North Dakota Truck Speed Limit
No split in North Dakota. Trucks run the same posted limit as cars, and that limit went to 80 on rural I-94 and I-29 on August 1, 2025 (N.D.C.C. 39-09-02). NDDOT kept five stretches at 70 through Dickinson, Jamestown, Valley City, Medora and Grand Forks, so read the sign there. Off the interstate you get 70 on paved divided multilane highways and 65 on paved two-lane posted for it. A governed fleet truck will be the slow vehicle either way.
Some figures on this page are flagged medium confidence. The interstate limit and source are solid, but a specific corridor or penalty should be confirmed with the state DOT before you rely on it.

Truck-specific rules and quirks
- North Dakota went to 80 on I-94 and I-29 outside city limits on August 1, 2025 (N.D.C.C. 39-09-02(1)(i), HB 1298), and trucks run it too because there is no split. NDDOT held five stretches at 70 through Dickinson, Jamestown, Valley City, Medora and Grand Forks, so read the sign on those. Off the interstate the ceiling is 70 on paved divided multilane highways and 65 on paved two-lane where it is posted for that, dropping to 55 on gravel and on unposted county and township two-lane.
