Drivers who intend to operate such vehicles must undergo a comprehensive air brake endorsement training program that includes theoretical and practical components. The theory portion covers air brake systems, components, control systems, and ins and outs of coupling and uncoupling trailers. In addition, drivers must pass a written test and complete practical training that includes inspecting air brake systems, testing the low air warning system, and conducting a brake performance test. Failure to comply with these regulations can result in severe penalties and even a driver’s license suspension. Compliance with these regulations ensures that the vehicles equipped with air brake systems are maintained and operated safely, reducing the risk of accidents and ensuring the safety of all road users in British Columbia.

Drivingtest.ca has prepared this Air Brake practice test to assist drivers in understanding air brake systems. This practice test and practical instruction will help drivers operate air brake-equipped vehicles before and after obtaining their BC air brake endorsement. To operate vehicles equipped with air brakes on a highway (other than a vehicle defined as a construction vehicle), you must have a B.C. driver’s license with an air brake endorsement (code 15). Endorsement code 15 is shown in the “restrictions” section of a driver’s
license.

To successfully prepare, consider utilizing these exams and the official BC “driving commercial vehicles -a Guide for professional drivers” 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.
