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, eff e c t i v e
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 cert a i n
f r equencies 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.
C u r re n t l y, the FCC (Federal Communications Commission)
p e rmits 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.

may have electrical noise. Install a filter capacitor (470mfd.
25 volt or larger capacitance value) on the back of the
lighter socket.
P R O B L E M : Audio alerts are not loud enough.
• Cancel Auto Quiet Mode or City Mode.
• Check audio level setting (see page 10 & 11).
