What the Ontario G1 test covers and how practice questions help

The Ontario G1 written test is a 40-question multiple-choice exam you take at a ServiceOntario office before you can drive with a supervising driver. The test covers road signs, right-of-way rules, safe driving practices, and Ontario traffic laws. Practice questions let you see the exact format and difficulty level you will face, and they show you which topics need more study before you sit for the real exam.

The actual test draws from the Official Driver's Handbook, which ServiceOntario publishes free online. Practice tests work best when you use them after reading the handbook sections on a topic, not as a shortcut to avoid reading it. You need 16 correct answers (40 percent) to pass, but most people study to reach 80 to 90 percent on practice tests before attempting the real one.

Key Takeaways

  • The G1 test has 40 multiple-choice questions covering signs, right-of-way, speed limits, and Ontario traffic laws, and you must answer at least 16 correctly to pass.
  • Practice questions come from the Official Driver's Handbook, so reading the handbook first makes practice tests more useful than taking them cold.
  • ServiceOntario offers free practice tests on its website; some third-party sites offer them too, but the official version matches the real exam most closely.
  • Common weak areas for test-takers include right-of-way at four-way stops, safe following distance, and the meaning of less common road signs.
  • You can retake the G1 test if you fail, but you must wait at least one week before your next attempt.

Where to find official Ontario G1 practice tests

ServiceOntario publishes a free practice test on its website under the "Getting a Licence" section. This is the closest match to the real exam because it uses the same question bank and format. You can take it as many times as you want, and it gives you when ready feedback on which answers were wrong.

The practice test is available online only — you do not need to read software or create an account. You answer all 40 questions in one sitting, and the test shows your score and which topics you missed. This version is updated when the handbook changes, so it reflects current Ontario traffic laws.

Some third-party websites and mobile apps also offer Ontario G1 practice questions. These can be useful for extra practice, but they may not match the official test format exactly, and some contain outdated or incorrect information. Stick with the ServiceOntario version as your primary study tool.

Common question types and topics on the G1 test

Road signs make up a large portion of the test. You will see images of signs and choose what they mean — for example, a diamond-shaped yellow sign, a red octagon, or a white rectangular sign with specific symbols. The test focuses on signs that appear frequently in Ontario, not rare ones, so studying the handbook's sign section is more efficient than memorizing every possible sign.

Right-of-way questions are another major category. These ask who goes first at intersections, four-way stops, roundabouts, and when turning left or right. Many test-takers struggle with four-way stops and left turns across oncoming traffic, so those are worth extra practice.

Safe driving practices cover following distance (usually expressed as a two-second rule or a number of car lengths), speed limits in different zones, and what to do in bad weather or at night. Questions about seat belts, child car seats, and distracted driving also appear regularly.

Ontario-specific laws round out the test — for example, the legal blood alcohol limit, the age at which you can drive alone, and penalties for certain violations. These questions test knowledge of the Highway Traffic Act, not judgment, so the handbook is your study source.

How to use practice tests effectively before the real exam

Read the relevant handbook section first, then take a practice test on that topic. If you score below 80 percent, read the section again and retake the practice test. This cycle is more effective than taking a full 40-question practice test before you have studied anything.

When you miss a question, look up the correct answer in the handbook rather than just moving on. Understanding why an answer is wrong teaches you more than knowing the right answer does. For example, if you miss a question about following distance, read the handbook's section on that topic so you understand the rule, not just the answer to that one question.

Once you have studied all the handbook sections, take a full 40-question practice test under test conditions — no phone, no breaks, no looking things up. If you score 80 percent or higher, you are likely ready for the real exam. If you score lower, identify which topics are still weak and study those sections again.

What happens if you fail the G1 test

If you do not pass, you can retake the test, but you must wait at least one week before your next attempt. You pay the test fee again each time you take it. There is no limit to how many times you can retake the test, so failing once does not prevent you from getting your G1.

Between attempts, focus your study on the topics you missed. ServiceOntario does not tell you which specific questions you got wrong on the real test, but you can ask the testing officer which topic areas gave you trouble, and then study those sections of the handbook more carefully.

Differences between practice tests and the real exam

The official practice test and the real exam use the same question bank and format, so they are very similar. The main difference is that the practice test is available anytime online, while the real test is taken in person at a ServiceOntario office on a scheduled appointment.

The real exam is proctored — an officer watches you take it to may support you are not using notes or a phone. The practice test has no such oversight, so if you use it honestly (without looking up answers as you go), it is a fair simulation of the real experience.

Some people find the real test slightly harder because of test-day nerves or because they did not study as thoroughly as they thought. Taking the practice test multiple times and scoring consistently high (85 percent or above) reduces the chance of this happening.

Frequently Asked Questions

Can I use a practice test on my phone during the real G1 exam?

No. You cannot bring any electronic devices, notes, or study materials into the testing room. The officer will ask you to put your phone away before the exam starts. Attempting to use your phone during the test will result in when ready disqualification and may affect your future testing privileges.

How many times can I retake the G1 test if I keep failing?

There is no official limit on retakes. You must wait at least one week between attempts and pay the test fee each time. However, if you fail multiple times, ServiceOntario may require you to take a driver training course before your next attempt, depending on the circumstances.

Are the practice test questions exactly the same as the real exam questions?

The official ServiceOntario practice test draws from the same question bank as the real exam, so you will see very similar questions and the same format. However, the exact questions on your real test date may differ from the ones in the practice test.

What score do I need to pass the G1 test?

You need to answer at least 16 out of 40 questions correctly, which is 40 percent. Most people study to score much higher — 80 to 90 percent — before taking the real test, because scoring at the bare minimum leaves little room for test-day mistakes.

Is the official handbook free, and where do I get it?

Yes. ServiceOntario publishes the Official Driver's Handbook free on its website in PDF format. You can also pick up a printed copy at any ServiceOntario office. The handbook is the primary source for all test content, so reading it thoroughly is the most important part of your study plan.
