I’m going to take a road trip through Montana. In the past, I’ve had a bit of a lead foot, so I want to be aware of the speed limit before I arrive. What is the speed limit in Montana?
speed limit is a maximum of 80 mph—however, this speed limit only pertains to rural stretches of the interstate. Urban stretches of the interstate, such as those found in Billings, Great Falls, and Missoula, all have a maximum speed limit of 65 mph on the interstate.
Other Montana speed limits that you should take note of are:
25 mph in residential areas unless otherwise posted
65 mph to 70 mph on two-lane highways
75 mph on rural highways
