Exchanging a Foreign Driving Licence in Portugal in 2026 — IMT Categories, the 90- and 185-Day Windows, the Atestado Médico, the Country-by-Country Reciprocity Table, and What Actually Happens at the Espaço Cidadão Counter

Of all the bureaucratic conversions waiting for a new resident in Portugal — fiscal number, social-security number, residence permit, healthcare card — the driving licence is the one that catches the most newcomers off-side. The deadlines are short. They start running from the date your residence is established, not from the date you eventually get round to the paperwork. And missing the window does not get you a fine: it gets you a full Portuguese theory and practical exam in Portuguese, the same one the seventeen-year-olds at any escola de condução sit. This guide walks through how the system works in 2026, what the Instituto da Mobilidade e dos Transportes (IMT) wants in the file, and the actual mechanics at the Espaço Cidadão counter where the licence eventually lands.

The three reciprocity tiers

The IMT splits foreign driving licences into three categories. The category your country sits in determines whether you exchange on paper, exchange after a short administrative validation, or sit a full Portuguese exam.

• Tier 1 — EU/EEA member states plus Switzerland and the United Kingdom. EU and EEA licences are valid in Portugal until they expire. There is no obligation to swap, but most residents do swap eventually because Portuguese road controls and insurance forms run more smoothly with a national document. Practical recommendation: register the licence with the IMT within 185 days of establishing residence, and exchange it before the next renewal cycle. UK licences post-Brexit retain a bilateral agreement that places them inside this same tier.
• Tier 2 — countries with full reciprocity. Brazil, Canada, the United States (state-by-state — see below), Australia, New Zealand, South Africa, South Korea, Japan, Israel, Andorra, Cape Verde, Mozambique, Angola, São Tomé e Príncipe, Macau, Argentina, Chile and a handful of others on the IMT's reciprocity list. These exchange on paper without an examination, but the IMT requires the conversion to be completed within 90 days of establishing residence.
• Tier 3 — countries without reciprocity. Anything not on the IMT list. The licence is not directly exchangeable; the holder must take the Portuguese theory exam (in Portuguese, English, French, or Spanish for the multilingual version) and the practical exam at an IMT-approved escola de condução.

The US state-by-state catch

The United States does not have a federal driving licence and the IMT runs reciprocity at state level. The states with confirmed reciprocity in 2026 are a moving target, but the consistent set includes Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Illinois, Indiana, Iowa, Kansas, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, Tennessee, Texas, Utah, Virginia, Washington, West Virginia and Wisconsin. The list is published on the portal IMT-IP and is the document to check before you start; a licence from a non-reciprocal state — Alabama and Hawaii being the more common surprises — falls into Tier 3 and a full Portuguese exam.

The International Driving Permit (IDP) issued by AAA or your equivalent national motor club is not a substitute for a national licence at exchange time. The IDP is a short-term travel document; the IMT will only act on the underlying state-issued licence. If your US licence has expired before you exchange it, you fall to Tier 3 — the IMT does not exchange expired documents under any reciprocity tier.

The deadlines that catch new residents

• EU/EEA/UK/Switzerland holders: registration recommended within 185 days; exchange at next renewal.
• Tier 2 (full reciprocity, non-EU): exchange must be initiated within 90 days of establishing residence. The clock starts at the issuance date of your residence permit (Título de Residência from AIMA) for non-EU citizens, or at the certificate-of-registration date for EU citizens.
• Tier 3 (no reciprocity): there is no exchange window because there is no exchange. The holder is required to start the Portuguese exam process before driving in Portugal beyond the 185-day visitor allowance under the 1968 Vienna Convention.

Missing the 90-day Tier-2 window does not produce an automatic penalty, but the IMT will refuse the exchange application as out of time and direct the applicant to the standard exam route. There is a discretionary regularisation procedure with the right justification — illness, late issuance of the residence permit, missing documents from the issuing country — and most IMT branches will accept a regularisation file if it is filed within twelve months and supported by paperwork. After twelve months, the discretion narrows considerably.

The documents the IMT needs

• Original foreign driving licence — the physical card, valid (not expired). The IMT will retain the original at the moment of exchange. Some countries require the holder to ask their issuing authority for a release letter — Portugal does this through diplomatic channels in any case, but a pre-emptive release letter speeds the file.
• Certified translation — required if the licence is not in Portuguese, Spanish, French or English, or if the licence uses a non-Latin alphabet (Russian, Arabic, Mandarin, Thai). Translation must be certified by a Portuguese notary, lawyer registered with the Ordem, or the Portuguese consulate in the issuing country. Cost: typically €30-60 depending on length.
• Atestado médico — a medical fitness certificate from a Portuguese GP, ophthalmologist or licensed clinic. The standard form (Modelo 13 IMT) confirms vision, hearing, neurological and cardiovascular fitness. Most clinics — Lusiíadas, CUF, Hospital da Luz, plus a long list of independent clinical practices — issue it in a single appointment for €20-50. Drivers over 60 need a more detailed atestado; over 70, the validity drops to two years.
• Cartão de Cidadão or Título de Residência — for EU citizens, the certificate of registration plus passport; for non-EU citizens, the AIMA-issued residence permit. Names must match across all documents — a recurring snag for applicants whose passports use a maiden name where the residence permit uses a married name, or vice versa.
• NIF — the fiscal number. Required on the application form and for the IMT fee receipt.
• Passport-format photo — biometric, recent, on white background. Most Espaço Cidadão counters have a photo booth on site.
• Modelo 13 — the IMT exchange application form, available at the counter or downloadable from imt-ip.pt.
• Proof of payment — IMT fee currently €30 for the exchange itself. Card payment accepted at all Espaço Cidadão counters.

