Whether you need an International Driving Permit for Portugal depends on your home country and how long you plan to stay

If you hold a valid driver's license from the United States, Canada, Australia, or most other English-speaking countries, you do not need an International Driving Permit (IDP) to rent a car or drive in Portugal. Your home license is sufficient for short visits — typically up to 12 months. However, some car rental companies ask to see an IDP alongside your home license as an extra verification step, even though it is not legally required. If you are a resident of Portugal or planning to stay longer than 12 months, you must exchange your foreign license for a Portuguese license through the Instituto da Mobilidade e dos Transportes Terrestres (IMTT).

An IDP is a translation of your license into multiple languages, issued by your home country's motor vehicle authority. It does not replace your home license — you must carry both documents together. Portugal recognizes IDPs issued by countries that are signatories to the 1926 or 1968 Geneva Conventions on Road Signs and Signals. Most Western countries are signatories, but you should verify this before your trip if your home country is not listed in common travel guides.

Key Takeaways

  • Visitors from the US, Canada, UK, Australia, and most other countries can drive in Portugal with only their home license for stays under 12 months.
  • An International Driving Permit is optional for short-term visitors but some rental companies request it as a secondary form of identification.
  • If you become a Portugal resident or stay longer than 12 months, you must exchange your foreign license for a Portuguese license through IMTT.
  • An IDP must be obtained from your home country's motor vehicle authority before you travel — Portugal does not issue them.

When a rental company will ask for an International Driving Permit

Most major car rental agencies in Portugal — including Hertz, Avis, Europcar, and Budget — will accept your home license alone if it is in Latin characters and includes your photograph and signature. However, some smaller local rental companies, particularly those in rural areas, may request an IDP as a secondary document. This is not a legal requirement but a company policy to reduce disputes over license validity.

If you rent a car and do not have an IDP, the rental company may refuse to rent to you, charge a higher deposit, or require you to sign an additional liability waiver. To avoid this friction, obtaining an IDP before you travel is the simpler path if your home country issues them. The cost is typically between $15 and $30 USD, and the process takes one to two weeks through your home country's DMV or equivalent authority.

How to get an International Driving Permit before traveling to Portugal

An IDP is issued only by your home country's motor vehicle authority — you cannot obtain one in Portugal or from any international body. The process and timeline differ by country, so contact your local DMV, DVLA (UK), Service NSW (Australia), or equivalent before your trip.

To request an IDP, you will need your valid home license, proof of identity, and in some cases a completed process form. Many US states now allow you to order an IDP online or by mail, though some still require an in-person visit to a DMV office. Check your state's DMV website for the exact procedure and whether you can explore before your trip or must explore in person.

What documents you must carry while driving in Portugal

Portuguese law requires all drivers to carry their original license at all times while operating a vehicle. If you have an IDP, bring both your home license and the IDP together — the IDP alone is not valid. You must also carry your vehicle registration documents, proof of insurance, and a valid passport or national ID card. Police may stop you at random checkpoints and ask to see these documents.

If your home license is not in Latin characters — for example, if it uses Cyrillic, Arabic, or Chinese script — an IDP becomes much more important. Portuguese police and rental companies may have difficulty reading a non-Latin license, and an IDP provides an official translation. Even so, your original license must accompany the IDP.

Exchanging your license if you become a Portugal resident

If you move to Portugal or plan to stay longer than 12 months, you must exchange your foreign license for a Portuguese license. This is a legal requirement, not optional. You cannot straightforward renew your home license while living in Portugal — you must go through IMTT, the national transport authority.

To exchange your license, you will need to visit an IMTT office in person with your original foreign license, a completed process form (Modelo 01), proof of residence in Portugal (such as a utility bill or rental contract), your passport, and a medical certificate confirming you are fit to drive. The medical certificate must be issued by a doctor authorized by IMTT. Processing typically takes two to four weeks, and the new Portuguese license is valid for 10 years. There is a fee, which varies but is typically €50 to €100.

If your foreign license has already expired, you cannot exchange it — you must retake the Portuguese driving test instead. This is a written test and a practical driving test, similar to the test you took in your home country. Plan for several weeks and multiple test attempts if this applies to you.

Countries whose licenses are not recognized in Portugal

Portugal recognizes licenses from most countries, but a small number of nations are not signatories to the Geneva Conventions and their licenses may not be accepted. These include some countries in Africa, the Middle East, and Central Asia. If your home country is not listed in standard travel resources, contact the Portuguese embassy or consulate in your home country before traveling to confirm whether your license will be recognized.

If your home country's license is not recognized, you will need to obtain an IDP from an international organization or your home country's authority. However, even an IDP may not be accepted in Portugal if your home country is not a signatory. In this case, you may be required to hold a Portuguese provisional license or take a Portuguese driving test. This is rare for travelers from developed nations but does occur.

Common mistakes when driving in Portugal with a foreign license

The most frequent error is carrying only an IDP without the original home license. An IDP is a translation document and has no legal standing on its own — you must have both. Police will not accept an IDP alone as proof of your right to drive.

A second mistake is assuming your license is valid indefinitely. If your home license expires while you are in Portugal, you cannot legally drive, even if you are a visitor. Renew your home license before traveling, or if you are a resident, exchange it for a Portuguese license before it expires.

A third error is not carrying your original documents. Some drivers photograph their license and IDP and leave the originals at their accommodation. Portuguese police will not accept photographs — you must have the physical documents with you in the car at all times.

Frequently Asked Questions

Can I drive in Portugal with an expired license if I have an IDP?

No. An IDP is a translation of your license, not a replacement. If your home license is expired, the IDP is also invalid. You must renew your home license before traveling to Portugal, or if you are a resident, exchange it for a Portuguese license before expiration.

Do I need an IDP if I am only visiting Portugal for a week?

No. Visitors from most English-speaking countries can drive with only their home license for stays under 12 months. An IDP is optional but may be requested by some car rental companies. If you want to avoid any friction with a rental agency, obtaining one before you travel is the safest choice.

What happens if I get stopped by police and do not have my license with me?

You can be fined. Portuguese law requires you to carry your original license at all times while driving. If you cannot produce it, police may issue a fine of €60 to €300 and may impound the vehicle. Always keep your license in the car.

Can I exchange my license for a Portuguese one if I am only visiting?

No. License exchange is for residents only. You must have proof of residence in Portugal, such as a utility bill or rental contract, to exchange a foreign license. Visitors can drive on their home license for up to 12 months without exchanging it.

What if my home country does not issue International Driving Permits?

Some countries do not issue IDPs. If this applies to you, contact the Portuguese embassy or consulate in your home country to confirm whether your home license alone will be recognized. If not, you may need to obtain an IDP through an international automobile association or take a Portuguese driving test.
