Ionian Travel Car Hire recommends you supplement your local driver’s license with an International Drivers Permit (IDP) . An IDP is written in 10 languages and serves as an officially recognized translation of your local driver’s license in over 150 participating members of the United Nations. Your IDP should always be accompanied by your valid local driving license. The UN itself does not issue driving permits, but uses authorized travel associations to administer the service. A passport-size booklet is administered verifying that the motorist has a valid driver’s license from his/her their permanent place of residence.
