Car Seat Laws in Portugal: What Every Family Needs to Know
Updated: Aug 25
Portuguese child restraint law applies the same way whether you're navigating Lisbon's hills, driving the A22 along the Algarve coast, or catching taxis in Porto — and it draws a clear, nationwide line between private vehicles and taxis that's worth understanding before you arrive. Whether you're flying into Lisbon, Porto, or Faro, hiring a car for a longer trip, or relying on taxis and ride-share apps, knowing exactly where that line falls shapes how you should plan transport for your children.
The Legal Requirement
Portugal's child restraint rules are set out in Article 55 of the Código da Estrada (Portuguese Highway Code). Under this article, any child under 12 years old or shorter than 135 cm — whichever threshold is reached first — must use a child restraint system appropriate to their age, height, and weight. The requirement applies fully to private vehicles and rental cars throughout the country, from the Algarve to the Minho.
The seat type required follows the child's weight. Infants up to 13 kg travel rear-facing. Children from 9 to 18 kg use forward-facing seats with a harness. Children from 15 to 36 kg use booster seats until they clear 135 cm in height. Seating position is also specifically regulated: children under 3 may never sit in the front seat, even with a restraint fitted, and children 3 and older may only sit in front with an appropriate seat, and only when the rear seats are already occupied by other children in restraints. All seats must meet ECE R44 or the newer R129 (i-Size) standard. For the official text, see Article 55 of the Código da Estrada via the Diário da República. The Autoridade Nacional de Segurança Rodoviária (ANSR) publishes detailed national guidance on compliance and installation.
How It Applies to Taxis
Taxis across Portugal operate under a exemption Under Article 55 that exemption applies only when the child travels in a rear seat. Portugal also extends it to TVDE ride-hailing vehicles such as Uber and Bolt, which is unusual — in most EU countries ride-hailing sits outside the taxi exemption entirely. from the child restraint requirement under Article 55. This exemption is nationwide and unconditional — it applies the same way in Lisbon, Porto, Faro, or anywhere else in the country, regardless of trip distance or whether the journey is within a city or between regions. Ride-share and TVDE platforms operating in Portugal, including Uber and Bolt, fall under the same exemption as licensed taxis.
One condition carries over within the exemption: children 3 and older must wear the available seatbelt if no restraint is fitted in the taxi. Children under 3 may legally travel without any restraint if none is available — this is the law's stated position rather than an informal practice.
Most standard taxis across Portugal do not carry child seats as routine equipment, though a small number of larger vehicles in Lisbon and Porto occasionally do at the driver's own discretion rather than as a legal requirement. For airport transfers from Lisbon, Porto, or Faro, or any journey of meaningful length, pre-booking a transfer with a confirmed, fitted seat is the only reliable way to give your child genuine protection beyond the legal minimum.
How It Applies to Rental Cars
The taxi exemption does not extend to rental cars, nor to private transfer companies and tour operators using standard private vehicles — both are treated as fully subject to Article 55. Full compliance is mandatory from the moment you collect a rental vehicle at Lisbon, Porto, or Faro airport, and you bear personal responsibility as the driver for ensuring every child under 12 and under 135 cm is correctly restrained.
Major rental companies across Portugal offer child seats as an add-on, but they should be reserved well ahead, especially during the summer peak season along the Algarve. Seat condition can vary — some older R44-standard seats remain in circulation and are technically legal, but not always in ideal condition.
Confirm the seat type and your child's current weight category in writing at booking, and inspect the seat before driving away. For infants, or for a longer road trip toward the Douro Valley or the Algarve coast, bringing your own seat from home removes that uncertainty.
Fines and Penalties
Transporting a child without the required restraint in a private or rental vehicle in Portugal is treated as a serious offence under the Código da Estrada. The PSP and GNR conduct active roadside checks nationwide, with particular focus on motorways and near tourist hubs such as Lisbon, Porto, and the Algarve.
Fines for non-compliance range from €120 to €600 per child transported without proper restraint. For current official fine details, refer to the Autoridade Nacional de Segurança Rodoviária (ANSR) or the Diário da República for the full legal text.

FAQ
• Do I need a car seat for my child in a Portuguese taxi?
Legally, no. Taxis throughout Portugal have a exemption from the child restraint requirement under Article 55 of the Código da Estrada, and this applies nationwide regardless of trip length — it is not limited to short or urban journeys. Children 3 and older must wear the available seatbelt if no restraint is fitted; under-3s may travel without any restraint if none is available.
Under Article 55 that exemption applies only when the child travels in a rear seat. Portugal also extends it to TVDE ride-hailing vehicles such as Uber and Bolt, which is unusual — in most EU countries ride-hailing sits outside the taxi exemption entirely.
• Does the taxi exemption in Portugal apply to Uber and Bolt?
Yes. Ride-share and TVDE platforms, including Uber and Bolt, are covered by the same exemption as licensed taxis. Neither service is legally required to provide a car seat, and in practice neither reliably does so.
• What age or height ends the car seat requirement in Portugal?
Either threshold ends it, whichever your child reaches first: 12 years old or 135 cm in height. A tall child who passes 135 cm before turning 12 may use a standard seatbelt.
• What's the fine for not having a car seat in a Portuguese rental car?
Fines range from €120 to €600 per child transported without the proper restraint. Portuguese police actively enforce this rule, particularly on motorways and around major tourist regions including Lisbon, Porto, and the Algarve.
• Can I book a taxi with multiple child seats for an airport transfer in Portugal?
Yes. Taxibambino.com lets you specify the number and type of seats — infant, forward-facing, or booster — when booking your transfer from Lisbon, Porto, Faro, or anywhere in Portugal. The seats are confirmed and fitted before pickup, which matters given that standard taxis have no legal obligation to provide one.

Portugal's exemption covers TVDE ride-hailing as well as licensed taxis — unusual in Europe — but only when the child travels in a rear seat, per Article 55 of the Código da Estrada. Independently of the law, the physics are unchanged: a seat approved to the applicable standard and fitted on rigid ISOFIX anchors holds its line where a belt-only fit works loose — particularly on the A22 Via do Infante, the A5 to Cascais and the VCI ring at Porto.
Space is the other constraint our drivers meet at the airport rank, which is filled largely with compact and mid-sized cars: two bulky seats plus a double stroller and the luggage already fills one, so a third child needing a restraint means booking a larger vehicle in advance.
What our own booking data shows: across 1027 bookings made through TaxiBambino across 5 destinations in Portugal in the twelve months to August 2026, the middle half of families paid roughly €40–€74, with a median near €51. Party size is the part most families underestimate: 30% of those bookings were for four or more passengers and 12% for five or more — the point at which a standard sedan stops working once car seats, a stroller and luggage are added.
September was the busiest travel month, and families booked around five days ahead on average. Prices move with demand, season and the specific route, so treat these as historical ranges rather than a quote; vehicles are supplied by TaxiBambino and our partner network.
