Yeah, California LEOs are not going to be cool with that. It would be the same as driving around on a quad on CA streets even with a AZ plate. They wont be happy about it. Ive seen a few CA plated Rhinos on the road on the CA side of Parker, but that was from the few that snuck in under the radar before the DMV figured out what was going on. They see you doing that now, they will take away your CA plate for sure, if no the rhino.
Ken, I do The key to any street registration being legal in another state is the Title if it says "Not for street use" or " Off Highway use only" your done in any state that only recognizes street legal titles! My Title was issued without that phrase on it and is 100% legal (Not including tires), but your still going to get hassled In Kalifornia!
