ExploreAbout this exam
The Class 1 licence is Saskatchewan's commercial driver credential, administered through SGI, and it is the licence that opens the door to heavy-truck and tractor-trailer work in the province. This independent study page is written for candidates preparing for the Class 1 knowledge test - people moving up from a Class 5 licence, drivers returning to commercial work, and newcomers to Saskatchewan's licensing system who need to understand how the process is organized before they book anything.
SGI's public site organizes the material a candidate needs into four areas, and this page follows the same structure: licence classes and knowledge test requirements, road tests and practical assessment, licensing, registration and online services (including MySGI and the plate calculator), and road safety, penalties and carriers/trucking. Together these cover what you must know before the written test, what the practical assessment involves, how to handle the paperwork and online tools around your licence, and the safety and penalty rules that apply once you are driving commercially.
Preparation advice: start with the licence-class material so you know exactly which test you are writing, then work through road-test expectations, then the administrative and safety domains. Use SGI's own published guides and pages as your authoritative reference, and treat practice questions - including ours - as a check on recall, not as a substitute for the source material. Saskatchewan conditions, winter driving, and carrier obligations deserve extra attention because they appear across several domains.
This page is an independent study resource. It is not affiliated with, endorsed by, or operated by SGI or the Government of Saskatchewan, and it does not reproduce any official question bank.
What you'll study
About SGI Class 1 preparation
Who needs a Class 1 licence in Saskatchewan?
The Class 1 licence is the commercial class for operating heavy trucks and tractor-trailers. If you plan to drive a semi or similar heavy combination for work, this is the class you are working toward. Confirm your exact vehicle against SGI's licence-class pages before you book, since the class must match the vehicle you will drive.
What does the Class 1 knowledge test cover?
Expect questions on licence classes and test requirements, road-test and practical assessment expectations, licensing and registration processes including online services, and road safety, penalties and carrier rules. Our page groups practice material into those four areas so you can see which domain is costing you marks.
How hard is the knowledge test?
Difficulty depends mostly on how well you know Saskatchewan-specific rules rather than general driving intuition. Candidates who have driven for years often lose marks on administrative details and penalty provisions. Study the licence-class material first, then safety and penalties, and use practice questions to find gaps rather than to memorise answers.
What happens if I fail - can I retake it?
Retake rules, waiting periods and any fees are set by SGI and are not stated in the source material used for this page, so we do not publish a figure. Check SGI's knowledge test page or ask at a motor licence issuer before you write, and plan your study so a retake is not needed.
How long should I study before writing?
There is no official study duration. A practical approach is to read the licence-class and road-test material once, then work domain by domain through practice questions, spending extra time on whichever of the four areas you score lowest. Spread sessions over a couple of weeks rather than cramming, and revisit missed topics the day before.
What are the most common ways candidates lose marks?
The recurring weak spots are administrative detail - which class covers which vehicle, what registration and online services do - and penalty and carrier rules, which many drivers assume they already know. Safety questions set in winter conditions also trip people up. If a practice question surprises you, go back to the SGI source page rather than memorising our wording.
Does the knowledge test replace the road test?
No. The knowledge test and the road test are separate stages, and passing the written portion does not license you to drive commercially. The practical assessment evaluates your driving itself. Treat them as two milestones and prepare for the knowledge test with the road test in mind, since the material overlaps.
Where do I book tests and manage my licence online?
SGI provides online services, including a MySGI account, plus tools such as a VIN search and plate calculator, and a locations finder for offices. Use those official channels for booking, payment and account changes. This page only helps you study and cannot book, change or look up anything on your file.
Is this page an official SGI product?
No. This is an independent study resource with original practice material. It is not affiliated with or endorsed by SGI or the Government of Saskatchewan, and it does not reproduce any official question bank. Always confirm rules, fees and procedures on SGI's own pages, which take precedence over anything here.
