Could you be facing a car seat fine?

76% of parents unaware of current car seats laws

Parents could be leaving themselves open to large fines for not knowing the current child car seats laws, a recent Which? survey has discovered.

Current UK law states that children must use a child car seat until they are 12 years old, or 135cm tall, whichever comes first – but when we surveyed more than 1400 parents, only 7% were able to identify the age and height correctly. 

Car seat laws

The fine for not using the correct child car seat, if caught, is a fixed-rate penalty of £100, up to £500 if the matter goes to court.

Our survey also revealed that one in five (18%) of parents fail to use any car seat for their children ages six to 10 years old and, shockingly, 1% of parents with a one to five year are not using a car seat in their car – both of which are illegal – and unsafe.

When do I turn my baby forward-facing? 

A quarter of parents are also potentially exposing their babies to a higher risk of serious injury, by falsely believing that they should swap their car seat when their child turns one. 26% of parents we surveyed didn’t know when to change car seats.

Our advice is to keep your baby in their rearward-facing car seat for as long as possible – until they reach the weight limit (usually 13kg for a Group 0+ car seat), or they get too tall for the seat and the crown of their head comes above the protective shell. 

Not only is keeping your child rearward-facing safer, it also means you can delay spending money on a new seat until they’ve fully grown out of the first seat.
