Minnesota Overweight/Oversize Permits
Minnesota oversize permits are valid for five travel days. Drivers must have a permit prior to entering the state.
Sunrise to sunset can run without special lighting. Except for curfew areas and Friday summer restrictions (see below), vehicles up to and including 10′ wide can usually run from 2:00 A.M. to 10:00 P.M. on weekdays and Saturdays. However, they have to flash amber lights front and rear at night, and put lights in place of flags and outline vehicles and loads for night running. Over 10′ wide, must have front and rear escorts as well as lights to run before or after sunrise or sunset.
There is no movement from 2:00 p.m. Friday until sunrise Saturday during the summer months (Memorial Day weekend through the Friday after Labor Day), except for up to 9′ wide on a 22′ or wider roadway, and up to 14′ high. Travel is permitted Saturday all day and Sunday from sunrise to 12:00 noon. Over 10′ wide can travel at night only with front and rear escorts and must meet all lighting requirements.
|Weight:||The gross weight is 80,000 lbs. on designated highways|
Note: Utility Poles are not subject to permits only if the Bill of Lading lists the load as utility poles. Pipes, beams, etc. not exempt.
|Width:||14’6″, and up to 16′ for certain routes|
Note: You must be registered for at least the amount of weight you are permitting for Minnesota.
Loads exceeding these dimensions or weights are considered superloads.
ESCORTS FOR WIDELOAD AND OVERSIZED SHIPPING
When Escorts are Needed:
|Width over 14’6″||Needs 2 escorts on 2-lane highways|
On Multi-Lane Divided Highways:
|Width over 14’6″||Needs 1 escort on multi-lane divided highways|
On All Highways:
|Length over 95′ up to 110′||Needs 1 escort|
|Length over 110″||Needs 2 escorts|
|Height over 15’5″||Needs 1 escort, suggested to also add a high pole, but not required.|
|Height over 15’6″||Must get a height survey to obtain a permit.|
It is the prime responsibility of the permittee to determine the need for police escort, which is automatically required if the permittee is not able to yield right of way to oncoming traffic, if the vehicle/load will encroach into an oncoming traffic lane, or if traffic must be directed or controlled. The permittee is responsible for police escort fees. The state may require police for other safety reasons.
SIGNS, FLAGS & LIGHTS
“Oversize Load” signs are required in Minnesota when escorts are required or when the load is over 12′ wide. They must be lit up to run at night. When the rear overhang exceeds 4′, or the vehicle/load exceeds 9′ in width or 75′ in length, 18-square-inch rear overhang flags are required. Flags should be mounted at the tip of the overhang, at the corners, and the widest points of the load. An overwidth or overlength vehicle/load requires flags at each corner of the load, with an additional flag at the widest point on each side of the load if it extends beyond the corner flags. Overhang exceeding 4′ requires light at night. When the permit is over 12′ wide, flashing amber lights are usually required.
No travel on major holidays, some holiday weekends or on Fishing Opener Weekend in May. For vehicles over 12’6″ wide, over 95′ long, or over 14′ high, no travel in the Twin City Metro area between the hours of 6:00 a.m. – 8:30 a.m. or 3:30 p.m. – 6:00 p.m. or in Duluth city limits between 7:00 a.m. – 8:30 a.m. or 4:00 p.m. – 5:30 p.m. unless specifically stated on the permit. These metro areas are defined on the OD/OW Travel Hours sheet available on their website.
