The "Reasonable and Prudent" speed limit lasted from 1995 to 1999.
"May 1999: A law passed earlier that year by the Montana Legislature took effect to set a 75 mph speed limit on interstate highways in Montana. It was the state's first posted daytime speed limit since December 1995."
I do not know of any state at the present time which does not have a speed limit.
I recall the "reasonable and prudent" or similar speed limit in Montana when we moved their in 62 and until challenged to the state supreme court seemed to IMHO do well for a limit. At that time truck limit was 55mph. Then the limit was challenged in the state supreme court and ruled to "arbitrary" or similar so for a while the "reasonable and prudent" limit was unenforceable so effectively there was no speed limit.
the state put in the 75 limit on interstate, 70 on many secondary roads. Interestingly the fatality rate with the "reasonable and prudent" or no effective limit for many years was lower than the fatality rate under the 75mph rate, at least in the first few years of 75mph.
During the 70's gas crisis the 55mph limit was only give limited teeth. Fine was minimal, payable on the spot, not a moving violation. I still have a few ticket reciepts stashed away for speed that today would get me a big ticket. Ticket was for "wasting a natural resource" or something similar.
at least till the late 70's under the reasonable and prudent the Nighttime limit was 55 as was the truck limit.
There are sections of interstate in Montana now that have an 80mph limit. sections of I-90 from the base of lookout pass to missoula, most of I-15 between GF and Helena and likely other sections as well. (unless it changed since last March).
But Idaho has one up'd montana with some interstate sections at 85mph now.
