I live in California. I actually got the plates due to having Fibromyalgia years before RSD hit. Out here you also get the tag that hangs from the rear view mirror to take along when you ride with someone who doesn't have the plates.

Also out here if you just get the disabled tags, you pay for them every 6 months (can't remember how much). When you have the plate, you don't pay anything for having disabled plates.
