You passed your G2, you have spent a year or more driving on your own, and now the final step is here: the full G road test. For a lot of Ontario drivers, this one feels more intimidating than the G2, and there is a good reason why. The G test adds the one thing many drivers have quietly avoided since getting their licence, highway driving at full speed.
Here is the reassuring part. The G test is not designed to trick you. It checks whether you can drive safely and confidently in higher-speed traffic, and once you understand exactly what the examiner is looking for and put in some focused highway practice, it is very passable. This guide shows you how.
What Is the Full G Road Test in Ontario?
The full G road test is the final stage of Ontario’s graduated licensing system, and passing it earns you a full, unrestricted G licence. You can book it once you have held your G2 for at least 12 months. The test takes roughly 30 to 40 minutes and, unlike the G2, it includes highway or high-speed driving, so the examiner can see how you merge, change lanes, and manage speed in faster traffic.
The G test evaluates your ability to:
- Merge onto and exit a highway safely
- Change lanes smoothly at higher speeds
- Maintain proper speed and following distance in fast traffic
- Make sound decisions in more complex, higher-speed situations
- Perform a controlled roadside stop
G2 vs. G Test: What Is Actually Different
If you passed your G2, you already know the fundamentals. The G test builds on them rather than replacing them. The headline difference is highway driving: the G2 focuses on city and residential roads, while the G test adds 400-series or high-speed road driving to the mix. Examiners also expect a higher level of polish, since you are now an experienced driver rather than a beginner. For a full side by side, see our post on the G2 vs. G road test differences.
What the Examiner Looks For on the G Test
Understanding the examiner’s checklist takes a lot of the mystery out of the test. Here is what earns and loses points.
Highway and 400-Series Driving
This is the heart of the G test. The examiner wants to see you:
- Merge with confidence. Match the speed of highway traffic on the on-ramp and blend in smoothly rather than stopping or crawling.
- Change lanes properly. Signal, check mirrors and blind spots, and move over smoothly without disrupting traffic.
- Maintain safe speed and spacing. Keep pace with traffic, stay out of others’ blind spots, and leave a proper following distance.
- Exit cleanly. Signal early, move into the exit lane in good time, and adjust your speed for the ramp.
If a 400-series highway is not available near your test centre, the examiner will use the highest-speed road in the area instead, so the skills are the same wherever you test.
The Roadside Stop
The G test includes a controlled roadside stop, where you pull over safely to the side of the road as if parking, then rejoin traffic. The examiner checks that you signal, position the car correctly, and merge back safely.
How to Build Highway Driving Confidence
Highway nerves are the number one reason G test candidates feel unready, and the cure is gradual, structured exposure:
Start on quieter highways or during off-peak hours before tackling the 401 at rush hour.
- Practise merging repeatedly. It is the single most important highway skill, so do it until matching traffic speed feels automatic.
- Get comfortable with lane changes at speed, checking blind spots every time.
- Practise on the roads near your test centre so the environment feels familiar on test day.
- Book lessons with an instructor if highways make you anxious, since a calm coach beside you accelerates your confidence quickly.
Common Mistakes That Fail the G Test
Most G test failures come down to a handful of avoidable errors:
- Hesitant or slow merging that disrupts highway traffic
- Driving too slowly on the highway out of nervousness
- Weak blind spot checks during lane changes
- Following too closely at high speed
- Drifting speed, either creeping over the limit or dropping well under it
- Indecision at merges and exits
Almost all of these trace back to a lack of highway practice, which is exactly the gap to close before test day.
Practise With an Instructor and a Test-Ready Car

Frequently Asked Questions
How long do I have to wait to take the G test?
You must hold your G2 licence for at least 12 months before you can take the full G road test in Ontario. There is no upper limit, so you can book whenever you feel ready after that point.
Does the G test include highway driving?
Yes. The full G test includes highway or high-speed driving so the examiner can assess your merging, lane changes, and speed management. If no 400-series highway is nearby, the highest-speed road available is used instead.
How long is the G road test?
The G road test usually takes about 30 to 40 minutes, longer than the G2, because it covers highway driving in addition to regular roads and manoeuvres.
What happens if I fail the G test?
You keep your G2 licence and can rebook the G test after paying the fee again. Most drivers who fail do so on highway skills, so targeted highway practice before rebooking makes a big difference.
Can I use a rental car for my G test?
Yes. As long as the vehicle is roadworthy and properly insured, you can use a rental. DriveZee offers a road test car rental with a pre-test warm-up so you arrive prepared in a car you are comfortable with.
