Traffic Rules in Portugal — Road Laws & Speed Limits

Driving Basics

Portugal uses right-hand traffic — vehicles drive on the right side of the road and overtake on the left. If you are from a left-hand-driving country (such as the UK, India, or Pakistan), this is one of the biggest adjustments you will need to make.

• You must carry your driving license, vehicle registration document (DUA), and proof of insurance at all times while driving.
• Headlights must be on at all times on motorways and main roads, and in tunnels.
• A reflective vest and a warning triangle are mandatory equipment in every vehicle.
• The use of radar detectors is illegal.

Speed Limits

Speed limits in Portugal are measured in kilometres per hour (km/h). The standard limits for passenger cars (Category B) are:

• Urban areas (dentro de localidades): 50 km/h
• Rural roads (estradas nacionais): 90 km/h
• Motorways (autoestradas): 120 km/h

Lower limits apply in specific situations:

• School zones: Typically 30 km/h — always follow posted signs.
• Novice drivers (probationary license): Maximum 90 km/h on rural roads and 100 km/h on motorways.
• Vehicles towing trailers: Reduced limits apply. Check posted signs and current regulations.

Seatbelt Requirements

Seatbelts are mandatory for all vehicle occupants — driver and all passengers, front and rear. Failure to wear a seatbelt results in a fine. The driver is responsible for ensuring all passengers under 18 are properly restrained.

Child Car Seat Rules

Portugal requires appropriate child restraint systems for children under 12 years old and under 135 cm in height:

• The type of child seat (rear-facing, forward-facing, or booster) depends on the child's weight and height.
• Children must travel in the rear seats. They may only sit in the front seat if the rear seats are already occupied by other children in restraints, or if the vehicle has no rear seats — in which case, the front airbag must be deactivated.
• It is illegal to carry a child in a rear-facing seat in the front if the passenger airbag is active.

Alcohol Limits

Portugal enforces strict drink-driving laws:

• General limit: 0.5 g/L blood alcohol concentration (BAC).
• Novice drivers (probationary period) and professional drivers: 0.2 g/L BAC.
• BAC 0.5–0.8 g/L: Serious traffic offence. Fine and points deduction.
• BAC 0.8–1.2 g/L: Very serious offence. Higher fine, license suspension, and points deduction.
• BAC above 1.2 g/L: Criminal offence. This can result in a criminal record, license suspension, and imprisonment.

Mobile Phone Use

Using a hand-held mobile phone while driving is illegal in Portugal. This includes talking, texting, or holding the phone in any way while the vehicle is in motion or stopped in traffic.

• Hands-free devices (Bluetooth earpiece, dashboard-mounted phone with voice control) are permitted.
• Fines for mobile phone use while driving are substantial and carry points deductions.

Roundabout Rules

Roundabouts (rotundas) are extremely common in Portugal. The rules are:

• Give way to the left: Vehicles already circulating in the roundabout have priority. You must yield to traffic coming from your left before entering.
• Lane selection: Use the right lane if you are taking the first or second exit. Use the inner (left) lane for exits further around the roundabout.
• Signalling: Signal right when you are about to exit the roundabout.
• Stay in your lane: Do not change lanes inside the roundabout unless it is safe and you signal.

Motorway Rules

Portuguese motorways (autoestradas, marked with “A” followed by a number) have specific rules:

• Minimum speed on motorways is generally 50 km/h — vehicles that cannot maintain this speed are not allowed.
• Keep to the right lane except when overtaking.
• Overtaking on the right is illegal.
• Headlights must be on at all times on motorways.
• Emergency lane (berma) is for emergencies only — never use it for driving or overtaking.
• Pedestrians, cyclists, mopeds, and vehicles under 50cc are not permitted on motorways.

Parking Rules & Zones

Parking in Portuguese cities follows a colour-coded zone system:

• Blue zones: Paid parking during posted hours (typically weekdays). Buy a ticket from a parking meter (parcómetro) or use a mobile payment app.
• Yellow lines or zones: No parking at any time.
• White zones: Free parking (no time restriction), though these are rare in city centres.
• Resident zones: Some areas are reserved for residents with permits.

Illegal parking can result in a fine or your vehicle being clamped (bloqueado) or towed. Always check signage before parking.

Priority & Pedestrian Rules

• Priority to the right: At unmarked intersections, traffic coming from the right has priority.
• Pedestrian crossings: Drivers must stop for pedestrians at marked crossings (passadeiras). Failure to do so is a serious offence.
• School zones: Speed is typically limited to 30 km/h near schools. Be especially cautious during school hours.
• Emergency vehicles: You must yield and make way for emergency vehicles with lights and sirens active.
• Trams: In Lisbon and Porto, trams have priority. Never block tram tracks.

Fines & Penalties

Traffic fines in Portugal are categorised by severity:

• Leve (minor): Smaller fines for less serious offences.
• Grave (serious): Higher fines and potential points deduction.
• Muito grave (very serious): Largest fines, points deduction, and potential license suspension.

Fines are set by the Código da Estrada and updated periodically. Check the ANSR website for current fine amounts. Common offences include:

• Speeding
• Drink-driving
• Mobile phone use
• Running red lights
• Not wearing a seatbelt
• Illegal parking
• Not stopping at pedestrian crossings

Points Deduction System

Portugal operates a points-based license system (carta por pontos). Drivers start with a set number of points, and offences result in deductions:

• The number of points deducted depends on the severity of the offence.
• If all points are lost, your license is suspended.
• Points are restored over time if no further offences are committed.
• Attending an approved road safety course can restore some points.
• Check your current points balance through the IMT website or at an IMT office.

Towing & Vehicle Impound

Your vehicle can be towed or impounded in the following situations:

• Parked illegally, blocking traffic or emergency access
• Driving without valid insurance
• Driving under the influence above criminal thresholds
• Driving with a suspended or revoked license
• Vehicle has no valid inspection (IPO) and is deemed unsafe

Recovering a towed vehicle involves paying the towing fee plus a daily storage charge. Check with your local municipality or police for the recovery process.

Common Questions

What is the alcohol limit for drivers in Portugal?

The general blood alcohol limit is 0.5 g/L. For novice drivers (those in their probationary period) and professional drivers, the limit is stricter at 0.2 g/L. Exceeding these limits results in fines, points deduction, and potential license suspension.

Do children need car seats in Portugal?

Yes. Children under 12 years old and under 135 cm in height must use an appropriate child restraint system (car seat or booster). The type of restraint depends on the child's weight and height. Children must ride in the back seat unless the front passenger airbag is deactivated.

Can I use my phone while driving in Portugal?

Holding or using a mobile phone in your hand while driving is illegal in Portugal. Hands-free systems (Bluetooth, dashboard mount with voice control) are permitted. Fines for phone use while driving are significant.

How do roundabouts work in Portugal?

Traffic already inside the roundabout has priority. You must give way to vehicles approaching from your left. Use the right lane for the first or second exit, the left lane for later exits, and signal when leaving the roundabout.

What are the speed limits in Portugal?

For cars: 50 km/h in urban areas, 90 km/h on rural roads (estradas nacionais), and 120 km/h on motorways (autoestradas). Lower limits apply to novice drivers, vehicles with trailers, and heavy vehicles. Always check posted signs as local limits may differ.
