An International Driving Permit is not required in most countries, but it is required in some, and carrying one protects you in places where it is optional

Whether you need an International Driving Permit (IDP) depends on three things: which country you are visiting, which country issued your license, and whether you are renting a car or driving your own vehicle. Many countries accept a valid U.S. driver's license alone. Others legally require an IDP alongside your home license. Some car rental companies demand an IDP even when the country does not. The safest approach is to carry both your home license and an IDP if you are driving outside your home country for more than a few days.

An IDP is a translation and verification document issued by your home country's motor vehicle authority. It is not a separate license and does not replace your home license. It is valid for one or three years depending on which version you obtain, and it costs between $15 and $30 in most U.S. states. The document exists because some countries do not trust foreign-language documents or want a standardized format they can read quickly at a traffic stop.

Key Takeaways

  • An IDP is legally required in some countries (including France, Germany, Italy, Spain, and most of South America) and optional but recommended in others.
  • Your U.S. driver's license alone is often accepted in English-speaking countries and many Western European nations, but you should verify the specific country's rules before you travel.
  • Car rental companies may require an IDP even when the country does not, so check your rental agreement before booking.
  • An IDP must be obtained from your state's DMV or an authorized AAA office before you leave; you cannot get one at a border or airport.
  • An IDP is only valid when carried together with your original home license; the two documents work as a pair.

Countries that legally require an IDP

France, Germany, Italy, Spain, Austria, Greece, Portugal, and most countries in Central and South America legally require an IDP. In these places, driving with only your U.S. license can result in a fine, vehicle impound, or both, even if you are a tourist. The requirement exists regardless of how long you are staying or whether you are renting or driving your own car.

If you are planning to drive in any European Union country, assume an IDP is required unless you have confirmed otherwise with that country's transportation ministry or a car rental company operating there. The same applies to Mexico, Brazil, Argentina, Chile, and most other Latin American nations. Australia, New Zealand, and Canada generally accept a U.S. license alone, though carrying an IDP is still recommended as a backup.

Countries where an IDP is optional but recommended

The United Kingdom, Ireland, Japan, South Korea, Thailand, and several other countries do not legally require an IDP if you hold a valid U.S. driver's license. However, carrying one is still a good idea. An IDP can speed up a traffic stop, reduce confusion with police who may not read English fluently, and satisfy a rental company's insurance requirements even when the country does not mandate it.

In these optional-IDP countries, your U.S. license is the primary document. The IDP functions as a secondary verification. If you are only staying a few days and not renting a car, an IDP may not be worth the time and cost. If you are renting a vehicle or staying longer than a week, the small cost of an IDP is worth the protection.

What car rental companies require

Many international car rental companies require an IDP regardless of the country's legal requirement. Hertz, Avis, Budget, and Europcar often list an IDP as a condition of rental in their terms, particularly in Europe and Latin America. Some companies will rent to you without one but will charge a higher daily rate or require additional insurance. Others will refuse to rent altogether.

Before you book a rental car, check the rental agreement or call the company directly and ask whether an IDP is required for your destination. If it is listed as required and you do not have one, you will either need to obtain one before your trip or choose a different rental company. Do not assume that because the country does not legally require an IDP, the rental company will not.

How to obtain an IDP before you travel

An IDP is issued by your state's Department of Motor Vehicles or by an authorized AAA office. You cannot obtain one at a border, airport, or consulate. You must explore in person in most states, though a few states allow mail-in requests. The process takes one to two weeks if you explore in person and two to four weeks if you mail your process.

To obtain an IDP, bring your valid U.S. driver's license, a completed process form (available from your state DMV or AAA), and payment (typically $15 to $30). You will also need a passport-style photograph in some states. The IDP is issued on the spot or mailed to you within days. You can obtain a one-year or three-year IDP; the three-year version is more economical if you travel internationally more than once.

If you are leaving within two weeks and your state's DMV has long wait times, visit an AAA office instead. AAA can issue an IDP the same day in most locations. You do not need to be an AAA member, though membership may may have access to you to a discount.

How long an IDP is valid and when to renew

An IDP is valid for one or three years from the date of issue, depending on which version you request. It is only valid when carried together with your original U.S. driver's license. If your U.S. license expires before your IDP does, the IDP becomes invalid; you cannot use an expired license with a valid IDP.

If you are planning multiple international trips over several years, a three-year IDP is more economical than renewing a one-year permit each time. If you are taking a single trip, a one-year IDP is sufficient and costs less. You can renew an IDP by returning to your state DMV or AAA office with the same documents required for the initial process.

Common mistakes that create problems at borders and rental counters

The most common mistake is obtaining an IDP but leaving it at home. An IDP is only valid when you carry it with your original license. Carrying only the IDP or only your U.S. license defeats the purpose. Keep both documents together in your travel bag or wallet.

A second mistake is obtaining an IDP but not checking whether your U.S. license is still valid. If your license expires during your trip, your IDP becomes invalid even if it has time remaining. Renew your U.S. license before you travel if it expires within six months of your departure date.

A third mistake is assuming that because one country does not require an IDP, no country on your itinerary does. If you are driving through multiple countries, check the requirements for each one. An IDP covers all countries, so obtaining one before you leave is simpler than trying to get one mid-trip.

Frequently Asked Questions

Can I drive in Europe with just my U.S. license?

In some Western European countries like the UK and Ireland, yes. In France, Germany, Italy, Spain, and most other EU countries, no — an IDP is legally required. Before renting a car in Europe, confirm the requirement for each country you plan to visit. Most car rental companies in Europe require an IDP as a condition of rental regardless of local law.

What if I travel to a country that requires an IDP but I don't have one?

You cannot legally drive. If you are caught driving without an IDP in a country that requires one, you face a fine, vehicle impound, or both. If you arrive without an IDP and need to rent a car, contact the rental company when ready — some may refuse to rent, while others may charge a premium or require additional insurance. Do not attempt to drive without the required documents.

Is an IDP the same as an international license?

No. An IDP is a translation and verification document issued by your home country. An international license is a separate license issued by a foreign country after you have moved there or established residency. An IDP is temporary and valid for one to three years. An international license is permanent until it expires or you move again.

Do I need an IDP if I'm only driving for one day?

If the country requires one, yes. If the country does not require one but your rental company does, yes. If neither requires one, an IDP is optional but still recommended as backup. The cost is low and the protection is high, so most travelers obtain one regardless of trip length.

Can I get an IDP at the airport or border?

No. An IDP must be obtained from your state's DMV or an authorized AAA office before you leave your home country. Plan to obtain one at least one week before your departure date. If you are leaving within days, visit an AAA office, which can issue an IDP the same day in most locations.
