Common G Road Test Mistakes in Ontario
The Ontario G road test (G2 exit test) assesses advanced driving skills, including major-road and expressway driving. The current modified G test at full-time DriveTest Centres focuses on highway merging/exiting, speed and space management, lane changes, turns, curves, intersections, and business-area driving. Parallel parking, roadside stops, three-point turns, and residential-neighbourhood driving are currently excluded from the modified test at full-time centres.
15 Common G Test Mistakes
Merging onto the highway too slowly
One of the biggest problems is entering a highway significantly below the flow of traffic when conditions allow normal acceleration. Use the acceleration lane to build appropriate speed and blend smoothly with highway traffic.
Missing blind-spot checks
Check your blind spot before changing lanes, merging, or making other lateral movements. A mirror check alone does not demonstrate the required observation.
Not checking mirrors frequently enough
On the freeway, the MTO handbook specifically instructs drivers to keep checking surrounding traffic and look in their mirrors approximately every 5–10 seconds.
Driving too slowly on the highway
Driving unnecessarily slowly can interfere with traffic. When conditions permit, maintain an appropriate steady speed while respecting the posted speed limit.
Speeding
Do not exceed the posted speed limit. Watch your speed particularly after merging, travelling downhill, or when the speed limit changes.
Poor following distance
The MTO Level Two road-test guide instructs drivers to maintain at least a two- to three-second following distance on the freeway. Increase your space when conditions require it.
Unsafe lane changes
Use a consistent routine:
Mirror → Signal → Blind Spot → Safe Gap → Change Lane
Make the lane change smoothly rather than moving abruptly.
Poor highway merging
Do not wait until the end of the acceleration lane unnecessarily. Identify a suitable gap early, adjust your speed, check the blind spot and merge smoothly into the nearest freeway lane.
Slowing down before entering the exit lane
A common mistake is braking significantly while still in the freeway's through lane. MTO guidance says not to slow down before you are completely in the exit lane; once there, reduce speed gradually as appropriate.
Forgetting to cancel the signal
After completing a merge, lane change or exit movement, make sure the signal is cancelled when appropriate.
Weak intersection observation
Before entering an intersection, scan left, ahead and right and make sure the path is clear. Pay attention to pedestrians, cyclists and vehicles that have the right-of-way.
Turning into an incorrect lane or swinging wide
Maintain proper lane position through turns. Avoid cutting the corner or unnecessarily drifting into another lane.
Driving in another vehicle's blind spot
Avoid remaining beside another vehicle for an extended period, particularly large trucks. The MTO handbook recommends trying not to drive in other vehicles' blind spots.
Late or missing signals
Signal early enough to communicate your intentions to other road users. Signalling at the same moment you begin moving does not provide useful advance warning.
Poor hazard awareness
Look well beyond the vehicle immediately ahead. On freeway driving, Ontario's handbook recommends looking toward where you'll be in roughly the next 12–15 seconds so you can identify hazards early.
The Most Important G-Test Routine
Remember:
MIRROR → SIGNAL → BLIND SPOT → MOVE
And on the highway:
RAMP → ACCELERATE → MATCH TRAFFIC → CHECK → MERGE
The examiner is looking for a driver who can operate the vehicle safely, legally, smoothly and independently, rather than someone simply performing memorized movements.
Important: Current Ontario G Test Format
At full-time DriveTest Centres, the modified G test currently does not include:
Parallel parking
Three-point turns
Roadside stops
Residential-neighbourhood driving
It continues to test major roads and expressways, merging and exiting, speed and space management, lane changes, turns, curves, intersections and business-area driving. Part-time Travel Point locations continue to offer the standard G road test.
