I received a speeding ticket in a rental car in North Carolina on a highway that had two lanes of traffic in one direction and two lanes of traffic in the the. As I was rounding a corner a highway patrol officer travelling in the opposite direction apparently clocked my speed, turned around and pulled me over. I was wondering how the office would know that I was the one speeding when I was simply keeping pace with traffic. Do modern radar guns capture an image of the car that the speed was detected on or something similar that allows the officer to identity my car was the one clocked? I'm not convinced I am guilty or even the right automobile that should have been stopped.
So my question is, is there a legal requirement that these Radar guns (my ticket indicates RADAR was used) to capture the image of the car detected going at that speed, or is this something that can be determined by the officer in medium-heavy traffic (other cars were around me and passing me). Is a possible defense that the office was unable to accurately identity my car as the speeding vehicle?
