THOUSANDS of parents are putting their children's lives at risk by not properly restraining youngsters in the back of cars, the RAC Foundation said today.

As many as one in 10 rear-seat passenger children do not use seatbelts or child restraints.

Also, two in three child safety seats are wrongly fitted, the foundation said.

The figures come during the month-long Think Before You Drive campaign, which is being promoted by, among others, the foundation.

The most recent annual figures show that 42 children under the age of 11 were killed while travelling in cars, 708 were seriously injured and 9,766 slightly injured.
