The Minnesota Department of Transportation will begin winter load increases on unrestricted highways in the metro, south and southeast frost zones at 12:01 a.m. Monday.

Winter load increases have already begun in the north, north-central and central zones.

Frost zones and restricted routes can be found on the MnDOT load limits map. Start and end dates and other load limit information are shown at mndot.gov/loadlimits.

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.

Check with local agencies (cities, counties and townships) prior to increasing any weights on their 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.

MnDOT will report start and end dates on its 24-hour automated message center at 1-800-723-6543 for the U.S. and Canada, and locally at 651-366-5400 for the Minneapolis/St. Paul area.
