Motorcycle helmets

A motorcycle helmet is a type of protective headgear used by motorcycle riders. The primary goal of a motorcycle helmet is to protect the rider's head during impact, although many helmets provide additional conveniences, such as face shields, ear protection, intercom etc.

Motorcycle helmets are generally believed to greatly reduce injuries and fatalities in motorcycle accidents, thus many countries have laws requiring acceptable helmets to be worn by motorcycle riders. These laws vary considerably, often exempting mopeds and other small-displacement bikes. As with seat belt legislation the actual effects of imposing helmet wearing are a matter of dispute with evidence available indicating a risk compensation effect.
