G1 Practice Test: 20 Questions With Answers
These 20 multiple-choice questions, 10 on rules of the road and 10 on road signs, are written in the same style as the G1 knowledge test and based on the Official MTO Driver's Handbook. Aim for at least 16 out of 20, since the real test needs a total score of at least 80%.
How to use this G1 practice test
Answer each question before you read the answer below it. Keep a tally. The real G1 knowledge test needs a total score of at least 80%, so aim for at least 16 out of 20. The real test is also split into sections, such as signs and rules, so make sure neither half of this quiz is a weak spot.
These questions are original and written for practice. Every answer is based on the Official MTO Driver's Handbook, which is where the real test questions come from. For more about the test itself, see the G1 test format.

How did you do?
- 18 to 20: you're in good shape. Keep your edge with a few more practice rounds.
- 16 or 17: you're at the pass line. Review the handbook sections behind the ones you missed.
- 15 or fewer: go back to the handbook before test day. Our Ontario road signs guide and G1 rules guide are good next stops.
Check which half cost you more points. If you missed more sign questions, study shapes and colours. If you missed more rules questions, focus on the numbers: distances, speeds and times.
Keep practising
The Official MTO Driver's Handbook has its own short set of sample knowledge test questions on ontario.ca. Do those too. Then practise with G1 Prep for more practice questions for the G1 knowledge test.
Before you head to DriveTest, read our common G1 test mistakes and check what to bring. After the G1 comes the G2 road test, where Roadity helps with practice routes and spoken turn-by-turn guidance at Ontario DriveTest centres.
Questions
Are these the real G1 test questions?
No. These are original practice questions written in the same multiple-choice style, and every answer is based on the Official MTO Driver's Handbook. The real test questions come from the Ministry of Transportation.
What score should I aim for on a G1 practice test?
The real G1 test needs a total score of at least 80%, so aim for at least 16 out of 20 here. Because the real test is split into sections, try to hit that mark on both signs and rules.
Where can I find official G1 sample questions?
The Official MTO Driver's Handbook on ontario.ca has a short set of sample knowledge test questions with an answer key in its Test yourself section.
How many practice tests should I do before the G1?
There's no official number. A good rule is to keep practising until you're scoring well above 80% on both signs and rules without guessing.
