California Comparative Negligence Explained

"It was partly my fault, so I probably can't recover anything." It is one of the most common — and most costly — misconceptions injured people have in California. The state's comparative negligence rule is more forgiving than many expect. This article explains how it works in plain language. It is general legal information, not legal advice.

What "pure comparative negligence" means

California follows a pure comparative negligence rule. If more than one party shares responsibility for an accident, each party's fault is expressed as a percentage, and an injured person's recovery is reduced by their own share of fault — but it is not eliminated, even if they were mostly at fault.

This rule comes from the California Supreme Court's decision in Li v. Yellow Cab Co. (1975), which replaced the older, harsher rule that barred recovery entirely if the injured person was even slightly at fault.

A simple example

Suppose your total damages — medical bills, lost wages, and pain and suffering — add up to $100,000. After reviewing the facts, a jury decides you were 20% at fault for the collision and the other driver was 80% at fault.

• Your damages: $100,000
• Your share of fault: 20%
• Your recovery is reduced by 20%, to $80,000

Under the pure rule, even someone found 90% at fault could still recover 10% of their damages. That is very different from states that cut off recovery at 50%.

How fault gets decided

Fault is rarely obvious. It is assessed from the evidence: the police or CHP report, photographs, vehicle damage, witness statements, traffic laws, and sometimes expert analysis. Understanding how fault is evaluated in California car accident claims is especially important because your percentage of fault directly reduces what you recover, and insurers have a strong incentive to argue that you were more responsible than you actually were.

Why this matters for your claim

Two practical lessons follow from the comparative negligence rule:

1. Do not assume you have no case just because you may have been partly at fault. You may still be entitled to a meaningful recovery.
2. Be careful what you say to insurers. A casual apology or an offhand "I didn't see them" can be used to push your fault percentage higher. Documenting the scene thoroughly helps counter an inflated fault argument.

Comparative fault comes up frequently in premises liability cases involving slips and falls, where property owners often argue the injured person should have been paying closer attention.

When to get guidance

If an insurer is blaming you, disputing how the crash happened, or assigning you a fault percentage that feels unfair, a free consultation can help you understand how the comparative negligence rule applies to your specific facts.
