FREE AB General Knowledge Test 1 2025
The transportation industry in Alberta is booming, and truck drivers are in high demand. If you are considering a career change, now is the perfect time to take the first step and obtain a Commercial Driver’s Licence. Alberta offers four classes of commercial licenses: Class 1, Class 2, Class 3, and Class 4. Each class has specific requirements, but one thing they all have in common is the requirement to pass the general knowledge test. Aspiring commercial drivers must take a 30-question written exam based on the official Alberta Commercial Driver’s Guide. A minimum score of 83% is required to pass.
