Disabled Parking

[gillyflowerz]

I don't know if I'm putting this n the right place!
Here in the UK my husband, who has difficulty walking, has what is called a "Blue Badge" which allows people with disabilities to park on designated areas of the street or some car parks. Is there anything like this in the US, particularly in Louisiana, Mississippi, Tennessee, Georgia and Alabama.?? The badge holds a simple sketch of someone in a wheelchair. Would it be any point us bringing his badge with him on our 6-week road trip?
Many thanks for any help.

NOTE:- I've just seen this thread discussed in 2008/9. There was no definitive answer then but that has helped me a bit.
