When an injury occurs in California, whether from a freeway collision, a fall in a store, or a workplace accident. one question often proves decisive: Did another party owe a duty of care, and was that duty breached?
Duty of care lies at the core of California’s personal injury framework. It is the standard on which liability rests, shaping how courts, insurers, and juries determine accountability and compensation.
In 2025, with new reforms refining evidentiary rules and consumer protections, understanding this principle has become essential for injury victims, attorneys, and legal professionals alike. This article examines duty of care in depth and its role within California’s evolving personal injury law.
Personal injury law in California rests on three core principles:
California Civil Code § 1714 codifies this foundation:
“Every one is responsible, not only for the result of his willful acts, but also for an injury occasioned to another by his want of ordinary care or skill in the management of his property or person, except so far as the latter has, willfully or by want of ordinary care, brought the injury upon himself.”
Recent updates in 2025, such as stricter rules for medical billing transparency under Assembly Bill 123 and broader acceptance of digital evidence following key appellate rulings, reflect California’s ongoing effort to refine how these principles are applied.

In plain terms, duty of care means a person or entity must act reasonably to prevent foreseeable harm to others. The level of duty depends on the situation:
The Judicial Council of California explains it clearly in its Civil Jury Instructions (CACI No. 401):
“Negligence is the failure to use reasonable care to prevent harm to oneself or to others. A person can be negligent by acting or by failing to act. A person is negligent if they do something that a reasonably careful person would not do in the same situation, or fail to do something that a reasonably careful person would do in the same situation.”
This “reasonable person standard” is what juries use to decide whether a duty of care was breached.
Failure in any of these duties, texting while driving, ignoring a broken stair, failing to train employees, or misdiagnosing an illness, can open the door to liability.
While the existence of a duty is clear in many common scenarios like driving or owning a business, it can be more complex in others. California courts use a multi-factor test to determine if a duty of care exists where one isn't automatically presumed. Key factors include:
In Brown v. USA Taekwondo (2021), the California Supreme Court reaffirmed this approach:
“…the foreseeability of harm to the plaintiff, the degree of certainty that the plaintiff suffered injury, the closeness of the connection between the defendant’s conduct and the injury suffered, the moral blame attached to the defendant’s conduct, the policy of preventing future harm, the extent of the burden to the defendant and consequences to the community of imposing a duty to exercise care with resulting liability for breach, and the availability, cost, and prevalence of insurance for the risk involved.”
This nuanced legal analysis ensures that duty of care is not applied arbitrarily but is grounded in fairness and sound public policy, especially in novel or unusual cases.
To succeed in a negligence claim, an injury victim in California must prove four elements:
Take this example: A store owner fails to clean up a spill for hours. A customer slips, breaks a wrist, and faces thousands in medical bills. Here, duty (keeping floors safe), breach (ignoring the spill), causation (the fall caused the injury), and damages (medical bills and pain) all line up, making it a strong negligence case.
California’s pure comparative fault rule adds nuance to duty of care. Even if the injured person shares responsibility, they can still recover damages.
For instance, imagine a pedestrian who jaywalks but is hit by a speeding driver. A jury might find the pedestrian 40% responsible and the driver 60% responsible.
If damages total $100,000, the pedestrian could still recover $60,000. This rule highlights how duty of care is rarely one-sided, multiple parties can bear legal responsibility.
Some California cases bypass the need to prove a breach of duty. Under strict liability, a defendant can be held responsible simply because harm occurred under specific circumstances:
Strict liability reflects the idea that certain risks are so significant that the law imposes automatic responsibility, reinforcing the protective nature of California’s personal injury system.
While most damages in personal injury cases are compensatory, California law permits punitive damages in limited circumstances.
These awards are reserved for conduct that is especially egregious, marked by malice, oppression, or fraud and serve a purpose distinct from compensation.
For example, a carrier that knowingly dispatches trucks with defective brakes, or a corporation that conceals evidence of toxic contamination, may be exposed to punitive damages. The objective is not to reimburse the plaintiff but to punish wrongful conduct and deter similar behavior in the future.
