A Helmet Question Shouldn't Decide Your Injury Claim
Helmets work. They sharply reduce the chance of a life-threatening or fatal brain injury, which is exactly why California requires them. But after a crash, the helmet becomes something else: one of the first things an adjuster asks about, and one of the easiest ways to argue your compensation should be lower.
You may still have a strong claim if:
A driver caused the crash, whether or not you were wearing a helmet
Your helmet cracked, came loose, or failed to protect you
The insurer says your helmet wasn't certified or wasn't fastened properly
You were a passenger on the motorcycle
The helmet rules exist to keep riders safe, not to excuse the driver who hit you. We make sure the question gets a fair answer.
What to Do With Your Helmet After a Crash
Get medical care and mention any blow to the head.
Concussions and brain injuries aren’t always obvious at the scene, even when the helmet did its job.
Keep the helmet exactly as it is.
Don’t clean it, repair it, or throw it away. Scrapes, cracks, and a broken strap show where and how hard you hit.
Photograph the DOT certification sticker and the inside label.
They’re your proof that the helmet met federal standards.
Keep your other gear too.
Jacket, gloves, boots, and eye protection tell the same story about the impact and about how carefully you ride.
Find your purchase records if you can.
A receipt or order confirmation helps show the helmet’s make, model, and age.
Don't answer an insurer's questions about your helmet.
How it fit, whether the strap was fastened, where you bought it: those questions are building a defense. Let us answer them.
What the Helmet Question Can, and Can't, Change
The driver's fault
A missing or non-compliant helmet doesn’t make a driver’s unsafe left turn or lane change any safer. Liability stays with the driver who caused the crash.
Compensation for head injuries
Not wearing a helmet may affect compensation where head injuries are involved. Insurers push that argument hard, and we make them prove it.
Your other injuries
Broken bones, road rash, and back and spinal injuries are valued on their own evidence. We don’t let a helmet argument discount the whole claim.
Your own coverage
If the at-fault driver’s policy is too small for your injuries, your uninsured/underinsured motorist coverage can fill the gap.
How We Answer the Helmet Defense
When an insurer raises the helmet, it’s usually trying to shift attention away from how the crash happened. We bring it back, and we meet the helmet argument with evidence rather than letting it hang over the case:
- Inspection of the helmet’s certification, fit, and damage
- Photos and records showing it was worn and fastened
- Crash reconstruction that puts the focus on the driver’s conduct
- Medical experts who explain how each injury happened
- A clear separation between head injuries and injuries a helmet has nothing to do with
- A product review when the helmet itself may have failed
If your helmet did fail, the manufacturer may share responsibility. We look at that possibility early, while the helmet is still intact.
California Motorcycle Helmet Law: The Basics
Every rider and passenger must wear one
California Vehicle Code Section 27803 requires motorcycle operators and passengers to wear a helmet, regardless of age or experience.
The helmet must meet federal standards
It must comply with U.S. Department of Transportation requirements and carry the DOT certification sticker. Federal Motor Vehicle Safety Standard 218 sets the minimums, including a thick protective inner liner, a sturdy chin strap, and no parts that protrude far beyond the shell.
It must fit and be fastened
A helmet that sits loosely or has an unfastened chin strap doesn’t meet the law, and it may not protect you.
A violation is not a waiver of your rights
Riding without a helmet can bring a ticket and fines. It does not bar an injury claim: under California’s pure comparative negligence rule, any share of fault only reduces your recovery.

San Jose Motorcycle Helmet Law FAQs
Does California require adult riders to wear helmets?
Yes. California requires every motorcycle operator and passenger to wear a helmet, regardless of age. It’s one of the states with a universal helmet law.
What makes a motorcycle helmet legal in California?
It must meet U.S. Department of Transportation standards and carry the DOT certification sticker. It should fit snugly and be fastened with the chin strap. Some non-certified helmets look almost identical to certified ones, so check for the sticker when you buy.
Can I still bring a claim if I wasn't wearing a helmet?
Yes. A missing helmet doesn’t excuse the driver who caused the crash. The insurer may argue it made head injuries worse and should reduce that part of your compensation, but it doesn’t erase your claim.
Do the helmet rules apply to passengers?
Yes. Passengers must wear a DOT-compliant helmet too, and it’s a violation for a rider to carry a passenger without one. An injured passenger can bring a claim against whoever caused the crash.
What if my helmet failed in the crash?
Keep it exactly as it is and call us. A helmet that cracked, broke apart, or came off despite being fastened may point to a defect, and the manufacturer or seller may share responsibility for your injuries.
I'm visiting from a state that doesn't require helmets. Does California's law apply to me?
Yes. Visitors must follow the laws of the state they ride in. Riding without a helmet in California can be used to argue you were partly responsible for your injuries.
Will the insurer ask about my helmet?
Almost certainly, and often early, in a recorded call. Don’t guess about fit, the strap, or where you bought it. Refer the adjuster to us.
What does it cost to talk to you?
Nothing. The consultation is free, and if you hire us, you pay no fee unless we recover compensation for you.
