US Helmet Laws
Helmet laws fall into four general categories: required for everyone, required for everyone under 21, required for everyone under 18, and not required at all. Many states have their own special stipulations for passengers, engines under 50cc, or the amount of health insurance a rider must carry to go without a helmet.
