Child safety in cars: A wide gulf has developed between technology and legislation
Children up to four years of age would be better protected in cars if they traveled rearward-facing in a suitable child restraint, rather than forward-facing as is the usual practice in most of Europe. Suitable seats are widely used in the Nordic countries, but are not readily available in the rest of Europe. The law and the supply of seats, together with the information for parents, are in urgent need of revision. These are the conclusions of a study commissioned by ANEC looking at the lessons to be learned from accidents in the UK, US and
Sweden
A small quote from section: 5 - Findings based on the UK fatal Accidents Data
5.1 Forward Facing child seats
....In six of the eight accidents the research team judged that the child would have survived had they been seated in a suitable rearward facing car seat. The agees of these children ranged from five and three-quarter months to just under four years old. In the remaining two cases the protection offered by a rearward facing seat would have been compromised by additional loading from luggage in the boot area and gross roof intrusion into the seating position. The children in these accidents were aged seven months and one and a half years old.
The organization wants to make rear-facing car seats available in all of Europe and says that children should stay rear-facing up till four years.
