What the Helmet Law Means Before and After a Crash
A motorcycle can’t shield its rider the way a car’s frame does. When a bike and a car or truck collide, the rider’s head is often what’s most at risk, and traumatic brain injuries are among the most devastating results. That’s why California requires everyone on a motorcycle to wear an approved helmet.
After a crash, the helmet question takes on a second role. Insurers use it to argue that your injuries, or some of them, are partly your own responsibility. Talk to us if:
You were injured by a driver while riding or as a passenger
You weren't wearing a helmet, or it came off in the crash
The insurer is asking whether your helmet was approved or properly fastened
You've been told a missing helmet means you have no case
It doesn’t. A missing helmet can affect how much you recover, but it doesn’t take away your right to bring a claim.
When the Insurer Brings Up Your Helmet
Get your head and neck checked, even with no obvious injury.
A doctor’s findings separate the injuries a helmet relates to from the ones it doesn’t.
Keep the helmet, or write down what happened to it.
If it cracked, came off, or was lost at the scene, record that while you remember it clearly.
Note the helmet's make, model, and any certification label.
If you weren’t wearing one, don’t guess or explain in writing. Just keep the facts straight.
List every injury separately.
A broken leg or road rash on your arms has nothing to do with a helmet. Your claim shouldn’t treat them as if they do.
Don't accept a "helmet discount."
An early offer that knocks off a percentage for the helmet is an opening position, not the law.
Let us answer the helmet questions.
How the helmet fit and whether it was fastened are fault questions. We respond to them with evidence.
How a Missing Helmet Can, and Can't, Affect Compensation
Your right to sue stays intact
Not wearing a helmet shouldn’t stop you from pursuing a claim against the driver who caused the crash.
Head and face injuries may be reduced
A court can lower damages by the share of a head injury or facial lacerations that a helmet would likely have prevented.
Everything else is judged on its own
Broken bones, back injuries, road rash, lost wages, and pain and suffering from other injuries aren’t reduced because of a helmet.
Your passenger's claim
A passenger can bring their own claim against the at-fault driver, and depending on the facts, against others involved.

How We Keep the Helmet Question in Proportion
The helmet doesn’t change how the crash happened. We keep the focus on the driver’s conduct first, then deal with the helmet argument on the evidence, with expert witnesses where the injuries call for it:
- Investigation and reconstruction of what the driver did to cause the crash
- Medical experts who explain which injuries a helmet could, and couldn’t, have prevented
- Inspection of the helmet’s condition, fit, and approval where it was worn
- Witness and scene evidence showing how you were riding
- A full account of every injury, not just head injuries
When the helmet did its job but you were still hurt, that’s evidence too: it shows the force the driver’s mistake put through your body.
California's Helmet Law in Plain Terms
A universal requirement
Some states only require helmets for younger riders. California requires every motorcycle driver and passenger to wear one, regardless of age. Under Vehicle Code Section 27803, the rule applies to motorcycles and motorized bicycles.
Approved, strapped, and snug
The helmet must be an approved safety helmet, fastened with its straps, and fit the head securely.
A citation, not a forfeit
Riding without an approved helmet can bring a citation and a fine. It doesn’t bar an injury claim.
Pure comparative fault
California assigns each party a percentage of responsibility and reduces damages by the injured person’s share. Even a rider found partly responsible can still recover from the driver who hit them.

Sunnyvale Motorcycle Helmet Law FAQs
Do adult riders in Sunnyvale have to wear a helmet?
Yes. California has a universal helmet law, so every rider and passenger must wear an approved helmet, whatever their age.
Does the helmet law apply to motorized bicycles?
Yes. The helmet requirement covers riders of motorized bicycles as well as motorcycles.
I wasn't wearing a helmet. Can I still sue the driver who hit me?
Yes. Not wearing a helmet shouldn’t stop you from bringing a claim. The insurer may argue it reduces what you can recover for head or facial injuries.
How much can a missing helmet reduce my compensation?
There’s no fixed percentage. Under comparative fault, a court may reduce damages by the amount a helmet would likely have reduced the injuries it relates to. Other injuries shouldn’t be affected. Medical and expert evidence decides the question.
What if I was wearing a helmet and still got a head injury?
You have the same claim as any injured rider. A helmet reduces the risk of a serious head injury; it can’t eliminate it. The driver who caused the crash is responsible for the harm.
What's the penalty for riding without a helmet?
A citation and a fine. That’s separate from your injury claim.
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.
