G Test Highway Speed Tips Ontario 2026 — Pass the Highway Section
The highway section is where most G test candidates fail. Speed, merging, and lane discipline are all tested. Here's exactly what examiners expect — and how to nail it.
Based on the official Ontario Driver's Handbook and real DriveTest scenarios. Updated October 2026.
Highway Section — Step by Step
Entering the On-Ramp
Accelerate smoothly and progressively. You should be at or near highway speed before the merge point.
Shoulder Check Before Merging
Turn your head to check the blind spot. Do this visibly — examiners watch your head movement.
Match Traffic Speed
Reach 90–100 km/h before merging. Slow merging is the #1 G test highway fail.
Maintain Highway Speed
Once on the highway, maintain the posted limit. Don't drop to 80 km/h in a 100 zone without reason.
Lane Changes
Signal, check mirrors, shoulder check, then move. Do this smoothly and confidently.
Following Distance
Keep a 2-second gap minimum. Count "one-one-thousand, two-one-thousand" from when the car ahead passes a fixed point.
Exiting the Highway
Signal early, move to the right lane, then exit. Don't brake on the highway — brake on the off-ramp.
Critical: Speed is Non-Negotiable
Driving 80 km/h in a 100 km/h zone without reason is a fail. Examiners expect you to drive at highway speed. Confidence on the highway comes from practise — get at least 10 highway hours before your test.
Frequently Asked Questions
What speed do I need to reach on the highway during the G test?
You must reach and maintain the posted speed limit, typically 100 km/h on Ontario 400-series highways. Driving significantly below the limit (e.g., 80 km/h) when traffic allows is a fail.
How fast should I be going when I merge onto the highway?
You should match highway traffic speed before merging — typically 90–100 km/h. Merging too slowly (under 80 km/h) is a critical error.
Do I need to do a shoulder check when merging onto the highway?
Yes. A shoulder check is required before every merge and lane change on the highway. Missing it is a critical error.
What if there is no gap to merge onto the highway?
Use the full length of the acceleration lane to match speed. If no gap exists, it is acceptable to slow down and wait for one — but you must still reach highway speed before merging.
How much following distance is required on the highway?
A minimum 2-second following distance is required. At 100 km/h, this is approximately 55 metres. Increase to 3–4 seconds in poor conditions.
