicle’s air brake system. The Alberta Air Brake Program was implemented to ensure that commercial drivers on the road have the necessary skills and knowledge to effectively control their vehicle’s speed and maintain the safety of themselves and other road users. This program has significantly reduced the number of accidents caused by brake failure, ultimately making Alberta’s roads safer for everyone.

Drivingtest.ca has prepared this Air Brake practice test to assist drivers in understanding air brake systems. This practice test and practical instruction will assist drivers in operating air brake-equipped vehicles before and after obtaining their Alberta air brake endorsement.

To successfully prepare, consider utilizing these exams and the official Alberta “Air Brake Manual – A Guide for Students” to your advantage. The more knowledge you can attain, the better it will be for you once you decide to return to the license office to take the air brake license written knowledge test.
