Figures compiled by the Iowa Department of Transportation have disappointing news for drivers who’d like to see the speed limit raised on highways in the state. The DOT’s Scott Falb says they prove a faster limit means faster speeders as states that have raised their highway speed limits find drivers will exceed them by the same amount they used to break the old limits. Falb says within a few years, those states have the same number of speeding violations they did before raising their speed limits. Falb’s heard people say “there’s an upper limit somewhere,” but he cites Montana, which once declared the speed limit to be whatever was reasonable and proper and saw drivers going 100 miles an hour, 120 or even 140 MPH, too fast for even unpopulated Montana. The mountain state eventually revised its speed limit to 75 as Falb says when there was no upper limit, and there were some drivers who went to Montana to “air out that car” and drive as fast as they could, since it was allowed. A recent national report for the insurance industry concluded that states that raised speed limits have seen more highway fatalities, and in states like Iowa that kept them the same, the number of highway deaths remained the same or declined.
