Sledge,
On a UK licence, you probably have nothing to worry about, as long as you don't get caught driving in Florida again.
I was nabbed in Utah, on an Irish licence, and was given a ticket for $65. I returned home and 'forgot' to pay. Two months later, I moved to Pennsylvania. Another month, still on an Irish licence, I was hit by another car in Philadelphia, and when the police checked me out they found my Utah record. They thought it was funny, and advised me not to go to Utah for a few years!Technically, they could have arrested me!
Ten years on, with an American licence, and I still don't want to drive in Utah. About every six months or so, a letter arrives at my Irish address telling me the fine has gone up because I did not pay. Last letter demanded $4,354.00 + $22.60 postage costs!
Pay the fine..!
