Portugal is straightforward to drive in once you understand three things that catch visitors out: toll roads, urban parking, and Portuguese priority rules. Vehicles drive on the right, distances and speed limits are in kilometres, and many motorways use electronic toll collection rather than a traditional toll booth.
The rules below apply broadly to visitors, but signs and local restrictions always take priority. Licensing, insurance and rental-company conditions should be checked before collecting a car.

Before you drive in Portugal
Licences and International Driving Permits
Visitors from the EU and European Economic Area can generally drive in Portugal with a valid driving licence issued by their home country. Visitors from other countries can usually drive temporarily with their valid national licence, but the exact rules depend on the issuing country and the driver’s residence status.

An International Driving Permit (IDP) may be required or strongly advisable if your licence is not written in the Latin alphabet or is not easily understood by Portuguese authorities. An IDP is not a replacement for your driving licence: carry both documents. Obtain it from the authorised organisation in your home country before travelling; Portuguese authorities and rental companies do not issue a foreign visitor’s IDP.
#1 Best Overall
Rental companies normally require the physical licence, a passport or national identity card, and a payment card in the main driver’s name. Some apply extra charges or restrictions to drivers under 25, and many require a licence to have been held for at least one year.
Documents and insurance
Carry your driving licence, identification, rental agreement and insurance information. Portuguese law requires third-party liability insurance. A rental car should have the legally required cover, but the excess, tyres, glass, underbody damage, roadside assistance and theft conditions may be separate.
Before leaving the rental depot, photograph the car and record existing scratches, wheel damage and fuel level. Check whether the car is allowed on ferries, on unpaved roads, or across the border into Spain. Cross-border use may require written permission and additional insurance documentation.
Road signs, road position and speed
Portugal drives on the right. Overtake on the left and return to the right lane when it is safe. Traffic signs follow the familiar European system, although local signs, temporary works signs and painted road markings deserve close attention.
Speed limits are posted in kilometres per hour. Unless a lower limit is signed, the commonly used maximums for cars are:
| Road or area | Typical maximum |
|---|---|
| Built-up areas | 50 km/h |
| Non-urban roads | 90 km/h |
| Some reserved or express roads | 100 km/h |
| Motorways | 120 km/h |
These are general limits, not a guarantee that a particular road permits that speed. Signs, weather, road layout and vehicle type can impose a lower limit. Portugal uses fixed and mobile speed enforcement, including on motorways and urban roads. Do not treat the motorway limit as a target in heavy rain, fog or traffic.
Portugal’s toll roads
Tolls are one of the most important practical issues for a rental-car trip. Portugal has conventional toll plazas and motorways equipped only for electronic tolling. On an electronic-toll road, cameras or roadside equipment read the vehicle’s registration number or an onboard device; there may be no booth where you can stop and pay.
Ask the rental company how tolls are handled
Rental companies commonly offer an electronic-toll transponder for a daily fee plus the toll charges. The company may charge the card on file later, sometimes with an administration fee. Ask specifically:
- Whether the car already has a toll transponder;
- Whether you must activate or register it;
- What daily or per-rental service fee applies;
- How toll charges will appear on your final bill;
- Whether the device can be switched off when you use a toll-free route.
Do not assume that declining the transponder makes tolls disappear. Record the registration number and keep the rental agreement. If you use a privately owned car, check the official Portuguese toll-payment options before travelling, because payment arrangements depend on the vehicle’s registration country and the type of toll road.
Google Maps and other navigation apps can be set to avoid tolls, but the toll-free route may be much slower. On a long journey, compare the toll cost with the extra fuel and travel time before choosing.
Intersections, roundabouts and priority
Roundabouts
At a roundabout, give way to traffic already on the roundabout unless signs or markings say otherwise. Approach in the lane indicated by the arrows and use your indicators when changing lanes and when leaving. On a multi-lane roundabout, do not cut across another vehicle to reach an exit.

Drivers unfamiliar with a roundabout should reduce speed before entering rather than stopping unnecessarily on the circle. If you miss an exit, continue around and take another circuit.
Priority from the right
At an unsigned junction, traffic approaching from the right may have priority. Do not assume that the larger road has priority unless a sign or road marking establishes it. A yellow diamond sign indicates a priority road; the crossed-out version indicates the end of that priority.
Give way signs and stop signs apply even when the junction looks empty. At a stop sign, make a complete stop at the line or before entering the intersection.
Traffic lights and pedestrian crossings
Stop at a red light and do not enter an intersection unless your lane is clear. Watch for lights positioned above or beyond the junction. At marked pedestrian crossings, slow down and yield to pedestrians who are crossing or clearly preparing to cross. Never overtake a vehicle stopped at a crossing.

