Winter truck load increases began Monday, January 4, on unrestricted highways in the north frost zones, according to the Minnesota Department of Transportation.
Vehicles will be allowed to operate up to ten percent over the standard legal maximum loads on unrestricted highways during the winter load increase period. However, trucks must comply with current registration weight laws and not exceed registered gross weight tolerances.
Drivers should check with local agencies before increasing any weights on city, county and township routes. The sign erected on the roadway governs the load limit in effect.
A winter weightincrease permit is required to take advantage of the 10 percent weight increase on interstate highways only; a permit is not required for state trunk highways.

The start and end dates for winter load increases are based on how weather is affecting roadway strength. These dates are established by monitoring roadway strength as weather conditions change. The end date for winter load increases is variable and drivers should check for updates throughout the year.
Vehicle operators are required to check with MnDOT for the exact start and end dates.
All changes are made with a minimum three-day notice.
