Commercial truck drivers will remain capped at a maximum speed of 105 km/h across Ontario, even as the province rolls out a massive speed limit expansion for passenger vehicles. The Ministry of Transportation confirmed that the newly announced 110 km/h limits, which are expanding across an additional 938 kilometers of 400-series highways this summer, will strictly exclude heavy commercial traffic.
By the end of September, the higher 110 km/h limit will cover nearly 89% of Ontario's highway network, including major stretches of the QEW, Highway 400, and Highway 401. While commuters traveling between Sarnia, Toronto, and Ottawa stand to save up to 30 minutes per trip, transport trucks must legally keep their mechanical speed limiters pinned at the standard 105 km/h.
The policy is designed to maintain strict road safety on North America’s busiest economic corridors, but safety advocates warn the widening speed gap between fast-moving cars and capped trucks could create aggressive lane-weaving. To ensure compliance, the province recently introduced legislation skyrocketing the minimum fine for commercial speed limiter violations from $250 to $1,000.
