North Dakota Truck Bans & Hazmat Routes
North Dakota has no cars-only parkways and no hazmat tunnels. The real work is local: Fargo and Bismarck mark truck routes and post weight limits on residential and downtown streets, so a through truck with no stop keeps to the route (NDCC Title 39; city ordinances). Placarded loads run the Interstates; check the NHMRR before you cross a placarded city (49 CFR 397). Watch low rail underpasses in the old grid, and don't trust a car GPS on street weight limits.
A detail here is flagged medium confidence — confirm with the state DOT or the bridge/tunnel authority before you rely on it.
Where North Dakota keeps trucks out
North Dakota has no cars-only parkways and no hazmat tunnels. The real work is local: Fargo and Bismarck mark truck routes and post weight limits on residential and downtown streets, so a through truck with no stop keeps to the route (NDCC Title 39; city ordinances).

Key restrictions
- No parkway or cars-only truck ban anywhere in the state
- Fargo and Bismarck: obey posted truck-route signs and street weight limits
- Low railroad underpasses in older downtown grids, so know your loaded height
- Hazmat runs the Interstates; check the NHMRR for any designated route; no tunnel bans (49 CFR 397)
- Parkway / road ban: No cars-only parkways. Fargo and Bismarck post designated truck routes and weight-limited streets. Stay on the marked route unless you have a local stop.
- Hazmat: No hazmat tunnels or bridge bans. Placarded loads default to the Interstate System, I-29 and I-94, and any state-designated preferred route under 49 CFR 397. North Dakota has few if any designated urban hazmat routes, so placards mostly ride the Interstates; still check the FMCSA National Hazardous Materials Route Registry (NHMRR) before you cross a city with a placard.
- Through-truck routes: Cities set truck routes under home rule. Fargo and Bismarck mark truck routes and post 'No Thru Trucks' with weight limits on some residential and downtown streets. A through truck with no local stop stays on the designated route; a local truck may leave it only for the most direct path to and from its stop.
- Fine: A city truck-route or weight-limit violation is a municipal traffic offense with a modest ordinance fine. There's no parkway-ban fine because there's no parkway ban. Strike a posted low bridge and you own the damage, easily into the thousands, plus the citation.
