International driving permits are valid for one or three years, depending on which type you get

An International Driving Permit (IDP) is a document that translates your home country's driver's license into ten languages. It does not replace your license — you must carry both together. The validity period depends on which of the two IDP formats you obtain. A one-year permit costs less and works for short trips. A three-year permit costs more but covers longer stays or frequent travel. Neither type extends beyond your home country's license expiration date, so if your license expires in two years, a three-year IDP will stop working when your license does.

The IDP is issued by your home country's motor vehicle authority, not by the country you plan to visit. In the United States, you request it through your state's Department of Motor Vehicles. You cannot renew or replace an IDP while outside your home country, so timing matters when you order one.

Key Takeaways

  • The one-year IDP is valid for exactly one year from the date of issue; the three-year IDP is valid for exactly three years.
  • Your IDP becomes invalid the moment your home country's driver's license expires, even if the IDP itself has time remaining.
  • You must carry both your IDP and your original driver's license together at all times when driving abroad.
  • The one-year permit costs $15 to $30 and suits short trips; the three-year permit costs $20 to $40 and is more economical for frequent travelers.

The one-year permit: cost, timing, and when to choose it

A one-year IDP costs between $15 and $30 in the United States, depending on your state's motor vehicle department. It is issued on the date you request it and expires exactly one year later. This option makes sense if you are taking a single trip abroad, a short-term work assignment, or a vacation lasting weeks or a few months.

The one-year permit is also useful if your home license is expiring soon. If your license expires in eight months and you need an IDP for a trip in six months, buying a one-year permit means you will not have to renew it before your trip ends. A three-year permit would expire when your license does, leaving you with unused time and wasted money. Order the one-year version if you are uncertain how long you will need to drive abroad.

The three-year permit: cost, timing, and when to choose it

A three-year IDP costs between $20 and $40 in the United States, again depending on your state. It is issued on the date you request it and remains valid for three full years. This option suits people who travel internationally multiple times per year, live abroad temporarily, or want a backup document on hand for unexpected trips.

The three-year permit is more economical if you plan to drive in other countries more than once during that window. The per-year cost is lower than buying a one-year permit three times. However, you lose the unused portion if your home license expires before the three-year mark. Check your license expiration date before ordering a three-year permit, and do the math: if your license expires in two years and four months, a three-year IDP will only work for two years and four months.

When your IDP stops working, even if it says it is still valid

An IDP is only as valid as the license it translates. If your home country's driver's license expires on March 15, 2026, your IDP — whether one-year or three-year — stops working on March 15, 2026, regardless of its own expiration date. Rental car companies, police, and border officials will reject an IDP paired with an expired license.

This means you need to renew your home license before your IDP expires if you plan to keep driving abroad. Some people renew their license early specifically to extend the life of their IDP. Check your license expiration date on the card itself; it is usually printed in small text on the back or front. If you are planning a long trip or move abroad, renew your home license before you leave.

How to obtain an IDP in the United States

You request an IDP through your state's Department of Motor Vehicles (DMV). Most states allow you to explore in person at a DMV office, by mail, or online through the state's website. You will need your valid driver's license, proof of residency, and a completed process form. Processing usually takes one to two weeks if you explore in person; mail applications take longer, sometimes three to four weeks depending on the state.

Fees and exact procedures vary by state. Some states issue the IDP on the spot during an in-person visit; others mail it to you. A few states offer expedited processing for an additional fee. Visit your state's DMV website to find the current process form, fee, and processing time. Do not use third-party websites that claim to issue IDPs — they are not authorized by your state and will waste your money. The official DMV is your only legitimate source.

What happens if your IDP expires while you are abroad

If you are driving in another country and your IDP expires, you can no longer legally drive. You cannot renew an IDP while outside your home country. If your trip is longer than expected or your IDP is about to expire, you have two options: stop driving and use other transportation, or return home to renew it.

Some countries allow you to drive on an expired IDP for a grace period of a few days, but this varies widely and is not may provide. Do not rely on it. Plan your trip so that your IDP does not expire while you are still driving. If you are moving abroad for work or study, renew your home license and IDP before you leave, or arrange to have them renewed by mail while you are away. Contact your state DMV to ask whether they accept mail-in renewals from abroad.

IDP validity across different countries

An IDP issued by the United States is recognized in most countries that are signatories to the 1926 or 1968 United Nations Convention on Road Signs and Signals. This includes most of Europe, Asia, Australia, and Latin America. However, some countries do not recognize the IDP or have additional requirements. China, Russia, and a few others require you to obtain a separate domestic driving permit or an International Driving License issued by that country's authorities.

Before you travel, check the driving requirements for your specific destination. Your rental car company or your destination country's embassy website will tell you whether an IDP is sufficient or whether you need additional documents. An IDP is never a substitute for local knowledge of traffic laws, which vary significantly by country. Some countries have different speed limits, different rules about which side of the road to drive on, or different requirements for carrying documents in your vehicle.

Frequently Asked Questions

Can I renew my IDP before it expires?

Yes. You can request a new IDP at any time, even if your current one has not expired. This is useful if you are about to renew your home license and want a fresh three-year IDP that will last longer. You will pay the full fee for the new permit; there is no discount for early renewal.

What if I lose my IDP while traveling?

You cannot replace an IDP while abroad. Contact your home country's embassy or consulate to ask whether they can issue a temporary replacement or letter confirming your license status. In most cases, you will need to stop driving until you return home and can request a new IDP from your DMV.

Do I need an IDP if I am only renting a car for a day?

It depends on the country and rental company. Some rental agencies in Europe and Asia require an IDP even for short rentals. Others accept your home license alone. Check with the rental company before you book. It is safer to have an IDP than to arrive and discover you cannot rent the car.

Is an IDP the same as an International Driving License?

No. An IDP is issued by your home country's motor vehicle authority and is recognized in most countries. An International Driving License is a separate document issued by some countries' authorities and is not widely recognized. The IDP is what you need for most international travel.

Can I use an expired IDP if my home license is still valid?

No. An expired IDP is not valid, even if your home license has not expired. You must carry a current IDP and a current home license together. If your IDP expires, you need to renew it before driving abroad again.
