Car seat rules in Europe
Built from GOV.UK, the EU's Your Europe road rules pages and each country's own government or highway code pages, checked October 2026. Rules change, so check again before you drive.
Key facts
Short answer: child car seats are compulsory in every European country we checked, so your baby always needs an approved seat, but the age and height limits differ. The UK rule is 12 years or 135 cm. Spain and the Netherlands use 135 cm, Italy uses 150 cm, Germany uses under 12 and under 150 cm, France uses under 10, and Ireland uses under 150 cm or 36 kg. Wherever we found an airbag rule (the UK, France, Italy, Ireland and the Netherlands), a rear-facing baby seat can't go in front of an active airbag. Taxi rules are looser and vary, so for a baby it's safest to book a transfer that confirms a seat, or bring your own.
Quick answers
- Can I use my UK car seat in Europe? France and the Netherlands name the same approvals as the UK (R129, or ECE R44/03 and R44/04), and Ireland accepts R129 seats and R44 seats bought before September 2024, so a UK seat with one of those labels meets their rules.
- Do babies need a car seat in a European taxi? It depends on the country. France exempts taxis, while Italy only lets a child skip the seat if they're not in a front seat and travel with someone aged 16 or over. Our advice for a baby is to book a transfer with a seat, or bring yours.
- Can my baby sit in the front? Only rear-facing with the airbag switched off. France and Spain otherwise want young children in the back unless the rear seats are full of other children or the car has none.
- Will a hire car come with a child seat? GOV.UK says car hire firms in Spain can provide child seats if you ask when you book. Wherever you hire, ask for one when you book and check it when you collect the car.
- Which countries have the strictest height limit? Of those we checked, Italy, Germany and Ireland use 150 cm, which is taller than the UK's 135 cm.
- Does my baby need to face backwards? In the UK and Ireland, height-based (R129) seats must stay rear-facing until a child is over 15 months, and Ireland's road safety authority says at least 15 months for any seat.
Rules by country
| Country | Who needs a child seat | Front seat | Taxis | Source |
|---|---|---|---|---|
| UK | Until 12 years old or 135 cm, whichever comes first | Rear-facing seat only with the front airbag off | Without a seat, children ride in the back (under 3s without a belt) | GOV.UK |
| France | Under 10, unless the child is big enough for the belt (seats are designed up to 1.50 m) | Under 10s ride in the back, except a rear-facing baby seat with the airbag off, or if the rear seats are full of under 10s or missing | Exempt | Service Public |
| Spain | Under 1.35 m, in an approved seat on the back seat | Only if the rear seats are taken by other children or there are none | Under 1.35 m need no seat belt on the back seat, on urban roads only | GOV.UK, Your Europe |
| Italy | Under 1.50 m, in an approved seat suited to their weight | No rear-facing seat in front of an active airbag | May skip the seat if not in a front seat and with a passenger aged 16 or over | Codice della strada, art. 172 |
| Germany | Under 12 and under 150 cm | Not stated in the rule we read | Must be able to seat two children of 9 kg or more | StVO §21 |
| Ireland | Under 150 cm or 36 kg | No rear-facing seat in front of an active airbag | Exempt | Road Safety Authority |
| Netherlands | Under 1.35 m, front or back | A baby seat in front only with the airbag off | Exceptions apply | Rijksoverheid |
Portugal, Greece and Croatia: the EU's Your Europe pages say child restraints are compulsory in all three, but we couldn't read the exact limits on an official page in English or in a format our checks could open, so confirm them with your hire firm.
France
Service Public, the French government's information site, says a child under 10 must travel in the back in an approved child seat suited to their size and weight. A child under 10 can only sit in the front if they're in a rear-facing baby seat with the airbag switched off, if the car has no rear seats or no rear seat belts, if the rear seats can't be used for the moment, or if other children under 10 already fill every rear seat.
