Do you need a child seat in a Madrid taxi?

Short answer, and it surprises most visitors: inside Madrid, no. A taxi may carry a child under 135 cm without a child seat, provided the child travels in a rear seat.

This is not a loophole or a tolerated habit. It is a written exception — article 119 of Spain’s General Traffic Regulations — that applies to taxis in urban traffic.

But there is a detail almost nobody mentions, and it is the one that matters.

The exception applies in the city, not outside it

The exemption exists for the urban taxi: the short hop, the one hailed in the street, the trip across town. The moment the journey leaves the city, it no longer applies and the general rule returns: under 135 cm means an approved restraint matched to the child’s height and weight.

In terms of real journeys:

	Does the law require a seat?
Airport to your hotel in Madrid	No
Across the city	No
A day trip to Toledo or Segovia	Yes
A transfer to Salamanca or Valencia	Yes

If you are taking children on a day trip, the seat is not optional, taxi or not.

And we fit one anyway

That the law permits something does not make it the best idea. A small child in a rear seat with only an adult belt is held by a harness designed for a body that is not theirs.

So we keep seats and fit them even when the trip is urban and nothing obliges us to. Always ask, even if you think you do not need one.

What we have:

• Group 0/1 — for the smallest, from newborn.
• Group 2/3 — for those who have outgrown the baby seat.
• Booster — for older children not yet at 135 cm.

If you are not sure which applies, tell us the child’s age and rough weight and we will work it out.

The one thing to remember

Child seats need 24 hours’ notice.

It is the only thing in this article that can spoil your trip, so it is in bold.

The reason is simple: the seats do not live in the car. They take up most of the boot and the great majority of journeys do not need them, so the right one has to be collected, fitted in the specific vehicle picking you up, and checked that it anchors properly. That is not something to improvise between two jobs.

Everything else we do takes three hours’ notice. A seat needs a day. If you message us three hours before a flight asking for one, the honest answer will be that we cannot make it.

What to tell us when booking

This is enough:

• How many children, and the age of each.
• Rough weight, if you know it.
• Whether the journey leaves Madrid.

With those three things we pick the seat, fit it before setting off, and you do not have to drag your own through the airport.

A note if you are flying in

If you travel with your own seat, most airlines take it as checked baggage at no charge. It is also one of the items most often damaged in the hold, and fitting an unfamiliar seat on the kerb outside arrivals with a tired child is not a good start to a holiday.

Having ours already fitted tends to work out better.
