Car Seat Laws

Car Seat Laws

In the UK, car seat law dictates that all children must use an approved car seat until they are 135cm in height or, until they are 12 years of age. In some European countries, like the Republic of Ireland , the maximum height limit is 150cm. Before travelling, make sure that your car seat complies with car seat legislation to ensure your child’s safety whilst in the car.

Depending on the height and weight of your child, there are a number of  approved car seats to choose from including:

  • Group 0+ - rear facing infant car seat with integral harness – from birth to 13kg
  • Group 1 – forward and rearward-facing car seats with integral harness– from 9 to 18kg
  • Group 2/3 – Booster seats – from 15 to 36kg

Buckle up - It’s The Car Seat Law

Approved car seats carry an orange i-Size (UN R129) label, which means they have been tested to the most recent and stringent European safety standard and UK car seat laws. A relatively new legislation, not all car seats will carry this certification. The Maxi-Cosi 2waypearl is designed to meet the latest i-Size regulations for in car travel.

Most car seats will carry and orange ECE-R 44/04 label which ensures a minimum level of safety, or an ECE-R 44/03 label which means that an approval according to an older standard. All car 

seats featuring the ECE certification meet UK and EU car seat laws.

i-Size (UN R129) car seat legislation

i-Size or UN R129 is the that latest car seat safety regulation, offering the most stringent safety performance. Tested to increase the safety level for children whilst travelling in cars, the new

i-Size legislation makes rearward facing travelling mandatory for babies up to 15 months old. This standard ensures a better protection of baby’s head and neck, offering optimal safety. Unlike existing car seat laws, i-Size uses length classification, instead of weight, to help when choosing the right car seat. To reduce the chances of incorrect installation i-Size demands the use of ISOFIX.

European Approved ECE R44/04 Car Seat  legislation

Every child car seat produced in Europe will have an orange ECE R44 approval label. It is this label which guarantees that the car seat complies with the basic safety requirements, as set out in the European safety standard ECE R44/04 or /03.

Making sure your child’s car seat has this label, is a good starting point when looking for a new car seat. Ease of use and the protection offer can vary significantly between orange labelled ECE R44 seats, so make sure to try before you buy. It may be useful to consult the latest European safety test, which is conducted on a yearly basis, to help parents come to the best choice of seat for you and your child.
