About speed limits in North Dakota
North Dakota's interstate speed limit rose from 75 to 80 mph on August 1, 2025, after Governor Kelly Armstrong signed House Bill 1298 that May. It was the state's first interstate increase in more than two decades, following the 2003 move from 70 to 75 mph, and it applies to rural I-29 and I-94, with lower posted limits through Fargo, Bismarck and other cities. Away from the interstates, paved divided multilane highways carry a 70 mph limit, paved two-lane highways run 65 mph where posted, and gravel roads default to 55 mph.
The same 2025 law overhauled North Dakota's speeding fines, which had long been among the very cheapest in the nation, with some interstate overages costing only a few dollars. Fines on interstates and divided highways are now the greater of 20 dollars or 5 dollars per mph over the limit, with an extra 20 dollars added for going more than 15 mph over, and the bill also adjusted license-point penalties. The change was pitched as pairing a higher limit with meaningful deterrence.
Urban defaults are 25 mph in business districts, residential neighborhoods and public parks, and school zones drop to 20 mph during opening, recess and closing hours. Cities post their own limits on arterials, and rural highway limits step down through posted transitions as you approach towns.
North Dakota does not operate speed cameras: the state has no enabling legislation for automated enforcement, so no photo-speed or red-light programs exist. Enforcement is handled by the Highway Patrol and local police, and the 2025 fine restructuring, not cameras, is the state's recent lever for changing driver behavior.
Enforcement
The North Dakota Highway Patrol enforces with radar and aircraft-assisted details on I-29 and I-94, and there is no automated camera enforcement anywhere in the state. Winter weather enforcement emphasizes the basic rule that speed must fit conditions.
Tolerance
Historically the tiny per-mph fines made small overages a very low enforcement priority, and a few mph over rarely drew a stop. With the 2025 fine increases, expect tighter attention, especially at 15 or more mph over where the surcharge kicks in.
Speeding fines in North Dakota
Since August 2025, interstate and divided-highway fines are the greater of 20 dollars or 5 dollars for each mph over, plus an additional 20 dollars when more than 15 mph over. That replaced a schedule so lenient that minor interstate speeding could cost under 10 dollars. Serious overages also carry license points, and care-required violations can be cited below the posted limit in bad weather.
