You are on a rural part of Interstate 94 in North Dakota. No speed limit sign is in view, and the road is dry. Under current state law, what is the highest speed that is presumed lawful?
Correct answer: 80 mph
Why
A 2025 law raised the interstate limit from 75 mph to 80 mph, effective August 1, 2025. Paved, divided multilane highways that are not interstates keep a 70 mph limit. The basic speed rule still applies, so slow down for snow, ice, wind, heavy traffic or poor visibility.
