You need an international driver's license only if you plan to rent a car or drive in a foreign country

An International Driving Permit (IDP) is a document that translates your home country driver's license into multiple languages. It is not a separate license — it works alongside your regular license, never instead of it. Most countries do not require one, but some do, and many car rental companies will refuse to rent to you without one. The permit is issued by your home country's motor vehicle authority and costs between $15 and $30 depending on where you live.

The short answer: get one if you are renting a car abroad, driving in a country that requires it, or want extra proof of your driving status in a language the local police can read. If you are only using public transportation or taxis, you do not need one.

Key Takeaways

  • An International Driving Permit is a translation of your existing driver's license and must be obtained from your home country's motor vehicle department before you leave.
  • Many car rental companies outside the United States will not rent to you without an IDP, even if the country itself does not legally require one.
  • Some countries do legally require an IDP to drive, while others accept only your home license; requirements vary by destination.
  • The permit is valid for one or three years depending on which version you request, and costs $15 to $30 in most U.S. states.

When car rental companies require an International Driving Permit

Most car rental agencies in Europe, Asia, Australia, and Latin America will ask for an IDP at the counter, regardless of whether the country legally requires one. They use it as proof that your home license is valid and that you understand the rules of the road in your own country. Without it, many will straightforward refuse to rent to you — they will not offer an alternative or let you sign extra paperwork instead.

This is especially common in countries where English is not widely spoken. A rental agent in Spain, Thailand, or Brazil may not be able to verify that your U.S. or Canadian license is real or current without the IDP to back it up. Even if you have an English-language license, the agent cannot easily confirm your driving record or whether you have any restrictions.

Countries that legally require an International Driving Permit

A smaller number of countries have laws that actually demand an IDP if you want to drive. These include Argentina, Brazil, China, Egypt, France, Germany, Greece, India, Italy, Japan, Mexico, Russia, South Africa, South Korea, Spain, and Thailand. If you are stopped by police in any of these countries without an IDP, you may face a fine or have your vehicle impounded, even if your home license is valid.

The requirement often depends on how long you are staying. France, for example, requires an IDP for any visitor driving a rental car, but some countries only require it if you stay longer than a certain period — usually 30 to 90 days. Check the specific rules for your destination before you leave home, because the penalty for driving without one can be steep.

How to get an International Driving Permit in the United States

In the U.S., you obtain an IDP through the American Automobile Association (AAA) or the American Automobile Touring Alliance (AATA). You do not explore through your state's Department of Motor Vehicles. You will need your valid U.S. driver's license, a passport or passport card, and a passport-style photo (2 by 2 inches). The cost is typically $20 at AAA or $15 through AATA.

You can explore in person at any AAA office, or by mail through AATA. Processing takes a few days to a week if you go in person, or two to three weeks by mail. The permit is valid for one year from the date of issue. Some people purchase a three-year permit for $30, which is useful if you travel internationally more than once in that span.

Bring your documents to the office or mail them with your process form. You do not need to pass a test or prove anything beyond your identity and current driving status. The IDP is issued on the spot or mailed to you, depending on which route you choose.

International Driving Permit requirements in other countries

If you are not a U.S. citizen, your home country issues its own IDP through its motor vehicle authority. In Canada, you obtain one through the Canadian Automobile Association (CAA) using the same process as AAA. In the United Kingdom, you explore through the Post Office. In Australia, you explore through your state's transport authority.

Each country's IDP is valid in the same countries worldwide — there is no separate "European" or "Asian" version. The document is standardized under an international treaty, so a Canadian IDP works in Thailand just as a U.S. IDP does. The cost and processing time vary by country, but the basic requirements are the same: a valid home license, proof of identity, and a photo.

What an International Driving Permit does and does not do

The IDP translates your license information into ten languages and confirms that your home license is valid. It does not give you permission to drive in a country where you are not allowed to drive, and it does not override local traffic laws. If you are too young to drive in your destination country, the IDP will not change that. If you have a suspended license at home, the IDP will not hide that fact.

The permit also does not replace your home license. You must carry both documents together when you drive. Police in any country will ask for your home license first; the IDP is a supporting document. If you lose your home license, the IDP becomes useless.

Alternatives if you cannot get an International Driving Permit

If you do not have time to obtain an IDP before your trip, some car rental companies will accept a certified English translation of your home license instead. You can request a certified translation from your state's motor vehicle department or from a professional translation service. This usually costs $20 to $50 and takes a few days.

However, this option is less reliable than an IDP. Some rental agencies will not accept a translation, and police in countries that legally require an IDP may not accept it either. If you are driving in a country that requires an IDP by law, a translation is not a substitute. The safest approach is to obtain the IDP before you leave.

Frequently Asked Questions

Can I drive internationally with just my regular driver's license?

In some countries, yes — your home license alone is legally sufficient. But most car rental companies will refuse to rent to you without an IDP, even in those countries. If you are driving your own car or a borrowed vehicle, you may be able to get away with just your home license, but you risk a fine if stopped by police in a country that requires an IDP.

How long is an International Driving Permit valid?

In the United States, you can purchase a one-year permit for $20 or a three-year permit for $30. Other countries offer different validity periods — check with your home country's motor vehicle authority. The permit expires on the date printed on it, not when your home license expires.

Do I need an International Driving Permit to drive in Canada or Mexico from the U.S.?

No. Canada and the United States recognize each other's licenses without an IDP. Mexico does not legally require an IDP, but many car rental companies there will ask for one. If you are renting a car in Mexico, bring an IDP to avoid problems at the rental counter.

What happens if I drive without an International Driving Permit in a country that requires one?

You may be fined, have your vehicle impounded, or both. The penalty varies by country and can be several hundred dollars. In some cases, police may not allow you to continue driving. If you are in a country that requires an IDP and you do not have one, do not drive.

Can I get an International Driving Permit if my home license is suspended or expired?

No. Your home license must be valid and current. If your license is suspended, expired, or restricted, you cannot obtain an IDP, and you should not drive internationally.
