This endorsement is necessary for operating any vehicle equipped with air brakes or a combination of air and hydraulic brakes. To obtain the endorsement, drivers must pass a written test on air brake components, theory, and operation and a practical test demonstrating their ability to use the brakes properly. Additionally, all air brake systems in British Columbia must meet specific requirements and regulations, including installing automatic slack adjusters and proper brake adjustment procedures. These regulations exist to ensure the safe operation of air brake-equipped vehicles on British Columbia’s roadways.

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.
