About the exam
In Quebec, driving a combination of road vehicles (a road tractor and its semi-trailer, a straight truck towing a heavy trailer, or a road train) requires a class 1 licence. You must first hold a class 5 licence. Endorsement T (road train over 25 m) is added after 5 years with class 1 and special training; endorsement F (air brakes) and endorsement M (manual transmission) are obtained separately.
Under SAAQ policy PO-PM 05 (December 2025), the class 1 theory exam has 32 questions and you need 24 correct answers to pass (75%). The circle check and the road test each require 75 out of 100. After failing the theory exam, you can retake it after 7 days. The SAAQ does not publish the length of the theory exam; ExamHub's test mode gives you 45 minutes.
ExamHub's free practice test has 150 original questions (written in French, with an English translation) based on the free SAAQ guide "Conduire un véhicule lourd" (10th ed., 2024). Nearly half cover class 1: licence and endorsements, coupling and uncoupling, road trains, driving a combination, loads and dimensions. The rest is the material shared by classes 1, 2 and 3. These are not the questions from the real exam.

Five examples from the question bank, with the answer and the explanation.
Why: Class 1 requires 24 correct answers out of 32 (75%). The figures 22 out of 30, 27 out of 32 and 15 out of 20 are those of classes 4A and 4B, motorcycles (6R) and the F endorsement.
Why: If the semi-trailer is too high, you lower it with the landing gear. If it is too low, you lower the tractor suspension or raise it with the landing gear.
Why: The Regulation requires 1 HP per 180 kg of gross loaded mass: 67,500 ÷ 180 = 375 HP.
Why: When the jackknife angle exceeds 15 degrees, the point of no return is reached. The tractor and trailer then fold to more than 90°.
Why: Driving is prohibited once 13 hours of driving, 14 hours of work or 16 elapsed hours have accumulated since the start of the shift.
