What an International Driving Permit Does in Portugal
An International Driving Permit (IDP) is a document that translates your home country's driver's license into multiple languages. It is not a separate license — it works only alongside your original license, and Portugal will accept it as proof you can drive legally.
Portugal recognizes IDPs issued by your home country's motor vehicle authority. If you are visiting Portugal or moving there temporarily, an IDP lets you rent a car and drive without needing to convert your license to a Portuguese one. Police and rental companies understand it when ready, which avoids confusion at checkpoints or rental desks.
If you plan to stay in Portugal permanently or work there, you will eventually need to exchange your home license for a Portuguese one instead — an IDP is not a long-term solution for residents.
Key Takeaways
- An International Driving Permit is issued by your home country's motor vehicle authority before you travel, not in Portugal.
- You must carry both your original home license and the IDP together — the permit alone is not valid.
- Portugal honors IDPs for temporary visitors and short-term stays, but permanent residents must exchange their license for a Portuguese one.
- The IDP process, cost, and processing time depend entirely on your home country's rules, not Portugal's.
How to Get an IDP Before You Travel to Portugal
You obtain an IDP from the motor vehicle authority in your home country, not from Portugal. In the United States, this is the American Automobile Association (AAA) or your state's Department of Motor Vehicles. In Canada, it is the provincial motor vehicle office. In the United Kingdom, it is the DVLA. Each country has its own process and fee.
The basic steps are the same everywhere: you provide your valid home driver's license, a passport-sized photograph, proof of citizenship, and payment. Processing usually takes one to two weeks, though some countries offer expedited service for an extra fee. You will receive a booklet that translates your license information into French, Spanish, German, and other languages — all recognized in Portugal.
Start this process before you book your trip. If you are moving to Portugal, obtain the IDP before you leave your home country, because getting one after you arrive is difficult and slow.
What You Need to Carry When Driving in Portugal
Portugal requires you to carry both your original home driver's license and your International Driving Permit together at all times while driving. Neither document alone is sufficient. You must also carry your passport or national ID card, proof of vehicle insurance, and the vehicle registration document.
Police checkpoints are common on Portuguese highways, especially near the Spanish border and in Lisbon. Officers will ask for all documents. If you have only the IDP and not your home license, or vice versa, you can be fined. Keep both documents in the same place — your glove compartment or a travel document folder — so you do not accidentally leave one behind.
How Long an IDP Is Valid in Portugal
An International Driving Permit is valid for one year from the date of issue in most countries. Portugal honors this one-year validity period. If your IDP expires while you are in Portugal, you cannot legally drive — you must either renew it through your home country's motor vehicle authority (which requires mailing documents back home) or stop driving until you can obtain a new one.
If you are planning a stay longer than one year, check your home country's rules on renewing an IDP while abroad. Some countries allow postal renewal; others require you to renew in person. Plan ahead so your permit does not expire mid-stay.
When You Need to Exchange Your License for a Portuguese One
If you become a resident of Portugal — meaning you register with the local municipality and establish permanent address — you must exchange your home driver's license for a Portuguese license within a set timeframe. The exact important date varies by region but is typically six to twelve months after establishing residency.
To exchange your license, you will visit the Instituto da Mobilidade e dos Transportes Terrestres (IMTT), Portugal's road transport authority. You will need your home license, your IDP, proof of residency, a medical certificate, and proof of payment of the exchange fee. The process takes several weeks. During this time, you can still drive on your home license and IDP, but once your Portuguese license is issued, you must use it instead.
An IDP does not count as a Portuguese license and will not satisfy residency requirements. Do not delay the exchange process if you have settled in Portugal.
Renting a Car in Portugal With an IDP
Car rental companies in Portugal accept an International Driving Permit as long as you also have your original home license. When you arrive at the rental desk, present both documents along with your passport and a credit card for the deposit.
Some rental companies require you to be at least 21 years old; others require 25. A few charge a young driver fee if you are under 25. These rules are set by the rental company, not by Portugal's government. Check the rental company's website before you book, because policies vary widely between Lisbon, Porto, and smaller cities.
If you are renting a car, also purchase third-party liability insurance through the rental company or your home insurance provider. Portugal requires all drivers to carry proof of insurance at all times.
What Happens If You Drive Without an IDP
If you are stopped by police and cannot produce both your home license and your IDP, you can be fined. The fine amount depends on the officer's judgment and the specific circumstances, but it is not a small penalty. You may also be unable to rent a car if you cannot show the rental company that you have the proper documents.
If you are involved in an accident, your insurance claim may be delayed or denied if you cannot prove you were legally authorized to drive. This is why carrying both documents is not optional — it is a legal requirement.
Frequently Asked Questions
Can I drive in Portugal on just my home license without an IDP?
No. Portugal requires both your home license and an International Driving Permit. Your home license alone is not recognized. You must obtain the IDP from your home country's motor vehicle authority before you travel.
How much does an International Driving Permit cost?
The cost varies by country. In the United States, AAA charges around $20. In Canada, provincial fees range from $15 to $30. In the UK, the DVLA charges around £5.50. Check your home country's motor vehicle authority for the exact fee.
Can I get an IDP in Portugal if I forgot to get one before I traveled?
No. Portugal does not issue IDPs. You must obtain one from your home country's motor vehicle authority. If you are already in Portugal without one, you cannot legally drive. You will need to contact your home country's authority to arrange postal delivery or ask someone at home to obtain one for you.
Is an International Driving Permit the same as a Portuguese driver's license?
No. An IDP is a translation document that works alongside your home license. A Portuguese license is a separate document issued by Portugal's road transport authority. If you become a resident, you must exchange your home license for a Portuguese one — the IDP will no longer be valid.
What if my IDP expires while I am living in Portugal?
If you are a temporary visitor, you cannot legally drive once your IDP expires. If you are a resident, you should have already exchanged your home license for a Portuguese one, so the expiration of your IDP does not matter. If you are a resident and still holding only an IDP, you must stop driving until you complete the license exchange process.
