Maximum Range Front
Radar Detector Test
The Maximum range radar detection test was performed on a four mile straight stretch of highway with slightly sloping hills.
It should be noted that case law mandates that an officer must establish a "visual tracking history" on a target vehicle and the distances that an officer can get an accurate reading on a violator as seldom greater then 1/4 of a mile. In fact a New Jersey Superior Court ruling restricted use of laser within a 1000 foot range as the officer cannot able to properly identify the vehicle and substantiate his belief that that the vehicle is speeding.
To be effective, a radar detector should be able to notify the driver of radar use at least four times the distance away (capture area).
The following is the Maximum Front range results from the 2003 Speed Measurement Laboratories testing:
