The province mandates that all drivers of vehicles equipped with air brakes must possess an air brake endorsement on their license. This endorsement requires drivers to take a written and practical examination to demonstrate their knowledge and skills. The practical exam includes tasks such as conducting pre-trip inspections, performing brake tests, and identifying and correcting brake system defects. This strict regulation ensures that only trained professionals operate vehicles equipped with air brakes, minimizing the risk of accidents and injuries. In addition, commercial vehicle operators in British Columbia are subject to regular inspection and maintenance requirements to ensure their vehicles’ safe operation further. Overall, the province’s focus on promoting air brake safety helps to protect both drivers and the public on the roads.

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.
