To operate these vehicles, drivers must hold a valid air brake endorsement on their driver’s license. This endorsement requires passing a written and practical air brake test to ensure the driver understands how the system works and can properly maintain and operate the vehicle. Regular system inspections are also required to ensure that it is functioning correctly. The air brake system in Manitoba vehicles uses compressed air to activate brakes, providing a more reliable and effective method of stopping the vehicle. Implementing air brakes has significantly improved vehicle safety in Manitoba, reducing the likelihood of accidents caused by brake failure. The provincial government has also recognized the importance of air brakes, which has established strict regulations to ensure that this safety feature is properly maintained and used by drivers.

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.
