To ensure that drivers operating commercial vehicles equipped with air brakes are correctly trained and qualified, they must pass an Air Brake Endorsement Test. This exam covers various topics related to air brakes, including the principles, components, and operation of air brake systems. Drivers must comprehensively understand air brake functioning and maintenance to ensure they can respond appropriately in emergencies. In Quebec, air brakes are subject to regular inspections, and violations of air brake regulations can result in significant fines and penalties. Overall, air brake safety measures in Quebec are vital for ensuring the safety of all those on the road.

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 Quebec air brake F endorsement. To operate vehicles equipped with air brakes on a highway (other than a vehicle defined as a construction vehicle), you must have a Quebec driver’s license with an air brake F endorsement.

To successfully prepare, consider utilizing these exams and the official Quebec “driving a heavy vehicle” manual (chapter 4) 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.
