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.


Before learning to drive a Class 1, Class 2, Class 3 or Class 4 vehicle, you must get authorized instruction in the class of vehicle you want to be licensed in. For each section of these practice test, we have multiple practice tests. Requirements for Air Brake Endorsement are 1) Must complete an Air Brake Written Test 2) Must complete an Air Brake Practical Test.

In order to successfully prepare, consider utilizing these exams and official Nova Scotia 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 SNB office to take the air brake licence written knowledge test.
