How Do You Merge onto the Highway for the G Test?

According to the Ontario Ministry of Transportation, the G road test includes a highway driving component that is not part of the G2 test. The examiner will direct you to enter a 400-series highway or a highway with a speed limit of 80 km/h or higher. You will be asked to merge onto the highway, drive in traffic, change lanes, and exit. The highway portion typically lasts 5 to 10 minutes and is designed to evaluate whether you can handle high-speed driving situations safely and confidently.

The proper highway merge technique follows a specific sequence that G test examiners evaluate closely:

DriveTest examiners and driving instructors identify these as the most frequent reasons for failing the highway merge portion of the G test:

According to the Ontario Driver's Handbook, you should be travelling at or near the speed of highway traffic by the time you leave the acceleration lane. On a 400-series highway with a 100 km/h speed limit, this means reaching approximately 100 km/h. Merging at 70 or 80 km/h when traffic is flowing at 100 to 120 km/h creates a dangerous speed differential. On the G test, examiners will note if you are significantly below the flow of traffic during the merge. However, do not exceed the posted speed limit during the test.

Highway merging is a skill that improves dramatically with practice. With a G2 licence, you are legally permitted to drive on all Ontario highways, so take advantage of this before your G test. Start with quieter highways during off-peak hours, then gradually practice during busier traffic periods. SafePass G test preparation lessons include highway driving practice on the routes used by your specific test centre.
