Since the introduction of the mandatory air brake endorsement in 1996, all drivers of commercial vehicles with air brakes must pass a practical and written test to receive this endorsement. The practical test evaluates the driver’s ability to conduct a pre-trip inspection of the air brake system, perform a brake check, and complete a controlled stop. The written test covers the theory and operation of air brakes, including the various components involved in the system and how they work together to slow and stop a vehicle safely. Furthermore, Manitoba government officials recognize the importance of keeping air brake training and endorsement requirements up to date with current industry standards. As such, Manitoba is one of the few jurisdictions in North America that has implemented mandatory air brake endorsement renewals for commercial drivers. By ensuring that drivers are knowledgeable and trained on air brake systems, Manitoba is proactively promoting road safety for all Manitobans.

Drivingtest.ca has prepared this Air Brake practice test to assist drivers in understanding an air brake system’s essential operation and function. Requirements for Air Brake Endorsement are:

1) Must complete an Air Brake Written Test

2) Must complete an Air Brake Practical Test.

This endorsement permits the holder to drive vehicles equipped with air brakes in the vehicle class for which the driver is licensed.

To successfully prepare, consider utilizing these exams and the official Manitoba Air Brake Manual to your advantage. The more knowledge you can attain, the better it will be for you once you return to the MPI office to take the air brake license written knowledge test.
