7 Common G2 Test Mistakes That Cause Instant Failure (And How to Avoid Them)

Don't let simple mistakes ruin your G2 road test. With Ontario's G2 pass rate at just 53%, understanding what causes most failures can be the difference between getting your license and waiting months for another chance.

Here are the 7 most common mistakes that cause instant failure—and exactly how to avoid them.

1. Rolling Through Stop Signs (35% of Failures)

The Mistake:

Coming to a "rolling stop" instead of a complete stop at stop signs, red lights, or pedestrian crosswalks.

What Examiners Look For:

• Complete cessation of forward movement
• Stopping before the stop line or crosswalk
• Counting "1-Mississippi, 2-Mississippi" before proceeding
• Looking left, right, and left again

How to Avoid It:

• Practice the "Rock Test": Your car should rock slightly backward when you stop completely
• Use the 3-Second Rule: Count to three after stopping before moving
• Stop Behind Lines: Always stop before crosswalks and stop lines, not on them

Pro Tip: Even if traffic is flowing, you MUST come to a complete stop at stop signs.

2. Forgetting Shoulder Checks (28% of Failures)

The Mistake:

Failing to physically turn your head to check blind spots before:

• Changing lanes
• Merging
• Parallel parking
• Backing up
• Pulling away from curb

What Examiners Look For:

• Obvious head movement (not just eyes)
• Checking before AND during maneuvers
• Looking over the correct shoulder
• Timing checks appropriately

How to Avoid It:

• Exaggerate Head Movement: Make it obvious you're checking
• Mirror-Signal-Shoulder Check: Follow this sequence religiously
• Check Multiple Times: Once before signaling, once before moving

Remember: Mirror checks alone are NOT sufficient—you must turn your head.

3. Improper Lane Changes (22% of Failures)

The Mistake:

• Changing lanes without signaling
• Cutting off other vehicles
• Not checking blind spots
• Signaling but not actually changing lanes when safe

What Examiners Look For:

• Signal at least 30 meters before changing
• Adequate spacing (3-second gap minimum)
• Smooth, confident lane changes
• Proper positioning in new lane

How to Avoid It:

• Use the 5-Step Process:

  1. Check rearview mirror
  2. Signal your intention
  3. Check side mirror
  4. Shoulder check
  5. Change lanes smoothly

• Practice Timing: Signal early, but don't change until it's safe

4. Speed Control Issues (20% of Failures)

The Mistake:

• Driving too slowly (10+ km/h under limit)
• Driving too fast for conditions
• Not adjusting speed in school zones
• Inconsistent speed control

What Examiners Look For:

• Maintaining appropriate speed for conditions
• Smooth acceleration and deceleration
• Recognizing and adjusting for speed zones
• Confidence in speed management

How to Avoid It:

• Know Speed Limits: 50 km/h residential, 40 km/h school zones
• Drive with Traffic Flow: Match surrounding vehicles' speed
• Practice Smooth Control: Avoid sudden speed changes
• Watch for Signs: Reduce speed in school and construction zones

Key Point: Being overly cautious (driving too slowly) can fail you just as easily as speeding.

5. Parallel Parking Problems (18% of Failures)

The Mistake:

• Hitting the curb
• Parking too far from curb (over 30 cm)
• Taking too many attempts
• Blocking traffic during the maneuver

What Examiners Look For:

• Smooth entry into parking space
• Proper distance from curb (15-30 cm)
• Completing maneuver efficiently
• Checking mirrors and blind spots

How to Avoid It:

• Learn Reference Points: Use specific visual markers

• Practice the Sequence:

  1. Pull alongside front car
  2. Reverse until your mirror aligns with their bumper
  3. Turn wheel fully right
  4. Reverse until 45-degree angle
  5. Straighten wheel and continue backing
  6. Turn wheel left to straighten

• Practice in Real Conditions: Use actual parked cars, not just cones

6. Poor Intersection Habits (15% of Failures)

The Mistake:

• Entering intersection on yellow/red lights
• Not yielding right-of-way properly
• Stopping in intersection during traffic
• Confusion at 4-way stops

What Examiners Look For:

• Stopping before intersection on yellow (if safe to do so)
• Proper right-of-way understanding
• Clear intersection protocol
• Confident decision-making

How to Avoid It:

• Yellow Light Rule: If you can stop safely, you must stop

• Right-of-Way Priority:

  1. Emergency vehicles
  2. Pedestrians in crosswalks
  3. Right-turning traffic (from left)
  4. Straight-through traffic

• 4-Way Stop Protocol: First to stop, first to go; if simultaneous, right vehicle has right-of-way

7. Inadequate Observation (12% of Failures)

The Mistake:

• Not checking mirrors frequently enough
• Missing pedestrians or cyclists
• Poor scanning of surroundings
• Not noticing important road signs

What Examiners Look For:

• Regular mirror checks (every 5-8 seconds)
• Scanning intersections before entering
• Awareness of pedestrians and cyclists
• Recognition of road signs and markings

How to Avoid It:

• Develop Scanning Habits: Constantly move eyes to check surroundings
• Use the Commentary Method: Mentally narrate what you see
• Check Mirrors Religiously: Before any maneuver and regularly while driving
• Practice Situational Awareness: Look for potential hazards constantly

Bonus Mistakes That Hurt Your Score

Minor But Common Errors:

• Hand positioning: Keep hands at 9 and 3 o'clock
• Seat adjustment: Adjust before starting, not during test
• Signal cancellation: Turn off signals after completing turns
• Following distance: Maintain 3-second gap minimum

Pre-Test Checklist to Avoid Failures

Before You Start:

• [ ] Adjust seat, mirrors, and steering wheel
• [ ] Fasten seatbelt
• [ ] Turn off mobile phone
• [ ] Ask questions if unclear about instructions

During the Test:

• [ ] Come to complete stops
• [ ] Check blind spots before every maneuver
• [ ] Signal early and appropriately
• [ ] Maintain proper speed
• [ ] Stay calm and confident

Mental Preparation:

• [ ] Get good night's sleep
• [ ] Eat light meal beforehand
• [ ] Arrive 30 minutes early
• [ ] Practice relaxation breathing

What to Do If You Make a Mistake

Stay Calm:

• One mistake doesn't automatically mean failure
• Acknowledge the error mentally and move on
• Don't let it affect the rest of your driving
• Focus on executing remaining maneuvers perfectly

Recovery Strategies:

• If you roll through a stop sign, make extra-sure stops for the rest of the test
• If you forget a shoulder check, be more obvious with remaining checks
• If you have speed issues, focus on smooth, appropriate speed control

Test Day Success Formula

The Night Before:

• Review these common mistakes
• Get adequate sleep (7-8 hours)
• Prepare all documents and test requirements

Test Day Morning:

• Light breakfast with protein
• Arrive early to settle nerves
• Do practice maneuvers in parking lot if possible

During Test:

• Listen carefully to examiner instructions
• Drive slightly more cautiously than normal
• Make your safety checks obvious
• Stay confident and positive

Why These Mistakes Happen

Root Causes:

• Nerves: Test anxiety leads to forgetting basics
• Overconfidence: Assuming you don't need to practice fundamentals
• Bad Habits: Practicing incorrect techniques
• Inadequate Preparation: Not understanding what examiners look for

The Solution:

Practice these specific skills until they become automatic, so nerves won't derail your performance.

Final Success Tip

The key to avoiding these mistakes is consistent practice with purpose. Don't just drive—practice the specific skills that examiners evaluate.
