Do You Need a Car Seat in a Taxi? UK Law Explained

You’re booking a taxi, or you’ve just stepped out of the station with a baby, and the driver has no child seat. Are you breaking the law? Is it safe? This guide explains the UK rules on whether you need a car seat in a taxi, what the legal exemption for taxis and minicabs actually says, how it applies to Uber and booster seats, and the safest way to travel by taxi with a baby or young child.

Quick Answer

No, you don’t legally need a car seat in a licensed taxi or minicab in the UK, but it’s still much safer to use one. If the driver doesn’t provide the correct child seat, children can travel without one, but only on a rear seat. Children aged 3 or over must wear an adult seat belt, and children under 3 travel without one. This exemption applies to licensed taxis and minicabs (private hire vehicles), not to ordinary cars. Taxi firms aren’t required to supply child seats, so if you want your child properly protected, bring your own or book a firm that can provide one.

What Does the Law Say About Car Seats in Taxis?

Under the main UK rule, children must normally use a child car seat until they’re 12 years old or 135 cm tall, whichever comes first. In most cases, children under 3 must always be in a child car seat. Our guide to the UK car seat regulations explains the details.

Taxis and minicabs are an exception. According to GOV.UK, if the driver of a licensed taxi or minicab doesn’t provide the correct child car seat, children can travel without one, but only if they travel on a rear seat. Specifically:

A few points that often cause confusion:

• It’s an exemption, not a safety recommendation. The law allows it, but safety organisations still say a proper child seat is far safer.
• It only applies to licensed taxis and minicabs. The exemption doesn’t cover an unlicensed lift or an ordinary private car.
• It’s about the rear seat. If no suitable seat is provided, children shouldn’t travel in the front seat.
• Taxi firms don’t have to provide seats. The charity Child Car Seats notes that taxi companies aren’t required by law to provide child car seats in taxis, private hire vehicles and minicabs. If a seat is provided, the child must use it.

Do You Need a Car Seat in an Uber?

Uber is a private hire service, so the same exemption generally applies. In practice, though, car seats aren’t common in Uber vehicles. Uber’s UK guidance says child and baby seats in vehicles on the Uber app aren’t common, and advises assuming you’ll need to bring your own if you’re travelling with a child.

A few things to know:

• Uber’s guidance says children under 15 months must use a rear-facing baby seat, and that if a passenger airbag is active, the seat must go in the back. Uber also says drivers can decline a ride if you don’t have an appropriate seat, or if they’re not comfortable installing yours.
• Children can ride only with an accompanying adult, and the adult is responsible for the child’s safety.

Because the rules and policy can differ, it’s wise to read the app’s current guidance before you book, and to plan on bringing your own seat for any baby or toddler.

Why Is a Car Seat Still Safer in a Taxi?

The legal exemption doesn’t change the physics of a crash. Child Car Seats explains that:

• Adult seat belts don’t fit small children. A lap belt can ride up over the tummy, and the diagonal strap can cross the neck, and “both of these could cause serious injury”.
• A child in an appropriate car seat is much less likely to be killed or injured than an unrestrained child or one wearing only a seat belt.
• Holding a baby on your lap isn’t safe. Which? advises against it, since you can’t hold a baby in a crash.

Which? also notes that safety experts recommend a child seat for all children under 150 cm, which goes beyond the legal minimum of 135 cm. That means the safest way to travel by taxi with a baby or child is in a car seat that suits their age, height and weight. Our guide to UK car seat laws and limits covers the full rules, and our baby car seat safety tips are a handy companion.

Travelling by Taxi With a Baby: What’s the Safest Way?

If you’re going to take a taxi with a newborn or baby, these steps give you the best protection.

