When Do New Winter Load Restrictions Take Effect?

You can't stop the march of time - or - Mother Nature for that matter! December 8 marks unveiling of new inter truck load limits for Minnesota roads - according to the Minnesota Department of Transportation.

Vehicles will be allowed to operate up to 10 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 prior to increasing any weights on city, county and township routes. The sign erected on the roadway governs the load limit in effect. A winter weight increase 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.

For questions about legal weight/size trucking, call: Minnesota Department of Public Safety - State Patrol - Commercial Vehicle Enforcement; 651-405-6196 (select option 3, option 3)

Have you ever wondered how they base their decisions on when to increase the limit? According to MNDOT:

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. Therefore, the ending date for winter load Increases is variable and drivers must 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.
