Crash claims in Arizona operate under pure comparative fault. Even at high fault percentages, you retain the right to recover — though every additional point of fault attributed to you shrinks the payout proportionally.
How Pure Comparative Fault Shapes Your Crash Claim
Pure comparative fault states, including Arizona, never bar a crash claim based on the claimant's fault percentage. If you are 10 percent at fault, your recovery is reduced by 10 percent. If you are 70 percent at fault, your recovery is reduced by 70 percent. The claim survives at every level — the question is always how much, never whether.
This does not mean fault allocation is unimportant. Each percentage point of fault directly reduces the dollar value of your recovery. In a substantial crash claim, a 15-point difference in fault allocation can shift the recovery significantly. The insurer knows this and will attempt to assign the highest fault percentage the evidence can support.
Reducing Your Fault Share Through Crash Evidence
Fighting fault allocation in a pure comparative state means building an evidence case that the insurer cannot ignore. The insurer's initial fault estimate is designed to maximize their savings — not to reflect the facts accurately. Your task is to present evidence compelling enough to force a lower number.
The most effective crash evidence is objective and contemporaneous. Photographs taken at the scene before cleanup, event data recorder output from the seconds before impact, and unedited surveillance footage carry more weight than statements made days or weeks later. Witness accounts are strongest when recorded promptly with full contact details. A formal spoliation letter preserving the other vehicle's electronic data should be sent immediately — once that data is gone, it cannot be reconstructed.
A worked example with Arizona’s rule applied
Take a crash claim with documented losses like these:
| Medical bills | $21,500 |
| Lost wages | $3,400 |
| Other out-of-pocket costs | $1,150 |
| Pain and suffering (1.5× medical) | $32,250 |
| Gross value before fault | $58,300 |
Now apply Arizona’s pure comparative rule. Say the insurer pins 60% of the fault on you: the claim is reduced by $34,980 to $23,320 — but it survives. Even a driver found 60% at fault still recovers the remaining share here, which is exactly why adjusters in pure-comparative states argue percentages rather than trying to kill the claim outright.
Building the Crash Evidence File in Arizona
The strongest crash claims are built on layered evidence. Witness statements provide context that photographs and data alone cannot — the color of the traffic light, the speed of a lane change, the behavior of a driver moments before impact. Collect contact information from every witness at the scene before they leave.
Surveillance cameras at nearby businesses, traffic monitoring systems, and residential doorbell cameras may have captured the collision from angles no witness observed. This footage is typically overwritten within 48 to 72 hours. Identifying camera locations and requesting footage preservation before the recording cycles out is one of the most time-sensitive tasks after any crash in Arizona. Delay here means permanent evidence loss.

Questions
Arizona questions
Does shared fault destroy my crash claim in Arizona?
No. Arizona follows pure comparative fault, meaning your claim survives at any fault level. Your recovery is reduced by your assigned fault percentage — 30 percent fault means 70 percent of total damages. The dispute is always about the size of your fault share, and evidence is what determines that number.
How is the fault percentage determined in a Arizona crash case?
Fault percentage is built from crash-scene evidence: police reports, photographs, vehicle data recorder output, witness statements, and sometimes expert reconstruction. The insurer proposes a number, but that number is not final. Stronger documentation gives you leverage to challenge the assessment and push the assigned percentage lower.
If I am mostly at fault for a crash in Arizona, can I still recover damages?
Yes. Pure comparative fault allows recovery at any fault percentage. A claimant at 80 percent fault can collect 20 percent of total damages. The insurer will attempt to assign the highest percentage possible, so your crash-scene evidence is the primary tool for limiting that number and increasing your recovery.
