It is recommended that you take a practice test before you take the actual written test. Please note, however, that this is not the actual test, and you will not receive your license if you pass this sample practice test. If you’re getting your commercial licence, you've come to the right place.

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

In order to successfully prepare, consider utilizing these exams and 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 make your way back into the licence office to take the air brake licence written knowledge test.
