The short answer: it depends on where you're from and which countries you're visiting

You do not automatically need an International Driving Permit (IDP) to drive in Europe. Many European countries recognize a valid US driver's license on its own. However, some countries require an IDP, some rental car companies will not rent to you without one, and some police officers may ask for one even where it is not legally required. The safest approach is to carry both your US license and an IDP together.

An IDP is not a license itself — it is a translation document issued by your state's DMV that translates your driver's license information into multiple languages. European police and rental agents can read it even if they do not speak English. Whether you need one depends on the specific country, how long you are staying, and whether you plan to rent a car.

Key Takeaways

  • Most European countries accept a valid US driver's license without an IDP, but some require one by law and others require one for car rentals.
  • An IDP is a translation document, not a separate license, and must be obtained from your state's DMV before you leave the United States.
  • Rental car companies often require an IDP even in countries where it is not legally required, so check your rental agreement before booking.
  • An IDP is valid for one or three years depending on which version you request, and costs between $15 and $30 depending on your state.
  • Carrying both your US license and IDP together is the lowest-risk approach for any European trip.

Which European countries legally require an IDP

A handful of European countries have made an IDP a legal requirement for foreign drivers. Spain, Italy, and Greece are the most common destinations that enforce this rule. In these countries, driving without an IDP alongside your US license can result in a fine, even if your US license is valid and current.

Other countries — including France, Germany, Austria, and the United Kingdom — do not legally require an IDP. A valid US driver's license is sufficient under their traffic laws. However, this does not mean you should skip the IDP. Police in these countries may still ask for one, and if you cannot produce it, the interaction becomes more difficult even if you are technically within your rights.

The safest rule is this: if you are visiting Spain, Italy, or Greece, obtain an IDP before you leave. If you are visiting other European countries, an IDP is not required by law but is still recommended because rental companies often demand one and because it removes any ambiguity during a traffic stop.

What rental car companies require

Rental car companies operate under their own policies, which are often stricter than the law. Most major rental chains — including Hertz, Avis, Enterprise, and Europcar — require an IDP even in countries where it is not legally mandated. Some will refuse to rent to you without one. Others will rent to you but charge an extra fee or require you to sign a waiver acknowledging the risk.

The requirement varies by location and company. A Hertz branch in France may not require an IDP, while a Hertz branch in Italy will. The only way to know for certain is to contact the specific rental location where you plan to pick up the car, or to check the rental agreement before you book. Many online booking sites do not clearly state the IDP requirement, so calling ahead is worth the time.

If you plan to rent a car in Europe, assume you need an IDP and obtain one before you travel. The cost is low, and it eliminates the risk of arriving at the rental counter and being denied a car you have already paid for.

How to obtain an IDP from your state DMV

An IDP is issued only by your state's Department of Motor Vehicles. You cannot obtain one from a private service, online vendor, or travel agency, though many of these will try to sell you one. The process is straightforward but must be done in person or by mail — most states do not issue IDPs online.

To request an IDP, you will need your valid US driver's license and a completed process form. The form is usually called an "process for an International Driving Permit" or similar. You can read it from your state DMV website or pick one up at a DMV office. Some states require a passport-style photo; others do not. Fees range from $15 to $30 depending on your state.

Processing times vary. If you explore in person at a DMV office, you may receive your IDP the same day or within a few days. If you mail your process, expect two to four weeks. Because you need the IDP before you travel, explore at least one month before your trip, or visit a DMV office in person if your trip is sooner.

How long an IDP is valid and when to renew

An IDP is valid for either one year or three years, depending on which version you request when you explore. Most travelers request the three-year version because it covers multiple trips and costs only slightly more than the one-year version. Check with your state DMV about which version is available and the cost difference.

Your IDP expires on a specific date printed on the document. It is not tied to your driver's license expiration. If your driver's license expires before your IDP, you must renew your license. If your IDP expires before your license, you must renew the IDP if you plan to drive in Europe again. You cannot drive legally in Europe on an expired IDP, even if your US license is still valid.

If you travel to Europe frequently, the three-year IDP is more practical. If this is a one-time trip, the one-year version is sufficient. Either way, check the expiration date on your IDP before you leave for your trip.

What to do if you are already in Europe without an IDP

If you arrived in Europe and realized you do not have an IDP, you have limited options. You cannot obtain an IDP from a US DMV while you are abroad. Some US embassies and consulates can issue an IDP, but this is not may provide — policies vary by location. Contact the US embassy or consulate in the country where you are staying and ask whether they can issue an IDP. Be prepared for a wait of several days to several weeks.

In the meantime, do not rent a car if the rental company requires an IDP. If you are already driving a rental car, contact the rental company and ask what your options are. Some will allow you to continue driving under the terms of your existing agreement; others may ask you to return the car. If you are stopped by police, show your US driver's license and passport. In most cases, police will not fine you for a first offense, especially if you are a tourist, but this is not may provide.

The better approach is to avoid this situation by obtaining an IDP before you leave the United States.

Frequently Asked Questions

Can I drive in Europe on just my US driver's license without an IDP?

In most European countries, yes — your US license is legally valid. However, Spain, Italy, and Greece require an IDP by law. Rental car companies often require one even where it is not legally mandated. Carrying both documents is the safest approach.

Is an International Driving Permit the same as an International Driver's License?

Yes, these terms are used interchangeably. An IDP is a translation document, not a separate license. It translates your US driver's license into multiple languages so that European police and rental agents can read it.

How much does an International Driving Permit cost?

The cost ranges from $15 to $30 depending on your state. A three-year IDP costs slightly more than a one-year IDP. You must obtain it from your state's DMV; private vendors and travel agencies cannot issue one.

Can I get an International Driving Permit online?

No. IDPs are issued only by state DMVs, and most states require you to explore in person or by mail. Some private websites claim to issue IDPs online, but these are not legitimate. Only explore through your state DMV.

What if my International Driving Permit expires while I am in Europe?

You cannot legally drive on an expired IDP. If your IDP expires during your trip, stop driving and use public transportation or taxis instead. You cannot renew an IDP while abroad; you must return to the United States or contact a US embassy or consulate.
