North Dakota Truck Speed Limit
No split in North Dakota. Trucks run the same posted limit as cars, which is 75 on most rural interstates and higher on some segments (N.D.C.C. 39-09-02). Read the sign on your route rather than assuming a statewide number, and remember 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.
