I Have a radar detector and have still got tickets Around here they keep radar on stand by ,when detector goes off, and you are speeding and they are locked on to you its to late. They know how and where to set up , so when your detector goes off ,(most ) of the time its to late. IT might save you if he is locked in on the guy next to you. But if you are at a very high rate of speed forget it they are trained to know your speed without a detector . I now use my detector to notice my speed when it goes off, for me i do seem to speed less because when it now goes off and i am not speeding, thats a ticket i did not get. A radar detector can give us a false since of secuity and you are going to get a ticket you can count on it . Good luck to all.
