North Dakota Truck Weight Limits and Permit Sources

At-a-glance summary

Field-level reference data

North Dakota’s weight review has a specific fine chapter — NDCC Chapter 39-12 — and North Dakota Highway Patrol Motor Carrier Operations as the confirmed enforcement agency. NDDOT handles commercial vehicle permits. North Dakota’s climate and agricultural base mean that the absence of a confirmed statewide seasonal source is somewhat surprising — the state does see spring load restrictions on some roads — but the review didn’t confirm a single statewide official source.

Reading the North Dakota weight table

Weight rows use the federal Interstate baseline and the FHWA state law compilation for North Dakota. I-94 and I-29 carry the main freight volumes. Federal baseline applies on those routes. For US highways and state routes — particularly those serving agricultural operations and oil country routes — verify the FHWA state law compilation and any permit conditions.

North Dakota’s agricultural roads can carry significant axle loads during harvest periods. Local and county road conditions and bridge postings can impose lower effective limits on those routes.

Permit and route authority in North Dakota

NDDOT Commercial Vehicle Permits handles over-limit permits for North Dakota. Applications go through NDDOT’s permit system. North Dakota’s agricultural and energy sectors produce significant oversize and overweight move volumes. Permits cover route, dates, vehicle configuration, and axle weights. Changes to equipment or routing require permit review.

Seasonal, route, and local checks

No statewide frost-law or seasonal weight restriction was confirmed in this review. North Dakota’s climate does produce spring thaw conditions, and seasonal load restrictions are applied on certain roads by local authorities. For moves that use local or county roads during spring, checking with local road departments for current restrictions is the right approach rather than relying on this page’s seasonal field.

Tickets and enforcement notes

North Dakota Highway Patrol Motor Carrier Operations is the confirmed enforcement agency. North Dakota Century Code Chapter 39-12 is the official source reviewed for overweight penalty context. For any citation, the specific NDCC section, excess weight, and court instructions are the controlling documents.

Building a North Dakota source file

A North Dakota dispatch file should include NDDOT permit documentation, current scale ticket, approved route, and the NDCC Chapter 39-12 reference. For Northern Plains corridor planning, the axle weight table, permit office list, seasonal restrictions, and overweight fines pages support multi-state planning.
