Negligence is the failure to use the reasonable care that a sensible person would use in the same situation, and it sits at the center of almost every Arizona injury claim. When another person's carelessness causes a crash, a fall, or another accident, negligence is the legal theory that lets you hold them financially responsible. Understanding it matters because insurance companies build their entire strategy around shifting blame onto you.
At Hartley Law Car Accident & Injury Lawyers, we help injured people in Phoenix cut through that tactic and pursue the compensation the law allows. If someone else's carelessness left you hurt, our team is ready to review what happened and explain your options at (602) 529-2222.
Negligence happens when someone owes you a duty to act carefully, fails to meet that duty, and causes you harm as a result. The law does not require perfection from anyone. It simply asks people to behave the way a reasonably careful person would under similar circumstances.
That reasonable care standard is the backbone of personal injury law in Arizona. A driver who checks mirrors, obeys traffic signals, and slows in bad weather is acting reasonably. A driver who speeds through a red light while texting is not.
When someone falls short of that standard and injures another person, they can be held liable, meaning legally and financially responsible. This is why negligence drives the majority of injury claims we handle at Hartley Law, from rear-end collisions to slip and fall accidents on poorly maintained property.
To win compensation, you cannot simply say the other person was careless. Arizona law requires proof of four specific elements, and each one must be supported by evidence:
If any one of these elements is missing, the claim fails. Consider a common example. A delivery driver rolls through a red light in Phoenix and strikes your car. The driver owed you a duty, breached it by ignoring the signal, caused the collision, and left you with a broken wrist and hospital bills. All four elements are present, which is what makes the claim viable.
After a crash or fall, the burden of proof rests on you, the injured person. That means our team must show, more likely than not, that the other party's negligence caused your injuries. This standard is lower than the one used in criminal cases, but insurers still fight hard to defeat it.
Evidence is what turns a story into a provable claim. Police reports, photographs, medical records, witness statements, and traffic camera footage all help establish duty, breach, and causation. The sooner this evidence is gathered, the stronger your position becomes, because physical proof and memories fade quickly.
At Hartley Law, we build claims by tying each piece of evidence back to a specific element of negligence. When an insurer argues that a breach did not cause your injury, we answer with expert analysis that connects the accident to your medical diagnosis.
Negligence is easier to understand when you see how it plays out in real accidents. The same four elements apply whether you were hurt on the road, on someone else's property, or by a careless professional. What changes is the kind of duty involved and the evidence needed to prove a breach.
Across the injury claims we handle at Hartley Law, a few situations come up again and again:
Each of these examples shares the same legal backbone, yet the proof looks different in every case. A rear-end collision may turn on a police report and phone records, while a fall claim may depend on maintenance logs and surveillance footage. Knowing which evidence matters for your specific accident is where our team focuses first.
That focus also shapes how we respond to an insurer's defense. When an adjuster claims the hazard was obvious or that you should have seen it coming, we return to the elements and show how the other party breached its duty. Tying the facts of your accident to a clear standard of care is what keeps a claim from unraveling under pressure.
Arizona uses a system called pure comparative negligence, set out in Arizona Revised Statutes § 12-2505. Under this rule, sharing part of the blame does not bar you from recovering compensation. Instead, your recovery is reduced by your percentage of fault.
Here is how the math works. Suppose your total damages are $100,000 and a jury finds you 20 percent responsible for the accident. Your recovery is reduced by that 20 percent, leaving you with $80,000. Arizona is one of the few states where you can recover even if you were 99 percent at fault, though the reduction at that level is steep.
There is one important limit. The statute provides no right to comparative negligence for a person who intentionally, willfully, or wantonly caused the harm. This is why insurance adjusters work so aggressively to inflate your share of fault, because every percentage point they assign to you shrinks what they must pay. Fighting those fault percentages is one of the most valuable things our team does for injured clients.
Not all negligence looks the same, and the type involved can change how a claim proceeds. The most common forms we see include the following:
Identifying the correct type early helps our team frame the claim and anticipate the defenses an insurer is likely to raise. Each category carries different proof requirements and, in some cases, different exposure for the at-fault party.
Time is a critical factor in every negligence claim. In Arizona, the statute of limitations for most personal injury cases is two years from the date of injury under Arizona Revised Statutes § 12-542. If you miss that deadline, the court will almost certainly dismiss your case regardless of how strong it is.
Certain situations carry even shorter windows. Claims against a city, county, or state agency require a formal Notice of Claim within 180 days of the injury under Arizona Revised Statutes § 12-821.01. Missing that earlier deadline can end a claim against a public entity before the two-year clock ever runs out.
Preserving evidence and acting quickly protect both your deadline and your leverage. When the Hartley Law team steps in early, we can secure footage before it is erased, document injuries while they are fresh, and push back on the fault-shifting that comparative negligence invites.
Negligence is the failure to use reasonable care, resulting in harm to another person. It forms the legal basis for most personal injury claims in Arizona.
The four elements are duty, breach, causation, and damages. You must prove all four to hold an at-fault party responsible for your injuries.
Yes. Under Arizona's pure comparative negligence rule in Arizona Revised Statutes § 12-2505, your recovery is reduced by your fault percentage but not barred, even if you were mostly at fault.
Ordinary negligence is a simple failure to use reasonable care. Gross negligence is a reckless or extreme disregard for the safety of others.
Most personal injury claims must be filed within two years of the injury under Arizona Revised Statutes § 12-542. Claims against public entities have shorter deadlines.
The injured person carries the burden of proof. You must show it is more likely than not that the other party's negligence caused your injuries.
Facing an insurance company that wants to pin the blame on you is frustrating, especially when Arizona's pure comparative negligence rule means every percentage point of fault reduces what you can recover. You do not have to sort out duty, breach, and causation on your own.

Our team, led by attorney Matt Hartley, focuses on building claims that connect hard evidence to each element of negligence, so insurers cannot shift responsibility onto you without a fight. We evaluate how the two-year deadline under Arizona Revised Statutes § 12-542 applies to your situation and move quickly to protect your options.
