SPEED MONITORING TECHNOLOGIES

Other Speed Detection Systems

Several techniques other than radar or laser are used to
measure vehicle speeds. When these methods are being
used, no detector can provide a warning. These techniques
include:
• Pacing - A patrol car drives behind you and matches your
driving speed.
• Vascar/Aircraft - The time it takes a vehicle to travel a
known distance is measured.
Radar Detector Detectors (VG-2)
The Interceptor VG-2, or simply VG-2, is a microwave
receiver used by police to detect signals radiated by the local
oscillator of a radar detector. Because its purpose is to
identify persons driving with radar detectors, the VG-2 is
known as a "radar detector detector".
The VG-2 is the primary tool used by the police to identify
radar detector equipped vehicles. If caught, in a state where
detectors are illegal, (see page 21), drivers risk losing their
radar detector and receiving a fine. In addition, instant-on
radar is almost always used in combination with a VG-2,
leaving unsuspecting motorists vulnerable to receiving two
tickets — one potentially for speeding, the other for posses-
sion of a detector.
NOTE: Having a radar detector capable of detecting the
VG-2 may alert you to the presence of a speed trap.
It is the responsibility of the individual radar detector owner
to know and understand the laws in your area regarding the
legality of the use of radar detectors.
