The application for a handicapped tag doesn't ask for any vehicle information. I don't think that it even asks for drivers license info-- many that need the tag don't drive at all.
HC tags are recognized in all states no matter what state they are from. They are for the PERSON that they are issued for. If it is hanging from your mirror and you park in a hc spot and that person is not with you then you can be fined. If they are with you but are not getting out of the car then you can't use a HC spot. As long as that person is in the car and leaving the vehicle you are fine.
I am not sure about the concept of only putting a copy of it on your dashboard. I would think that is not legal though. Maybe Sue knows? ETA-- Sue and I were posting at the same time!
There are specific instructions that the tag has to be hanging from your mirror and visible-- or you have to have the license plate with the hc designation on it. I would use the actual tag and keep the copy in my luggage in case of emergency (but not sure it would help anything to have a copy). I really doubt that it would be stolen-- I haven't heard of any cars being broken into in public lots to steal HC tags so the theives can get better parking! I have taken mine in rental cars or family and friend's cars quite often. It is just a matter of remembering it. I keep it in my purse when it is not hanging in the car. Generally I make sure to check the entire rental car for my posessions like sunglasses and any trash so there is really no way I could lose it. And even if you do, you just apply for a replacement-- the DMV has your record of the tag and will just reissue it when you get home.
I would really recommend that you use the original tag. Do you really want to get a huge fine/ticket for illegal parking and have to make a trip back to FL to go to court and plead your case and show your tag to avoid paying it?
For those that are asking about just using their
scooter/wc to get from the regular parking to the park, keep in mind that it can be a long way and you could use a lot of battery power. Then you have the inconvenience of being your power cord and finding somewhere to plug in.
I drove to all the parks 2 years ago and parked in the HC spots. The most inconvenient was the MK/TTC. It is a long walk and as I recall there was an uphill part that was a pain. I can't imagine pusing a wheelchair up that.
DHS has the best HC parking, right across from the entrance, and AK and Epcot don't stand out in my mind so they must have been pretty easy.
