Windsor G road test: expressway tips and what to expect

Updated October 2026

The G road test covers everything from the G2 test plus driving at higher speeds. In Windsor that means a section on the E.C. Row Expressway. Smooth merging, confident lane changes at 100 km/h and clean exits are what make or break this test.

How the test works

Like the G2 test, you start and finish at the DriveTest centre on Dougall Avenue and the examiner gives one instruction at a time. Expect some city driving, a section on the expressway that includes getting on, changing lanes, exiting and coming back, and possibly some of the G2 manoeuvres too. Windsor uses more than one G route, so you won't know which one you'll get.

Merging onto the expressway

Some Windsor entrance ramps curve sharply before they straighten out. Take the curve at the ramp speed, then accelerate firmly once the ramp straightens so you reach traffic speed before you merge.

• Signal left early, as soon as you are on the straight part of the ramp.
• Check your mirror and shoulder check over your left shoulder for a gap.
• Match the speed of traffic and merge into the gap. Don't stop on the ramp unless traffic forces you to.
• Cancel your signal once you're in the lane.

Lane changes at 100 km/h

Keep a steady speed through the whole lane change; slowing down while you move over is a mistake at expressway speed.

1. Check your mirrors.
2. Signal for a few seconds before you move.
3. Shoulder check your blind spot.
4. Move smoothly over, keeping your speed.
5. Cancel your signal.

Exiting safely

Signal for your exit early and slow down on the exit ramp, not on the expressway itself. Some exits have more than one exit lane, and which lane you use matters for what comes next, so listen carefully to the examiner.

Following distance and trucks

Leave at least a two-second gap at expressway speed, and more around trucks. Windsor has heavy commercial traffic heading to and from the border, so a three- to four-second gap behind trucks is safer.

What you get in the DriveTest Routes app

The app covers the parts this guide can't share publicly:

• 3 Windsor G routes used at the Dougall Avenue centre, turn by turn
• Which ramps you join, where you exit, and how each turnaround works
• Which exit lane to use and what to do at the end of each ramp
• Spoken merge, lane-change and exit instructions at the right moments
• The speed limit for every road, ramp and expressway section, with too-fast and too-slow warnings
• Practise as a simulation at home, or follow along in your car with GPS