Where to file: the practical mechanics

Driving-licence exchanges are processed at IMT counters and at most Espaço Cidadão branches under the IMT delegation. The Espaço Cidadão route is the one almost every newcomer ends up using. Booking is through the SIGA platform — the same booking system the rest of the Loja de Cidadão network uses — and the senha appointment is typically available within two to four weeks in Lisbon and Porto, faster outside the metropolitan areas. Walk-ins are accepted at smaller branches but the wait can stretch beyond two hours.

The counter check takes around twenty minutes. The IMT officer verifies the file, retains the original foreign licence, issues a receipt — the guía — that doubles as a temporary licence for sixty days, and uploads the file to the central system. The plastic Portuguese carta de condução arrives by registered post to the address on the residence permit within thirty to forty-five days. The original foreign licence is returned to the issuing country through diplomatic channels and is not handed back to the applicant.

What you cannot do during the wait

The guía — the receipt — is a valid driving document inside Portugal for the sixty days it covers, and inside the EU only by virtue of the Vienna Convention. It is not valid for car hire across borders: rental companies outside Portugal will refuse a guía even within the EU. Plan any cross-border driving against either the original foreign licence (before exchange) or the issued Portuguese carta (after).

Renewal cycles inside Portugal

• Up to age 60: renewal every 15 years for categories B and B1 (private cars).
• From age 60 to 70: every 5 years, with an updated atestado médico at each cycle.
• From age 70: every 2 years, atestado médico becomes a heavier file (vision, neurological, reaction-time tests).
• For categories C, D and E (heavy goods, passenger transport): 5-year cycle, falling to 2 years from age 65.

What it costs end to end

• IMT exchange fee: €30.
• Atestado médico (Modelo 13): €20-50, single visit.
• Certified translation if needed: €30-60.
• Photo: €3-5 at the Espaço Cidadão photo booth.
• Total realistic cost: €55-145 depending on whether a translation is needed.

The exam route — for Tier 3 and missed-deadline cases

If the licence does not exchange, the holder enrols at an IMT-approved escola de condução. The package is a theory exam (currently 30 multiple-choice questions, 27 needed to pass) plus a practical exam with an IMT examiner. The theory is offered in Portuguese, English, French and Spanish; the practical is conducted in Portuguese, with the examiner generally tolerant of English-language exchange where the candidate is otherwise prepared. Cost is the variable. A Lisbon escola de condução package — full course, exam fees, vehicle rental for the practical — runs €700-1,200; rural and small-town escolas come in at €500-900. The practical fail rate sits around 35% on first attempt; second attempts are common and not penalised.

What This Means for You

• If you are EU/EEA/UK: you have time. Register the licence with IMT within the 185-day window for administrative cleanliness, but you do not need to physically exchange until your foreign licence approaches expiry. The exchange at that point is essentially a renewal and avoids any chance of falling out of the system.
• If you are American, Brazilian, Canadian, Australian or from another full-reciprocity country: book your atestado médico in the first 30 days of your residence, file the IMT exchange before day 60. The 90-day deadline will arrive faster than every other deadline you are tracking. Americans should verify their state's reciprocity before booking the medical, because the wrong-state error is the single most common reason an exchange application is refused.
• If your country is not on the reciprocity list: start the escola de condução enrolment within the first month. Expect three to six months from sign-up to a passed practical exam, longer in the larger cities. Drive abroad-issued only inside the 185-day visitor allowance under the Vienna Convention.
• If you have a heavy-goods or passenger-transport licence (C, D, E): the same reciprocity tiers apply, but the medical and the practical exam are weightier. Many exchanges from outside the EU require a CAP — Certificado de Aptidão Profissional — even after the licence itself has been validated, before commercial driving begins.
• If you missed the 90-day window already: file the regularisation request inside twelve months with a written justification and supporting paperwork. Branches in Lisbon, Porto and the Algarve are most familiar with the discretionary procedure.

The forward read

The IMT is in the middle of a digital-procedure rollout that the cabinet flagged in the vehicle-inspection regime modernisation earlier this month, and the licence-exchange flow is on the same upgrade roadmap — a Portal das Cartas portal that would consolidate the application, the medical-certificate upload and the photo capture in a single online flow, with the in-person counter visit reduced to identity verification only. Timeline is uncertain; Q4 2026 is the earliest the cabinet has signalled. Until that arrives, the SIGA-booked Espaço Cidadão slot remains the practical route, and the 90-day window remains the deadline that catches more new residents than any other.
