To get a Portuguese driver’s license, you either exchange your existing one or pass Portugal’s exams through the IMT (Instituto da Mobilidade e dos Transportes). If you hold an EU, EEA, or UK license, the swap is direct with no tests. If you hold a US license, there’s no nationwide reciprocity agreement, so most Americans must take both the theory and practical driving exams to convert. You’ll need a NIF, proof of residency, and a Portuguese medical certificate before you start.
Key Takeaways:
- EU, EEA, and UK license holders exchange directly at IMT with no exams.
- US citizens face no federal reciprocity, so most states require passing Portugal’s theory and practical tests.
- Residents must exchange a recognized foreign license within 90 days of getting residency.
- Budget roughly $95–$320 (~€90–€300) and 2–6 months, depending on whether you sit exams.
- You’ll need a NIF, residency proof, and a medical certificate first.

Can Americans use a US license in Portugal?
Yes, but only temporarily. As a tourist or visitor, you can drive on your valid US state license, ideally paired with an International Driving Permit, for short stays under the 90/185-day rule. Once you become a legal resident, that clock changes fast. Portuguese law expects residents to convert to a Portuguese license, and you can’t lean on your US license indefinitely.
Here’s the catch I wish someone had told me sooner. The moment you hold a residency permit, you’re no longer a “visitor” in the eyes of the IMT. Residents are generally expected to exchange a recognized license within 90 days of obtaining residency, per Portugal’s official guidance (IMT). For Americans, that window is where the headaches begin, because the US sits in a different category than EU drivers.
Many US relocation guides skip a key nuance: an International Driving Permit doesn’t grant you any conversion rights. It’s just a translation of your home license for short-term driving. Once you’re a resident, the IDP stops mattering and the exchange or exam process takes over.
US citizens can legally drive in Portugal on a valid state license during short visits under the 90/185-day rule, but residents are expected to convert within 90 days of obtaining residency, according to IMT, Portugal’s mobility and transport authority (imt-ip.pt).
If you’re relocating from the States, our guide to moving to Portugal from the USA walks through residency steps that come before any of this.
How do you exchange an EU or UK license in Portugal?
EU, EEA, and UK license holders exchange directly with no exams. This is the smoothest path by far. You submit your existing license, proof of residency, a NIF, and a medical certificate to the IMT, and they reissue a Portuguese license. No theory test, no nervous parallel parking under examiner eyes (ePortugal).
The main rule for EU drivers is timing. You’re expected to register and exchange your license within 90 days of becoming resident, and definitely before your home license expires. UK licenses, post-Brexit, are still recognized for exchange without testing, which is genuinely good news for British retirees up here in the North.
A Dutch neighbour of mine did her exchange in a single IMT appointment after booking online. The paperwork was the slow part, not the process itself. She’d sorted her medical certificate the week before, which saved a second trip.
EU, EEA, and UK driving licenses can be exchanged for a Portuguese one without taking any theory or practical exam, provided the holder meets residency and medical requirements, according to Portugal’s official public services portal (eportugal.gov.pt).
How do US and non-EU drivers exchange a license at IMT?
For US drivers, exchange usually means exams. Portugal has no nationwide reciprocity agreement with the United States, so most state licenses can’t be swapped one-to-one. Instead, the IMT typically requires US holders to pass the theory exam and the practical driving test before issuing a Portuguese license (IMT).
Why the difference? Reciprocity agreements are negotiated country to country, and the US handles licensing at the state level, which makes a single federal deal complicated. Portugal does maintain agreements with some non-EU countries, like Brazil, that allow smoother exchange. The US generally isn’t one of them, so plan for testing.
Don’t assume your specific state changes the outcome. People sometimes hear that a friend from one state had an easier time, but in practice the IMT process for Americans almost always routes through exams. Build your timeline and budget around taking the tests, and treat any shortcut as a pleasant surprise.
You’ll need a NIF before any of this. If you don’t have one yet, start with our step-by-step NIF guide, since the IMT won’t process you without it.
What documents do you need for a Portuguese license?
You’ll need a consistent core set of documents whatever your starting license. The IMT requires your original foreign license, your residency permit or proof of legal residence, your NIF (Portuguese tax number), a Portuguese medical certificate, and a passport-style photo. US applicants taking exams will also register for the theory and practical tests (ePortugal).
- Original valid foreign driver’s license
- Residency document (residence permit or certificate)
- NIF (Número de Identificação Fiscal)
- Portuguese medical certificate (atestado médico)
- Passport or national ID
- Recent passport-style photograph
One practical tip: if your license isn’t in Portuguese or English, IMT may want a certified translation. Services that handle certified document translation for immigration paperwork can turn this around quickly and save you a rejected appointment. For paying IMT and exam fees from a US account without ugly conversion markups, many readers use Wise to hold euros and pay locally.
What are the theory exam and driving test like?
