Which endorsement is required to operate air brake-equipped vehicles?

• A. Q endorsement
• B. N endorsement
• C. P endorsement
• D. Z endorsement

Answer: (A)

Air brakes require a dedicated qualification on your Class 1 license to ensure you can operate and manage the system safely. In Alberta, the endorsement that covers air braking is the Q endorsement. It shows you’ve demonstrated the knowledge and skills needed to inspect, handle, and operate air brake systems, including how they integrate with the vehicle’s controls and the proper procedures for use and safety checks. Without this endorsement, driving a vehicle equipped with air brakes isn’t legal. The other endorsements relate to different vehicle types or features and do not certify air brake competency.
