FREE AB Class 2 (Bus) Commercial Licence Practice Test

If you’re aiming to become a bus driver in Alberta, you’ll need a Class 2 Commercial Driver’s Licence. This license allows you to operate buses, including school buses, special activity buses, and special vehicles used to transport passengers. The demand for professional bus drivers is consistent, as they play a key role in public and private transportation sectors. To prepare for the road, thorough study and practice are vital. You must pass both knowledge and road tests to obtain your licence.

The knowledge test consists of multiple-choice questions based on the official Alberta Commercial Driver’s Guide, and you need to score at least 80% to pass—although this benchmark is subject to change as per Alberta Transportation regulations. The test typically takes about 30 minutes to complete. During the road test, you’ll demonstrate your practical skills in bus operation to an examiner.

While the official guide is an indispensable resource, practice tests offer the hands-on experience that reading alone cannot. This practice test, featuring 50 questions, is tailored for the Alberta Class 2 licence aspirants. It’s derived from the 2024 AB Commercial Driver’s Guide, and each question comes with an explanation to deepen your understanding of the rules. Good luck, and remember, safety is paramount when you’re in the driver’s seat!
