Minnesota · Oversize & Overweight

Minnesota Oversize & Overweight Permits filed with MnDOT for you, 24/7

In Minnesota, a load over 8 ft 6 in wide, 13 ft 6 in high or 80,000 lbs needs a MnDOT oversize/overweight permit. That permit is not valid on county, municipal or township roads, so the route has to be checked to the last mile. Send us the load and route: our permit desk quotes the price and files every permit the trip needs.

What we check before filing in Minnesota

  1. Does the trip end on a local road?

    A MnDOT permit stops where state roads end. We check the pickup and delivery addresses before filing, so the last miles do not catch you without a permit.

  2. Fishing Opener is a holiday here

    Over 12 ft 6 in wide or 110 ft long, the load parks May 8–10 for the Fishing Opener, and from 2 p.m. the day before each restricted holiday. We check your dates before you promise delivery.

  3. Escorts need a valid certificate

    Minnesota takes its own escort certificate and those of seven other states. We confirm your escorts qualify before the load rolls.

FAQ

Minnesota oversize permit questions

Which dimensions push a load over Minnesota's legal limits?

Over 8 ft 6 in wide, 13 ft 6 in high or 80,000 lbs gross, over 20,000 lbs on a single axle (18,000 lbs on unpaved roads) or 34,000 lbs on a tandem, or over 75 ft for a combination. Any of these needs a MnDOT permit.

How much does a Minnesota oversize permit cost?

It depends on the permit type, size, weight and route, and superloads take a longer review. Put your route into our permit cost calculator for an estimate, or send us the load and our permit desk quotes the exact price before filing.

Is a MnDOT permit good on township and county roads?

No. A MnDOT permit is not valid on county, municipal, township or other local roads, so a route that leaves the state system needs those roads covered separately.

Will an out-of-state escort certificate work in Minnesota?

Only from certain states. Minnesota accepts certificates from Colorado, Florida, North Carolina, Oklahoma, Utah, Virginia and Washington; other escort drivers need a Minnesota certificate.

Is the Fishing Opener a no-travel weekend for wide loads in Minnesota?

Yes. In 2026, May 8–10 is restricted for loads over 12 ft 6 in wide or 110 ft long, along with Memorial Day, Independence Day, Labor Day, Thanksgiving, Christmas and New Year's.

What hours are off-limits to big loads in the Twin Cities and Duluth?

On weekdays, loads over 14 ft 6 in wide or 110 ft long do not move from 6:00 to 8:30 a.m. or from 3:30 to 6:00 p.m. In the seven-county metro, loads over 16 ft wide run only from midnight to 5 a.m., Monday to Friday.
