I am couldn't really find a more appropriate thread to post this in so I hope it is okay. I've had my passport radar detector for a while now and really don't do as much traveling on I-76 as I use to. I usually unplug my detector when I am not on any highway or interstate because I was told that only state troopers are allowed to use radar guns. I've tried to google it and can't really get a direct answer. So the question is, can only state troopers use radar guns or can any township police department use radar guns as well? There's too many false alarms to have it plugged in while driving around town due to automatic doors and newer cars with lane departure sensors.
