The US road trip is iconic — Route 66, the Pacific Coast Highway, the Great Smoky Mountains. But the country's driving rules vary by state, and foreign visitors who skip the IDP often face issues at rental counters or in traffic stops. Here's how to do it right.
Do you need an IDP in the USA?
Federal law allows foreign visitors to drive for up to 1 year on a valid foreign licence. However, many individual states (notably Georgia, Florida, parts of Texas) recommend or require an IDP if the licence is not in English. Police and rental staff are far more comfortable with an IDP's standardized multilingual format.
How long is your IDP valid in the USA?
Up to 1 year for non-resident visitors. If you take up residence in any state, you must obtain a state driver's licence within 30-90 days (varies by state).
What documents must you carry while driving?
US law requires drivers to carry their licence at all times. Bring:
- Original domestic driving licence
- International Driving Permit
- Passport with visa or ESTA
- Rental agreement (rentals)
- Proof of insurance (rentals include it; verify coverage limits)
Can you rent a car without an IDP?
You technically can if your licence is in English — but the catch is age and credit. US rental companies:
- Require drivers to be 25+ (under-25 surcharge $25-30/day)
- Require a credit card in the driver's name (debit cards often refused)
- Insist on an IDP for non-English-script licences
Hertz, Enterprise, Avis, Budget, and Alamo all accept foreign licenses; smaller off-airport brands are stricter.

- Texas: Foreign licences accepted up to 90 days for residents.
- New York: No IDP required; tolls cashless (use rental's E-ZPass).
- Nevada / Arizona / Utah (road trip hot spots): Standard rules; watch for desert remoteness — fill up before national parks.
