What you actually need to drive in Portugal
You do not need an international driver's license to drive in Portugal if you hold a valid driver's license from another country. Portugal recognizes licenses issued by any EU or EEA country without restriction. If your license comes from outside the EU or EEA — the United States, Canada, Australia, or most other nations — you can drive on your home country license for up to 12 months as a visitor.
An International Driving Permit (IDP) is not required by Portuguese law. However, it can be useful as a translation and backup document if you are stopped by police or need to rent a car. Some car rental companies ask for one, though most do not. The permit is issued by your home country's automobile association or licensing authority and costs between $15 and $30 depending on where you obtain it.
Key Takeaways
- Your home country driver's license is legally sufficient to drive in Portugal for up to 12 months if you are a visitor.
- An International Driving Permit is optional and not required by Portuguese law, but some car rental companies prefer to see one.
- If your license is not in Latin characters, carrying an IDP alongside your original license removes confusion at police stops.
- If you plan to stay longer than 12 months, you will need to exchange your foreign license for a Portuguese one through the Instituto da Mobilidade e dos Transportes Terrestres (IMTT).
When a rental company will ask for an International Driving Permit
Most major car rental chains in Portugal — Hertz, Avis, Enterprise, and Europcar — do not require an International Driving Permit if you show a valid home country license. However, some smaller local rental companies and certain insurance policies tied to the rental may request one as a condition of the contract.
The safest approach is to obtain an IDP before you travel if you plan to rent a car. It takes 10 to 15 minutes to obtain one in person from your country's automobile association (AAA in the United States, CAA in Canada, RACV in Australia) and costs little. If you arrive without one and a rental company requires it, you cannot obtain one in Portugal — you would need to arrange it through your home country's association and have it mailed to you, which defeats the purpose of renting when ready.
How to get an International Driving Permit before you travel
In the United States, visit your local AAA office or order online through AAA.com. You will need your valid driver's license, a passport-sized photo, and the process form (Form DS-11 or equivalent). The permit costs $20 and is valid for three years. Processing takes one business day in person or five to seven business days by mail.
In Canada, contact the Canadian Automobile Association (CAA) provincial branch in your province. You will need your valid driver's license, proof of Canadian residency, and a completed process. The cost is $35 CAD and the permit is valid for one year. In Australia, visit the RACV office or order through their website; the cost is $20 AUD and the permit is valid for one year.
In the United Kingdom, the AA and RAC both issue International Driving Permits. You will need your valid UK photocard license and a completed process. The cost is £5.50 and the permit is valid for one year. Most other countries have a similar process through their national automobile association or licensing authority.
What happens if your license is not in Latin characters
If your driver's license uses Cyrillic, Arabic, Chinese, or any non-Latin script, carrying an International Driving Permit alongside your original license is strongly recommended. Portuguese police can read Latin characters but may struggle with other alphabets, and an IDP provides an official translation that removes doubt during a traffic stop.
Even without an IDP, your original license remains valid — Portugal does not require a translation by law. However, a rental company may refuse to rent to you without an IDP if they cannot verify the information on your license. The IDP solves this problem and costs so little that it is worth obtaining before you travel.
Staying longer than 12 months: exchanging your license
If you become a resident of Portugal and plan to stay longer than 12 months, you must exchange your foreign driver's license for a Portuguese one. You cannot straightforward renew your home country license while living in Portugal — Portuguese law requires residents to hold a Portuguese license.
To exchange your license, contact the Instituto da Mobilidade e dos Transportes Terrestres (IMTT), which is Portugal's national licensing authority. You will need your original foreign license, proof of residency in Portugal (a utility bill or rental agreement), your passport, and a completed process form. The process takes two to four weeks and costs approximately €50 to €70. You do not need to take a driving test if your foreign license is valid and was issued by an EU, EEA, or recognized country.
What to carry when you drive in Portugal
Portuguese law requires you to carry your original driver's license at all times while driving. If you have an International Driving Permit, carry it alongside your original license. You must also carry your vehicle registration documents, proof of insurance, and a valid passport or national ID card.
Police can stop you at any time and ask to see these documents. If you cannot produce your original license, you may face a fine even if you have an IDP. The IDP is a supplement, not a replacement. Keep both documents in an easily accessible place in your vehicle.
Frequently Asked Questions
Can I drive in Portugal with just an International Driving Permit and no home country license?
No. An International Driving Permit is only valid when carried alongside your original home country driver's license. Portuguese police will not accept an IDP alone. You must have both documents.
Do I need an International Driving Permit if I am driving through Portugal for just a few days?
No, it is not required by law. Your home country license is sufficient. However, if you are renting a car, check with the rental company in advance — some prefer to see an IDP even for short rentals, and it is easier to obtain one before you travel than to arrange it while abroad.
What if my home country license has expired but I am still within the 12-month visitor window?
Your license must be valid to drive legally in Portugal. An expired license is not valid, even if you are still within the 12-month visitor period. You must renew your license through your home country before driving in Portugal.
Can I get an International Driving Permit in Portugal if I did not bring one?
No. An International Driving Permit can only be issued by your home country's automobile association or licensing authority. Portugal does not issue them. If you need one after arriving, you would have to arrange for it to be mailed to you from your home country, which typically takes one to two weeks.
Is an International Driving Permit the same as a Portuguese driver's license?
No. An International Driving Permit is a temporary translation document valid for one to three years depending on your country. A Portuguese driver's license is a permanent license issued by the IMTT and required if you become a resident. They serve different purposes.
