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. All applicants holding or receiving a Class 1, 2, 3, or 4 driver’s license are required to provide a satisfactory medical report upon initial application and on a regular cycle. You must take a written commercial and sign test along with a vision test. You will also require an air brake endorsement for those vehicles equipped with air brakes.

In order to successfully prepare, consider utilizing these exams and official New Brunswick 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.
