Driving in the U.S.
Motorists visiting the United States from countries that have ratified the Convention on Road Traffic 1949 (the Convention has been ratified by Ireland), may use their own valid driver licenses to drive in the United States. However, it is recommended that drivers carry an international drivers permit. Visit the AA website. These licenses/permits must be obtained prior to departure for the United States. In particular, visitors who intend to rent an automobile in the United States are advised to obtain an International Driving Permit. These licenses/permits can also be useful in emergencies such as traffic violations or auto accidents.
