In NC we are required to notify and I believe it is a good idea no matter where you are located. However I asked a LEO at church about the license or registration being linked to my permit and he told me they aren't. He said they can cal dispatch but nothing comes up on their computer to notify them prior to approaching the vehicle. He said he didn't see why this was imporatant as "the guys with permits aren't the ones you have to worry about" I was glad to hear that response from him!!
