Legal size & loaded measurements
General width
8′6″Separate allowances apply to qualifying low-bed farm and construction moves; Interstate permit rules still apply.
Loaded height
13′6″Ordinary vehicle-and-load limit; listed exceptions are separate.
Overall length
Minnesota's superload guide defines 150 feet as a superload threshold; other length limits remain configuration and permit specific.
Rear overhang
Minnesota General Provisions and current permit terms govern rear projection and warnings; exact result needs load and route facts.
Gross and axle weight
Minnesota's superload guide defines 250,000 pounds GVW as a superload threshold; registered weight, axle/group, bridge and posting facts remain required.
Axle spacing & bridge limits
Minnesota SUPERLOAD review may require individual axle-line spacing, schematics and manual bridge analysis; GVW alone is insufficient.
Ordinary width & equipment exceptions
General outside width is 102″, excluding qualifying mirrors and limited securement devices. Low-bed trailers or equipment dollies used exclusively for farm machinery or construction equipment have a separate 9′ allowance; widths over 102″ still require a permit on Interstate highways under that exception.
Ordinary loaded height
The ordinary height limit is 13′6″, measured with or without the load. The statute separately addresses double-deck buses; an OSOW permit is required for freight movements exceeding the applicable limit.
Trailer length & rear-axle position
A semitrailer may exceed 48′ up to 53′ when the kingpin-to-center-of-rear-axle-group distance is no more than 43′. The statute includes the rear bumper and load in trailer length. Trailer length and overall combination length are separate measurements.
Permits, routes & larger loads
Roads & authorities
MnDOT Commercial Vehicle Operations administers state permits; county/local road authority approval is required before local-road operation.
Permit products & applications
Minn. Stat. §169.86 authorizes special permits to exceed height, width or load; the permit does not increase registered weight.
Special permit products
MnDOT publishes annual, construction/farm, boat, mobile-home, mobile-crane and other permit products; trip-log preauthorization applies to stated annual cases.
State permit fees
Single-trip agency fee example
$15 for this Minnesota planning example: a nondivisible load measuring 8′7″ wide, 13′ high and 70′ overall, at 72,000 lb gross on a five-axle rig with a 48′ trailer. The example uses 100 in-state miles. Change the load details in the calculator for your move.
What the agency estimate includes
The calculator applies Minnesota's maintained single-trip permit schedule to the loaded vehicle and the supplied fee inputs. It itemizes the supported state charges, including weight or distance charges where applicable. Annual permits, special products, local permissions and payment-method charges need their own applicable schedule.

About the example equipment
The samples use ODPermit’s editable 48 ft flatbed · 5 axles planning profile. Loaded dimensions, gross weight, 100 state miles and Texas registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.
Great Dane Freedom trailer specifications — 48 ft platform; the illustrated 40 in drop deck and 20 in drop support a 60 in upper-deck planning height. Combined tare and tractor geometry are editable ODPermit assumptions.
Pilot cars, height poles & surveys
14′6″-wide load example
Example: 14′6″ wide × 13′ high, 75′ overall, 72,000 lb gross, zero overhang or rear projection, ordinary nondivisible freight in daylight. Depending on the road or permit conditions: If any part of the load extends left of the centerline on an undivided road, a certified lead peace officer and front and rear pilot cars are required.
17′6″-high load example
Example: 9′ wide × 17′6″ high, 75′ overall, 72,000 lb gross, zero overhang or rear projection, ordinary nondivisible freight in daylight. Depending on the road or permit conditions: If any part of the load extends left of the centerline on an undivided road, a certified lead peace officer and front and rear pilot cars are required. MnDOT requires an approved physical route survey before permit issuance above 16 ft high, 20 ft wide, or 175 ft long. Conduct it within 14 days of the permit start date. A moving height-pole vehicle does not replace the survey. Document overhead, lateral and railroad-crossing clearances for the proposed route.
Travel hours & road restrictions
Permit travel conditions
General Provisions require compliance with bridge/road postings and local approvals; route evaluation and manual bridge review remain carrier/agency tasks.
Restricted travel
Movement is prohibited in hazardous weather or road conditions, or when visibility is below 500 feet. Check MnDOT's holiday and road restriction notices for the travel date.
Signs, flags & safety equipment
Safety equipment
Warning lights are required whenever signs are required and must be visible from at least 500 feet; exact pilot-car rules remain statutory/product dependent.
Oversize load signs
Minnesota General Provisions require front/rear oversize signs above 12 feet 6 inches width and/or 95 feet length, visible at least 500 feet and lighted/reflective at night.
What the driver needs
Prepare the driver packet
Carry the issued permit and its route and approval documents. Confirm the accepted paper or electronic format with the issuing office.
Special equipment & permit programs
Special permit programs
SUPERLOAD applications may require schematics, surveys, bridge review, local approvals and carrier coordination; preliminary feasibility is not authorization.
Special vehicle programs
Construction/farm, boat, mobile-home, mobile-crane, annual and SUPERLOAD products have distinct conditions and cannot be substituted.
BEFORE THE TRUCK ROLLS
Turn the estimate
into a permitted move.
Confirm the loaded measurements, carrier details, travel dates and exact pickup and delivery. We can help coordinate permits, escorts and route surveys around those facts.
