Loaded height: 14′
Ordinary vehicle-and-load limit; listed exceptions and actual route clearances apply.
NN semitrailer: 53′
Federal National Network allowance for a tractor with one semitrailer. Longer trailers may qualify under state axle-position and route rules; local roads can differ.
Overall length: No NN cap*
*For a tractor with one compliant semitrailer on the National Network. Other combinations, trailers, projecting loads and local access have separate limits; see the state measurements below.
Interstate weight: 80,000 lb*
*Federal baseline, subject to the bridge formula, registration and postings: 20,000 lb single axle and 34,000 lb tandem. A particular configuration may have a lower limit; state grandfather allowances need verified spacing and route eligibility.
Legal size
Legal limits are 8′6″ wide and 14′ high. Length and weight depend on the setup, axles, spacing, tires, registration, maps, season and route.
Width and height
Legal width is 8′6″ and legal height is 14′. Exceptions depend on the load.
Axle limits with a permit
With a permit: single (4 tires) 24,000 lb, tandem (8 tires) 45,000 lb, triple (12 tires) 60,000 lb, four axles (16 tires) 68,000 lb. Permit maximums include all tolerances. Tire width also limits permit weight: 600 lb per inch on single and tandem axles, 550 lb per inch on groups of three or more.
Legal axle weights off the Interstate
On highways other than the Interstate, legal limits are 20,000 lb on a single axle, 34,000 lb on a tandem and 48,000 lb on a group of three or more axles.

8NDHP Policy 9-15 — Pilot Car Policy (1/2016) · checked Oct 13, 2026What official sources leave open15
Where North Dakota’s official sources disagree or say nothing, confirm with the agency before dispatch.
- No height-pole rule is published; over 18′ high a pilot car leads, but the policies don't say it must carry a pole.
- No published maximum permit width, height or length for general single-trip loads (only manufactured housing, 18′ wide, and the annual permits).
- The Pilot Car Policy sets no certification or training beyond a driver 18 or older with a valid license; no pilot-car reciprocity rule is published.
- Conflict on Highway Patrol escorts over 18′ wide: Policy 9-6 and the Pilot Car Policy say only if the regional commander deems it necessary; the Heavy Load Policy (Annex E, 8/2023) says loads over 200,000 lb that exceed 18′ wide will require an official escort unless the commander exempts them.
- Conflict on whom to contact for a Highway Patrol escort: Policy 9-6 (11/21/2025) says the regional commander(s) in the region(s) the load will travel; the Pilot Car Policy (1/2016) says the regional commander where the load originates.
- Service/routing fee conflict: Policy 9-6 (11/21/2025) lists $10 per single-trip permit; the E-Permits page lists $8 for over-dimensional-only single trips (and $10 for Interstate and 129,000 lb permits); the Heavy Load (8/2023) and Manufactured Housing (08/2023) policies list $8.
- Utility threshold wording differs: Policy 9-6 requires written utility authority for loads exceeding 18′ high; the E-Permits page says 18′ or higher.
- Load diagram thresholds differ by product: Policy 9-6 requires the track width form over 250,000 lb (or non-standard trailers or narrow track); the E-Permits Building/Trunnion section requires a vehicle loading diagram over 200,000 lb or with 8 tires on an axle.
- The NDHP permit page caps tandem axles at 40,000 lb and single axles at 22,000 lb over 150,000 lb gross; Policy 9-6's axle table (24,000 single, 45,000 tandem) doesn't mention that reduction.
- Night travel wording differs: Policy 9-6 allows night moves only at 12′ or less wide and 120′ or less long; the 2026 calendar says loads 12′ or less wide, 120′ or less long or overweight only may travel day or night with proper lighting.
- NDCC 39-12-04(4)(f) exempts tractor-semitrailer combinations on the Interstate and designated federal-aid routes from the state length limits where federal law requires; the 75′/110′ combination limits don't reflect that.
- No route-survey requirement is published; clearances are the permittee's responsibility and written utility authority is required over 18′.
- No statewide metro rush-hour curfew is published; Fargo has its own city policy.
- Only fixed-date 2027 holidays are listed: NDHP has not posted a 2027 calendar (the 2027 calendar URL returned 404), so Memorial Day, Labor Day and Thanksgiving 2027 windows and any observed-day handling (July 4, 2027 falls on a Sunday) are unpublished.
- Paper vs electronic: Policy 9-6, Policy 9-8 and NDCC 39-12-02 accept a legible electronic or paper permit, but the E-Permits page says mobile home and workover rig permits need a paper copy.

The rule in full6 official sources
The permit authority
NDHP permits cover only the state route on the permit. Fargo has its own city policy. Other local, tribal, federal, private and facility roads need their own approval.
Permits
Have a readable paper or electronic permit before entering North Dakota or starting the move. A single trip is one-way within five days. Self-propelled fixed-load vehicles have their own option.
Heavy and extreme loads
Heavy loads, loads over 200,000 lb, nonstandard trailers, narrow-track equipment and extreme sizes go through extra NDHP engineering review. Routine limits alone never allow a move.
Single-trip permit
A single-trip permit covers one vehicle or combination for one one-way move within five days. A self-propelled fixed vehicle may instead make multiple moves within one 24-hour period.
Heavy Load permit
Loads over 200,000 lb need NDDOT bridge engineer and district engineer approval before the permit is issued. Apply 1 to 15 days ahead unless there is an emergency. Include a statement that the load's weight can't be reduced and no other way to move it is available.
Heavy Load fees
Heavy Load permits carry a ton-mile fee plus other charges: $.05 per ton per mile on the gross weight above 200,000 lb. $8 service/routing fee per permit. $25 engineering fee per application when extra analysis is needed.
150,000–175,000 lb
Over 150,000 lb up to 175,000 lb, loads must be reasonably reduced, and moves need district engineer approval unless they use pre-approved routes within the set weight limits.
Permit limits for 4+ axle groups
On a permit, axle groups of four or more may carry no more than 19,000 lb per axle; a five-axle group is capped at 85,000 lb and a six-axle group at 102,000 lb.
Spring and heat limits
Overweight permits aren't issued during spring road restrictions, or on highways with other road restrictions, except under the Road Restriction Permit Policy (9-17) or in a declared emergency.
County, township and city roads
The Highway Patrol and local authorities each issue permits only for highways under their own jurisdiction, so county, township and city roads need the local authority's permit.

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 North Dakota registration are example inputs, not a capacity rating or a route approval. Replace them with your actual setup.
Great Dane Freedom flatbed brochure — Drop-deck option: 20–26 in drop from the upper deck with a 40–34 in rear deck height, which gives the 60 in upper-deck planning height. Platform length, combined tare and tractor geometry are editable ODPermit assumptions.

We summarize official sources as of the dates shown, but rules change often and a summary can be incomplete or out of date. Only a permit issued by the state or local agency authorizes an oversize or overweight move, and that permit and the agency’s current rules control. Confirm limits, escorts, routes and travel times with the issuing agency before you move a load.
