Child Seats in Taxis: The German Exemption and Its Limits

Half past one in the morning, the flight ran ninety minutes late, the child is asleep on your shoulder, and the car at the front of the rank has no child seat in it. Almost every parent meets this scene once, and it almost always ends the same way: you get in.

There are now five pieces on this site about airport transfers that mention child seats in a subordinate clause — state the requirement when you book. True, and not enough. The question underneath is a different one: why is a taxi allowed to carry your child without a seat when your own car would not be? The answer sits in one rather convoluted sentence of the German road traffic regulations, and it is considerably tighter than the pub version of it.

What § 21 StVO requires in the ordinary case

The general rule is § 21 paragraph 1a sentence 1 of the Straßenverkehrs-Ordnung, and word for word it reads:

„Kinder bis zum vollendeten 12. Lebensjahr, die kleiner als 150 cm sind, dürfen in Kraftfahrzeugen auf Sitzen, für die Sicherheitsgurte vorgeschrieben sind, nur mitgenommen werden, wenn Rückhalteeinrichtungen für Kinder benutzt werden, die den [in Richtlinie 91/671/EWG] genannten Anforderungen genügen und für das Kind geeignet sind.“

In English: children up to their twelfth birthday who are shorter than 150 cm may be carried in a motor vehicle, on seats for which belts are prescribed, only if child restraints are used that meet the requirements of the EU directive and are suitable for the child.

Two things about it are routinely misremembered. First, the two conditions are cumulative — under twelve and under 150 centimetres. A ten-year-old of 152 cm needs no seat; neither does a thirteen-year-old of 140 cm. Second, the duty falls on whoever is driving, not on the parent in the back.

What a breach costs is set out in the official fines catalogue, the annex to § 1(1) BKatV. Item 98 covers carrying a child without arranging the prescribed restraint — wrongly secured — at 30 euros for one child and 35 for several. Item 99, carrying a child with no restraint at all, runs to 60 euros and 70. The ADAC adds in its legal pages that a penalty point in Flensburg comes with the 60-euro band; that is the motoring club’s reading, not wording from the catalogue itself.

Taking a child in a taxi without a seat: what the exemption actually says

Here is the sentence everything turns on. § 21 paragraph 1a sentence 2 number 3 StVO, departing from sentence 1:

„ist a) beim Verkehr mit Taxen und b) bei sonstigen Verkehren mit Personenkraftwagen, wenn eine Beförderungspflicht im Sinne des § 22 des Personenbeförderungsgesetzes besteht, auf Rücksitzen die Verpflichtung zur Sicherung von Kindern mit amtlich genehmigten und geeigneten Rückhalteeinrichtungen auf zwei Kinder mit einem Gewicht ab 9 kg beschränkt, wobei wenigstens für ein Kind mit einem Gewicht zwischen 9 und 18 kg eine Sicherung möglich sein muss; diese Ausnahmeregelung gilt nicht, wenn eine regelmäßige Beförderung von Kindern gegeben ist.“

Rendered: in taxi traffic, and in other car-based services where a duty to carry under § 22 of the Passenger Transport Act exists, on rear seats the obligation to secure children with officially approved and suitable restraints is limited to two children weighing 9 kg or more, with a restraint having to be possible for at least one child in the 9-to-18-kg band; and the exemption does not apply where children are carried regularly.

Read it twice, because four separate limits are packed into that, and the popular summary — taxis do not need child seats — contains none of them.

First: rear seats only. The front passenger seat does not appear in the exemption at all.

Second: two children from nine kilos. The provision limits an existing duty; it does not mandate equipment. The ADAC translates that for practical purposes as a taxi having to carry seats for two children from nine kilos, at least one of them in the 9-to-18-kg class. That reading sits comfortably with the wording, but it is the club’s reading rather than the text’s.

Third: not for regular carriage of children. If your child rides to school by taxi every morning, the exemption drops away. It is aimed at school runs and standing contracts.

Fourth — and I am not going to soften this one: an exemption from a legal duty is not a statement that the thing is equally safe. The legislator decided a taxi cannot realistically be equipped for every child size and still function as a taxi. Physics was not consulted. Holding both of those in your head at once is uncomfortable, and more honest than picking whichever half suits you.

A child in the front of a taxi: exactly where the exemption stops

Because the exemption speaks only of rear seats, sentence 1 applies unchanged in the front. A child under twelve and under 150 cm belongs in a suitable restraint on the front passenger seat, taxi or not. That is not a question of interpretation, just the scope of the provision.

