Most drivers are keenly aware of the legal need to keep their car insurance and road tax up to date, but a large proportion are not so knowledgeable about the rules governing child car seats, research has revealed.
To mark Child Safety Week the AA has launched a campaign to raise parents' awareness of the importance of having the right car seat for a child`s age and height - and to make sure it is fitted securely.
Manchester United boss Sir Alex Ferguson, whose 10-year-old grandson Charlie was badly hurt in a car crash last month, is lending his support to the safety campaign.
"I urge all parents and children to pay attention to using and fixing their seatbelts properly, over the shoulder as it should be," he said. "This can save your life."
The AA said that with two thirds of child seats in the UK not fitted securely, the summer holiday "could be an accident waiting to happen".
AA president Edmund King said: "The AA/Populus poll of 16,500 respondents showed that 83% are not aware of legislation requiring children to use the appropriate restraint or child seat.
"Modern seatbelts are not uncomfortable, so parents or drivers need to ensure that children are appropriately belted up. It can be a matter of life or death."
