I have it on my automobile. The local alleged "law enforcement" is overtly aware as demonstrated by conversation amongst them recorded on security video when they arrested my son as I drove away in my 'automobile, 'vehicle' is a COMMERICAL term...i am not engaged in commerce, i have a right to travel, there are additional nuances. The lead plain clothes 3 letter agency type is heard to simply say "she's sovereign". They know, educate yourself, start walking in freedom. Read your DOT regs DEFINITIONS and ask yourself if it fitsyou, read both us and your state constitution. How, many 'agencies' in your state have a statutory basis with the accompanying "enabling legislation" or "statutory authorization to make it "law"? They know, educate yourself, start walking in freedom. It is a deeply layered onion to peel, many are operating as business with D-U-N-S #'S under COLOR OF LAW, however as one grasps the concepts, lose your fear, Creator's people shall be "let go" and escape captivity!