A second rule sits alongside it, not in the StVO but in the construction regulations. § 35a(8) sentence 1 StVZO: „Auf Beifahrerplätzen, vor denen ein betriebsbereiter Airbag eingebaut ist, dürfen nach hinten gerichtete Rückhalteeinrichtungen für Kinder nicht angebracht sein.“ Rear-facing child restraints may not be fitted to a front passenger seat with a live airbag in front of it. So an infant carrier does not belong in front of an armed airbag, and vanishingly few taxi drivers will deactivate theirs for you. The fines catalogue lists that breach at item 203.1 for 25 euros.

And § 35a(13) StVZO provides that restraints for children up to fifteen months of age may only be fitted facing rearwards or sideways. Which in practice means: until fifteen months your child travels backwards, and backwards means in the back.

Infant carriers: the gap below nine kilos

This is where it gets concrete for parents of babies. The exemption limits the duty to two children weighing 9 kg or more. A baby below that weight does not appear in the limitation — and therefore not in what the taxi has to have aboard either. The ADAC puts it flatly in its press notice on securing children in taxis: „Der Taxifahrer muss nur Sitze für Kinder ab 9 Kilo Körpergewicht, aber keine Babyschalen bereitstellen.“ The driver need only provide seats for children from nine kilos, not infant carriers. In the same piece the club notes that where a child is injured in a crash, shared liability between driver and parents comes into consideration.

Boiled down to something you can carry around: below nine kilos, you bring the carrier yourself or you book a vehicle that has one. Everything else is hope.

One edge case worth knowing, which surfaces with older vehicles: under § 21(1b) StVO, children under three may not be carried at all in vehicles that have no seatbelts fitted.

What actually happens at the rank

The law is one thing, the car in front of you another. Some taxis have an integrated fold-out booster built into the rear bench — common in the classic estate cars, and precisely the design that satisfies the 9-to-18-kg requirement. Some have a loose seat in the boot that then eats half the luggage space. Many have nothing.

A taxi cannot simply turn you away inside its mandatory service area: under § 22 PBefG the operator is obliged to carry you provided the conditions of carriage are met, the journey is possible with the vehicles normally in service, and nothing unavoidable prevents it. § 47(4) PBefG confines that duty to the mandatory service area. How this duty to carry interlocks with the municipally fixed tariff — and why app services do not have it — is set out at length under taxi fares in Germany.

The most reliable route is the dullest: book ahead and say what you need on the call, rather than hoping at the rank. In Berlin, Taxibambino has built an entire service around exactly that, listing three seat classes by weight — infant carrier to 13 kg, seat for 9 to 18 kg, high-back booster for 15 to 36 kg — with a driver meeting you inside arrivals at BER and a fixed price, by its own account around 40 to 55 euros into the centre (as of 2026). That such a fixed price can sit above the metered fare is part of the calculation.

Child seats with Uber, Bolt and FREENOW

Here the law gets genuinely interesting, and the common assumption that app rides are basically taxis leads you astray.

The § 21 exemption bites for taxis (limb a) and for other car services only where a duty to carry under § 22 PBefG exists (limb b). For private hire — the category the well-known app services operate in within Germany — § 49(4), final sentence PBefG says without ambiguity: „Die §§ 21 und 22 sind nicht anzuwenden.“ Sections 21 and 22 do not apply. No duty to carry, so no limb b. And private hire is expressly not taxi traffic under § 47, so no limb a either.

The result: on a private hire journey the full child seat duty of sentence 1 applies. Order an actual taxi through an app — FREENOW dispatches both taxis and private hire in Germany — and you are back inside the exemption. It turns on the vehicle category you pick during booking, not on the logo of the app, and no price comparison makes that visible.

What the operators themselves say is remarkably thin. Uber’s own help page for Uber Car Seat lists Los Angeles, San Francisco, Orlando, Miami, Atlanta, Washington DC and New York City, with one Nuna-branded seat per trip and a ten-dollar surcharge. No German city appears. Bolt’s rider help says a dedicated category exists “in some cities” and otherwise advises contacting the driver after the request, and if there is no seat, “please provide your own child seat” — adding explicitly that the driver may cancel the request if none is available.

Bringing your own seat

The solution that always works, with three practical snags.

