Bicycle Accident Lawyer California: Your Rights

A right hook at a Los Angeles intersection. A car door flung open into a Sacramento bike lane. A driver who "never saw" the cyclist in the crosswalk. California riders get hurt in predictable ways — and insurance companies respond in predictable ways too, usually by suggesting the cyclist was where they shouldn't have been.

Knowing what California law actually requires of drivers, and what it requires of you, is the difference between a claim that gets taken seriously and one that gets lowballed. Here is how bicycle accident claims work in this state.

California Law Puts You on the Road, Not Beside It

Vehicle Code section 21200 gives a person riding a bicycle on the roadway all the rights and all the duties of a driver. You are traffic. That single provision defeats the most common insurance argument — that a cyclist is somehow an intruder in the lane.

Several other rules matter in nearly every case:

• Lane changing to pass. Since January 1, 2023, AB 1909 requires drivers to move into an adjacent lane to pass a bicyclist whenever it is reasonably safe to do so. Where changing lanes isn't possible, the older three-foot minimum under Vehicle Code 21760 still applies, and the driver must slow to a reasonable speed.
• Where you ride. Section 21202 asks riders moving slower than traffic to stay as near the right curb as practicable — but it lists express exceptions for passing, turning left, avoiding hazards (including parked cars and opening doors), and lanes too narrow to share safely. "As practicable" is not "hug the gutter."
• Dooring. Section 22517 bars anyone from opening a vehicle door into traffic until it is reasonably safe. A doored cyclist usually has a strong liability case against the person who opened the door.
• Walk signals. As of January 1, 2024, cyclists may legally enter an intersection on a pedestrian walk signal.
• Helmets. Required under Vehicle Code 21212 for riders under 18. Adults are not required to wear one, and not wearing a helmet does not bar an adult's claim — though insurers will raise it, particularly in head injury cases.

How Fault Gets Decided

California uses pure comparative negligence. If a jury finds you 20% responsible — say you were riding at dusk without a light — your recovery is reduced by 20%, not eliminated. Even a rider found mostly at fault can recover something. This is why you should never accept an adjuster's assertion that you "have no case."

Fault in these crashes typically traces back to a handful of driver behaviors: left turns across an oncoming cyclist, right hooks across a bike lane, unsafe passing, failure to yield when exiting a driveway, distracted driving, and impaired driving. Sometimes the responsible party isn't a driver at all. A dangerous roadway condition — a collapsed grate, an unrepaired pothole, a bike lane that dumps riders into a hazard — can support a claim against the city or county under Government Code section 835.

Evidence That Actually Moves a Claim

Cases are won with proof, not argument. The most valuable items are usually the hardest to get later: the responding officer's traffic collision report, nearby business or doorbell video (often overwritten within days or weeks), the damaged bicycle and helmet in their post-crash condition, your clothing, and photographs of the scene before anything is cleaned up or repaired.

What to Do After a Bicycle Crash

1. Call 911 and get a report. A documented police response makes it far harder for a driver to change their story.
2. Get medical attention the same day. Adrenaline masks injuries, and a treatment gap is the first thing an adjuster will point to.
3. Photograph everything — the vehicle, its license plate, the road, your bike, your injuries, and the sight lines.
4. Collect witness names and numbers. Bystanders disperse quickly and are rarely listed in full on the report.
5. Do not repair or discard your bicycle or helmet. They are physical evidence of impact forces.
6. Decline a recorded statement to the other driver's insurer until you have spoken with an attorney.

Which Insurance Policy Pays

More than one policy is often available, and riders routinely leave money on the table by not checking:

• The driver's liability coverage is the primary source. California's minimum bodily injury limit is modest, so it is frequently exhausted by a serious injury alone.
• Your own auto policy's uninsured/underinsured motorist coverage typically protects you while riding a bicycle — including in a hit-and-run — even though no car of yours was involved. This is the single most overlooked source of recovery in bike cases.
• MedPay on your auto policy can cover treatment regardless of fault.
• Health insurance pays initially but will usually assert a lien against your settlement.
• Homeowners or renters liability may apply if a non-driver (a pedestrian, a property owner, another cyclist) caused the crash.

What a Bicycle Accident Claim Is Worth

There is no calculator and no guaranteed figure. Value depends on the medical bills incurred and reasonably expected, lost income and lost earning capacity, the permanence of the injury, the strength of liability proof, and — very often the hard ceiling — the available policy limits.

Bicycle crashes skew severe because there is nothing between the rider and the vehicle. Fractures, shoulder and knee injuries, dental damage, road rash requiring grafts, and traumatic brain injuries are common, and the last category can dominate a case's value. Our page on how pain and suffering is calculated in California explains how non-economic damages are typically valued, and we handle the most serious of these as catastrophic injury claims.

Deadlines You Cannot Miss

In California, the general deadline to file a personal injury lawsuit is two years from the date of the crash (Code of Civil Procedure 335.1). Property damage claims generally allow three years.

The critical exception: if a government entity is responsible — a city that maintained a hazardous street, a public transit bus, a county vehicle — you must first file an administrative claim, generally within six months of the incident. Miss that window and the claim is usually gone regardless of how strong it was.

Deadlines shift for minors, for delayed discovery of an injury, and in other situations. Confirm your own dates early rather than assuming. The California Courts Self-Help Center offers general guidance on civil filing timelines.

Frequently Asked Questions

Does car insurance cover me if I'm hit while riding a bike?

Often, yes — but through a route most people don't expect. The at-fault driver's liability coverage pays first. If that driver is uninsured, underinsured, or flees the scene, your own auto policy's uninsured motorist coverage generally extends to you as a cyclist. You do not need to have been in a car for it to apply.

Can I still recover if I wasn't wearing a helmet?

Yes. Adults in California are not legally required to wear a helmet, and the absence of one does not bar a claim. Expect the insurer to argue it reduced your recovery in a head injury case; that argument is contested, and it does not eliminate liability for the crash itself.

What if the driver who hit me took off?

Report the hit-and-run to police immediately and get the report number. Then notify your own insurer promptly — uninsured motorist coverage is designed for exactly this situation, but policies impose short notice deadlines, and in some cases physical contact must be documented.

How long does a bicycle accident claim take to settle?

A straightforward claim with completed treatment may resolve in a few months. Cases involving surgery, disputed fault, a government defendant, or litigation commonly run a year or longer. Settling before you know the full extent of your injuries is almost always a mistake.

Do I have a case if I was partly at fault?

Probably. Under California's pure comparative negligence rule, your percentage of fault reduces your recovery but does not eliminate it. Adjusters frequently overstate a rider's share of blame early on, before the evidence is in.
