10 Common G1 Test Mistakes Ontario Drivers Make (And How to Avoid Them)
Every year, thousands of Ontario drivers fail the G1 knowledge test for the same avoidable reasons — including two commonly missed rules about pedestrian crossovers and highway restrictions. Knowing these mistakes before your test gives you a significant advantage. Here are the 10 most common G1 test mistakes — and exactly what to do instead.

Not Reading the Ontario Driver's Handbook
Why it happens: Every single G1 question comes directly from the handbook. Skipping it and relying only on practice tests means you'll miss nuanced rules.
How to fix it: Read the full handbook at least once before taking any practice tests. Pay special attention to road signs, speed limits, and G1 restrictions.
Confusing Warning Signs and Regulatory Signs
Why it happens: Warning signs (yellow diamond) and regulatory signs (white rectangle or red circle) look different but are easy to mix up under pressure.
How to fix it: Learn sign shapes and colours first. Shape = category. Colour = urgency. A red circle always means prohibition. A yellow diamond always means warning.
Guessing on School Bus and Pedestrian Crossover Rules
Why it happens: Ontario's school bus stop laws and pedestrian crossover rules are specific and frequently tested. Many test-takers guess instead of knowing the exact rule.
How to fix it: Memorize: stop for school buses with flashing red lights in both directions on undivided roads. At pedestrian crossovers, stop and yield even if the pedestrian is on the far side.
Forgetting G1 Licence Restrictions
Why it happens: Questions about G1 restrictions (no driving midnight–5 a.m., zero BAC, accompanying driver requirements) are almost always on the test.
How to fix it: Know all G1 restrictions cold: zero alcohol, no driving midnight–5 a.m., accompanying driver must have 4+ years experience and sit in the front passenger seat.
Misreading Speed Limit Questions
Why it happens: Test questions often ask about default speed limits in specific zones — school zones, construction zones, residential areas, and highways. Many people confuse these.
How to fix it: Default urban speed: 50 km/h. Highways: 100 km/h. School/playground zones: as posted (typically 40 km/h). Construction zones: as posted, fines doubled.
Not Knowing Right-of-Way Rules
Why it happens: Right-of-way at four-way stops, uncontrolled intersections, and when turning left are all tested. These rules have specific answers — not common sense.
How to fix it: At a four-way stop: first to arrive goes first. Tie: vehicle on the right goes first. Turning left: always yield to oncoming traffic going straight.
Rushing Through Questions
Why it happens: The G1 test has no time limit. Many people rush, misread questions, and pick the wrong answer on questions they actually know.
How to fix it: Read every word of each question. Watch for words like "NOT," "EXCEPT," and "ALWAYS" — they change the answer completely.
Skipping the Road Signs Section in Practice
Why it happens: Road signs make up 20 of the 40 G1 questions. Many people focus on rules and neglect signs — then fail the signs section.
How to fix it: Take our dedicated G1 Road Signs Practice Test to focus specifically on signs. You need 16/20 on signs alone to pass.
Not Knowing Pedestrian Crossover Rules
Why it happens: Pedestrian crossovers (marked with orange X signs and overhead flashing lights) have stricter rules than regular crosswalks — and this distinction is tested on the G1 exam.
How to fix it: At a pedestrian crossover, you must stop even if the pedestrian is on the far side of the road — not just when they're in your half. At a regular crosswalk, you stop when the pedestrian is in your half. Know the difference.
Confusing G1 Highway Restrictions
Why it happens: Many G1 drivers (and test-takers) believe that having any G licence holder in the passenger seat allows them to drive on 400-series highways. This is wrong.
How to fix it: G1 holders cannot drive on 400-series highways or high-speed expressways UNLESS accompanied by a licensed driving instructor — not just any G licence holder. This restriction is directly tested on the G1 exam.
Quick Reference: Rules That Are Always Tested
These specific rules appear on almost every G1 test. Memorize them before your exam.
How to Use Practice Tests Effectively
Practice tests are the most powerful tool for G1 preparation — but only if you use them correctly. Here's how to get the most out of them:
Take Full 40-Question Tests
Don't just answer random questions. Take complete 40-question tests that mirror the real exam format — 20 signs + 20 rules. This builds the stamina and focus you'll need on test day.
Review Every Wrong Answer
After each test, go back to every question you got wrong. Don't just note the correct answer — understand WHY it's correct. Read the relevant section of the handbook if needed.
Understand the Reasoning, Not Just the Answer
The G1 test uses different wording than practice tests. If you understand the underlying rule, you can answer any variation. If you just memorized the answer, a differently worded question will trip you up.
Repeat Until Scoring 90%+ Consistently
Keep taking tests until you're scoring 36/40 or higher on every attempt. That buffer protects you against tricky wording and nerves on the real exam. Most people need 3–5 full tests to reach this level.
Your 3-Day G1 Study Plan
Three focused days of preparation is enough for most people to pass the G1 test on their first try.
Read the Handbook + Road Signs
- Read the Ontario Driver's Handbook (free on MTO website) — focus on road signs chapter
- Take our G1 Road Signs Practice Test to identify weak areas
- Review any signs you got wrong
Rules of the Road
- Read the rules of the road chapters in the handbook
- Take our G1 Rules of the Road Practice Test
- Focus on right-of-way, G1 restrictions, highway rules, and speed limits
Full Practice Tests
- Take our full 40-question G1 practice test
- Review every wrong answer and re-read that section of the handbook
- Repeat until scoring 90%+ (36/40) consistently
Conclusion: Know These 10 Mistakes and You'll Pass
The G1 test is very passable with the right preparation. The drivers who fail are almost always the ones who skipped the handbook, didn't take enough practice tests, or didn't know the specific Ontario rules that are directly tested — like pedestrian crossover behaviour and the G1 highway restriction.

Frequently Asked Questions
What is the most common reason people fail the G1 test in Ontario?
The most common reason is failing the road signs section. Many people focus on rules of the road and underestimate how many sign-specific questions appear. You need 16/20 on signs and 16/20 on rules — both sections must be passed independently.
How many times can you retake the G1 test in Ontario?
There is no limit on retakes. You must wait 10 days between attempts and pay the test fee each time. Most people pass within 1–2 attempts with proper preparation.
Is the G1 test hard to pass?
The G1 test is not difficult if you prepare properly. The pass rate improves significantly for people who read the Ontario Driver's Handbook and take at least 3–5 full practice tests before their real exam.
What score do you need to pass the G1 test?
You need to score at least 16 out of 20 (80%) on both the road signs section AND the rules of the road section. Both sections must be passed independently — a high score on one cannot compensate for a low score on the other.
Can you use a dictionary during the G1 test?
Yes. If English is not your first language, you may request a word-for-word dictionary (no definitions) to help with language barriers. Ask DriveTest staff when you arrive.
Can G1 drivers go on 400-series highways?
No — unless accompanied by a licensed driving instructor. A G licence holder in the front passenger seat does not qualify for highway driving. This is a commonly missed rule on the G1 exam.
