It is recommended that you take a practice test before you take the actual written test. Please note, however, that this is not the actual test, and you will not receive your license if you pass this sample practice test. If you’re getting your commercial licence, you've come to the right place.


This Air Brake practice test has been prepared by Drivingtest.ca to assist drivers in understanding the basic operation and function of an air brake system.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 class of vehicle for which the driver is licenced.

In order to successfully prepare, consider utilizing these exams and official Manitoba Air Brake Manual to your advantage. The more knowledge you can attain, the better it will be for you once you decide to make your way back into the MPI office to take the air brake licence written knowledge test.
