An IDP is an official translation of your driver license into multiple languages, issued by your home country — not a separate license itself

An International Driving Permit (IDP) is a document that translates your valid driver license into ten languages recognized by the United Nations. It is not a license that lets you drive in the United States. If you hold a valid driver license from another country and plan to drive in the U.S., your original license is what allows you to operate a vehicle — the IDP is a companion document that helps you if you are stopped by police or need to rent a car.

The IDP is issued by your home country's automobile association or equivalent government body, not by U.S. state DMVs. You must explore for it before you leave your home country. Once you arrive in the U.S. and decide to transfer to a state driver license, the IDP becomes less relevant, though it may still be useful if you travel back and forth internationally.

Many people confuse the IDP with a U.S. driver license or think it allows them to drive legally in America without getting a state license. It does not. U.S. states do not recognize an IDP as a substitute for a state-issued driver license.

Key Takeaways

  • An IDP is a translation document issued by your home country, not a U.S. license, and does not replace the need for a state driver license.
  • You must obtain an IDP from your home country's automobile association or equivalent body before leaving your country.
  • An IDP is valid for one year from the date of issue and is most useful for international travel or short-term visits to the U.S.
  • If you plan to live in the U.S. or drive regularly, you will need to transfer to a state driver license within the timeframe your state allows for out-of-state license holders.
  • Some car rental companies accept an IDP plus your original license, but many U.S. rental agencies prefer or require a U.S. state driver license.

How an IDP differs from a state driver license

A state driver license is a legal document that authorizes you to operate a motor vehicle in that state. It is issued by the state DMV after you pass a written test, vision test, and driving test (or are exempted from testing based on your out-of-state license). A state license is what law enforcement recognizes as proof that you are permitted to drive.

An IDP is purely a translation tool. It does not grant you any driving authority in the U.S. If you are pulled over by police while driving in the U.S., you must present your valid driver license from your home country plus the IDP. The IDP helps the officer understand what your home country license says, but the IDP itself is not proof of driving permission. If you do not have a valid home country license or a state license, the IDP alone will not protect you from a citation for driving without a license.

Think of the IDP as similar to a passport translation: it explains what your original document says, but it does not replace the original document itself.

Who issues an IDP and how to obtain one

Your home country's national automobile association or equivalent government agency issues the IDP. In most countries, this is a specific organization designated by your government to handle international driving permits. You cannot obtain an IDP from a U.S. DMV, and you cannot obtain one after you arrive in the United States.

You must explore for an IDP in your home country before you travel. The process varies by country, but typically involves submitting your valid driver license, a passport or national ID, a passport-sized photograph, and a completed process form. Some countries allow you to explore online or by mail; others require you to visit an office in person. Processing times range from a few days to several weeks, depending on the country and the method you choose.

Common organizations that issue IDPs include the American Automobile Association (AAA) for U.S. citizens traveling abroad, the Automobile Association in the United Kingdom, the Royal Automobile Club in Australia, and equivalent bodies in other nations. If you are unsure which organization issues IDPs in your country, contact your country's embassy or consulate in the U.S., or search your country's name plus "international driving permit" to find the official issuing body.

How long an IDP is valid and when it expires

An IDP is valid for one year from the date it is issued. After one year, it expires and is no longer recognized as a valid translation document. If you need to drive internationally again after your IDP expires, you must obtain a new one from your home country's issuing body.

The validity of your IDP is separate from the validity of your home country driver license. Your home country license may be valid for five, ten, or more years, but your IDP will still expire after one year. If your home country license expires before your IDP does, the IDP becomes useless because it is a translation of an expired license.

If you transfer to a state driver license in the U.S., your IDP does not need to be renewed. Once you hold a valid state license, you no longer need the IDP for driving within the U.S., though you may still want to keep it if you travel internationally.

Using an IDP to rent a car in the U.S.

Car rental companies in the U.S. have different policies about accepting an IDP. Some rental agencies will accept your home country driver license plus an IDP as proof of driving authorization. Others require a U.S. state driver license or will charge a higher daily rate if you present only a foreign license and IDP. A few rental companies will not rent to you at all without a U.S. license.

Before you arrive in the U.S., contact the rental company you plan to use and ask whether they accept an IDP plus a home country license, or whether they require a state license. If the company requires a state license, you will need to transfer your out-of-state license to a state driver license before you can rent a car from them. The timeline for this varies by state — some states allow you to drive on a foreign license for 30 days, others for 60 days or longer — so check your specific state's rules.

Even if a rental company accepts an IDP, they may still require a credit card in your name and may charge a higher deposit or daily fee for non-U.S. license holders. Read the rental agreement carefully before you sign.

When you need to transfer from an IDP to a state driver license

If you plan to stay in the U.S. for more than a few weeks or months, or if you plan to live in the U.S., you will need to transfer to a state driver license. Each state sets its own timeline for how long you can drive on a foreign license before you must transfer. Some states allow 30 days, others allow 60 days, and a few allow up to one year. Check your specific state's DMV website to find the important date.

To transfer to a state driver license, you will visit your state DMV with your home country driver license, your IDP (optional but helpful for verification), your passport or national ID, proof of residency, and proof of your Social Security number or tax ID. You will pay a transfer fee, which varies by state. Some states will waive the written test and driving test if your home country license is valid and you meet other requirements; others will require you to pass both tests.

Once you hold a valid state driver license, you no longer need the IDP for driving in the U.S. If you travel back to your home country or to other countries, you may want to keep the IDP for reference, but it is no longer required for U.S. driving.

Common mistakes when using an IDP in the U.S.

The most common mistake is assuming an IDP is a valid U.S. driver license. It is not. Driving in the U.S. without a valid state license or a valid home country license is illegal, even if you have an IDP. If you are pulled over and cannot present a valid license, you can be cited for driving without a license, regardless of whether you have an IDP.

Another mistake is not obtaining an IDP before you leave your home country. Once you arrive in the U.S., you cannot obtain an IDP from a U.S. DMV or any U.S. agency. If you did not get one before you left, you will have to rely on your home country license alone, which may not be accepted by some car rental companies or may be harder for police to verify.

A third mistake is not checking your state's important date for transferring to a state license. If you overstay the allowed period on a foreign license, you may be cited for driving without a valid license, even if your home country license is still valid. Check your state DMV website for the exact important date and plan to transfer before that date.

Frequently Asked Questions

Can I drive in the U.S. with just an IDP and no other license?

No. An IDP is only a translation of your home country driver license. You must have a valid home country driver license to carry with the IDP. If you do not have a valid home country license, the IDP alone does not authorize you to drive in the U.S. You will need a state driver license.

How much does an IDP cost?

The cost varies by country. In the United States, the AAA charges between $15 and $20 for an IDP. Other countries charge different amounts. Contact your home country's issuing body for the exact fee.

Do I need an IDP if I already have a state driver license?

No. Once you hold a valid state driver license, you do not need an IDP for driving in the U.S. You may want to keep an IDP if you travel internationally, but it is not required for U.S. driving.

What if my home country driver license is expired?

You cannot use an expired home country license to drive in the U.S., and an IDP based on an expired license is also invalid. You must transfer to a state driver license before your home country license expires, or renew your home country license before it expires.

Can I renew my IDP in the U.S.?

No. IDPs are issued only by your home country's automobile association or equivalent body. You cannot renew an IDP in the U.S. If your IDP expires and you need a new one, you will have to contact your home country's issuing body or wait until you return to your home country.
