Section 1
Most Common G1 Test Mistakes
The G1 knowledge test is computer-based — 40 questions, 80% required to pass both sections. These are the topics that trip up the most candidates.
Did you know? The G1 test has two separate sections: road signs (20 questions) and rules of the road (20 questions). You must score at least 16/20 on each section — passing one doesn't carry over if you fail the other.
Confusing regulatory and warning signs
Red-bordered signs are regulatory (you must obey). Yellow diamond signs are warnings. Mixing these up is the most common G1 error.
Misreading speed limit signs in school zones
School zones drop to 40 km/h when children are present. Many candidates forget the "when children are present" condition.
Getting right-of-way rules wrong at 4-way stops
The order is: first to arrive goes first. Ties go to the driver on the right. Left-turning vehicles yield to oncoming traffic.
Forgetting G1 licence restrictions
G1 drivers must have a fully licensed driver (4+ years) in the front seat, zero BAC, and cannot drive on 400-series highways or high-speed expressways without a licensed instructor.
Misidentifying construction zone signs
Orange signs indicate construction zones. Fines double in construction zones when workers are present. Many candidates miss the "workers present" nuance.
Not knowing demerit point values
Questions about how many demerit points a specific offence carries are common. Stunt driving (6 pts), careless driving (6 pts), speeding 30–49 km/h over (4 pts).
The G1 test is taken on a computer at a DriveTest centre. You cannot use notes or your phone. The best preparation is taking multiple practice tests until you consistently score 90%+.
Section 2
Most Common G2 Road Test Mistakes
The G2 road test is about 20–30 minutes of city driving. These are the faults examiners record most often — and the ones that cause the most failures.
Serious faults = automatic fail. One serious fault ends your test immediately, regardless of how well you drove before it. Rolling stops and missing shoulder checks are the two most common automatic fails.
Rolling stops at stop signs
Serious FaultThe single most common reason people fail the G2 test. Your wheels must come to a complete, full stop before the stop line. Even a slow roll is an immediate fail.
Missing shoulder checks before lane changes
Serious FaultMirrors have blind spots. Before every lane change, you must physically turn your head and check the blind spot. Examiners watch your head movement closely.
Driving too slowly or hesitating
Minor FaultGoing significantly under the speed limit or hesitating excessively when it's your turn to go shows lack of confidence and is marked as a fault.
Improper lane positioning during turns
Minor FaultLeft turns must start and end in the left lane. Right turns must start and end in the right lane. Drifting into the wrong lane after a turn is a common fault.
Parallel parking too far from the curb
Minor FaultYou must park within 30 cm (about 12 inches) of the curb. Parking farther than 30 cm is a fault. Hitting the curb hard is also a fault.
Not checking mirrors frequently enough
Minor FaultExaminers watch your eyes and head movement. You should be scanning mirrors every 5–8 seconds. Staring straight ahead is a clear fault.
Forgetting to signal
Minor FaultSignal every turn and lane change — even when no other vehicles are visible. Forgetting to signal, or cancelling it too early, is marked as a fault.
Improper following distance
Minor FaultMaintain at least 2–3 seconds of following distance in normal conditions. Tailgating is a fault. Examiners also watch for abrupt braking caused by following too closely.
Did you know? Examiners are trained to observe your eye and head movement. A shoulder check where you barely tilt your head is not enough — turn your head clearly so the examiner can see you checked the blind spot.
Section 3
Most Common G Road Test Mistakes
The G test adds highway driving to the evaluation. Most G test failures come from highway-specific errors — not the city driving portion.
The G test examiner will direct you onto a 400-series highway or expressway. You must demonstrate safe merging, proper following distance, lane discipline, and a clean exit. Practice the highway route near your DriveTest centre before test day.
Poor highway merging technique
Serious FaultMerging too slowly, stopping on the on-ramp, or failing to match highway speed before merging are all serious faults. You must accelerate to highway speed in the acceleration lane.
Not maintaining proper highway following distance
Minor FaultAt highway speeds, you need at least 3–4 seconds of following distance. Many G test candidates revert to city-driving habits on the highway.
Improper lane changes on the highway
Serious FaultMissing shoulder checks, not signalling early enough, or cutting off other vehicles during highway lane changes are serious faults.
