This endorsement is issued only after the completion of a specialized air brake course accredited by the province. The course covers in detail the mechanics of the braking system, emergency situations, and proper maintenance of the air brake system. Furthermore, Manitoba regulates the frequency of air brake inspections, which must be completed regularly to ensure the system remains in good working order. These regulations help ensure the safety of both the driver and the public while on the road. Manitoba’s strict approach towards air brake regulations has made it a leader in safe commercial driving practices across Canada.

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.
