Anyone who has read todays Daily Express will see an article about grand parents not being aware of seat belt laws. It states that the driver is responsible for children up to 12 years old. To clear things up I have just copied Rule 100 from the Highway Code this morning.

The Highway Code.
Rule 100

The driver MUST ensure that all children under 14 years of age in cars, vans and other goods vehicles wear seat belts or sit in an approved child restraint where required (see table above). If a child is under 1.35 metres (approx 4 feet 5 inches) tall, a baby seat, child seat, booster seat or booster cushion MUST be used suitable for the child’s weight and fitted to the manufacturer’s instructions.
