Was I Partly at Fault? — Comparative Fault for Pedestrians and Cyclists in California

One of the most common reasons an injured pedestrian or cyclist never calls a lawyer is a simple, understandable assumption: I might have been partly at fault, so I probably don't have a case. In California, that assumption is usually wrong — and believing it can cost you real compensation you're legally entitled to.

California's Pure Comparative Fault Rule

In Li v. Yellow Cab Co. (1975) 13 Cal.3d 804, the California Supreme Court abolished the old "all-or-nothing" contributory negligence rule, under which a plaintiff who bore any fault at all for their own injury could be completely barred from recovering anything. In its place, the Court adopted a system of pure comparative fault: an injured person's damages are reduced in proportion to their own percentage of fault, but they are not barred from recovery no matter how large that percentage is. If you are found 30% at fault for an accident that caused $100,000 in damages, you can still recover $70,000. Even at 80% fault, you could still recover the remaining 20%.

This is a critically important distinction from many other states, some of which use a "modified" comparative fault system that cuts off recovery entirely once a plaintiff's fault reaches 50% or 51%. California has no such cutoff — the fault percentage affects how much you recover, not whether you can recover at all.

Common Fault Arguments Insurers Raise Against Pedestrians and Cyclists

Insurance adjusters representing at-fault drivers frequently raise a familiar set of arguments to try to shift blame onto an injured pedestrian or cyclist:

• "You weren't in a crosswalk." While Vehicle Code Section 21950 (full text)(Current as of 2026. Laws are subject to legislative change.) requires drivers to yield to pedestrians in marked and unmarked crosswalks, being outside a crosswalk does not eliminate a driver's general duty to avoid hitting a person they can see or should see in the roadway. This argument is also weaker than it used to be — see the discussion of the Freedom to Walk Act below. This fact may still affect the fault split in some circumstances, but it rarely eliminates the claim.
• "You weren't wearing a helmet." A missing helmet has no bearing on whether a driver caused the initial collision — it is not a cause of the crash itself, though it could theoretically be raised regarding the extent of certain injuries, a separate and more limited argument.
• "You were riding at night without proper lights or reflectors." This can be a legitimate factor in the fault analysis, particularly if visibility was a genuine issue, but it is weighed against the driver's own duty to watch for cyclists and travel at a safe speed for conditions.
• "You darted into the road." Vehicle Code Section 21950(b) does impose a duty on pedestrians not to suddenly leave a place of safety and enter the path of a vehicle that is so close as to constitute an immediate hazard — but this is a fact-specific inquiry, not an automatic bar, and drivers retain an independent duty to exercise due care.

Recent Legislative Changes Worth Knowing

California has updated several of the underlying rules discussed above in ways that generally favor injured pedestrians and cyclists, and that weaken some of the fault arguments insurers have traditionally relied on:

• Jaywalking is now largely decriminalized. Assembly Bill 2147, the "Freedom to Walk Act," took effect January 1, 2023. It generally prohibits law enforcement from stopping or citing a pedestrian for crossing outside a marked crosswalk unless a reasonably careful person would recognize an immediate danger of a collision. Crossing outside a crosswalk is no longer, by itself, an automatic traffic violation in most situations — which further weakens an insurer's argument that doing so was negligent per se.
• Drivers must change lanes to pass a cyclist, not just leave three feet. Assembly Bill 1909, the "OmniBike Bill," expanded on California's prior three-foot passing rule. Where an adjacent lane is available, a driver overtaking a cyclist traveling in the same direction must move into that lane, rather than simply passing within the same lane while leaving three feet of clearance — a more concrete, easier-to-enforce standard than measuring distance.
• Cyclists can cross on a pedestrian WALK signal. Also under AB 1909, effective January 1, 2024, a cyclist facing a pedestrian control signal may cross when the "WALK" signal is illuminated, rather than needing to wait for a green traffic light — expanding cyclists' right-of-way protections at signaled intersections.

Why Insurers Push Hard on Fault Percentages

Because California's system reduces damages proportionally rather than eliminating claims entirely, insurers have a strong financial incentive to argue for the highest possible fault percentage against an injured pedestrian or cyclist — every additional percentage point shifted onto you directly reduces what the insurer has to pay. This is precisely why an independent, thorough investigation of the actual facts — witness statements, available video, the physical evidence at the scene, and applicable traffic laws — matters so much in these cases. A properly documented claim can meaningfully shift the fault allocation back toward where it actually belongs.

What This Means for Your Claim

If you were hit by a car while walking or biking and you're worried that something you did — jaywalking, not wearing a helmet, being on your phone — means you have no case, the reality under California law is usually more favorable than you'd expect. The right question isn't "was I at fault," but "how much is the driver's share of fault worth, and how do we prove it."

How to Protect Your Claim If You Might Share Some Fault

1. 1. Do not assume you have no caseEven if you weren't in a crosswalk, weren't wearing a helmet, or think you may have contributed to the accident, California law still allows you to recover a proportional share of your damages.
2. 2. Get a police reportAn officer's assessment of the scene, statements, and any citations issued are important early evidence, even if the report assigns you some fault.
3. 3. Document the driver's conductSpeeding, distraction, failure to signal, and similar driver behavior can significantly affect the fault allocation in your favor, even where you also share some responsibility.
4. 4. Photograph the scene and any relevant conditionsLighting, weather, signage, and road markings can all affect how fault gets allocated.
5. 5. Seek medical attention and follow through with treatmentGaps in treatment can be used to argue your injuries were less serious, separate from the fault question.
6. 6. Consult an attorney before accepting any settlement or fault determinationInsurers frequently overstate a pedestrian's or cyclist's share of fault to reduce payouts — an attorney can push back with the actual legal standard and evidence.
