Your score is

Alberta’s air brake endorsement program ensures that all drivers using air brakes understand the operation and maintenance of these vital components. The program consists of a written and practical skills test to ensure that drivers have the knowledge and skills to safely and effectively use air brakes. Proper maintenance of air brakes is also emphasized to ensure they are working correctly. This is particularly important in Alberta due to the harsh winter conditions, which can significantly increase wear and tear on a vehicle’s braking system. Overall, ensuring a thorough understanding and proper use of air brakes is essential to maintaining safe road conditions for all drivers in Alberta.

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.
