In Manitoba, drivers must pass an air brake test before obtaining a commercial driver’s license. This test ensures that drivers understand how to properly operate and maintain air brake systems, which is crucial for their safety and the safety of others on the road. Additionally, Manitoba requires annual air brake inspections to ensure all commercial vehicles have functioning air brakes. These inspections help prevent accidents caused by faulty braking systems. Overall, air brakes are a vital aspect of commercial vehicle operation in Manitoba, and they play a critical role in keeping the province’s roads safe and secure for everyone.

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.