Parking rules change quickly between streets. Blue signs and painted bays commonly indicate paid or controlled parking; payment may be made at a meter, parking terminal or local app. Check the sign at the start of the bay for operating hours, maximum stay and resident restrictions.
Do not park on a pavement, across a dropped kerb, in front of a garage, at a bus stop, on a pedestrian crossing, or where yellow markings prohibit stopping or parking. In narrow historic centres, even a car that physically fits may be blocking emergency access. Use a public car park outside the old town when possible.
In Lisbon and Porto, parking enforcement is active and towing can be inconvenient and expensive. Keep the parking receipt visible if the machine or sign requires it, and do not rely on hazard lights to make an illegal stop acceptable.
Driving on motorways and rural roads
Portuguese motorways are generally well maintained, but rural roads can be narrow, steep and poorly lit. Expect blind bends, stone walls, cyclists, agricultural vehicles and pedestrians. In villages, parked cars may reduce a two-way road to one usable lane.

Leave a large gap at higher speeds and move into a safe place before dealing with navigation. Emergency phones, where provided, can connect you to assistance; otherwise call 112.
Some scenic routes in the Douro Valley, Madeira and the Azores involve sharp gradients and tight bends. Check the rental car’s size before accepting a large SUV. An automatic gearbox can make steep, winding roads easier, but it does not remove the need for low speeds and careful braking.
Seat belts, children and passengers
Seat belts must be worn by occupants in seats equipped with them. Children must use an appropriate child restraint, and the restraint must be installed according to its instructions. Requirements depend on the child’s age, height and weight, so confirm the current Portuguese rule with the rental company or an official source before booking.
Request the correct child seat in advance rather than assuming one will be available at the desk. Check that it is securely fitted before leaving. A rear-facing child seat should not be placed in front of an active passenger airbag.

Holding or manually using a mobile phone while driving is prohibited. Set the route before moving and use a properly mounted hands-free system. A phone stopped at a red light is still a poor place to handle navigation or messages.
Portugal has strict drink-driving rules, with lower limits applying to some novice and professional drivers. The safest choice is not to drive after drinking at all. Cannabis and other impairing drugs can also create criminal and administrative consequences. Do not assume that a small amount is safe or lawful simply because you feel capable of driving.
What to do after a collision or breakdown
Call 112 for an emergency requiring police, medical or fire assistance. Move to a safe location only if it is possible without creating another danger. On a motorway, leave the vehicle from the side away from traffic if necessary and put on a reflective vest if one is supplied.
- Stop and exchange names, contact details, vehicle registrations and insurance information.
- Photograph the vehicles, damage, road position, signs and surrounding conditions.
- Call the rental company’s emergency number and follow its instructions.
- Contact the police when anyone is injured, a driver refuses to exchange details, the vehicles cannot be safely moved, or the circumstances are disputed.
- Do not admit legal fault at the roadside; describe what happened factually.
For a breakdown, use the rental company’s assistance number rather than arranging expensive local recovery without approval, unless there is an immediate safety emergency.

Portugal’s summer heat increases tyre and engine stress. Check tyre pressure, coolant warnings and fuel before taking a long rural route. Keep water in the car, but never leave children or animals unattended in a parked vehicle.
Heavy rain can make roads slippery after a dry period and can cause standing water. In mountainous areas, fog can arrive quickly. Forest-fire restrictions and road closures may affect routes during hot, dry weather; check local warnings before heading into remote areas.
A practical checklist before setting off
- Confirm that your licence and, if needed, IDP are valid.
- Save the rental company’s assistance number and check the insurance excess.
- Ask how the car’s toll transponder works.
- Inspect the car and photograph existing damage.
- Set navigation while parked and choose whether to avoid tolls.
- Check fuel, tyre pressure and the route’s parking arrangements.
- Keep your documents, phone and a payment card accessible without handling them while driving.
FAQ
Can tourists drive in Portugal with a foreign licence?
Usually, yes, for a temporary visit if the licence is valid and recognised. EU/EEA visitors generally use their home licence. Other visitors should check the rule for their issuing country and carry an International Driving Permit when required or advisable, together with the original licence.
Are Portugal’s motorways tolled?
Many are. Some use staffed or card-payment toll plazas, while others use electronic tolling that records the vehicle registration or transponder. Ask the rental company how tolls are billed before leaving the depot.
What side of the road do they drive on in Portugal?
Vehicles drive on the right and normally overtake on the left.
What is the emergency number when driving in Portugal?
Call 112 for police, fire or medical emergencies. For a non-emergency rental breakdown, use the assistance number supplied by the rental company.
The Bottom Line
Driving in Portugal is manageable for visitors who prepare for electronic tolls, read parking signs carefully and slow down on narrow rural roads. Carry the right documents, use the correct child restraints, never drive impaired, and treat local signs and road markings as the final authority.
