The free, official MTO Driver’s Handbook is the authoritative study guide for the G1 knowledge test. It’s organized into chapters covering:
- Getting your driver’s licence — the graduated licensing system, testing, and fees.
- Keeping your driver’s licence — demerit points and how convictions affect your record.
- Other ways to lose your licence — suspensions outside the demerit-point system.
- Rules of the road, signs and signals, sharing the road, and safe driving practices.
We summarize the parts most relevant to new drivers on this hub, but the handbook itself is the primary source — read it in full on ontario.ca before your knowledge test.
