Not every country requires an International Driving Permit — find out where you do, where you don’t, and what to double-check before your trip.
If you're traveling to countries like the UK, Canada, Mexico, or Australia, you're generally allowed to drive with your valid U.S. license for a limited time.
Countries such as Italy, Japan, Greece, and Thailand require an IDP along with your U.S. license. Driving without it can result in fines or even rental denial.
Some nations like France, Germany, or Brazil may require an IDP in certain regions or depending on your stay length. Always double-check to be sure.
