The arguments against radar detectors are well documented, the most obvious being that users believe they can speed at will and not get caught. Those who actually use radar detectors know that they are anything but a free pass to speed on public roads. In my own great state of Ohio, radar detectors are used to navigate the mine field of speed traps that plague our roadways.
Currently, Virginia and Washington D.C. are the only areas of the U.S. where the use of a radar detector in any vehicle is illegal. New York and Illinois have laws against radar detectors being used in commercial vehicles, while Minnesota and California have laws against hanging anything from a vehicle's windshield, which includes radar detectors.
