Portugal is an excellent country to drive through — the roads are generally well-maintained, distances are modest and scenery ranges from Atlantic coastline to the forested interior of the Alentejo. The biggest surprise for most visiting drivers is the toll system: Portugal has one of the densest motorway toll networks in Europe, and several stretches will charge you automatically with no chance to pay cash at a booth. Plan ahead and the drive is straightforward; ignore the tolls and you may receive an unexpected fine weeks after you get home.
Documents and what to carry
EU/EEA driving licence holders can drive in Portugal on their standard licence. Drivers from outside the EU — including those from the UK, USA, Canada and Australia — should carry an International Driving Permit alongside their national licence. Portugal accepts the 1949 and 1968 Geneva Convention permits; check which your country issues.
The following should be in the car at all times:
- Valid driving licence and vehicle registration documents
- Proof of insurance (green card or equivalent)
- Warning triangle (two are recommended)
- High-visibility safety vest — must be worn if you exit the car on a road after a breakdown
- Hire car agreement, if applicable
If your vehicle is right-hand drive, you will need headlamp beam deflectors to avoid dazzling drivers coming the other way. These are inexpensive and widely available at ferry terminals and motoring shops.
Speed limits
Portugal's standard speed limits are:
- Motorways (auto-estradas): 120 km/h
- Dual carriageways: 100 km/h
- Roads outside built-up areas: 90 km/h
- Built-up areas: 50 km/h; some city centres use 30 km/h zones
Speed cameras — both fixed and mobile — are common on main roads. Portugal also uses average-speed cameras over longer stretches, so maintain a consistent legal speed rather than braking at a fixed camera. Fines can be issued to foreign drivers, and Portugal shares traffic-offence data with EU member states.
The Via Verde toll system
Portugal's motorway tolls are where most foreign drivers get caught out. There are two types of toll payment:
- Traditional booths (portagens): Found on most major routes. You pay by cash or card at staffed or automatic booths — straightforward and familiar.
- Electronic-only (SCUT) roads: Several motorways — particularly in the Alentejo, Beiras and northern Portugal — have no physical toll booths at all. Charges are collected automatically by overhead gantries. If your vehicle does not carry a Via Verde transponder, you must register and pre-pay through a third-party service before you drive, or arrange payment afterwards.
Key risk for hire cars and foreign visitors: If you drive on an electronic-only SCUT road without having pre-arranged payment, the fine will be sent to the vehicle's registered owner — typically the car hire company, which will then charge the fee plus an administrative surcharge to your card, sometimes weeks after your trip. This can add up to far more than the original toll.
The Via Verde electronic tag is the simplest solution. Most Portuguese-registered hire cars already have a Via Verde transponder fitted; if yours does, confirm with the hire company how charges are billed and whether there is a daily fee for using it. If you are driving your own car from abroad, you can purchase or register for a temporary Via Verde through authorised dealers or online services. Alternatively, third-party toll registration services aimed at foreign visitors let you pre-register your number plate and pay online — search for "EASYtoll Portugal" or similar services, and check they cover the specific roads you plan to use.
Motorway tolls: costs and routes
On routes with physical booths, tolls are charged per section and add up over a long journey. Driving from Lisbon to Porto on the A1 motorway — roughly 300 km — costs in the region of €20 in tolls; Lisbon to the Algarve via the A2 is similar. Payment at booths is accepted by card and cash, though some lanes are Via Verde only — look for the green triangle signage.

Rules of the road
Portugal drives on the right. Key points for visiting drivers:
- Alcohol limit: 0.5 g/l blood-alcohol content (BAC). Novice drivers (licence held fewer than three years) face a stricter limit of 0.2 g/l.
- Mobile phones: Hands-free calling is permitted; holding a phone while driving is illegal, including at traffic lights.
- Seatbelts: Compulsory for all occupants front and rear.
- Child seats: Children under 12 and shorter than 135 cm must use an appropriate restraint in the rear seat.
- Roundabouts: Traffic on the roundabout has priority over entering vehicles.
- Horn use: Prohibited within built-up areas except in genuine emergencies.
Fuel and EV charging
Petrol (gasolina), diesel (gasóleo) and LPG are all widely available. Fuel prices are highest at motorway service stations; supermarket forecourts in larger towns are usually cheaper. Many rural filling stations are closed on Sundays, so plan ahead when driving through the interior.
Electric vehicle charging infrastructure has grown steadily, with fast chargers at main service areas on the A1 and A2 corridors and in Lisbon and Porto city centres. Coverage in rural areas and the Alentejo is thinner, so plan your charging stops carefully on cross-country routes.
Parking in Portugal
Parking in city centres is divided into paid zones (usually pay-and-display or pay-by-app), restricted zones (no parking during business hours, marked in yellow) and resident-only areas. Lisbon's historic neighbourhoods have steep, narrow streets and very limited parking; using an underground car park (parque de estacionamento) near your destination is usually easier. In Porto, the city centre is similarly compact — park once and explore on foot or by metro.
Along the Algarve coast in summer, beach parking fills quickly and enforcement is strict. Paid beach parking areas operated by local councils are the safest option; unofficial roadside spots near popular beaches can attract fines or wheel-clamps.
Low-emission zones
Lisbon has introduced low-emission zones in parts of the city centre, with restrictions on older, more polluting vehicles during peak hours. The rules are still evolving; check the current status through Lisbon's municipal website or your navigation app before driving into the centre. Porto has similar plans under development.
Local quirks to know
- Portuguese motorways have frequent, well-signed service areas (áreas de serviço) with cafés, fuel and toilets. Away from motorways, roadside services become much scarcer in rural areas.
- In Lisbon, be ready for trams sharing road space with cars — they move slowly and have absolute priority, and their tracks can be slippery for motorcyclists and cyclists in wet weather.
- Some roads in the Algarve and the mountains of the Serra da Estrela or Gerês have dramatic hairpin bends and passing places — take them slowly and be prepared to reverse to let lorries through.
- Police can issue on-the-spot fines. If you dispute a fine, you may need to pay a deposit before being allowed to continue your journey.
Hiring a car in Portugal
Car hire is widely available at Lisbon, Porto and Faro airports. Confirm with the hire company whether the car has a Via Verde tag and how tolls are billed — some companies charge a daily administration fee of a few euros for the tag, which is usually worth paying to avoid complications on electronic-only roads. For general advice on cross-border hire and what to check in the rental agreement, see our guide to renting a car abroad.
Also note: if you plan to take a hire car from Portugal into Spain or another country, you need to inform the hire company in advance. Most companies permit this on standard agreements, but some budget providers do not.
Frequently asked questions
What is Via Verde and do I need it in Portugal?
Via Verde is Portugal's electronic toll system. On motorways with physical booths you can pay by cash or card without it. However, on several motorways with no booths at all — particularly in central and northern Portugal — you must either have a Via Verde tag, pre-register your number plate, or use a third-party payment service before you drive. Driving through without prior arrangement leads to fines billed via the hire company or sent directly.
Can I drive in Portugal on a UK or US licence?
UK licence holders can drive in Portugal without an IDP. US, Canadian and Australian licence holders are advised to carry an International Driving Permit alongside their national licence, though requirements can change — confirm with your government's travel advice before travelling.
What is the speed limit on Portuguese motorways?
The general limit on motorways (auto-estradas) is 120 km/h in dry conditions. Average-speed cameras enforce limits over extended stretches on some routes.
Is Portugal cash-friendly for toll payments?
At traditional toll booths, yes — cash and card are both accepted. But a growing number of motorway sections have no booths and are electronic-only, so cash is not an option on those stretches. Always check your planned route before setting off.
