America has speed limits for those that drive the highways in every single State in which, these speed limits are supposed to help save lives and therefore make those roads safer to drive upon, which sounds like a theory that makes sense, but speed limits may not always do the task that theoretically they are there to do. For instance, when a speed limit is posted that is lower than what the highway can safely sustain, it is not surprising that you will have a combination of those that do not wish to drive faster than the posted speed limit, against many others that most definitely will driver faster than that limit, because the limit so imposed feels unnatural, so they naturally speed up, creating a clear dynamic between those that insist, in whatever lane that they so desire to drive in, that they need not and will not exceed the speed limit, as compared to those that are driving above the speed limit but having to avoid the danger of other drivers deliberately driving slower than they could or should be.
The highest posted speed limit in America is 85 MPH, but there was a time from December of 1995 through May 1999, in which Montana did not have any posted daytime speed limit on its highways, instead the only caveat being that drivers were instructed to drive at a "reasonable and proper" speed, in which because America likes to collect data, there is plenty of data that was collected, of before and after the time span of "reasonable and proper" being the legal speed as opposed to a finite speed limit. Clearly, those that advocate speed limits would, hands down, just know, even without reviewing the data that not having a posted speed limit would mean more fatalities.
As reported by motorists.org, the last full year in which there was posted speed limits was 1994, in which as reported by the Department of Transportation for Montana there were 111 fatalities in 1994, then in 1995 in which the speed limits were removed in May, the fatality rate for the year actually dropped to 105, and the only year in which there was a meaningful increase in fatalities was 1997 in which there were 140. Examining the data even more closely, motorists.org reported that for the last twelve months of no speed limits for Montana there was a total of 101 fatalities, but the ensuing next twelve months in which the speed limit was re-imposed there were a total of 143 fatalities, greater than any year of which there was no daytime speed limit.
The above statistics are proof positive that the implementation of speed limits which ostensibly are put in place for driver safety, do not always work, signifying that the German autobahn, in which away from urban areas as well as in the absence of inclement weather, there are no posted speed limits, is not stupid nor imprudent. The bottom line is that way too often speed limits are imposed on roads and highways around America in which that limit, does not take into proper account, the conditions of such a road, its true dangers or true safety, the greater visibility of daytime hours, the amount of vehicles that travel such a road at different times of the day, and so on and so forth, because, our governmental officials and agencies don't really care to, which signifies that reducing vehicle accidents and deaths on the roads of America by actually digging down into data and studying such to effect better safety, is not a real priority.
