I was just wondering how many other states have drunk plates. I always notice at least one car with them on my commute into work. In Minnesota, if you've had a couple of DWI's they can give you different liscence plates for a year or so. If you have those plates, the cops can pull you over for any or no reason and give you a breathalizer-- and you're not allowed to have any alcohol in your system at all or you get in trouble again.
