Why Safety Groups Want Toddlers to Stay Rear-Facing Longer Than the Law Requires

• The law allows a child in a height-based seat to face forward once they are over 15 months old.
• The Rear Face for Safety campaign, supported by RoSPA, the Child Accident Prevention Trust and the AA Charitable Trust, urges parents to keep children rear-facing until at least four.
• A survey by the seat specialist Axkid found 22% of children aged two to four ride rear-facing in the UK, against 83% in Sweden.

Fifteen Months Is the Legal Switch Point, and Safety Groups Say Wait Far Longer

Road safety groups urge parents to keep children rear-facing until at least four years old, or longer where the seat allows it. The legal switch point is far earlier: a child in a height-based seat can face forward once they are over 15 months old.

Four years is 48 months, so the campaign target sits 33 months beyond the legal minimum. A survey from the Swedish child car seat specialist Axkid suggests most families turn their children earlier than that. In its results, 22% of children aged two to four in the UK ride rear-facing, against 83% in Sweden, almost four times the rate.

The seat itself decides the right moment to turn a child. Its height limit and its kilogram limit count, and IAM RoadSmart, the road safety charity, says a child whose legs touch the seat in front has not automatically outgrown a rear-facing seat.

What the Law Requires Today

The GOV.UK guide states that height-based seats must be rear facing until a child is over 15 months old, after which a forward-facing seat is allowed. Only approved height-based seats can be used, and each carries a label showing a capital E in a circle and the code R129.

Older seats sold by the child’s size in kilograms carry the label ECE R44 and follow numbered groups. Group 0+ covers children from 0kg to 13kg and is rear-facing. Group 1 covers 9kg to 18kg and the guide lists it as rear or forward facing, so the 15 month rule belongs to the height-based system. Parents can choose a seat by the child’s height or by how heavy the child is.

Children must normally use a car seat until they are 12 years old or 135 centimetres tall, whichever comes first. Nothing in that guide sets an age of four for turning a child round. That gap is why the campaign groups ask families to follow safety recommendations instead of the legal minimum, and why what child car seat law requires sets only the minimum when you choose a seat.

What the Evidence and the Survey Show

IAM RoadSmart explains the case in physical terms. Young children have proportionally larger heads and developing necks. In a frontal collision, a rear-facing seat supports the head, neck and back together and spreads the forces of impact across the body.

A 2023 study in the journal Injury Prevention found that children aged zero to four who travel rear-facing had about 9% lower odds of any injury than children in forward-facing seats. The researchers also found indications of lower risks of severe or fatal injuries, though those estimates were less precise.

RoSPA gives the same direction. Its advice page states that rearward-facing seats protect a baby’s head, neck and spine better than forward-facing seats, and that many parents assume a child prefers facing forwards and turn them at the first opportunity. It also describes extended rearward-facing seats, which let a child travel rear facing typically up to around four years of age, or in some cases around six.

The Axkid figures come with limits. The company surveyed 1,000 UK and 1,000 Swedish parents and published the results in March 2025. Axkid specialises in child seats, so the findings are industry research and not an independent study. IAM RoadSmart states that the survey cannot prove different guidance alone explains the gap. Axkid says both countries follow the same UN ECE regulations, which permit forward-facing travel from 15 months, but that Sweden’s national recommendations encourage rear-facing travel until at least four.

The same survey found that 44% of parents did not know the legal minimum age of 15 months for forward-facing travel, and 11% thought the minimum age was younger than that. A further 83% said there should be clearer recommendations on how children can travel safely in cars.

What Parents Can Check Before the Next Drive

Start with the seat. Find the label (R129 for a height-based seat, ECE R44 for a kilogram-based one) and read the manual for the height and kilogram limits. RoSPA says a child needs the next stage of seat once they pass the maximum kilograms for the seat or their head rises above the top of the seat. At that point the choice is a forward-facing seat or an extended rearward-facing seat.

Check where the seat sits. GOV.UK says to deactivate any front airbags before fitting a rear-facing baby seat in a front seat, and not to fit a child seat in a side-facing seat. RoSPA says rear seats are safer than the front. A middle rear seat with a three-point belt is the safest position unless the manufacturer’s instructions name another seat. Otherwise the seat behind the front passenger is the better choice.

Check the fit. RoSPA warns that not all car seats fit all vehicles, and names a qualified car seat fitter trying a range of seats in the car as the best test before buying. To find out whether a car has ISOFIX points, look for ISOFIX labels between the base and back of the seats, or check the vehicle handbook. RoSPA also recommends replacing a seat that has been in a collision.

Parents planning a longer family trip can read how drivers keep children safer on the roads for the wider checks before setting off.

What Happens Next

The Rear Face for Safety campaign continues to press for consistent, evidence-based advice that goes beyond the legal minimum. Axkid has called for updated guidance that strongly encourages rear-facing travel until at least four, nationwide awareness campaigns, and wider access to professional car seat fitting services. The GOV.UK guide still states the 15 month rule.

For parents the next step sits with the seat in the car: the label, the manual and the limits decide when a child turns, and the safety groups ask families to use the full range and not the 15 month minimum.
