Most US drivers do not need an International Driving Permit to drive abroad, but some countries require one and car rental companies often demand it

An International Driving Permit (IDP) is a translation of your US driver's license into ten languages. It is not a separate license and does not replace your state license — you must carry both documents together. Whether you need one depends on where you are going, how long you are staying, and what you plan to do there. Some countries will let you drive on your US license alone. Others legally require an IDP. Rental car companies frequently refuse to rent to you without one, even in places where local law does not require it.

The practical answer: if you are renting a car, get an IDP before you leave. If you are driving your own vehicle or using a ride service, check the specific country's rules first. An IDP costs $20 and takes 15 minutes to obtain from the American Automobile Association (AAA) or American Automobile Touring Alliance (AATA), so the cost of being wrong is low.

Key Takeaways

  • An International Driving Permit is a certified translation of your US license and must be carried alongside your actual license, not instead of it.
  • Some countries legally require an IDP; others do not, but nearly all car rental companies will refuse to rent without one regardless of local law.
  • You can obtain an IDP from AAA or AATA in person for $20, and it is valid for one or three years depending on your age and which organization issues it.
  • An IDP does not change your driving rights or insurance coverage — your US license and your home auto insurance remain your primary documents.
  • If you are stopped by police in a country that requires an IDP and you do not have one, you may face fines, vehicle impoundment, or inability to legally drive.

Which countries require an International Driving Permit by law

Many popular destinations do not legally require an IDP if you hold a valid US driver's license. These include Canada, Mexico, the United Kingdom, Ireland, Australia, New Zealand, and most of Western Europe. However, some countries do require one: China, India, Japan, Russia, South Africa, and several others. The requirement also changes based on how long you stay — some countries allow you to drive on a US license for up to 30 days, then require an IDP if you stay longer.

The safest approach is to check the specific country's embassy website or contact their consulate before you travel. Requirements change, and what was true last year may not be true now. If you are renting a car, ask the rental company directly — they will tell you when ready whether they require an IDP, which is often stricter than what the country's law actually says.

Why rental car companies require an IDP even when the country does not

Rental companies use an IDP as proof that you have a valid, recognized license. It is a liability protection for them. If you are in an accident and you do not have an IDP in a country where the rental company's policy requires one, the company may deny your insurance claim or hold you liable for damages. This happens even if local law does not require the permit.

Some rental companies are stricter than others. Major international chains like Hertz, Avis, and Budget often require an IDP in any country outside North America and Western Europe. Smaller local rental companies may be more flexible. When you book a car, the rental agreement will state whether an IDP is required. If it does not mention it, call the rental location directly before you travel — do not assume it is optional.

How to get an International Driving Permit before you travel

You can obtain an IDP from two organizations in the United States: the American Automobile Association (AAA) and the American Automobile Touring Alliance (AATA). Both are authorized by the US State Department. You do not need to be a member of either organization to get an IDP from them.

To obtain an IDP, you will need your valid US driver's license, a passport or passport card, and a completed process form. AAA issues IDPs in person at their local offices — you can find the nearest one on their website. AATA issues them by mail; you send in your documents and they mail the permit back to you. AAA typically processes in-person requests when ready. AATA takes one to two weeks by mail.

The cost is $20 from either organization. An IDP issued to someone under 18 is valid for one year. An IDP issued to someone 18 or older is valid for three years. You will need to renew it if it expires while you are abroad, though most travelers do not stay long enough for this to matter.

What an International Driving Permit does and does not do

An IDP translates your US license into multiple languages so that police and rental companies can verify that you hold a valid license. It does not grant you any additional driving rights. You still must obey the traffic laws of the country you are in. You still must be of legal driving age in that country. You still must follow any restrictions on your US license — if your license is suspended or restricted, an IDP does not override that.

An IDP also does not change your insurance coverage. Your US auto insurance policy does not automatically cover you abroad. If you are driving your own vehicle, you will need to contact your insurance company before you travel to ask whether your policy extends to the country you are visiting and what coverage applies. If you are renting a car, the rental company's insurance will cover you, but only if you have met all their requirements — including having an IDP if they require one.

What happens if you drive without an International Driving Permit when one is required

If you are stopped by police in a country that requires an IDP and you do not have one, the consequences vary. In some countries, you will receive a fine on the spot. In others, police may impound your vehicle until you produce the permit or pay a penalty. In a few countries, driving without a required IDP can result in criminal charges, though this is rare for tourists.

More commonly, if you are in an accident and you do not have an IDP in a country where it is required, your rental car insurance may not cover the damage. You could be held personally liable for repair costs, medical bills, or third-party claims. This can cost thousands of dollars. Even if the country's law does not strictly require an IDP, if your rental agreement says you must have one and you do not, the rental company can deny your claim.

Alternatives if you cannot get an International Driving Permit in time

If you are traveling soon and cannot obtain an IDP before you leave, your options are limited. AAA can issue one in person the same day at most locations, so if you live near an AAA office, you can get one before your flight. If you do not have time for that, contact your rental car company when ready and explain the situation. Some companies will make exceptions or offer alternative solutions, though this is not may provide.

If you are renting a car and cannot get an IDP, some companies will allow you to rent if you sign a waiver acknowledging that you do not have one and accepting liability for any issues that arise. This is not ideal — you are assuming financial risk — but it is sometimes possible. Do not show up at the rental counter without an IDP and hope for the best. Call ahead and ask what options exist.

If you are driving your own vehicle and the country requires an IDP, you have no alternative. You cannot legally drive without one. You would need to postpone the trip or arrange other transportation.

Frequently Asked Questions

Can I use my passport as proof of identity instead of an International Driving Permit?

No. A passport proves your citizenship and identity, but it does not prove you hold a valid driver's license. Police and rental companies need to see that you are licensed to drive. Your US driver's license and IDP together serve that purpose. You will need both your passport and your IDP when you travel.

Is an International Driving Permit the same as an international license?

No. An IDP is a translation document. An international license is a separate license issued by another country. If you move to another country or become a resident there, you will eventually need to obtain that country's driver's license. An IDP is only for temporary visitors.

Do I need an International Driving Permit to drive in Canada or Mexico?

No. Canada and Mexico recognize US driver's licenses. You do not need an IDP to drive in either country. However, if you are renting a car from a major rental company, check your rental agreement — some companies require an IDP anyway, even though local law does not.

What if my US driver's license is suspended or expired?

You cannot get an IDP if your US license is suspended, revoked, or expired. An IDP is a translation of your current, valid license. If your license is not valid in the US, it is not valid abroad either. You must renew or restore your US license before you can obtain an IDP.

How long is an International Driving Permit valid?

An IDP is valid for one year if you are under 18 years old, and three years if you are 18 or older. It expires on the date printed on the permit. If you are planning a long trip or multiple trips abroad, check the expiration date before you leave to make sure it will still be valid when you travel.
