Some of the nation's fastest and slowest roads.
Americans like to talk a fast game, but while we may like to believe we’re always pushing the limits, a new study suggests most drivers stick closer to the speed laws than we might think.
While motorists do run up average speeds over the posted limits in a few states, most stay under the limit, according to data collected though the Speed Profiles database compiled by TeleAtlas, the mapping unit of portable navigation manufacturer TomTom. The report analyzed historical records gathered anonymously, over the last two years, from millions of GPS systems in use on U.S. roadways.
The tattletale systems reveal that the fastest stretch of highway in the U.S. is I-15, running through Utah and Nevada. The average speed is 77.67 mph, but in some unpopulated stretches, the speed limit actually is set at 80.
A Fast Ticket!
On a regional basis, the fastest part of the country isn’t out in the open West but, rather, in the American heartland. TomTom reveals that 7 of the fastest 15 states are Mississippi, Kansas, Iowa, Iaho, Alabama and Missouri, where speeds average just over 67 mph. The big surprise? The typical speed limit in those states is 70.