The driver does not have to fit it. I know of no provision obliging a driver to install a seat you have brought; the duty says the child must be secured, not who does the fastening. Assume you will be doing it yourself, in the dark, on an unfamiliar car, with a tired child beside you.

ISOFIX is not a safe assumption. Many seats can be belted in with the three-point belt instead; if yours cannot, it may be useless in somebody else’s vehicle.

And the seat has to get there. Whether your airline carries a car seat in addition to the free allowance, counts it against that allowance, or wants it registered in advance is a commercial rule rather than a legal one, and it varies by carrier. The mechanics behind it — how airlines price bulky and special baggage, and what notice periods they attach — are broken down under excess and special baggage charges; the specific line for child seats you will have to look up with your own airline.

A booked transfer is a different product from a taxi

The decisive difference is not the price but the commitment. Flag a taxi and you get whatever turns up; book a transfer and the seat is a line item you can hold the operator to. It never happens by itself: not one of the large agents adds a seat unprompted, several charge for it, and on minibuses and shared shuttles it is frequently not possible at all by design. What five operators’ terms say about that — including the driver’s right to refuse the journey if no seat was booked — I worked through under booking an airport transfer.

Before deciding, one sober figure helps: the distance and drive time from airport to hotel. Twelve minutes without a seat is a different judgement call from two hours of trunk road, and how long the run really takes takes thirty seconds to check.

From your home airport there is also the option that dissolves the problem entirely — your own car with the seat already correctly fitted, plus a parking space. What an airport parking space costs by length of stay is sorted by location there, and with a toddler it lands below two transfers surprisingly often. If you would rather work with the meter in Frankfurt, current figures live under what a Frankfurt taxi ride costs.

German law does not travel with you

Taking the German exemption abroad in your hand luggage is the most expensive mistake in this piece. Three destinations that already feature on this site, three very different states of evidence.

Spain. Article 117 of the Reglamento General de Circulación requires child restraints for minors „de estatura igual o inferior a 135 centímetros“ — up to and including 135 cm, a different threshold from the German 150. The taxi exemption lives in article 119(2) and is the Spanish twin of the German one: „Cuando los taxis circulen en tráfico urbano o áreas urbanas de grandes ciudades podrán transportar a personas cuya estatura no alcance los 135 centímetros sin utilizar un dispositivo de retención homologado […], siempre que ocupen un asiento trasero.“ Urban traffic only, rear seat only. On the road out to Alcúdia it does not apply. Worth noting: Real Decreto 518/2026 of 24 June rewrites that paragraph with effect from 1 October 2026 — and re-enacts the taxi sentence word for word. The exemption stays. How the island otherwise divides between bus, taxi and transfer is under Mallorca airport transfer.

Turkey. The Karayolları Trafik Yönetmeliği deals with it in Madde 150, and on taxis it is notably stricter than either Spain or Germany: „Çocukların taksilerde seyahatleri sırasında, çocuk bağlama sistemleri kullanmaları, yok ise arka koltukta oturmaları zorunludur.“ Children travelling in taxis must use child restraint systems; where none is available, they must sit in the rear. The general threshold there is 150 cm and 36 kg, with children over 135 cm permitted to use the ordinary belt provided they are not in the front. For the 135 kilometres from Antalya to Alanya that is a solid argument for a transfer with a confirmed seat over the taxi outside the terminal — the route logic is under Antalya airport transfer.

Egypt. Here I will be straight with you: I could not find an official source I would be willing to quote. The figures in circulation about Traffic Law No. 66/1973 and its implementing regulation contradict each other — under four, under seven, under ten, under 135 cm — and none of them leads back to a text you can check. So I am not going to assert anything about it. Practically, Hurghada and Marsa Alam get the same treatment as any destination with an unclear legal position: if you need a seat, book it in writing with the transfer operator instead of negotiating for it at the airport.

Every other destination follows the same pattern: the rules differ on the height threshold, on whether a taxi exemption exists at all, and on whether it survives outside the city. Look them up before you travel — not in a travel blog, but at the transport ministry or the country’s motoring club.

Back to half past one in the morning. What I have settled into is not legal advice but an order of operations. At the home airport, the family car goes, with the seat already in it. At the destination, the seat is booked in writing with the transfer before the flight is booked. And for the one journey that cannot be planned, the exemption exists and it will get you home — it simply does not replace the two decisions before it. All legal positions here reflect September 2026; regulations and penalty rates get adjusted, the structure of the rule rather less often. More on fares under Taxi & Fares.
