G Driving Test Mistakes Ontario

Merging Too Slowly or Unsafely

Entering the highway well below traffic speed can make merging difficult. Build speed on the acceleration lane, observe traffic, choose a safe gap, and merge smoothly when conditions allow.

Weak Mirror or Blind-Spot Checks

Observation needs to be consistent before lane changes, merging, exiting, and other changes in road position.

Unsafe Lane Changes

Common issues include signalling too late, choosing a poor gap, drifting between lanes, or changing lanes without a clear blind-spot check.

Poor Speed Management

Driving much slower than traffic without reason, exceeding the limit, or changing speed abruptly can show weak traffic judgment.

Following Too Closely

Maintain enough space to react safely to changing traffic, especially at highway speeds.

Missing Exit Preparation

Identify your exit early, check mirrors and surrounding traffic, signal in time, and move into the exit lane safely.

Focusing on an Unofficial Route

Road-test preparation should focus on transferable skills and safe decisions rather than trying to memorize a route.