1. Bring your own rear-facing baby seat. An infant carrier that meets the current standard (R129 i-Size, or R44) is the safest option. See our guide to i-Size car seats, infant carrier vs convertible car seat and the difference between R44 and R129. Babymore’s Coco i-Size baby car seat and Pecan i-Size baby car seat are infant carriers, and you can browse the full car seat range.
2. Check the seat belt can fit it. A car seat can only be used where the belt has a diagonal strap, unless the seat is designed for a lap belt or fitted with ISOFIX. Read your seat’s manual before you set off, see how to fit your ISOFIX car seat properly, and read what an ISOFIX car seat is and whether you need an ISOFIX base.
3. Ask the firm in advance. Tell the taxi company you’ll be bringing a car seat, or ask whether they can provide one. Child Car Seats warns that it may not be possible to fit a seat properly in every vehicle, because taxi seats differ in shape and size from car seats. The driver may also be uncomfortable fitting a seat, so be ready to fit it yourself.
4. Mind the airbag. A rear-facing baby seat must never be used in the front passenger seat with an active airbag, because doing so is illegal and dangerous.
5. Use the rear seat. If no suitable seat is available, children should travel on a rear seat. Our guide to which position in the car is safest for a baby’s car seat explains more.
6. Don’t use a pushchair carrycot as a car seat. A carrycot isn’t a car seat unless it has been approved as one.
7. Practise the fitting beforehand. It’s much easier to install a seat at home than on the pavement. See are baby car seats hard to install? our list of common car seat mistakes, and how tight a baby car seat harness should be.
8. Think about the journey length. Babies shouldn’t spend long periods in a car seat. Read our guide to the car seat 2-hour rule. A car seat is for travelling, not sleeping, so once you arrive, move your baby to a firm, flat cot mattress. Our cot mattress guide explains what to look for.

Dressing your baby for the journey matters too: see can you put a coat on a baby in a car seat and how to keep baby cool in the car. If you’re getting a taxi from a station or airport, a lightweight infant carrier that clicks onto a pushchair frame can make the trip easier, and our guide on taking a pushchair on a plane covers airports. See our travel systems, our pushchair guide, and read about taking a pushchair on the bus or train for other public transport options.

Booster Seats and Older Children in Taxis

For children aged 3 and over, the law allows them to use an adult seat belt on a rear seat in a licensed taxi or minicab if no suitable seat is provided. But an adult belt is designed for an adult body, so a booster seat is still safer for a child who’s below 135 cm. A booster lifts a child so the belt sits correctly across the chest and hips, and a high-back booster also gives head and side support.

• Bring a portable booster if you can. See our guide to the safest high-back booster seats.
• Don’t use the front seat. If an appropriate child seat isn’t provided, children shouldn’t travel in the front seat.
• One person per belt. Two people sharing one belt is dangerous and illegal.
• Seat belt fit matters. The belt should lie flat across the child’s chest and hips, not their neck or tummy.
• Plan for your child’s age and size. Read when a baby can face forward in a car seat in the UK, extended rear-facing car seats, and our guides to car seat stages in the UK and multi-stage car seats from birth to 12 years.
• Consider a seat that grows with your child. The Shea 360° i-Size seat is listed for 40 to 150 cm (0 to 12 years), and the Hazel i-Size seat for 76 to 150 cm (15 months to 12 years). The Kola 360° i-Size seat covers 40 to 105 cm (0 to 4 years).

What If You’re in an Emergency or an Unexpected Journey?

The law also allows exceptions for unexpected journeys. Children aged 3 or over can use an adult seat belt on a short, necessary and unexpected journey when the correct seat isn’t available. For children under 3, the only unexpected-journey exception is a licensed taxi or minicab, on a rear seat. If you can plan ahead, do. A planned journey with the right seat is always the safer choice. Our guide to taking a car seat on a plane covers another journey where planning ahead matters. If a seat has been in a crash, see when to replace your baby’s car seat after an accident, and think twice before buying a second-hand car seat.

Quick Checklist Before You Take a Taxi With a Child

• Is it a licensed taxi or minicab?
• Do you have your own car seat, or has the firm confirmed one?
• Is your seat the right one for your child’s height, weight and age?
• Can the seat be fitted with the vehicle’s belts (diagonal strap, lap belt design or ISOFIX)?
• Is the child on a rear seat, with no active airbag for rear-facing seats?
• Have you practised fitting the seat?
• Have you chosen a short, planned route with breaks for babies?

Final Thoughts

The law lets you take a licensed taxi or minicab without a car seat, but safety experts agree that a proper seat is much safer. If you can, plan ahead: bring your own seat, check the belt will fit it, and tell the firm in advance. For babies and young children, there’s no substitute for the right car seat.
