Alberta Class 1 Knowledge Test Questions 2026: Worked Examples

None of the Alberta pages read for this guide publishes the questions on the Alberta Class 1 knowledge test, so the best guide to what you will be asked is the material Alberta says the test draws on: the Commercial Driver’s Guide, the Driver’s Guide: Cars and Light Trucks and the Class 1 Learning Pathway curriculum. This page shows what that means in practice, chapter by chapter, and works through two practice questions in full. They are ProSyllabus’s own questions, written from the guide, and two of the three free questions in our practice test.

ProSyllabus is an independent study site. It is not part of the Government of Alberta, Transportation and Economic Corridors or any registry agent, and nothing here is the official test. Every rule on this page is quoted or summarised from the official pages listed at the foot of the page.

The guide says the test asks about safe driving practices, driving laws and road signs, and that Class 1 applicants may be asked questions from the other chapters of the guide too. Our own practice questions, written from the guide, fall into a few kinds:

Why it matters: the guide teaches two hours-of-service rules side by side, and our practice questions tell you which applies with a phrase such as "operates only within Alberta". The driving limit (13 hours) is the same under both; the 15-hour provincial versus 14-hour federal on-duty limit is one difference, and the federal rule adds other limits.

Why it matters: air pressure is what applies air brakes, and every brake application and release uses some. Several of our practice questions turn on what spends air and what saves it, which is why the guide makes lower gears the main way to control speed on a downgrade, with moderate or intermittent braking and no pumping of the air brakes.

When you study a rule with a number, learn both the figure and its conditions. These five appear in the Commercial Driver’s Guide with exact figures; learn the figure and the condition attached to it.

Each of these comes with a condition that a question can turn on: the inspection figure is a time window, not a calendar day; the tread figure depends on the axle; the leakage allowance grows with each trailer. Read the whole stem before you choose.

The guide’s contents run to ten chapters. Use the chapter map to organise revision: the guide says chapters 1 to 5, 9 and 10 apply to every licence class, chapter 6 holds class-specific operations, chapter 7 is mainly for Class 2 and 4 drivers and chapter 8 mainly for Class 1 and 3.

The air brake (Q) knowledge test is not part of the Class 1 test. On the standard route it is taken at a registry agent after an approved air brake course and practical assessment (some eligible technicians and mechanics may skip the training), with the Notice of Air Brake Program Completion. It is also 30 multiple-choice questions, 25 correct to pass, ending automatically at 6 wrong, with no time limit and no limit on attempts; retests are on a different day. The guide’s own trip air brake inspection (p36) gives the pressures a driver checks: the trailer air supply valve popping out at 40 to 60 PSI or higher, the low air warning by 60 PSI, the park control valve popping out at 20 to 45 PSI, and the build-up, cut-out and leakage figures above.

Practise in three passes. First, read one chapter of the guide and answer questions on that chapter only, so you learn the rules while they are fresh. Second, mix the chapters in sets of 30, the length of Alberta’s test, and note every question you missed by chapter. Third, reread the chapters where you lost the most marks before you mix again. Aim to be clear of 25 out of 30 on fresh questions, not on ones you have seen.

When you miss a question, read the explanation back to the page it cites. Review each missed question against its cited source.
