What you need to drive legally in Mexico

To drive in Mexico, you need either your valid U.S. driver's license plus an International Driving Permit (IDP), or your U.S. license alone if you're staying in the border region for a short trip. Mexico recognizes U.S. licenses, but an IDP is a translation document that makes your license valid in more situations — particularly if you're renting a car, crossing deep into the country, or stopped by police far from the border.

An IDP is not a separate license. It's a booklet that translates your driver's license information into Spanish and ten other languages, and it's only valid when carried together with your actual U.S. driver's license. Mexican authorities accept it as proof that you're a licensed driver in your home country.

The rules differ slightly depending on how far into Mexico you're traveling and how long you're staying. Border towns have more relaxed enforcement, but the farther south you go, the more important an IDP becomes.

Key Takeaways

  • An International Driving Permit is a translation of your U.S. driver's license and must be carried with your actual license at all times in Mexico.
  • You can obtain an IDP from the American Automobile Association (AAA) or the American Automobile Touring Alliance (AATA) before you leave the United States.
  • An IDP costs between $15 and $20 and takes about one to two weeks to arrive by mail, or you can get one the same day at an AAA office if you visit in person.
  • Mexico does not issue its own international permits; you must bring one from the U.S., and it's valid for one year from the date of issue.
  • Car rental companies in Mexico often require an IDP even if Mexican law does not, so check your rental agreement before you book.

Where to get an International Driving Permit before you travel

The American Automobile Association (AAA) is the easiest and most common source for an IDP. You can visit any AAA office in person with your valid U.S. driver's license and a passport or passport card, pay the fee, and receive your IDP on the same day. If you don't have an AAA membership, you can still purchase an IDP; membership is not required.

The American Automobile Touring Alliance (AATA) is the second option. You can order an IDP by mail through their website or by phone. You'll need to send a photocopy of your driver's license and a completed process form. Processing takes one to two weeks, and the IDP arrives by mail.

Do not wait until you arrive in Mexico to get an IDP. Mexico does not issue international permits, and you cannot obtain one once you're in the country. Plan ahead and get yours before you cross the border.

What documents you need to explore

To get an IDP from AAA in person, bring your valid U.S. driver's license and either a passport, passport card, or state ID. You do not need a membership card; AAA staff can look up your membership by name if you're already a member, or you can purchase an IDP without membership.

If you're ordering by mail through AATA, you'll need to send a photocopy of your driver's license (front and back), a completed process form (available on their website), and payment. Some locations also accept online orders with a digital copy of your license.

Your IDP will be issued in your name as it appears on your driver's license. Make sure the spelling matches exactly, because Mexican officials will compare the two documents.

How long an International Driving Permit lasts and when to renew

An IDP is valid for one year from the date it is issued. If your IDP expires while you're in Mexico, it is no longer valid, and you should not drive. You cannot renew an IDP in Mexico; you must return to the United States or obtain a new one before you travel again.

If you plan to drive in Mexico multiple times in a year, check the expiration date on your IDP before each trip. If it will expire during your stay, order a new one before you leave the U.S.

Your U.S. driver's license itself does not expire just because your IDP does. The IDP is a separate document with its own expiration date.

Car rental companies and IDP requirements

Most car rental companies in Mexico require an International Driving Permit, even though Mexican law technically allows you to drive on a U.S. license alone. Some rental agencies will refuse to rent to you without one, while others may charge an extra fee or require you to purchase additional insurance if you don't have an IDP.

Before you book a rental car, check the company's website or call to confirm their IDP policy. Major chains like Hertz, Avis, and Budget have different rules depending on the location and the type of vehicle. It's safer to have an IDP than to arrive at the rental counter and discover you can't rent the car you reserved.

If you're renting a car, also bring your U.S. driver's license, your passport, and a credit card in your name. Mexican rental companies are strict about matching names and documents.

Driving in border towns versus driving deeper into Mexico

If you're staying within a few miles of the U.S. border — in towns like Tijuana, Ciudad Juárez, or Nuevo Laredo — you can often drive on your U.S. license alone without an IDP. Border towns see many American visitors, and local police are accustomed to U.S. licenses. However, this is not may provide, and an IDP still protects you if you're stopped.

If you're traveling more than 50 miles inland or staying for more than a few days, an IDP becomes much more important. Police in smaller towns and rural areas are less familiar with U.S. licenses, and they may not speak English. An IDP removes the language barrier and proves you're a licensed driver in your home country.

Even in border towns, car rental companies almost always require an IDP. Don't assume that being close to the border means you can skip it.

What to do if you're stopped by police while driving

If a Mexican police officer stops you, stay calm and have both your U.S. driver's license and your IDP ready. Hand both documents to the officer at the same time. The IDP translates your license information, so the officer can verify your identity and driving status without needing to speak English.

Do not drive without your IDP if you have one. Carrying it costs nothing and removes any question about whether you're a licensed driver. If you're stopped without it, you may face a fine or be unable to continue driving.

Keep your IDP in the same place as your driver's license — in your wallet or a document holder in your car. Do not leave it at your hotel or in checked luggage.

Frequently Asked Questions

Can I drive in Mexico on just my U.S. driver's license without an IDP?

Technically yes, especially in border towns, but it's risky. Mexican law recognizes U.S. licenses, but car rental companies almost always require an IDP, and police in smaller towns may not accept a U.S. license alone. An IDP costs $15 to $20 and takes the guesswork out of the situation.

How much does an International Driving Permit cost?

An IDP costs between $15 and $20, depending on whether you get it from AAA or AATA. AAA charges around $15 to $20 for members and non-members alike. AATA charges a similar amount. There are no hidden fees, and the price does not change based on how long you're staying in Mexico.

What if my IDP expires while I'm in Mexico?

You cannot drive legally once your IDP expires. You also cannot renew it in Mexico. If your IDP will expire during your trip, order a new one before you leave the U.S., or plan your travel dates so you return before it expires.

Do I need an IDP if I'm only driving in Tijuana for a day?

You may not be stopped, but if you are, an IDP protects you. If you're renting a car, the rental company will likely require one regardless of how short your trip is. It's better to have it than to discover you can't rent the car or face a fine.

Can I get an International Driving Permit in Mexico?

No. Mexico does not issue international driving permits. You must obtain one in the United States before you travel. Plan ahead and get yours from AAA or AATA at least one week before your trip.
