How Many Mistakes Can You Make on the G2 Test in Ontario?
One of the most common questions before the G2 road test is: how many mistakes am I allowed to make? The honest answer is that there is no fixed number — and understanding why will help you prepare more effectively.
Based on the official Ontario Driver's Handbook and real DriveTest scenarios. Updated October 2026.
Quick Answer
There is no fixed number of mistakes allowed on the Ontario G2 road test. The examiner scores based on the type and frequency of errors — not a simple count. One critical error ends the test immediately. Repeated minor errors in the same category can also result in failure, even without a single critical error.
Why There Is No Magic Number
The G2 road test is not a points-based quiz where you start at 100 and lose points for each mistake. The examiner is making a holistic assessment of your driving ability. Two candidates could make the same number of errors and get different results — because the type and pattern of those errors matters more than the count.
For example: making five different minor errors across five different categories is very different from making the same minor error five times in a row. The latter suggests a consistent unsafe habit.
The Three Levels of Error
Critical Error / Unsafe Action
Result: Immediate test failure
Examples: Collision, running a red light, failing to yield to a pedestrian, requiring examiner intervention.
Serious Error
Result: Likely failure if repeated
Examples: Consistently missing shoulder checks, repeatedly poor lane positioning, multiple incomplete stops.
Minor Error
Result: Recorded but not immediately failing
Examples: Forgetting to cancel a signal, one stall, slightly wide turn, one incomplete mirror check.
What the Examiner Is Looking For
The examiner assesses your driving across several categories. Errors in any of these areas are recorded and weighed:
Observation
Mirror checks, shoulder checks, scanning intersections
Speed Control
Appropriate speed for conditions and posted limits
Lane Positioning
Staying centred, correct lane for turns
Signalling
Signalling in advance, cancelling after turns
Stopping
Complete stops at signs, correct position
Yielding
Pedestrians, cyclists, right-of-way situations
Manoeuvres
Parallel parking, three-point turns, curb stops
Following Distance
Maintaining safe space from the vehicle ahead
How to Prepare Effectively
Because there is no fixed number of allowed errors, the best preparation strategy is to build consistent, safe habits — not to memorise a checklist on the morning of the test.
- Practise shoulder checks on every lane change and turn until they are automatic.
- Come to a complete stop at every stop sign — even in practice.
- Scan intersections left-right-left before proceeding, even on a green light.
- Drive at a reasonable speed — not so slowly that you impede traffic.
- Practise parallel parking and three-point turns until they are consistent.

Frequently Asked Questions
Does DriveTest Ontario publish a maximum number of allowed errors?
No. DriveTest Ontario does not publish a specific maximum number of allowed errors. The scoring system is based on the type and frequency of errors, not a simple count.
What is the difference between a minor error and a serious error on the G2 test?
A minor error is a small deviation from ideal driving — for example, forgetting to cancel your signal after a turn. A serious error is a more significant lapse, such as repeatedly missing shoulder checks or consistently poor lane positioning. Serious errors are more likely to result in failure.
How many minor errors can I make before failing?
There is no set number. The examiner looks at patterns. If you make the same minor error repeatedly — especially in observation or control — it signals a consistent habit rather than a one-off mistake, and that can result in failure.
What is the pass rate for the G2 test in Ontario?
DriveTest Ontario does not publish official pass rate statistics. Driving school estimates suggest that first-attempt pass rates vary significantly by location and level of preparation.
Can I pass the G2 test if I make a mistake on parallel parking?
Yes. Parallel parking errors are scored like other manoeuvres — minor errors are recorded but do not automatically fail you. However, if you cannot complete the manoeuvre at all, or if you hit the curb hard or strike another vehicle, that is a more serious error.
