If you want to drive or rent a car while you stay in lodging and accommodations Miami during your vacation in Miami, foreign tourists are strongly advised to bring a driver's license in Miami that says "international". For some destinations, an international permit is required, but it does not act as a substitute your national driving license. You need both documents.

Generally, if your license is written in Roman script (French, German, etc), the international permit is not required when you are staying in lodging and accommodations Miami. There are some exceptions such as United Arab Emirates, Australia, and South Africa.
If your national license is written in a script image such as in Russian or Chinese, then you must make the necessary arrangements before your departure to obtain an international license (translated) in your country of residence. Get everything resolved for your driver's license Miami before you leave your country so that you may easily drive to and from your lodging and accommodations Miami.
For more information on a driver's license Miami, please check with the consulate in your country.
