From December 8, 1995 to May 28, 1999 Montana's daytime automobile speed limits were "reasonable and prudent", according to interpretation by Highway Patrol officers. Fines were increased and motorists were advised to drive carefully according to existing weather and road conditions. American speed enthusiasts were delighted and the state's Interstate highways got a reputation as the Montanabahn. Congress was not amused, and neither were many Montana residents. With a little help in potential Federal funding restrictions, speed limits were restored. Montana's maximum speed limit is now 75 MPH on the Interstates - check with Montana DOT for current speed limits, road condtions, etc.
