The new rules come into force on March 1st 2017 and will limit the use of backless booster seats for older children. Under the new rules, backless booster seats - also known as booster cushions - will only be allowed for children taller than 125cm and weighing more than 22kg (3st 6.5lbs). Currently, children weighing as little as 15kg (2st 4lbs) - around three years old - can travel in backless booster seats. Quite simply, the rules have changed to discourage use of this type of seat, as these boosters offer much less protection in a crash.
However this change only applies to new backless booster seats entering the market after March 1st 2017 - if you already own one, it’s fine to continue using it.
There are a few exceptions to the law where children can legally travel without a car seat:
When choosing a seat, make sure you pick one that will be secure: look for one either with a diagonal strap, one that is designed to be used with a lap seat belt, or one that has ISOFIX anchor points (which keep the chair attached to the seat of the car).
The driver always bears responsibility for children being in car seats when travelling.
