A new law has come into force in the UK to further regulate the use of child car seats. All children under the age of 12 will have to use some form of child car seat, unless they are taller than 135cm (4ft 5in).
(Failure to comply could lead to a £30 on-the-spot fine for drivers, or £500 for a court conviction. There are a lot of very annoyed children who think it's childish to sit on a booster seat.))
