What Are the Automatic Fails on the G2 Test in Ontario?
Not all errors on the G2 road test are equal. Some mistakes end the test immediately. Others accumulate. Understanding the difference is key to passing on your first attempt.
Based on the official Ontario Driver's Handbook and real DriveTest scenarios. Updated October 2026.
Quick Answer
Ontario does not publish a fixed list of "automatic fails." What ends a G2 test immediately are critical errors and unsafe actions — things like causing a collision, running a red light, failing to yield to a pedestrian, or requiring the examiner to intervene. Accumulating too many minor errors can also result in a failed test, even without a single critical error.
Understanding the G2 Scoring System
The Ontario G2 road test uses a scoring system that distinguishes between different levels of error. The examiner does not simply count mistakes — they assess the type, frequency, and context of each error.
Critical Error / Unsafe Action
Ends the test immediately. Examples: collision, running a red light, failing to yield to a pedestrian, requiring examiner intervention.
Serious Error
A significant lapse in safe driving that may result in failure depending on frequency and context. Examples: repeated failure to shoulder check, consistently poor lane positioning.
Minor Error
A small deviation from ideal driving. One or two minor errors will not fail you. Repeated minor errors in the same category can accumulate into a serious concern.
Actions That End the G2 Test Immediately
The following actions are treated as critical errors or unsafe actions. Any one of them will end your G2 road test on the spot.
Causing a collision
Any contact with another vehicle, a pedestrian, a cyclist, or a fixed object ends the test immediately.
Requiring examiner intervention
If the examiner must grab the steering wheel, apply the brakes, or otherwise physically intervene to prevent a collision, the test is over.
Running a red light
Proceeding through a solid red light is an unsafe action. This includes entering an intersection after the light has turned red.
Failing to yield to a pedestrian
Pedestrians have the right of way at marked and unmarked crosswalks. Failing to yield is a serious safety violation.
Disobeying a stop sign
Rolling through or completely ignoring a stop sign is a critical error. You must come to a complete stop with wheels fully stopped.
Unsafe lane change
Cutting off another vehicle or changing lanes without adequate space or observation can end the test.
Driving the wrong way
Turning into oncoming traffic or proceeding in the wrong direction on a one-way street is an immediate failure.
Errors That Can Accumulate Into a Failure
Many candidates fail the G2 test without making a single critical error. Repeated minor errors in the same category — especially observation and control — can result in a failed test. Common accumulation patterns include:
- Missing shoulder checks on multiple lane changes or turns
- Repeatedly failing to scan intersections before proceeding
- Consistently poor speed control — too slow or too fast for conditions
- Multiple incomplete stops at stop signs
- Repeatedly drifting out of lane position
What the Examiner Is Actually Assessing
The G2 examiner is not looking for perfection. They are assessing whether you can drive safely and independently in everyday traffic. The test covers:
How to Avoid an Immediate Failure
The most reliable way to avoid a critical error is to build consistent habits through practice — not to memorise a list of rules on the day of the test.
- Always come to a complete stop at stop signs — wheels fully stopped, not just slowing down.
- Shoulder check every time before a lane change, turn, or pulling away from the curb.
- Scan intersections left-right-left before proceeding, even on a green light.
- Yield to pedestrians at every crosswalk — marked and unmarked.
- Drive at a reasonable speed — not so slowly that you impede traffic, not so fast that you lose control.

Frequently Asked Questions
Is there an official list of "automatic fails" published by DriveTest Ontario?
DriveTest Ontario does not publish a specific list labelled "automatic fails." What they describe are critical errors and unsafe actions — actions that immediately end the test. These include causing a collision, requiring examiner intervention, running a red light, and similar serious safety violations.
Does stalling the car automatically fail the G2 test?
No. Stalling once is typically recorded as a minor error. Stalling repeatedly, or stalling in a dangerous situation (such as in an intersection), may be treated more seriously. One stall alone will not end your test.
What happens after an immediate test failure?
The examiner will end the road portion of the test and return to the DriveTest centre. You will receive a score sheet explaining what went wrong. You must wait at least 10 days before rebooking.
Can I ask the examiner what I did wrong during the test?
The examiner will not discuss errors during the test. After the test, they will review your score sheet with you and explain the results.
Does going through a yellow light fail the G2 test?
Not automatically. Proceeding through a yellow light is legal if you cannot stop safely. However, speeding up to beat a yellow light — or entering an intersection on a late yellow — may be scored as an error depending on the examiner's assessment.
