This is from the VH website Driving in Florida Latest update: 15th February 2013 The Florida Department of Highways Safety and Motor Vehicles have been reviewing their recent changes to the requirement of an International Driving Permit (IDP). As a result, they've confirmed that the enforcement of an IDP for UK drivers has been deferred. This means that UK drivers will not be required to purchase and provide an IDP when driving in Florida. Some rental companies continue to uphold this requirement however we can assure you Alamo have confirmed they'll continue to rent vehicles to customers with a UK license and no IDP. Please look here for further information but we'll continue to monitor this situation and will update you as and when we receive further information.
