States where radar detectors are banned. According to the National Conference of State Legislatures, radar detectors are banned in all vehicles in the state of Virginia and the District of Columbia, Washington D.C.

These prohibitions generally are introduced under the premise that a driver who uses a radar detector will pose a greater risk of accident than a driver who does not.
