Driving in Portugal as an Expat: Licences, Rules, and What Catches People Out
Can you use your foreign driving licence in Portugal? How long before you need to convert it? Speed limits, tolls, and the rules that trip up expats most often.
Driving in Portugal is generally straightforward — the roads are good, traffic outside Lisbon and Porto is manageable, and the rules largely align with the rest of continental Europe. But there are specifics that trip up expats, particularly around licence validity and the toll system.
Using Your Foreign Driving Licence
EU/EEA licences: Valid indefinitely in Portugal. No conversion needed as long as your licence is valid. When it expires, you renew in Portugal through the IMT (Instituto da Mobilidade e dos Transportes).
UK licences (post-Brexit): Valid for driving in Portugal for up to 185 days per year as a visitor. Once you establish Portuguese residency, you have 90 days to convert your UK licence to a Portuguese one. The conversion process requires an eye test, a visit to the IMT, and a fee of approximately €30. No driving test required for direct conversion.
Non-EU licences (US, Canadian, Australian, etc.): Valid for up to 185 days from entry as a tourist. Once resident, you have 90 days to either convert (if your country has a reciprocal agreement — the US does not) or take the full Portuguese driving test. Countries with reciprocal agreements include Switzerland, Brazil, and several others — check the IMT website for the current list.
US licence holders: No reciprocal agreement means you must take the theory test (available in English) and a practical driving test. Many expats use a driving school for 3-5 refresher lessons before the practical. Cost: €300-600 total including school and tests.
Speed Limits
- Motorways (autoestradas): 120 km/h
- Dual carriageways (vias rápidas): 100 km/h
- Outside built-up areas: 90 km/h
- Built-up areas: 50 km/h (30 km/h in some urban zones)
Speed cameras are widespread and actively enforced. Mobile units are also common on national roads. Fines start at €60 for minor speeding and can reach €2,500 for serious violations. Points are deducted from your licence — once resident, your Portuguese licence is the reference.
The Toll System (This Catches Everyone)
Portugal's motorway toll system is almost entirely electronic — there are very few traditional toll booths. The system uses overhead gantries that read number plates and/or transponders.
If you have a Portuguese-registered car: Set up a Via Verde transponder or register your plate for automatic billing. This is the simplest long-term solution.
If you're in a foreign-registered car or rental: You must register at a CTT (post office) or Payshop within 5 days of using a toll road, or pre-register your plate online at portugaltolls.com. Many rental companies charge an administrative fee for this — check your rental agreement.
Unpaid tolls attract fines of €25-500. Foreign-registered cars are traced through EU licence plate sharing agreements — not paying is not a reliable strategy.
Insurance
Third-party insurance (seguro de responsabilidade civil) is mandatory for all vehicles. If you're importing a car from another EU country, your existing EU insurance is valid temporarily but you'll need a Portuguese policy once resident. Brokers like Tranquilidade, Fidelidade, and Allianz Portugal are standard options. Online comparison tools (comparaja.pt) are useful for getting quotes.
What Else Catches Expats Out
- No right turn on red — unlike the US, this is not permitted unless explicitly signed
- Roundabout priority — traffic already on the roundabout has priority (same as UK, opposite to some countries)
- Mandatory equipment: Reflective vest, warning triangle, and spare wheel or tyre repair kit required in all vehicles
- Blood alcohol limit: 0.5g/L (lower than UK's 0.8g/L). Zero tolerance for drivers with less than 3 years' experience
- Phone use: Hands-free only. Fines from €120