Failing to keep right except to pass
Minor FaultOn Ontario highways, you must keep right except when passing. Cruising in the left lane is a fault — and a real-world offence under the Highway Traffic Act.
Incorrect highway exit technique
Minor FaultMove to the right lane well before the exit. Signal early. Reduce speed on the off-ramp — not before it. Many candidates brake on the highway before the off-ramp.
Reverting to nervous driving habits
Minor FaultGripping the wheel too tightly, over-checking mirrors, or making jerky steering corrections signals nervousness to the examiner and can accumulate minor faults.
Section 4
What Ontario Examiners Look For
Ontario DriveTest examiners follow a standardized evaluation checklist. Understanding what they observe — beyond just "drive safely" — gives you a real advantage.
They watch your eyes, not just your hands
Examiners are trained to observe head and eye movement. Mirror checks, shoulder checks, and intersection scans must be visible. Make your checks obvious — a slight head turn isn't enough.
Smooth and deliberate beats fast and nervous
Examiners prefer a driver who moves smoothly and predictably over one who is fast but jerky. Brake gradually, accelerate steadily, and steer with control.
They note hesitation as a fault
When it's your turn to go at an intersection or merge point, go. Excessive hesitation — waiting when it's clearly safe to proceed — is marked as a fault.
One serious fault = automatic fail
Serious faults (running a stop sign, dangerous lane change, hitting a curb hard) result in an immediate fail regardless of how well the rest of the test goes.
They want you to pass
Examiners are not trying to trick you. They follow a standardized checklist. If you drive safely and follow the rules, you will pass.
Communication matters
If you don't understand an instruction, ask the examiner to repeat it. It's better to ask than to guess and make a dangerous manoeuvre.
Most failed mistake across all tests: Rolling stops at stop signs. Your wheels must be completely still before the stop line. This single mistake fails more Ontario drivers than any other.
Section 5
How to Pass Your Ontario Driving Test First Try
Passing first try isn't luck — it's preparation. These strategies are based on what consistently separates passing candidates from those who need to rebook.
Practice the actual test route
Drive the roads near your DriveTest centre before test day. Know where the stop signs, school zones, and tricky intersections are. Familiarity reduces anxiety.
Exaggerate your checks — make them visible
Mirror checks and shoulder checks must be visible to the examiner. Turn your head clearly. A subtle glance doesn't register. Over-checking is never penalized.
Drive at the speed limit — not under it
Driving 20 km/h under the limit is a fault. Match the posted speed in normal conditions. Slow down appropriately for hazards, but don't creep.
Come to a full stop — every single time
Stop completely at every stop sign and red light before turning. Count to yourself if needed. Rolling stops are the #1 automatic fail.
Signal early and cancel after
Signal at least 30 metres before turning in the city. After completing the manoeuvre, confirm your signal is off. Examiners note both missing signals and forgotten cancellations.
Breathe and focus on one thing at a time
Nervousness causes cascading errors. If you make a mistake, reset mentally and focus on the next manoeuvre. One minor error rarely fails you.
Practice before test day reminder: Take at least 2–3 full practice drives on the actual roads near your DriveTest centre. Familiarity with the route removes one major source of test-day anxiety.

Section 7
Mistakes New Drivers Make in Ontario
Beyond the test itself, these are the habits that get new Ontario drivers into trouble in real-world driving — and that examiners also watch for.
Driving too close to parked cars
Leave at least 1 metre of space from parked cars to avoid dooring incidents.
Forgetting to cancel the signal
After completing a turn or lane change, confirm your signal is off.
Braking too late or too hard
Look further ahead and begin braking gradually well before stop lines.
Underestimating pedestrian right-of-way
Pedestrians have the right-of-way at all marked and unmarked crosswalks. Always yield.
Ignoring roundabout yield rules
Yield to all vehicles already inside the roundabout before entering. Do not stop inside.
Not adjusting speed for conditions
Posted limits are maximums for ideal conditions. Reduce speed in rain, snow, or poor visibility.
Turning from the wrong lane
Left turns from the left lane only. Right turns from the right lane only. Always.
Forgetting to check for cyclists
Before opening your door or turning right, check for cyclists in the bike lane.
