Under California Vehicular Code 27803, it is unlawful to operate or ride as a passenger on a motorcycle, motorized cycle or motorized bicycle without a helmet. Depending on the jurisdiction, penalties may range from a $10 fine and proof of correction to a $250 fine and one-year probation. Helmet laws in California are intended to provide everyone with additional safety benefits when using these motorized vehicles. Head trauma accounts for most of the severe and fatal injuries suffered by motorcyclists.

Riding helmets in California

According to the California Department of Transportation, most crashes occur on trips shorter than 5 miles while traveling less than 30 miles per hour. Wearing a motorcycle helmet reduces the risk and potential severity of suffering a head injury. State law requires the head to be securely fastened in by helmet straps that minimize vertical and lateral movement. The helmet must show certification from the manufacturer that it was built in compliance with U.S. DOT Federal Motor Vehicle Safety Standard 218.
