Negligence is at the heart of nearly every personal injury case. Whether you were injured in a car accident in Phoenix, slipped and fell at a store in Tucson, or suffered harm from unsafe conditions on another person’s property, your ability to recover compensation usually depends on proving negligence.
This article will look at the key elements of negligence under Arizona law, including duty of care, breach, causation, and damages. We’ll also explain how comparative negligence can affect your claim and what evidence is needed to prove liability in a personal injury case.
What Is Negligence?

In the legal sense, negligence occurs when someone fails to exercise the level of care that a reasonably prudent person would under similar circumstances. It is not about intentional harm but about carelessness or recklessness that leads to another person’s injuries.
For example, a distracted driver who runs a red light, a property owner who ignores broken stairs, or a business that fails to clean up a dangerous spill may all be considered negligent if their actions (or inactions) result in an accident.
The Four Elements of Negligence
To win a personal injury case based on negligence in Arizona, you must prove four essential elements:
- Duty of Care: The defendant owed you a legal duty to act with reasonable care. Drivers owe a duty to follow traffic laws, store owners owe a duty to keep their premises safe, and doctors owe a duty to treat patients according to professional standards.
- Breach of Duty: You must show that the defendant breached this duty by acting unreasonably or failing to act when required. Examples include speeding, failing to put up a “wet floor” sign, or ignoring medical protocols.
- Causation: There must be a direct link between the defendant’s breach of duty and your injury. If you slipped because of a wet floor with no warning sign, the lack of warning is the cause of your injury.
- Damages: Finally, you must prove that you suffered actual harm, such as medical bills, lost income, pain and suffering, or permanent disability.
Without evidence of all four elements, a negligence claim cannot succeed. This is why accident reports, witness statements, medical records, and expert testimony are so important in Arizona personal injury cases.
Arizona’s Comparative Negligence Law
Even if the injured person shares some responsibility for the accident, they may still recover compensation under Arizona’s comparative negligence system. Arizona follows a pure comparative negligence rule. This means that your compensation is reduced by the percentage of fault assigned to you, but you are not barred from recovery unless you are found 100% at fault.
For example, if you were awarded $100,000 in damages but were found 20% at fault for the accident, your award would be reduced to $80,000. This rule ensures that even partially at-fault victims can still recover fair compensation for their injuries.
Common Examples of Negligence in Arizona
Negligence can appear in many different scenarios.
Some of the most common examples in Arizona personal injury cases include:
- Motor vehicle accidents: Distracted driving, speeding, running red lights, or driving under the influence.
- Premises liability: Slips and falls in stores, inadequate security at apartment complexes, or unsafe conditions at public venues.
- Medical malpractice: Misdiagnosis, surgical errors, medication mistakes, or failure to follow accepted standards of care.
- Product liability: Manufacturers failing to design safe products, issue recalls, or provide proper warnings.
These examples show how broad negligence can be. Each case requires an in-depth look at whether a duty of care existed, whether it was breached, and how that breach caused the injury.
Damages Available in a Negligence Case
When negligence is proven, Arizona law allows injured victims to recover damages meant to make them whole again.
These damages generally fall into two categories:
- Economic damages: Medical bills, rehabilitation costs, lost wages, reduced earning capacity, and property damage.
- Non-economic damages: Pain and suffering, emotional distress, loss of enjoyment of life, and permanent disability or disfigurement.
In rare cases involving extreme recklessness or intentional misconduct, punitive damages may also be awarded to punish the wrongdoer and deter similar behavior.
The Statute of Limitations in Arizona
Another critical aspect of negligence law is the timeframe for filing a claim. Most personal injury lawsuits in Arizona must be filed within two years from the date of the injury. If you fail to file within this deadline, you may lose your right to pursue compensation altogether. There are limited exceptions for minors or cases where the injury was not immediately discoverable, but the two-year period is the general rule.
Because evidence can be lost and memories fade over time, it is best to contact a personal injury lawyer as soon as possible after an accident. Acting early allows your attorney to preserve evidence, interview witnesses, and ensure your claim is filed within the statutory deadline.
How an Arizona Personal Injury Lawyer Proves Negligence
Successfully proving negligence requires a combination of legal knowledge and practical investigation.
Here are some of the steps an attorney may take:
- Collecting accident reports, photographs, and surveillance footage.
- Interviewing eyewitnesses and obtaining sworn statements.
- Consulting with experts such as accident reconstructionists, medical specialists, or engineers.
- Reviewing medical records and coordinating with healthcare providers to document injuries.
- Negotiating aggressively with insurance companies to secure a fair settlement.
- Preparing the case for trial if the insurer refuses to offer adequate compensation.
By handling the legal process, a lawyer allows you to focus on recovery while ensuring your rights are protected.
