Hi I had a Florida driving license but it expired on 9th dec 03 and
because of family commitments will not be able to visit this year. I
know that I can only renew for 6 months ( I have a visa) but is there
a limit between date of last license expiry and date of renewal.In
other words can I renew in march 05 (15 months after my old license
expired)without retaking the test.

I would have to say .. No..

I live in Florida and I let my license expire by 1 week and I had to
retest (the written exam) to renew.

Thanks 
Steve