The theory exam is computer-based with multiple-choice road-rules questions, and the practical test is an on-road driving assessment with an examiner. US applicants converting a license usually face both. The theory test can often be taken in English at participating centres, which removes a major worry for Americans, though availability varies by region (IMT).
The theory exam
Expect questions on signage, right-of-way, speed limits, and parking rules. Many applicants register through a driving school (escola de condução), which handles exam booking and gives you practice question banks. Portuguese signage and roundabout etiquette differ from US norms, so a few study sessions genuinely help, even for confident drivers.
The practical driving test
The on-road test checks observation, manoeuvres, and calm decision-making in real traffic. Examiners watch for signalling, mirror checks, and roundabout handling. Speaking of roads, tolls work differently here, so read our Via Verde tolls guide before you start driving regularly.
US license holders converting in Portugal typically sit both a computer-based theory exam and an on-road practical driving test administered through IMT, with the theory test available in English at many centres, according to Portugal’s transport authority (imt-ip.pt).
How long does it take and what does it cost?
Costs and timelines split sharply by license origin. An EU or UK exchange can finish in a few weeks for roughly $95–$160 (~€90–€150) in IMT and medical fees. A US conversion with exams runs longer, often 2–6 months, and $160–$320 (~€150–€300) once you add exam fees and any driving-school lessons. Appointment availability is the biggest variable (ePortugal).
| Factor | EU / EEA / UK exchange | US / non-EU exchange |
|---|---|---|
| Exam required | No | Yes (theory + practical, usually) |
| Typical cost | $95–$160 (~€90–€150) | $160–$320 (~€150–€300) |
| Timeline | 2–6 weeks | 2–6 months |
| Medical certificate | Required | Required |
| Resulting validity | Standard Portuguese license | Standard Portuguese license |
Here’s a rough cost breakdown so you can plan ahead:
| Item | Approx. cost |
|---|---|
| Medical certificate | $30–$55 (~€25–€50) |
| IMT processing/issuance | $35–$65 (~€30–€60) |
| Theory exam (if required) | $30–$45 (~€30–€40) |
| Practical exam (if required) | $35–$55 (~€35–€50) |
| Optional driving lessons | $30–$55 (~€25–€50) each |

How do the medical certificate and IMT appointment work?
You’ll need a Portuguese medical certificate before IMT will issue your license. A licensed doctor performs a basic fitness-to-drive check covering vision and general health, then provides the certificate (atestado médico) you submit with your application. You can arrange this through private clinics or, in some cases, the public health system via SNS 24 resources (SNS 24).
Book your IMT appointment online or in person, bring every document, and don’t skip the photo. For health-system context that ties into the medical step, see our healthcare in Portugal guide.
Here’s the realistic step-by-step timeline:
- Secure your NIF and residency document first.
- Get your Portuguese medical certificate from a licensed doctor.
- Gather documents, including a certified translation of your license if needed.
- Book your IMT appointment online or in person.
- EU/UK holders: submit and collect the reissued license.
- US/non-EU holders: register for and pass the theory exam.
- Pass the practical driving test.
- Pay fees and receive your Portuguese license.
Frequently asked questions
Can I drive in Portugal with a US license?
Yes, temporarily. Visitors can drive on a valid US state license under the 90/185-day rule, ideally with an International Driving Permit. Once you become a resident, you’re expected to convert to a Portuguese license within 90 days, since the IDP and US license no longer cover long-term resident driving, per IMT guidance.
Do Americans really have to take a driving test in Portugal?
In most cases, yes. Because there’s no nationwide US–Portugal reciprocity agreement, the IMT generally requires US license holders to pass both the theory and practical exams to convert. Some non-EU countries have exchange agreements, but the US typically doesn’t, so plan and budget for testing rather than a direct swap.
How long do I have to exchange my license after moving?
Recognized foreign license holders are generally expected to exchange within 90 days of obtaining residency, according to ePortugal. EU and UK drivers should also exchange before their home license expires. Missing the window can complicate your application, so start gathering documents and your medical certificate early to stay comfortably inside it.
Do I need a NIF and medical certificate to apply?
Yes, both. The IMT requires a NIF (Portuguese tax number) and a Portuguese medical certificate for every license application, exchange or exam route alike. Get the NIF first, then book the medical fitness check with a licensed doctor. Without these two items, your IMT appointment can’t be completed, regardless of your nationality.
Final thoughts
Getting a Portuguese driver’s license comes down to which passport you carry. EU, EEA, and UK holders enjoy a clean, exam-free swap that often wraps up in weeks. US citizens face a longer road: no reciprocity, real exams, and a 2-to-6-month timeline that rewards early planning. The good news is the process is predictable once you know the steps.
Start by locking in your NIF, residency document, and medical certificate, then book that IMT appointment. Study the theory bank if you’re American, and treat the practical test like the routine assessment it is. Thousands of expats clear this every year, and so will you. When you’re licensed and on the road, get your tolls sorted next, then enjoy the drive through this beautiful country.
