“It was partly my fault. Do I even have a case?” It is one of the most common questions injured drivers ask, and the honest answer in Arizona is usually yes.
Many people walk away from valid claims because they assume that sharing any blame means getting nothing. In Arizona, that assumption is wrong. The state follows one of the most forgiving fault rules in the country, and understanding it can be worth a great deal of money to you.
This page explains Arizona’s pure comparative negligence rule in plain English, with simple examples, and shows you how insurance companies use fault percentages to shrink payouts, and how a good lawyer pushes back.
What Pure Comparative Negligence Means
Arizona follows pure comparative negligence under A.R.S. § 12-2505. The rule has two parts:
- You can recover compensation even if you were partly at fault. In theory, you could recover even if you were 99% at fault.
- Your recovery is reduced by your percentage of fault. Whatever share of the blame is assigned to you comes straight off the top of your compensation.
So fault in Arizona is not a yes-or-no question. It is a percentage, and that percentage becomes the single most important number in your case after the value of your damages.
Worked Examples: How the Math Plays Out
These are hypothetical examples for illustration only, but they show exactly how the rule works.
Example 1: You are 20% at fault
Suppose your total damages, including medical bills, lost wages, and pain and suffering, are $100,000. The insurance company, or eventually a jury, decides you were 20% at fault because you were driving slightly over the speed limit when the other driver turned in front of you.
Your recovery is reduced by your share: $100,000 minus 20% leaves $80,000.
Example 2: You are 50% at fault
Same $100,000 in damages, but this time fault is split evenly. You still recover: $100,000 minus 50% leaves $50,000. In many other states, being 50% or more at fault would leave you with nothing. Not in Arizona.
Example 3: You are mostly at fault
Now suppose you were found 70% at fault for the same $100,000 in damages. Even then, Arizona’s pure rule lets you recover the remaining 30%, or $30,000. It is a smaller recovery, but it is not zero, and after a serious injury, that difference matters.

How Insurance Companies Use Fault Percentages Against You
Here is the part insurers do not advertise: every percentage point of fault they assign to you is money they do not have to pay. That gives adjusters a built-in reason to inflate your share of the blame.
Common tactics include:
- Mining your recorded statement. Innocent phrases like “I didn’t see him” or “I’m sorry” get treated as admissions of fault.
- Cherry-picking the police report. An adjuster may seize on any note that suggests you contributed to the crash, while downplaying everything that points at their driver.
- Blaming your speed, following distance, or attention. Even without hard evidence, adjusters often assert that you “could have avoided” the crash.
- Using the seat belt issue. Arizona’s seat belt law is secondary enforcement for adults, but failure to wear one can be raised to reduce your damages in some cases.
Remember the math from the examples above. On a $100,000 claim, moving you from 10% at fault to 40% at fault saves the insurer $30,000. Fault percentages are negotiated, not handed down from on high, and the insurer negotiates for a living.
How Fault Is Actually Decided
There is no formula that spits out a fault percentage. Fault is argued, using evidence:
- The police report and any citations issued
- Photos and video of the vehicles, the scene, and skid marks
- Witness statements
- Vehicle damage patterns, which can show angles and speeds
- Traffic laws that applied, such as right-of-way and signal rules
- In larger cases, accident reconstruction experts
During settlement talks, the two sides argue their versions and usually land on a negotiated number. If the case goes to trial, the jury assigns the percentages. Because most cases settle, the strength of your evidence and the credibility of your arguments drive the outcome long before any courtroom is involved.
How a Lawyer Pushes Back on Inflated Fault
This is where experienced representation earns its keep. A good car accident lawyer attacks an inflated fault percentage from several angles:
- Locking down evidence early, before video is erased and witnesses disappear
- Controlling communications, so you never give the adjuster a recorded statement to twist
- Reconstructing the crash, with photos, data, and experts when the stakes justify it
- Knowing the traffic laws, and showing exactly which rules the other driver broke
- Being ready for trial, because insurers assign lower fault percentages to claimants who can credibly take the case to a jury
Shifting your assigned fault from 40% down to 10% does not just feel fairer. As the examples show, it directly changes the check you receive.
How Arizona Compares to Other States
Arizona’s rule is unusually favorable to injured people. The main systems around the country look like this:
- Contributory negligence. In a small handful of states, being even 1% at fault can bar you from recovering anything at all. It is a harsh, all-or-nothing rule.
- Modified comparative negligence. Most states cut you off at a threshold, commonly 50% or 51%. Cross the line and you recover nothing.
- Pure comparative negligence. Arizona’s approach. There is no cutoff. Your recovery is simply reduced by your share of fault, whatever it is.
If you were badly hurt but worry you were mostly to blame, Arizona is one of the states where you may still have a meaningful claim. Do not assume; ask.
Frequently Asked Questions
Can I recover damages in Arizona if the accident was mostly my fault?
Yes. Under A.R.S. § 12-2505, Arizona’s pure comparative negligence rule allows recovery even if you were 99% at fault, though your compensation is reduced by your percentage of fault.
Who decides what percentage of fault I have?
During a claim, the fault percentage is negotiated between you (or your lawyer) and the insurance company based on the evidence. If the case goes to trial, the jury assigns fault percentages.
Will admitting I was speeding ruin my case?
Not necessarily. Speeding may add to your fault percentage, but it does not bar recovery in Arizona. Talk to a lawyer before making any statements, because how facts like this are presented affects the percentage you are assigned.
Does not wearing a seat belt count against me?
It can. Arizona’s adult seat belt law is secondary enforcement, but the failure to wear one can be raised to reduce your damages in some cases.

In a comparative negligence state, your payout depends on a percentage that the insurance company is actively working to inflate. The earlier a skilled attorney starts protecting the evidence and the narrative, the lower that number tends to be.
