Depends on the local laws, some places they can get fined if they don't in others the law doesn't care. As far as I'm concerned it makes sense to wear a helmet whether it's the law or not. It might not save you if you get thrown under a truck, but it can offer some valuable protection for a less dramatic accident.
That's not Always true.
The laws regarding bicycle use can be different from one Place to Another.
While it is a bit silly, there are a couple of different reasons:
Personally, I Think helmets make perfect sense. Even the results from a minor injury - split eyebrow, scalp abrasions etc isn't much fun. Buying and wearing a helmet is a cheap price if all it ever does is keep me out of the ER once.

Legally it depends on if its a motorcycle or a bicycle and where you are, helmet laws aren't the same all over. In practical terms, the day to stop using a helmet is the day when you no longer think your head is worth protecting. Bottom line: you should always wear a helmet regardless of your age.

All Bicycle riders under 18 are required to wear a helmet

That depends on your age and where you're at. Helmet laws differ from place to place. Some places require all people to wear a helmet, other require people under a certain age to wear a helmet, some don't require bicyclists of any age to wear a helmet at all.
