I have a valid Florida drivers licence. Took the test at the DMV and drive round the block and reversed into a parking space!
Years ago that's just what I did I walked into the Driver Licence centre in Daytona Beach and left 40 minutes later with my plastic FL licence.
Tried to do the same thing last year at the office near our vacation home over near Lakeland and got told all I could have was a licence that was valid until the date of my current US stay was up, and I would have to renew again on each visit, at $75.00 a pop I declined.
I wondered if I just had a jobs worth member of staff at the Lakeland office, so tried another office in a nearby town, and hit the same brick wall....
I may print off 3db link and go wave that at them when I go back next month, it would certainly make things easier for me with a Florida licence as far as motor insurance premium.
As far as flying and my FAA class 3 medical goes I only renewed last July so I'm good until end of July 2015
