The United States offers some of the world's most iconic road trip experiences — from the Pacific Coast Highway to Route 66, and from the Florida Keys to the vast open roads of the American West. For international visitors, understanding US driving requirements is essential for a smooth trip.
Do You Need an International Driving Permit in the USA?
It depends on your state of visit. The USA does not have a single federal law regarding IDPs — each state sets its own requirements. However, most states strongly recommend or require foreign visitors to carry an IDP alongside their domestic license.
States that explicitly require an IDP for foreign drivers include:
- Georgia
- Kentucky
- New Hampshire
- Some municipalities within other states
Even in states where an IDP isn't strictly required, having one is highly recommended because:
- Car rental companies often require it, especially for non-English licenses
- Police officers may not be familiar with foreign licenses
- It serves as a recognized translation of your license into English
- It helps with insurance claims in case of an accident
