What Tests Must Be Cleared to Become a Professional Driver in Canada?
Here’s an in-depth guide to the tests you must clear to become a professional driver in Canada.

Becoming a professional driver in Canada is a rewarding career path, but it doesn’t happen overnight. It involves passing a series of tests and obtaining the right licences and endorsements. These requirements vary by province and by the category of commercial driving you want to pursue — from trucks and buses to taxis and school buses.
Here’s an in-depth guide to the tests you must clear to become a professional driver in Canada.
🛣️ 1. Begin with a G-Class Licence
All drivers must first obtain a G licence in their province:
-
G1 Knowledge Test: A written test covering traffic signs, rules of the road, and basic driving knowledge.
-
G2 Road Test: An on-road test assessing basic driving abilities.
-
G Road Test: An advanced test focusing on highway driving, lane changes, and other complex maneuvers.
If you’re starting out, consider enrolling in a driving school in Milton — many have expert trainers and tailored courses that make passing the G and G2/G road tests much smoother.
🛻 2. Commercial Driving Licence Tests
To drive trucks, buses, or other commercial vehicles, you must upgrade your licence and pass additional tests:
🚚 A. AZ Licence (Tractor-Trailers)
-
Written Test: Covers commercial traffic rules, air brake knowledge, and general driving theory.
-
Air Brake Endorsement Test (Z): An additional test assessing air brake proficiency.
-
Road Test: Evaluates your ability to operate a tractor-trailer, including inspection, coupling/uncoupling, and city and highway driving.
🚛 B. DZ Licence (Straight Trucks)
-
Written Test: Similar to AZ but focused on straight trucks.
-
Air Brake Endorsement Test (if required): Depending on the equipment you’ll operate.
-
Road Test: Evaluates inspection routine and driving proficiency for straight trucks.
🚌 C. B, C, E, F Licences (Bus & School Bus Driving)
-
Written Test: Covers bus regulations, passenger safety, and air brake knowledge (if applicable).
-
Road Test: Evaluates bus maneuvering, stopping, and safe passenger handling.
For those located in Mississauga, working with an experienced driving instructor in Mississauga can make a significant difference — especially when it comes to mastering bus or truck driving techniques.
👁️ 3. Medical and Vision Testing
All professional drivers must:
-
Pass a vision test for sharp eyesight and peripheral vision.
-
Complete a medical examination conducted by a doctor.
(Medical fitness must be renewed periodically.)
📋 4. Additional Specialized Training
Some licences require formal training:
-
MELT (Mandatory Entry-Level Training): A required program for AZ licence holders across Canada.
-
Additional Certifications: Depending on the role — e.g., WHMIS or TDG for transporting hazardous materials, or specialized training for school bus or emergency vehicle operation.
🏁 Final Thoughts
Becoming a professional driver in Canada goes far beyond obtaining a basic G licence. You must clear a series of knowledge and road tests, obtain medical and air brake endorsements, and sometimes complete specialized training like MELT.
With the right preparation, quality instruction, and practice, you can build a successful, rewarding career on the road. Consider enrolling in a driving school in Milton for a strong foundation, or working with an experienced driving instructor in Mississauga to hone your skills for higher licence classes.
