In NY anyways, an owner can get the HC plate. My wife, being handicapped, means I can't get that plate. However, what I have been doing for the last decade plus for her is scanning mirror hang and printing it either on mylar clear sheet or large clear packing labels and just sticking it on right side of windshield. For long trips, I leave mirror hang in tourpack in case any police have a problem (never have). Done this all over US and in Canada.
