When a person successfully completes an approved Alberta air brake course through an authorized agency, an air brake endorsement (the letter Q) will be placed on that driver's licence.

An air brake endorsement is required for drivers of vehicles with:

  • an air-only braking system, or
  • a combination of air and hydraulic braking system

For information on taking an approved air brake course, please refer to: Air Brake Program.
