What the helmet law requires in California
Who the rule covers, the exemption test if there is one, and any related gear the law still requires.
| What the law requires | What it means |
|---|---|
| Helmet required for everyone | Under Vehicle Code Section 27803, a driver and any passenger must wear a safety helmet when riding on a motorcycle, motor-driven cycle, or motorized bicycle. The rule covers all ages, so there is no point at which a rider ages out of it. |
| Must meet the federal safety standard | The helmet has to meet the standard set under Vehicle Code Section 27802, which ties to US DOT Federal Motor Vehicle Safety Standard 218. It must be fastened with the straps and fit the head securely without excessive movement. |
| Operating or riding without one is unlawful | It is unlawful to operate a motorcycle, or to ride as a passenger, if the driver or any passenger is not wearing a compliant helmet. Both the operator and a bare-headed passenger are covered by the offense. |
| Who is exempt | What it means |
|---|---|
| Fully enclosed three-wheeled vehicle | Section 27803 does not apply to a person operating or riding in a fully enclosed three-wheeled motor vehicle that is at least seven feet long, four feet wide, and 900 pounds or more unladen, if it meets the federal safety standards. |
| No age or experience exemption | Unlike states that let riders 21 and older go without a helmet, California grants no exemption based on age, license tenure, insurance, or a safety course. A novelty helmet that does not meet the federal standard also does not satisfy the law. |
What you can do right now
Concrete, neutral steps to ride within the helmet law in California. This is legal information, not legal advice.
- Buy a US DOT-compliant helmet
Look for the DOT certification label and check that the helmet meets Federal Motor Vehicle Safety Standard 218. A novelty or costume helmet does not satisfy Section 27803.
- Fasten and fit it every ride
The law requires the helmet to be fastened with the straps and to fit securely without excessive movement. A helmet worn unbuckled or loose does not meet the standard.
- Make sure your passenger is covered
A bare-headed passenger is a violation even if you are wearing a helmet. Carry a second compliant helmet or do not ride two-up.
- Do not expect an age exemption
California has no rule that lets riders 21 or older skip the helmet with insurance or a safety course. Plan to wear one on every ride, regardless of your age or experience.
If you were cited over a helmet, a local traffic attorney or public defender can explain how the charge is handled and whether an exemption applies to you.

What riders in California get wrong about helmets
California is an all-rider helmet state, and the statute leaves no room to argue. Vehicle Code Section 27803 says a driver and any passenger must wear a safety helmet when riding on a motorcycle, motor-driven cycle, or motorized bicycle. It applies to every age, so a rider never ages out of it, and it reaches the passenger as much as the operator. The helmet cannot be any helmet. It has to meet the standard set under Section 27802, which points to US DOT Federal Motor Vehicle Safety Standard 218, and it must be strapped on and fit securely without excessive movement. A novelty helmet that fails the federal standard does not count. The one narrow carve-out is for a fully enclosed three-wheeled vehicle of a set size and weight. California grants no exemption for age, experience, insurance, or a completed safety course, which sets it apart from states like Florida and Texas.