Victims in California can seek three main categories of damages:
The scope of damages ties back to duty of care, the more severe the breach, the more expansive the compensation may be.
In most cases, insurance companies are the gatekeepers of compensation. Auto insurers, homeowners’ insurers, and commercial liability carriers often control settlement negotiations.
But insurers are not neutral. Their duty is to their shareholders, not the victim. That’s why victims must be cautious when providing statements or accepting early settlement offers.
California’s 2025 reforms tightened bad faith insurance laws, giving victims stronger grounds to challenge unfair delays or denials. Still, proving duty of care often becomes the leverage point in negotiations.
When cases go to trial, California juries play a decisive role. Jurors evaluate:
Jurors also apply comparative fault, sometimes splitting percentages of blame across multiple parties. Because of this, jury trials are unpredictable, making strong evidence of duty and breach critical.
Victims can’t wait indefinitely to bring a claim. California generally imposes a two-year statute of limitations from the date of injury.
Exceptions apply, for example, medical malpractice or claims against government agencies have different deadlines. Failing to file within the legal time limit typically bars recovery, even when a breach of duty is clear.
Each example shows how the law adapts duty of care standards to different contexts, always focusing on whether harm was reasonably preventable.
Lawmakers in Sacramento have introduced several reforms reshaping how duty of care and personal injury cases are litigated:
These reforms reflect California’s broader push to level the playing field between individuals and powerful corporations or insurers.
In a state as large and diverse as California, millions of residents interact daily in ways that can lead to accidents—on freeways, in offices, at medical clinics, or even at home through defective consumer goods.
Duty of care serves as the legal thread tying all these situations together. Without it, victims would face uphill battles for compensation. With it, they have a framework to demand accountability.
Duty of care remains the defining standard in California personal injury law. It governs liability across settings, whether in traffic collisions, premises accidents, or professional negligence and provides the framework by which courts, insurers, and juries allocate responsibility.
With the 2025 reforms strengthening evidentiary rules and consumer protections, this principle has only grown in importance.
For practitioners and claimants alike, a clear understanding of duty of care is essential to protecting rights, ensuring accountability, and achieving just outcomes in California’s evolving legal landscape.
What is duty of care in California personal injury law?
Duty of care means individuals and businesses must act reasonably to avoid causing harm to others. In California, proving a personal injury case requires showing that the defendant owed you this duty, breached it, and caused your injuries. The specific duty varies depending on the situation—for example, drivers must obey traffic laws, property owners must maintain safe premises, and doctors must follow professional standards of care.
How do I know if I have a valid personal injury case in California?
To determine if you have a case, you must be able to prove that the four elements of a negligence claim are met: (1) the defendant owed you a duty of care, (2) they breached that duty, (3) the breach caused your injuries, and (4) you suffered measurable damages. A legal professional can help you evaluate the facts of your situation to see if these elements can be proven with evidence.
How long does a personal injury case take to settle?
The timeline for a personal injury case varies significantly. Simple claims, like minor fender-benders, might settle in a few months. More complex cases involving serious injuries, disputes over fault, or large corporations can take a year or more, especially if a lawsuit needs to be filed. The goal is to ensure a fair settlement, which sometimes requires patience.
What should I do after a car accident in California?
First, check for injuries and call 911 if necessary. If you are able, document the scene by taking photos and videos of the vehicles, the road, and any hazards. Exchange information with the other driver and get contact details for any witnesses. Do not admit fault or apologize, and seek immediate medical attention, even if you don't feel hurt.
How much is a personal injury case worth?
There is no average value for a personal injury case. Your potential compensation depends entirely on the specific damages you suffered. This includes quantifiable costs (economic damages) like medical bills and lost wages, as well as subjective losses (non-economic damages) such as pain and suffering. The final amount is heavily influenced by the severity of your injuries and the strength of the evidence.
