SGI Class 1 study guide

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. The SGI Class 1 study guide has 4 sections and about 1,523 words.
