Seven out of ten child car seats are still failing our safety checks. All new child car seats must have the ECE R44.04 mark on them. Any new seat without this mark is not legally acceptable in the UK and may not be safe.
Older seats with R44.03 can still legally be used, but seats of this age could have degraded and may not be as safe. You should never use a second hand seat unless you know its full history, as it may have been dropped or in a crash and have damage you can't see.
Contact the road safety and active travel team on 023 9268 8262 for advice and resources on fitting a child car seat.
