During its 2012 session the Florida Legislature amended the text of Florida Statute 322.04 to add a requirement for nonresidents. International visitors would be required to have in their possession not only a valid drivers' license, but also an International Driving Permit (IDP) that translated into English the personal identification information of the driver. The change took effect January 1, 2013, but even before that date, Florida faced allegations that it was violating international law with this new requirement.
