Its not 12 in the UK. It's up to 1.35m OR 12 years old.
Up to 1.35m (or under 12) you must use "an appropriate child restraint (booster seat or cushion) for the child's weight"
So in other words, if you have a child of any age who is over 1.35m tall you use a normal seat belt just like an adult.
If you have a 9 year old who is under 1.35m, but who is, shall we say, well-fed - they can use a booster seat/cushion that is fitted per manufacturers instruction and keeps the seat belt correctly position per height.
If you have a car full of 9 year old boys who are all under 1.35m tall in a UK car they need to be on boosters and using the adult seat belts.
Out here in the Good Old UA of E, there are no rules for any sort of seat belts for adults or kids (or if they are, then none are enforced). We see toe curling sights every day of cars doing 120kmh down the motorway with toddlers hanging out of car windows waving or even kids with their heads and shoulders out of sun roofs waving their hands. Genuine wisdom here is that your toddler is safer on your wife's lap in the front passenger seat (no seat belt) than anywhere else.....
A lot like the UK in the 70s actually!
