What Is the Ontario G1 Knowledge Test?

Before anyone is allowed to drive on Ontario’s roads, they have to clear a first hurdle: the G1 knowledge test. It’s the exam that opens the door to your first licence, and for many people it’s the first real contact they ever have with the province’s driving rules.

If you’re wondering what the test actually involves — the format, the topics, who has to write it, and what happens once you pass — this guide walks through all of it in plain language.

The G1 Knowledge Test, in Plain English

The G1 knowledge test is a written exam about driving in Ontario. It covers two things: the road signs you need to recognize and the rules of the road you need to follow.

Passing it is the very first step in Ontario’s graduated licensing system, which moves new drivers through the G1, G2, and full G stages.

Don’t let the word “written” fool you. At most DriveTest centres you’ll take it on a computer touchscreen, not with pencil and paper, and you can choose from more than 20 languages.

The questions are all multiple choice, and each one comes with a set of possible answers to pick from.

The reason Ontario uses a knowledge test before anyone gets behind the wheel is straightforward: driving is a shared activity. Every driver on the road depends on every other driver understanding the same signs and rules.

The test is how the province checks that baseline understanding before handing you a licence.

What the Test Looks Like on the Day

The exam has 40 multiple-choice questions, split into two sections of 20. One section covers road signs — warning signs, regulatory signs, and information signs.

The other covers rules of the road — right-of-way, speed limits, parking, sharing the road with school buses and emergency vehicles, and everyday driving situations.

To pass, you need at least 16 out of 20 correct in each section. This detail catches people off guard: a perfect score on the signs section won’t save you if you only manage 15 on the rules section. Each half of the test has to be passed on its own.

In total, that’s a minimum of 32 correct answers, distributed correctly.

On test day, you show up at a DriveTest centre — appointments generally aren’t required for the knowledge test, so walk-ins are the norm. You’ll need to bring acceptable identification, pass a vision test, and pay the applicable licensing fee.

If you’d like to see how the questions are shaped before you go, trying a free G1 practice test online is the closest thing to sitting in that chair without leaving home.

The Two Sections, Explained

The road signs section tests whether you can look at a sign and know what it means — and what it expects you to do. Warning signs are the yellow, diamond-shaped ones that tell you about curves, intersections, and hazards ahead.

Regulatory signs, often red, white, or black, tell you what the law requires: stop, yield, speed limits, no parking, no U-turns. Information and direction signs are the blue and green ones that point you toward destinations and services.

The rules of the road section covers how you actually behave behind the wheel.

That includes who goes first at intersections, safe following distances, how to pass, what to do when a school bus stops with its red lights flashing, how to react to emergency vehicles with sirens on, and Ontario’s rules around alcohol and drugs.

These are the questions where people most often lose marks, because real-world judgment is harder to guess than a sign shape.

Many learners make the mistake of only studying the signs, since they feel easier to memorize. A smarter approach is to split your study time evenly — the rules section is where marks are hardest to earn back on test day.

Who Actually Has to Write the G1 Test

If you’re 16 or older and have never held a driver’s licence, the G1 knowledge test is mandatory. There’s no way around it: it’s the entry point to Ontario’s graduated licensing system for every new driver.

Newcomers to Ontario aren’t automatically exempt either. Whether you have to write the test depends on where your previous driving experience comes from.

Ontario has licence exchange agreements with a list of jurisdictions, and drivers from those places may be able to exchange their licence without writing a test.

Drivers from countries without an agreement — or whose foreign experience can’t be authenticated — usually start the process from the G1 test like everyone else.

If that might be you, it’s worth confirming your situation directly with DriveTest before you plan your visit.

One thing that surprises people: you don’t need to have taken any driving lessons before writing the knowledge test. Lessons come later, when you’re practicing for the road tests. The G1 test is purely about what you know, not how you drive.

What Happens After You Pass

Passing the knowledge test earns you a G1 licence, and with it, the right to drive — with conditions.

G1 holders must always be accompanied by a fully licensed driver with at least four years of experience, must maintain zero blood alcohol, and face restrictions on when and where they can drive, including the 400-series expressways.

These limits are deliberate: the graduated system is designed to let you build experience in lower-risk conditions first.

After holding your G1 for the required period — usually 12 months, or 8 months if you complete a recognized driver’s education course — you can book the G1 exit road test (the G2 test).

Pass that, and you become a G2 driver with far fewer restrictions. The full G licence follows after one more road test. The whole journey starts, quite literally, with those 40 questions.

How to Prepare Without Wasting Time

The official study source is the Ontario Driver’s Handbook, which covers everything the test can ask. It’s thorough, and it’s free to read online.

That said, most people retain far more by mixing reading with practice questions — testing yourself forces your brain to retrieve information rather than just recognize it.

A practical routine looks like this: read a handbook chapter, then do a batch of practice questions on that topic.

When you can consistently score above the passing threshold on a full-length G1 practice test with 200 questions, you’re working at a level comfortably above what test day demands.

Spreading that over a week or two of short sessions beats one long cram the night before — the test rewards familiarity, not last-minute memorization.

Some learners also like working through a downloadable G1 questions and answers PDF so they can study offline or review on the bus.

Whatever format you pick, the key habit is the same: practice under realistic conditions, review every question you get wrong, and don’t move on until you understand why the right answer is right.

A Few Honest Answers Before You Book

Is the G1 Test Hard?

It’s challenging for people who don’t prepare, and very manageable for people who do. The questions are written in clear language and based entirely on public material — there are no trick questions designed to fail you.

Most failures come from under-studying the rules of the road, not from the test being unfair.

Can I Take the Test in a Language Other Than English?

Yes. The knowledge test is offered in more than 20 languages at most DriveTest centres. Paper versions are available in English and French.

If you want to warm up in another language first, you can try our French G1 practice test alongside the English one.

What If I Fail?

You can retake the test. You’ll need to wait before trying again and pay the test fee for each attempt, so it’s worth arriving properly prepared rather than treating the first sitting as a practice run.

How Long Does the Appointment Take?

Plan for the better part of a morning or afternoon. The test itself is quick for most people, but identification checks, the vision test, and queue time add up.

Do I Need to Study the Handbook Cover to Cover?

You need to know everything the handbook teaches, but you don’t have to learn it only from the handbook. Practice tests, summaries, and targeted review of your weak spots all count as studying — the exam tests your knowledge, not how you acquired it.

The Bottom Line

The Ontario G1 knowledge test is a 40-question, two-section exam that checks whether you understand road signs and rules well enough to start learning to drive.

It’s the mandatory first step for every new driver in the province, taken at a DriveTest centre, and it opens the door to your G1 licence and everything that follows.

Give it the respect it deserves: study both sections evenly, practice with realistic questions until you’re scoring comfortably above the passing mark, and walk in knowing what to expect. Thousands of people pass it every week.

With proper preparation, there’s no reason you won’t be one of them.
