The number of children under 12 injured in car accidents dropped by more than 1,000 in the first full year since the new car seat law was introduced.
The Royal Society for the Prevention of Accidents (RoSPA) said the figures are proof that the law is helping to reduce pain and suffering for children and their families.
New legislation introduced in September 2006 made it compulsory for children under 12 and below 4ft 5in (1.35m) tall to use child car seats or booster seats.
In 2005, the year before the legislation was brought in, 7,033 children under 12 were injured while passengers in cars, and 326 of them were killed or suffered a serious injury. Last year the number hurt was cut to 5,927, with 271 killed or seriously injured.
Kevin Clinton, RoSPA Head of Road Safety, said: "This is more good news following the announcement in the summer that road deaths in Britain were down to 2,946 - the first time they have fallen below 3,000 since records began 80 years ago.
