My doc filled mine in with "Multiple Sclerosis" Leg weakness, fatigue" And that got me the plaque in the mail in less than two weeks. I did not have to go to the DMV at all. Every 2 years, they send me a renewal questionairre which I take to my PCP's office, they fill it out and send it in and I get the new tags in the mail. Seems quite efficient here.

My car was parked in airport Valet parking while we were on this year's MS Cruise and the placquard was missing from the car when we got back. I called the DMV and they asked me to fax them the number of the placquard (on the registration slip they send with it) and I had a replacement tag two days later!
