Car Seats in Ubers, Taxis and Private Cars: What the Rules Say and How to Get the Right Seat

Do you need a car seat in an Uber or taxi?

The rules vary because three different kinds of vehicle get called "a car". A taxi you hail in the street, a car you summon with an app and a chauffeured vehicle booked in advance are regulated differently in many places, and they also behave differently in practice: only one of the three can reliably promise a seat in advance.

This guide gives the official wording I could confirm, says plainly where I could not open the relevant page, and then moves to the practical question: how to get the right seat into the right car, including on a flight.

It is not legal advice. Child seat laws are set by cities, states and provinces, they change, and the penalty for getting it wrong is not a fine but a child who is not properly restrained.

What New York City's taxi regulator says

The New York City Taxi and Limousine Commission's passenger FAQ answers the question directly. Under the heading on child safety seats in taxicabs, it states that New York State law requires that all children under the age of 4 ride in child safety seats, and that children must ride in a child restraint system until age 8. In the yellow taxi section it repeats that children under 4 must ride in child safety seats and children under 8 must ride in a child restraint system.

Two other points from the TLC passenger FAQ:

• Acceptable restraints. A safety seat, harness, vest or booster seat secured with the vehicle's belt system. The seat belt alone is not sufficient.
• For-hire vehicles. Passengers in a TLC-licensed vehicle are allowed to bring and use their own car seats and booster seats. Some car services provide seats on request, and the TLC publishes a provider list.

The page does not say whether taxis are exempt from these requirements, and it does not give age or weight rules for for-hire vehicles beyond what is quoted. For a New York trip with a child, read that page before you arrive; the JFK to Manhattan transfer page shows what a pre-booked airport run involves.

What the UK rules say

The UK government's child car seat rules are clear for private cars. Children must normally use a child car seat until they are 12 years old or 135 centimetres tall, whichever comes first. Over 12, or taller than 135 cm, a seat belt is used instead.

Height-based seats must be rear-facing until the child is over 15 months, and only approved seats can be used in the UK, marked with an "E" in a circle and either "R129" or "ECE R44" for weight-based types.

The pages I opened do not mention taxis or private hire, and the government's page on seat belts says there are "only a few exceptions" to wearing one, pointing to a separate page I could not read. So I cannot tell you what the exception, if any, is for a taxi or minicab. The practical rule is to ask the operator before the ride, not on the kerb. Heathrow arrivals are a common test of this, and the Heathrow to central London page covers that road.

What Canada and Ontario say

Transport Canada's child car seat page covers choosing and installing a seat, recall notices and safety testing. It links to the federal safety regulations for seats and booster seats. It does not discuss taxis or exemptions.

Provinces set the rules on who must use a seat, in which stage and in which vehicles. I could not open the Ontario government's text on taxi and limousine exemptions when I checked in October 2026, and I will not guess at it. For a trip in Ontario, read the province's current child seat guidance and ask the operator whether a seat is supplied.

What the health agencies recommend, whatever the law says

Where a law is silent or has an exemption, the medical guidance still applies. Two US sources, in plain language:

• The Centers for Disease Control and Prevention says to keep children rear-facing as long as possible; to use a forward-facing seat with a harness and top tether until the child reaches the seat's limits (at least age 5); to use a booster until the seat belt fits, usually around ages 9 to 12; and to keep children buckled in the back seat until age 13. See the CDC's child passenger safety page.
• The American Academy of Pediatrics, on its HealthyChildren.org car seat guidance, says all infants should ride rear-facing starting with the first ride home, and that children should stay in a booster seat until adult seat belts fit correctly, typically around 4 feet 9 inches and ages 8 to 12. It advises confirming that a seat fits the vehicle and that the driver knows how to install and use it.

If you are choosing between a vehicle with a seat and one without, the guidance points one way.

Who supplies the seat? Four ways to travel compared

The guide to airport transfer versus taxi versus rideshare compares the three more broadly. The table here is about practicality, not the law. Whether a hailed taxi is legally required to carry a seat for your child depends on the city, and the sources above show that NYC's regulator states the requirement.

Should you bring your own seat?

For short trips and for families who travel often, yes. You know the seat, you know how to fit it, and its safety is not in question. The AAP's guidance echoes that: confirm the seat fits the vehicle and the person driving knows how to use it.

The downsides are bulk and time. A convertible seat is heavy, and installing it on a kerb in the rain is no one's idea of a good start to a trip. On arrival at an airport, the combination of luggage, children and a seat is where a pre-arranged vehicle with a seat already fitted earns its place.

Flying with a car seat

The AAP and the FAA recommend securing children under 40 pounds in a certified child restraint on a plane. Rear-facing, convertible and forward-facing seats generally work; booster seats and travel vests do not. Look for the label that reads "This restraint is certified for use in motor vehicles and aircraft." Larger children may use the airplane seat belt.

Practical consequence: if you plan to use a seat on the flight, you will probably also want it in the car at the other end, and the ground transport must be told in advance. If you plan to check the seat instead, arrange a seat at the destination.

How to request a seat on a pre-booked transfer

Do it at the booking stage, not at the kerb.

1. State the child's age, weight and height. The right seat is a function of all three.
2. Say which type you need: rear-facing, forward-facing or booster. A rear-facing infant seat is a different product from a booster.
3. Mention whether you are bringing your own so the driver knows whether to expect it.
4. Confirm the seat is on the confirmation. If it is not written there, it is not reserved.
5. Allow time at pickup for fitting, especially if the seat is yours.

Onroutz.ca offers child, toddler and booster seats on request at booking, and the guide to how private airport transfers work explains the rest of the process. The private transfer service explains how a transfer is arranged, the airport limo page covers airport runs around Toronto, and the Pearson to downtown Toronto transfer is a common family route.

Book this transfer

Five questions to ask any driver or service before the ride

A short message before pickup avoids most disputes at the kerb. Ask the following, in writing if you can:

1. Is a seat of the right type supplied, or must I bring one?
2. Is it rear-facing, forward-facing or a booster, and for which weight range?
3. Who fits it, and will the driver check that the harness or belt is correct?
4. Is the seat on the booking confirmation, and is it the same for the return trip?
5. If the seat is not available on the day, what happens, and will the ride still go ahead?

A service that answers these clearly has done this before. A service that cannot answer the first question has told you what you needed to know.

Mistakes parents make with car seats and rides

• Assuming a hailed taxi has a seat. It almost never does.
• Using only the seat belt for a small child. The NYC regulator says the belt alone is not sufficient for the ages it covers.
• Putting a rear-facing seat in the front. The CDC says rear-facing seats should never go in the front seat.
• Bringing a booster as the flight seat. Boosters and travel vests are not suitable on planes, according to the AAP.
• Forgetting the return. A seat arranged for the arrival must also be ordered for the departure.
• Not telling the driver. A seat only helps if the driver knows it is coming.
