Is Arizona an At-Fault or No-Fault State?
No — Arizona is an at-fault (tort) state, not a no-fault state.
- Fault system
- At-fault (tort)
The driver responsible for a crash, and their liability insurer, pays for the damage. Arizona has no no-fault or PIP system.
- Comparative negligence rule
- Pure comparative
Your own fault never bars your claim; your damages are reduced in proportion to your share of fault, even if you were mostly to blame. No reduction is available to a claimant who caused the injury intentionally, wilfully or wantonly.
How Arizona compares with every other state
What the fault rule decides
In an at-fault state the driver who caused the crash — through their liability insurer — pays for the harm. That is the arrangement in 38 of the 51 jurisdictions on this site, so it is the one most US advice assumes. The practical consequence is that your recovery depends on two things you do not control: how much liability cover the other driver bought, and what share of the blame you are assigned.
Pure comparative fault has no cliff. Your damages are cut by your share of the blame and nothing more: on a hypothetical $100,000, a driver 80% at fault still recovers $20,000. 9 of the 50 jurisdictions on this site work this way. It is the most forgiving arrangement for a driver who was mostly but not entirely in the wrong, and the reason a claim worth little in a neighboring state can still be worth bringing here.

Why the rule looks like this
- What Changed in 2026Liability minimums doubled in Hawaii, two states dropped pure comparative fault, New Hampshire stopped inspecting cars, and three crash reporting thresholds moved — a dated account of the 2026 changes, and the ones already signed for 2027 and beyond.
- The One Percentage Point That Decides Your ClaimAcross the states covered on this site there are four different rules for what your own share of the blame does to your claim — and in North Carolina, Maryland and Virginia, being 1% at fault ends it entirely.
- No-Fault Does Not Mean Nobody Is at FaultNo-fault restricts the right to sue rather than removing it. Florida, Massachusetts, Michigan and New York run it, New Jersey and Pennsylvania let you choose, and Michigan lets every driver pick one of six PIP ceilings — which changes who pays after a crash.
