Starting March 1, 2026, Grey County, Ontario, has put weight limits in place on many local roads to prevent damage during the spring thaw. These rules restrict vehicles to five tonnes per axle on designated routes until May 1, 2026.
The seasonal limits help protect road foundations that become soft and weak as the ground shifts and holds more moisture. According to Grey County Transportation Services, heavy trucks can cause permanent damage like deep ruts and cracks during this time of year.
These restrictions affect commercial truck drivers, farmers, and people moving heavy equipment who must now reduce their load sizes to avoid fines. Under Section 122 of the Highway Traffic Act, it is an offence to carry more than five tonnes per axle on roads where reduced load signs are posted.
While the Ontario Trucking Association notes that these rules are standard across the province, drivers should watch for specific signs on county-managed roads. The weight limits will remain in place until the ground is firm enough to handle heavier loads again.
