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 regulations

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 Illinois in trucks over 26,000 lbs.

Radar Facts

A radar gun operates by transmitting radio waves at certain

frequencies which reflect off objects and are then picked up

by the radar gun’s receiving section. When a radar beam

reflects off a moving target, a measurable frequency shift

occurs. The radar unit converts this shift into miles per hour

to determine your vehicle’s speed.

Currently, the FCC (Federal Communications Commission)

permits operation of traffic radar guns at X Band (10.500 -

10.550 GHz), K Band (24.050 - 24.250 GHz), and Ka Band

(33.400 - 36.000 GHz).

Note: A radar detector will not alarm if an officer is not

transmitting on any one of the above radar bands.
