About this site

Ontario G1 Prep is a free, independent study tool for the Ontario G1 knowledge test. It is not affiliated with, endorsed by or connected to the Ontario Ministry of Transportation (MTO) or DriveTest.

The study guide summarizes the rules described in the Official MTO Driver’s Handbook in original wording. The sign illustrations are simplified drawings, not official artwork. Always confirm current fees, rules and penalties with official sources, as they change over time.

Your progress, mistakes and bookmarks are stored only in your browser (localStorage) and are never sent anywhere. No account is needed. What the analytics and advertising on the site do collect is set out in the privacy policy.

Languages

The interface, study guide and every question are available in English, French, Simplified Chinese and Traditional Chinese. Switch languages at any time from the menu – your progress is shared across languages.

How the content is checked

Every chapter of the study guide and every practice question is written from the official handbook listed under Official resources, and the passages they rely on are kept with the project. Before a release, a script checks each citation against that archived text, checks every figure in an answer or a study point against the document it cites, and checks that the four language editions agree on every number.

Found a mistake? Email suntech.solutions.contact@gmail.com with the page and, if you can, the passage of the handbook you are comparing it with. Corrections go out with the next release.
