ARE DETECTORS LEGAL?
In Most States YES!
Laser detectors are completely legal in every state when
used in automobiles or light trucks (under 10,000 lbs.).
Similarly, when used in automobiles or light trucks, radar
detectors are legal in almost every state. Exceptions are
Virginia and Washington, D.C., which have local regula-
tions restricting the use of radar receivers in any vehicle.
Concerning trucks over 10,000 lbs., the Federal Highway
Administration (FHwA) issued a regulation, effective
January, 1994 which prohibits radar and laser detector use
in these types of vehicles nationally.
Prior to the FHwA regulation, laws existed in the state of
New York restricting the use of radar detectors in trucks
over 18,000 lbs. and in the state of Illinois in trucks over
26,000 lbs.
