Getting the world of Minnesota Oversize Permits can be complex without the right guidance. For trucking companies hauling loads that exceed legal limits, securing proper permits is not just a formality it's a critical requirement for smooth, safe, and lawful operations. At Unique Trucking Broker, we specialize in issuing all types of trucking oversize permits across Minnesota, making your journey hassle-free and compliant every step of the way.

Why Minnesota Oversize Permits Are Essential

Every trucking operator moving loads beyond Minnesota legal dimensions or weight must obtain valid Minnesota Oversize Permits. These permits authorize vehicles to travel beyond the state’s established size and weight standards and ensure your haul follows state regulations, local restrictions, and safety protocols.

The state requires permits for:

Widths over 8′-6″

Heights over 13′-6″

Lengths over 75′ for combinations or 53′ for semi-trailers

Weights exceeding 80,000 pounds gross

Failure to have the correct Minnesota oversize permits before entering the state can result in fines and delays, making early permit acquisition crucial.

Understanding Permit Validity and Costs

Minnesota oversize permits are valid for five travel days, covering your movement in the state during that period. Planning your routes and timing within this window is essential to stay compliant.

Regarding costs, Minnesota oversize permit cost varies by permit type, load dimensions, weight, and distance. Single trip permits typically start around $15, with additional fees based on mileage or damage assessments for overweight loads. Annual and superloads permits have their own structured pricing based on use frequency and complexity.

Minnesota Critical Operating Times and Travel Restrictions

Understanding operational hours for oversize and overweight loads in Minnesota is vital:

Loads up to 10′ wide can operate from sunrise to sunset without special lighting. They may extend travel hours from 2:00 am to 10:00 pm on weekdays and Saturdays with proper flashing amber lights front and rear for night travel.

Loads over 10′ wide require front and rear escorts, along with lighting, to travel before sunrise or after sunset.

During summer months (Memorial Day weekend through the Friday after Labor Day), no movement is allowed from 2:00 pm Friday until sunrise Saturday, except for certain loads up to 9′ wide on roads 22′ or wider and heights up to 14′. Saturday travel is permitted all day; Sunday travel is limited from sunrise to noon.

No oversize loads may travel on major holidays, selected holiday weekends, and the Fishing Opener Weekend in May.

Special curfews apply in the Twin Cities metro and Duluth for vehicles exceeding 12′-6″ wide, 95′ long, or 14′ high during morning and evening rush hours.

Legal Dimensions and Weight Limits for Minnesota Trucks

Minnesota enforces strict legal dimensions and weight limits that all carriers must adhere to or secure appropriate permits for:

Length:

Maximum 75′ overall length for most vehicles.

Semi-trailers typically 53′.

Kingpin to rear axle (kingpin setting) maximum 43′.

Width: Standard limit 8′-6″ wide.

Height: Maximum 13′-6″ without special permits; special permits allow up to 14′ to 15′-6″ with restrictions and surveys.

Weight:

80,000 lbs gross on designated highways.

73,280 lbs on non-designated highways with 5 axles, and 80,000 lbs with 6 axles.

Detailed axle limits apply: steer axle up to 13,200 lbs (with 11″ tires), tandem 34,000 lbs, tridem 42,000 lbs, single axle 20,000 lbs on designated highways.

Loads exceeding these limits require Super Load permits with additional regulations and routing.

Escort Requirements for Oversize Loads in Minnesota

Escort vehicles are necessary for many oversize movements:

Loads over 95′ in length require one escort; over 110′ need two escorts.

Loads wider than 14′-6″ require one escort on multi-lane highways and two escorts on two-lane roads.

Police escorts are mandatory if the load encroaches on traffic lanes.

Loads taller than 15′-5″ often need escorts with “high poles” to detect obstacles; loads over 15′-6″ require route surveys.

Escort requirements ensure safe passage through varying road conditions, urban areas, and bridges.

Signs, Flags, and Lighting for Safety Compliance

Safety compliance is key for every oversize load:

“Oversize Load” signs are mandatory when escorts are required or the load is wider than 12′. Signs must be illuminated for nighttime travel.

Flags (18″ square) must be displayed at every corner, at overhang tips (if exceeding 4′), and at widest points for loads over 9′ wide or 75′ long.

Flashing amber lights are required during night operations or low visibility conditions.

These measures protect road users, workers, and the load itself.

Minnesota Seasonal Load and Weight Adjustments

Minnesota allows seasonal weight increases to accommodate winter conditions:

Minnesota winter overweight permits grant a 10% increase over legal axle weights, typically effective from December through early spring.

During spring thaw (roughly late February or March through May), weight restrictions tighten to protect infrastructure, with limited travel allowed for overweight loads.

Carriers should consult current seasonal regulations to optimize operations while preserving road safety.
