    Bus driving jobs in Alberta are as diverse as the types of buses operated in the province. With a Class 2 licence, you can drive Class 2 buses (more than 24 passengers) and Class 4 buses (24 or fewer passengers). You can drive transit buses in a large city like Edmonton, including smaller buses to transport seniors or persons with disabilities. You can also drive coach and charter buses on long inter-city trips; shuttle buses at airports, hotels, or construction sites; and school buses (with a School Bus Endorsement).

    To apply for an Alberta Class 2 commercial driver’s licence, you must be at least 18 years of age, hold a Class 5 driver’s licence, submit a medical form completed by a doctor or nurse practitioner, and pass a vision test.

    Unlike most Canadian provinces, Alberta also requires aspiring Class 2 drivers to enroll in Mandatory Entry-Level Training (MELT). The MELT course includes classroom instruction, yard training (pre-trip inspections and basic maneuvers), and behind-the-wheel driving. Complete the classroom portion and pass a written knowledge test on the theory of driving Class 2 vehicles. You must score at least 80% to pass. Passing the test enables you to obtain a Class 2 learner’s licence, which will allow you to practice commercial driving under supervision.

    Most Class 2 buses have air brakes, so you should become qualified to operate air brakes. First, you should complete an approved air brake course and pass the official Air Brake knowledge test. You can take the Class 2 and Air Brake knowledge tests on the same day.

    Before you may take the road test for a Class 2 licence, you must complete MELT and (to be qualified on air brakes) pass a practical test on air brakes.

    The Commercial Driver’s Guide and the Air Brake Manual – A Guide for Students are the official references for aspiring commercial drivers in the province. However, if you would like more intensive knowledge training to ensure you pass the Class 2 knowledge test on your first try, we can help!

    This 50-question Alberta Class 2 Knowledge practice test, the first of twelve such tests we offer, covers the basics of operating Class 2 vehicles. All practice questions are based on the above two Alberta references. If you get stuck on a question, ask our AI Assistant to give you a hint, discuss the question in more depth, or answer your own questions about commercial driving. If you still miss the question, the AI Assistant will immediately give you the correct answer and an explanation.
