You don't need an international driving permit to drive in Florida; you just need a valid driver's license, issued in your name, from your state or country of residence. While an International Driving Permit (IDP), while not required, is inexpensive and useful to have for identification purposes, even if you’re not planning to drive. It must be issued in your own country before you depart. Apply through the local or national branch of your automobile association. The application usually requires one or two photos, a current driver license, an additional form of identification and a fee. An IDP does not replace your regular driving licenses; carry both if you are planning to drive. An IDP is valid for one year.
