Businesses are being warned to keep drivers up-to-date with the new changes regarding the law governing child car seats.
From today, child seats are compulsory for children under 12 years old or under 135cm (4ft 5in) tall.
Drivers who ignore the new regulations face a £30 on-the-spot fine or up to £500 if the case reaches court.
The regulations have been introduced to address the issue of car manufacturers developing safety restraint systems for passengers over 150cm tall with adult bone structure.
A child involved in an accident without a child seat or booster faces an increased likelihood of injury. The Government expects the new regulations to prevent up to 2000 child injuries every year.
