STATE PERMIT GUIDE

North Dakota: plan the permit work.

Every field below says what FCC has verified against an official source and what it has not. A field marked Confirmation required is one FCC has not verified — it is not a requirement that does not exist, and it is never a zero.

FCC could not open North Dakota's permit site on 2026-09-20. The North Dakota Highway Patrol is the issuing authority under NDCC 39-12-02. Its permit site served an expired TLS certificate when FCC last checked on 20 September 2026, so a browser will warn before opening it. Phone the Highway Patrol permit office rather than clicking through a security warning. The address is https://www.statepatrol.nd.gov/oversizeoverweight-permit.

Confirmation required

FCC has not verified this against an official source yet, so nothing is published. Confirm the requirement with the North Dakota issuing authority — a blank field is not a requirement that does not exist.

Special / superload review
No published dimensional superload threshold. Overweight single-trip limits are set case by case by NDDOT engineers. Weight points that trigger extra requirements or charges: written verification of liability and property damage insurance is required above 200,000 lb GVW; a graduated permit fee applies above 150,000 lb GVW; a ton/mile fee applies to the portion above 200,000 lb GVW.

Overweight single-trip permits. The 200,000 lb insurance trigger is NDAC 38-06-02-05(2): 'When requesting permits for movements exceeding two hundred thousand pounds [90718 kilograms] gross vehicle weight, or when otherwise required by the highway patrol or department of transportation engineers, the applicant must provide written verification of liability and property damage insurance coverage.'

Lights: between a half hour after sunset and a half hour before sunrise a permitted overwidth vehicle or load needs SAE class 1 lights and reflectors, one rotating or two flashing amber lights above the cab visible front and rear for at least 500 ft, and clearance lights marking the outermost portion beyond 8 ft 6 in. Mirrors: two outside mirrors giving a rear view of at least 200 ft.

When and where to move
Travel hours
Daylight only by default: permits may not be issued for overdimensional movements between one-half hour after sunset and one-half hour before sunrise unless the superintendent authorizes otherwise. By statute, permits for movements not exceeding 12 ft total width, and permits for movements not exceeding 120 ft total length, are valid day and night with proper lighting.

Overdimensional movements. The statutory night-travel allowance is NDCC 39-12-02(5): 'Permits issued for overdimensional movements of vehicles not exceeding twelve feet [3.66 meters] in total width, including load, are valid for travel during the day and night with proper lighting. Permits issued for overdimensional movements of vehicles not exceeding one hundred twenty feet [36.58 meters] in total length, including load, are valid for travel during the day and night with proper lighting.'

Weekend movement
Single-trip permits for overwidth exceeding 16 ft may not be issued authorizing movement on Saturday after 12 noon or all day Sunday. The superintendent may authorize a single-trip permit for weekends.

Seasonal restrictions
Seasonal restrictions are posted, not fixed in rule: the director or authorized employees, and local authorities, may prohibit operation or impose weight restrictions when a highway would be seriously damaged by deterioration, rain, snow or other climatic conditions, and the order takes effect only once signs are erected at each end of the affected portion. Spring-thaw and year-round load-limited highways carry extra ton-mile fees under NDAC 38-06-03-01(6).

Any highway under the director's or a local authority's jurisdiction. The fee rule names the trigger explicitly: 'The ton-mile [907 kilogram-1.6 kilometers] fee for a vehicle or load movement that exceeds the weight limits on highways during the spring thaw or on highways with load limits year-round'. No calendar dates for the spring thaw period are published in these sources. Quoted from the cited document and matched against it on 20 September 2026. Exceptions and permit conditions apply.

Local / toll jurisdictions
The state permit does not cover local roads. The highway patrol and local authorities each issue permits only for highways under their own jurisdiction. A city, county or township that participates in a uniform permit program may not charge additional fees beyond that program, but may issue penalties for violating a posted road restriction and, where a permit is denied, may impose an additional fee or condition in exchange for authorizing the move on its roads.

Jurisdictional split between the highway patrol and local authorities. The fee limitation is 39-12-02(1)(d): 'Notwithstanding any other provision of this chapter, a city, county, or township having control of roads may not impose additional fees for the use of roads beyond the fees established under a uniform permit program.'