A child seat isn't required if the child is already big enough to wear the seat belt properly (seats are designed for children up to 1.50 m), if they have a medical exemption certificate, or if they're in a taxi or on public transport. The fine for breaking the rules can be up to €750, and is usually a fixed €135.
Spain
GOV.UK's Spain travel advice says children under 1.35 m must use an approved child seat secured on the back seat. They can only sit in the front if the rear seats are already taken by other children, or if the car has no rear seats. Fitting a child seat wrongly can be treated as a serious offence and fined. Car hire firms can provide child seats, so tell them you need one when you book.
The EU's Your Europe page for Spain adds that taxi passengers shorter than 135 cm don't need a seat belt on the back seat, but only on urban roads. For an airport-to-port run on a motorway, that exemption doesn't apply, so book a transfer with a seat. Our fly-cruise guide covers this in more detail.
Italy
Article 172 of Italy's highway code, published by ACI, says children under 1.50 m must be secured in an approved child seat suited to their weight. A rear-facing seat can't be used in front of an active front airbag, and in a car without seat belts, children up to 3 can't travel at all.
In taxis and chauffeur cars, children up to 1.50 m can travel without a child seat, but only if they're not in a front seat and are with at least one passenger aged 16 or over.
The same article says the driver of an Italian-registered car carrying a child under 4 in a child seat must use an anti-abandonment alarm, a device that warns you if you leave the child in the car. If you hire a car in Italy, it's likely to be Italian-registered, so ask the hire firm about this when you book the seat.
Germany
Germany's road traffic regulations (StVO §21) say children up to their 12th birthday who are under 150 cm must use a suitable approved child seat on any seat where belts are required. From age 3, a child can use the seat belt on a back seat if there's no room to fit another child seat. In cars without seat belts, children under 3 can't be carried at all.
For taxis, the duty is limited to being able to secure two children weighing 9 kg or more, at least one of them between 9 and 18 kg. A small baby may not be covered by that, so book a transfer with an infant seat or bring your own.
Ireland
Ireland's Road Safety Authority says all children under 150 cm or 36 kg must use a child seat suited to their height and weight in a car or goods vehicle, except in taxis. It's illegal to put a rear-facing seat in front of an active airbag, and children must travel rear-facing until at least 15 months old. Since 1 September 2024, only R129 seats can be sold in the EU, but you can still use an R44 seat bought before then.
The Netherlands
The Dutch government says children up to 1.35 m must travel in an approved child seat, in the front or the back, in your own car or anyone else's. A baby seat can only go in the front if the airbag is switched off. New seats should be approved to UN R129 (including i-Size), but a seat with a valid ECE R44/03 or R44/04 approval can still be used. It also warns that some countries require child seats up to 1.50 m, and that not every exception applies everywhere.
Your car seat: bring it or hire it?
Bringing your own means a seat you know how to fit and that suits your baby. Most UK airlines in our guides carry a car seat free on top of your baggage: easyJet, Ryanair and Jet2 count it in their two free baby items, and BA, TUI and Virgin Atlantic carry one free too. See car seats on planes for each airline's rules, including using it on board.
Hiring one saves carrying it, but ask for the seat when you book the car, check the approval label when you collect it, and fit it yourself using the instructions. Our car hire with a baby guide compares Europcar, Avis and SIXT seat prices. GOV.UK's driving abroad guide says it's your job to check a hire car has the equipment you need, including a suitable child seat.
Before you drive
- Check the approval label: R129, or ECE R44/03 or R44/04.
- Switch off the passenger airbag before fitting a rear-facing seat in the front, or use the back seat.
- Book transfers and taxis with a confirmed baby seat, especially in Germany and Italy.
- Take your baby out of the seat on breaks: GOV.UK's Highway Code suggests a break of at least 15 minutes every two hours, and the Lullaby Trust says car seats aren't for sleeping in once you arrive. Our road trips guide has more.
A greener way
For many European trips, the train is the lower-carbon option and needs no car seat at all. Under-4s travel free on Eurostar: see Eurostar with a baby and pushchairs on trains and ferries.
