Canada Air Brake Endorsement Knowledge Test (Alberta Q, Ontario Z)

In Alberta and Ontario you need an air brake endorsement on your licence to drive a vehicle with air brakes: the Q endorsement in Alberta (drivers of a single-motor farm vehicle are exempt) and the Z endorsement in Ontario. On Alberta's standard route you first complete an approved course (at least 6.5 hours in the classroom, then practical training and a practical assessment; some eligible mechanics and technicians may take the tests without the training), then take the knowledge test at a registry agent: 30 multiple-choice questions, 25 correct to pass, and the test ends if you get 6 wrong. There is no time limit, it is in English only, and a retest must be on a different day. In Ontario you take the air brake knowledge test and a practical test at a DriveTest centre, or take an air brake endorsement course and bring its referral envelope to a DriveTest centre within 6 months (holders of a B, C, D, E, F or G licence take the course with a vehicle fleet owner). Our practice questions cover how the air supply, service, spring and trailer brakes work, brake adjustment, and the air brake pre-trip inspection.
