If you’re getting ready to take your G2 road test, you’ve probably heard about “automatic fails.” These are mistakes that end your test early. Instead of letting you finish the route, the examiner will stop the test as soon as one happens.
DriveTest doesn’t publish an official list of automatic fails, but our instructors have prepared enough students for the G2 to know which mistakes come up time and time again.
In this post, we break down the five most common automatic fails on the G2 road test and what you can do to avoid each one.
1. Failing to Yield to a Pedestrian
Ontario’s rules are strict when it comes to pedestrians, and examiners treat any slip-up as a serious safety issue. At pedestrian crossovers and school crossings, you must stop and wait until pedestrians have fully crossed and are back on the sidewalk before you go.
If a pedestrian with right-of-way has to slow down, stop, or step back to avoid your car – you’ve failed to yield to them. Common mistakes include:
- Starting a turn while someone is still crossing the street you’re turning onto
- Driving through a pedestrian crossover while the lights are flashing and someone is waiting at the curb to cross
How to avoid this: On every turn, check the crosswalk before you check for a gap in traffic. Learn to spot pedestrian crossovers by looking for their signs and flashing yellow lights. If you see someone waiting at one, start slowing down early so you’re ready to stop.
2. Rolling Through a Stop Sign
A “rolling stop” happens when you slow down at a stop sign but never fully stop. It’s one of the worst habits to bring into your G2 test, and examiners watch closely to make sure your car comes to a complete stop, with no creeping forward.
Where you stop matters too. If there’s a stop line, you must stop behind it. If there isn’t, stop before the crosswalk or edge of the intersection.
How to avoid this: Start braking early so you can come to a smooth, complete stop in the right place. Once you can feel that the car has stopped moving, count to three in your head before proceeding. The same rule applies when turning right on a red light: come to a full stop first.
3. Speeding in a School Zone
School zones trip up a lot of drivers on the G2 test because the speed limits vary across Ontario. Each municipality sets its own – in Mississauga, for example, residential school zone speed limits are 30 km/h. Some zones only apply during certain hours, while others are in effect all day.
On your G2 test, going over the speed limit in a school zone will almost always end your test on the spot.
How to avoid this: Watch for school zone signs, and read the whole sign, including any times listed. Slow down before you reach the zone so you’re already at the posted speed when you enter it.
4. Hitting the Curb
Your G2 test may include parallel parking, a roadside stop, and a three-point turn – each of which brings you close to the curb.
The Official MTO Driver’s Handbook is specific about what’s expected:
- For a roadside stop, pull over parallel to the curb and no more than about 30 cm away from it
- When parallel parking, don’t hit the curb or touch another vehicle
- During a three-point turn, don’t back into the curb or over the edge of the road
Lightly grazing the curb with your tire will usually cost you a few points, not the whole test. But driving up onto the curb, or hitting it hard, shows the examiner that you’re not fully in control of the car, and that can end your test.
How to avoid this: Slow down while performing any maneuver that brings you close to the curb. If you feel yourself getting too close, stop and adjust. Examiners are much more forgiving of a quick readjustment than a curb strike.
A certified instructor can help you practice these maneuvers until they feel natural.
5. Making an Unsafe Lane Change
Lane changes require you to coordinate a handful of skills at once: checking your mirrors, signalling, using spatial awareness, and controlling your speed.
Common lane change mistakes that can end your test include:
- Moving into the lane without performing a shoulder check
- Moving over so close in front of another car that its driver has to brake
- Changing lanes while crossing through an intersection
And if your examiner ever has to step in to prevent a collision, your test is over.
How to avoid this: Practice the lane change sequence from the MTO Driver’s Handbook (check your mirrors and blind spot while you look for a gap → signal → check your blind spot once more right before you move). Make each shoulder check a clear turn of the head, not just a glance, so your examiner knows you’re doing it.
Summary
The five most common automatic fails on the G2 road test are:
- Failing to yield to a pedestrian
- Rolling through a stop sign
- Speeding in a school zone
- Hitting the curb
- Making an unsafe lane change
Final Thoughts
Your G2 examiner won’t be expecting a perfect drive. They’re looking for proof that you can safely handle real traffic and make good decisions under pressure. Most automatic fails come down to a moment of rushing or lost focus, whether that’s rolling through a stop sign or forgetting a shoulder check while changing lanes. Build solid habits before test day, and these mistakes will be much easier to avoid.
