Practice on the go and jump straight back to where you left off.
About the exam
In Quebec, driving a straight truck (Class 3) requires passing the SAAQ theory exam, then the circle check and the road test. A Class 5 licence is required first.
According to SAAQ policy PO-PM 05 (December 2025), the Class 3 theory exam has 32 questions, with 24 correct answers to pass. After a failure, you can retake it after 7 days. Class 3 has no separate road signs or Highway Safety Code exam: you must already hold Class 5.
ExamHub's free quiz has 150 original questions (French first, English translation) drawn from the guide « Conduire un véhicule lourd » (2024): Class 3 and the straight truck, securement, loads and dimensions, driving the straight truck, then the common core of Classes 1, 2 and 3.

Five questions from the bank, with the answer and the explanation.
Why: The pass mark for the Class 3 specialized theory exam is 24 out of 32, the same as for Classes 1 and 2. The 22 out of 30 applies to Classes 4A and 4B, the 15 out of 20 to endorsement F, and the 9 out of 12 to Class 5.
Why: A permanent-equipment trailer weighing more than 2,000 kg and less than 4,500 kg is still covered by Class 3.
Why: The total WLL of the securement system must not be less than 50% of the cargo mass; here, 3,500 kg is enough.
Why: With a straight truck or a bus, you turn the steering wheel toward the side you want the rear to go; with a tractor and semi-trailer, it is the opposite.
Why: The inspection is done before getting behind the wheel and no later than 80 km from the loading point, then after 3 hours or 240 km.
