North Dakota IFTA Calculator

North Dakota has been transformed by the Bakken oil formation in the western part of the state, and the resulting oilfield service industry now generates as much commercial vehicle activity as the traditional agricultural sector. I-94 runs east-west from Bismarck (the state capital) through Fargo to the Minnesota border. I-29 runs north-south from South Dakota through Fargo to the Canadian border at Pembina. US-2 crosses the northern portion of the state through Minot, which is the primary service city for the Bakken oil patch. State Highway 85 from Williston south to Belfield is the heart of the oil field routing — it carries enormous volumes of water, sand, crude, and equipment trucks.

North Dakota's IFTA rate of $0.230 per gallon is among the lower rates in the northern plains. Minnesota at $0.285 to the east is higher. South Dakota at $0.280 to the south is comparable. Montana at $0.2775 to the west is slightly higher. The state is consistently a good fueling option relative to its neighbors.

Weight enforcement in western North Dakota has been a major issue — the oil field has historically generated overweight violations from water and sand haulers that have severely damaged county and state roads. The NDDOT operates aggressive enforcement programs on SH-85 and the county roads in the Williston basin. Tribal land road use on the Fort Berthold Reservation requires separate permits and coordination with the MHA Nation's tribal highway department.

Standard interstate weight limits are 80,000 lbs. Oil field equipment moves require overweight permits through the NDDOT. Winter in North Dakota is among the most severe in the lower 48 — blizzard conditions can close I-94 for days at a time, and wind chill temperatures below -40°F affect engine starting, air brake performance, and diesel gelling. For IFTA compliance, North Dakota requires careful separation of interstate miles from oil field road miles, as the non-interstate routes in the Bakken often involve private roads and field roads that must still be counted in total IFTA mileage.
