I certify traffic radar as part of my job. Every Kustom and Decatur radar out there rounds down to the nearest 1 mph. The circuit measuring the doppler effect is VERY accurate. And in Georgia, the unit itself has to be certified as accurate once a year. In nine years of certifying radars, I have never seen ONE of them inaccurate. I HAVE seen them come in with defects that cause them to have poor range, but have not seen one that is inaccurate.
Even so, a 1 mph ticket? Total bull ****.
Good information to know. I do know the last ticket I had the law allowed the officer to drop the limit by no more than 10mph...according to the cop.
Either way, I've got a number of questions. Not that they will matter regarding the accuracy.
When you test, are these under optimal conditions w/o other automobiles around?
If other cars are around, what is the ratio of errors to good readings?
Is the testing done on a mount, hand held, or both?
If mounted, is it in a car or a platform?
Do environmental conditions (heat/cold) have any bearing on the longevity of accuracy?
How often do these devices get calibrated and how often are they tested for calibration?
Is the line of sight straight and true?
What amount of "surface cover" (if that is the right terminology) is required in order to certify the reading as accurate?
