California Motorcycle Helmet Law

In California, anyone who drives or rides on a motorcycle must wear a safety helmet that meets U.S. Department of Transportation and state safety standards. It must be fastened with the helmet straps and fit securely without excessive lateral or vertical movement.
The exception to this rule is when a person is operating or riding as a passenger in a fully-enclosed three-wheeled motor vehicle that is seven feet long or more and four feet wide or more, and has an unladen weight of 900 pounds or more.
Because these regulations can change, it’s best to check with the Commissioner of Motor Vehicles or related department before riding a motorcycle on California roadways.
