What is VASCAR?
VASCAR is an acronym for Visual Average Speed Computer and Recorder. VASCAR
is an electronic speed timing device. It is a computer which can measure a
vehicle’s speed by dividing the distance the vehicle traveled by the time it
took it to travel the distance.
Will a radar detector detect
VASCAR emits no detectable signals. It is not a radio frequency device and
therefore does not produce microwave emissions.
Can VASCAR only be used where there are white lines painted on

determined when being followed by a patrol car, passing a patrol car going
the opposite direction or when the vehicle being clocked is following a
Is VASCAR only used for speed enforcement?
No. VASCAR is connected to the odometer module of the patrol car and
therefore can be used to accurately measure various distances such as those
at an accident scene. VASCAR can also be used to determine the elapsed time
between one moving vehicle and another to determine if a vehicle is
following too closely.
