Maria, where the heck do u live? If u were pulled over in Calif. a cop mite have thot your car was stolen if it wasn't registered to u. And, he mite do the same check on u/it here. Minus the phone call. It would have nothing to do with any "stay at home" rules. Which we don't have because it wouldn't work here anyway!
Since u haven't explained where u live or what the laws r there, how do u expect anyone to give u meaningful advice?
