Bicycle Accident Lawyer California: Claims & Fault
California cyclists have the same road rights as drivers. Here is how fault, insurance, and filing deadlines really work after a bike crash.

You were riding legally, in the bike lane or the right-hand portion of the road, and a driver turned across your path, drifted into you, or flung a door open without looking. Now you have a broken collarbone, a totaled bike, and an insurance adjuster suggesting the crash was somehow your fault.
California gives cyclists real legal protection — but the burden is on you to document what happened and act before the deadlines run. Here is how bicycle injury claims actually work in this state, and when a bicycle accident lawyer in California is worth calling.
Cyclists Have the Same Road Rights as Drivers
Under California Vehicle Code section 21200, a person riding a bicycle on a public roadway has all the rights — and all the duties — of the driver of a vehicle. That single sentence is the foundation of most bicycle injury claims. A driver who fails to yield to you owes you the same duty of care they would owe another car.
Several other rules come up constantly in these cases:
- CVC 21760 (Three Feet for Safety Act) — a motorist passing a cyclist in the same direction must leave at least three feet of clearance. Since AB 1909 took effect, drivers must also change lanes to pass a bicyclist whenever it is feasible to do so.
- CVC 22517 ("dooring") — no one may open a car door on the traffic side unless it is reasonably safe. Dooring cases are often the most clear-cut liability claims we see.
- CVC 21202 — cyclists generally ride as near the right side as practicable, but the statute has broad exceptions: passing, turning left, avoiding hazards, and lanes too narrow to share safely. Adjusters frequently ignore those exceptions.
- CVC 21212 — riders under 18 must wear a helmet. There is no adult helmet requirement in California, and going without one is not automatically negligence — though insurers still try to argue it.
- Since January 1, 2024, bicyclists may cross an intersection on a pedestrian walk signal, not only on a green light.
You can read the statutes yourself at California Legislative Information, and the California DMV publishes a plain-language summary of bicycle rules of the road.
Proving Fault After a Bike Crash
Bicycle cases are won on evidence gathered in the first days, because bikes get thrown away, bruising fades, and drivers change their story.
What actually moves a claim
- The traffic collision report. Request it, read it, and check whether the officer interviewed independent witnesses or only the driver.
- Independent witnesses. Get names at the scene if you can. Bystanders who saw a driver's turn signal — or absence of one — are often decisive.
- Video. Doorbell cameras, business security cameras, transit buses, and helmet or handlebar cams. Most systems overwrite within 7 to 30 days.
- The bicycle itself. Do not repair or discard it. Damage patterns show impact direction and speed.
- Photos of the scene, sightlines, road defects, your injuries, and the driver's vehicle.
- Immediate medical care. A gap between the crash and your first treatment is the single most common argument used to devalue an injury claim.
If the roadway or a defect caused the crash
Claims involving a pothole, a sewer grate, unsafe construction plating, or a poorly designed intersection may be against a city, county, or the state — and those follow a much shorter deadline (see below).
California's Comparative Fault Rule Works in Your Favor
California uses pure comparative negligence. If you are found partly responsible — riding without lights at night, or rolling a stop sign — your recovery is reduced by your percentage of fault, but it is not eliminated. A rider found 30% at fault on a $100,000 case still recovers $70,000.
This matters because insurers routinely open with an inflated fault percentage. Pushing that number down is often where most of the value in a bicycle claim is created.
One point many cyclists do not know: Proposition 213, which bars uninsured drivers from recovering pain-and-suffering damages, is aimed at people operating uninsured motor vehicles. A person riding a bicycle is generally not in that category — but the analysis is fact-specific, so confirm it with a lawyer for your situation.
Who Pays for a Bicycle Accident Injury
There is usually more than one source of recovery, and identifying all of them is part of the job:
- The at-fault driver's liability insurance. California's minimum limits are low relative to serious orthopedic or head injuries, so they are often exhausted quickly.
- Your own uninsured/underinsured motorist (UM/UIM) coverage. This is the one people miss. If you own a car, your auto policy's UM/UIM coverage typically protects you while you are riding a bicycle, including in a hit-and-run. Check your declarations page.
- Medical payments (MedPay) coverage on your auto policy, which pays regardless of fault.
- Health insurance, which usually pays first and then asserts a lien to be repaid out of your settlement — a negotiation point that directly affects what you keep.
- A government entity where a dangerous road condition contributed to the crash.
Compensation in a bicycle claim generally covers medical bills incurred and expected, lost wages and reduced earning capacity, pain and suffering, and the replacement value of your bike and gear. Anyone who quotes you a specific dollar figure before reviewing your records is guessing.
Deadlines You Cannot Miss
In California, the statute of limitations for most personal injury claims — including bicycle crashes — is two years from the date of injury (Code of Civil Procedure section 335.1).
If your claim is against a public entity — a city, county, transit agency, school district, or Caltrans — you must first file an administrative claim, generally within six months of the incident, before you can sue. Miss that window and the claim is usually gone regardless of how strong it was.
Different rules can apply to minors, wrongful death, and claims discovered later. Deadlines are unforgiving, so verify yours for your specific facts rather than relying on a general article. The California Courts Self-Help Center has an overview of the civil process.
Frequently Asked Questions
Does car insurance cover a bicycle accident?
Often, yes — but not in the way people expect. The at-fault driver's liability policy is the primary source. Separately, your own auto policy's uninsured/underinsured motorist and MedPay coverage usually follows you onto a bicycle, which is critical if the driver flees or carries minimum limits.
What should I do right after a bicycle accident?
Call 911 and get a police report, exchange information, photograph everything, collect witness names, seek medical evaluation the same day, keep the damaged bicycle and clothing, and decline to give a recorded statement to the driver's insurer before you have talked to a lawyer.
Was it my fault if I wasn't wearing a helmet?
California only requires helmets for riders under 18. For adults, not wearing one does not make you at fault for a crash a driver caused, though an insurer may argue it contributed to head injuries. That argument is contestable.
How long does a bicycle accident claim take to settle?
It varies widely. Straightforward cases can resolve in a few months once treatment ends; cases involving surgery, disputed liability, or a lawsuit can take a year or more. Settling before you know your final medical picture is usually a mistake.
What if the driver fled the scene?
Report it immediately — a police report is typically required for an uninsured motorist hit-and-run claim. Your own UM coverage may then apply. Nearby cameras are often the best chance at identifying the vehicle, which is another reason to move quickly.
