Arizona Car Accident Settlements: No Bar, No Free Ride

Arizona has no fault bar at all, but if one defendant cannot pay their share, you generally cannot collect it from anyone else.

Arizona has one of the most claimant-friendly fault rules in the country and one of the least claimant-friendly collection rules — and the two facts don’t cancel out. Understanding both matters more here than in almost any other state.

Quick answer: Arizona uses pure comparative negligence — there is no fault bar at all, and you can recover even if you were mostly at fault, just reduced by your own percentage. But Arizona also abolished joint and several liability for most claims (A.R.S. §§ 12-2506–12-2509): each defendant pays only their own share of fault, not the whole judgment, with narrow exceptions for defendants acting in concert on an intentional tort or in an agency/vicarious liability relationship. The filing deadline is 2 years (A.R.S. § 12-542). Minimum insurance is 25/50/15 (A.R.S. § 28-4009).

Pure Comparative Negligence: No Bar at All

Arizona applies pure comparative negligence, one of the most claimant-favorable fault rules used anywhere in the country. Your recovery is reduced by your own percentage of fault, but there is no cutoff point — you can recover even if you were found 99% at fault, just for the remaining 1%. This sits at the opposite end of the spectrum from pure contributory negligence states like Alabama, Virginia, North Carolina and Maryland, where any fault on your part at all can eliminate your recovery entirely, and it’s more generous than the modified comparative negligence systems most other states use, which cut off recovery once your fault crosses 50% or 51%.

The Catch: Several Liability, Not Joint and Several

This is the detail that makes Arizona genuinely different from most comparative-negligence states, not just another version of the same rule. Under A.R.S. §§ 12-2506 through 12-2509, Arizona abolished joint and several liability for most personal injury, property damage and wrongful death claims. Each defendant is liable only for their own percentage share of the total damages — not the full judgment — so if one of two at-fault defendants is uninsured, judgment-proof, or otherwise unable to pay, you generally cannot shift their share onto the other, solvent defendant.

This runs in the opposite direction from states that deliberately preserve joint and several liability specifically to protect claimants from exactly this scenario. Our guide to California car accident settlements covers California’s hybrid approach under Proposition 51: economic damages remain jointly and severally liable among defendants there, while only non-economic damages are apportioned by fault share — a structure built to prevent an insolvent co-defendant from becoming the claimant’s problem, which is precisely what Arizona’s rule does not do. Arizona isn’t alone in the several-only camp, either — see our guides to Tennessee and Washington car accident settlements for states that adopted the same basic structure through differently-worded statutes, each with its own distinct exceptions; Washington’s even flips to joint and several liability in the specific case where the claimant is found completely free of fault, a mechanism Arizona’s statute doesn’t include. Wisconsin takes yet another approach, tying joint and several liability to each individual defendant’s own fault percentage crossing 51% rather than to a fixed exception or the claimant’s fault status.

Three Narrow Exceptions

A defendant can still be on the hook for more than their own share in three situations under A.R.S. § 12-2506:

  1. Acting in concert. Where defendants entered a conscious agreement to pursue a common plan to commit an intentional tort, and actively took part in it. This exception is specifically limited to intentional conduct — it does not apply to ordinary negligence, no matter how severe or reckless.
  2. Agency or vicarious liability. Where one defendant was acting as an agent or servant of another — the standard scenario where an employer can be held liable for an employee’s fault within the scope of employment.
  3. Federal Employers’ Liability Act duty. A narrow federal exception relevant mainly to railway workers, rarely applicable to an ordinary car accident claim.

What This Looks Like in Practice

Say a jury allocates 70% fault to Driver A and 30% fault to Driver B in a crash that injured you. If Driver A carries no insurance and has no meaningful assets, you generally cannot collect that 70% from Driver B — Driver B’s exposure is capped at their own 30% share, absent one of the three exceptions above. This is why identifying every available source of recovery matters more in Arizona than in most states, and why your own underinsured motorist (UM/UIM) coverage functions as a practical backstop rather than an afterthought. Not every several-liability state leaves the claimant to absorb that gap: see our guide to Connecticut car accident settlements for a statutory mechanism that lets a court reallocate an uncollectible share among the remaining defendants — the fix Arizona’s statute does not provide.

Illustrative Arizona Settlement Ranges

Presentation Illustrative range
Soft tissue injury, conservative treatment $10,000 – $40,000
Herniated disc, conservative treatment $35,000 – $115,000
Surgery performed $150,000 – $475,000
Permanent significant impairment $300,000 – $950,000+
Wrongful death $1,000,000+

These ranges assume full collectability. Where multiple defendants share fault and one cannot pay, the realistic recovery can fall well short of the range above — a distinctly Arizona problem given the several-liability rule described here.

Arizona’s Minimum Insurance Requirements

Arizona requires 25/50/15 under A.R.S. § 28-4009: $25,000 per person and $50,000 per accident for bodily injury liability, plus $15,000 for property damage. These figures have not changed for 2026.

Deadlines in Arizona

ClaimDeadline
Personal injury lawsuit2 years from the accident (A.R.S. § 12-542)
Wrongful deathGenerally 2 years from the date of death
Claims against a government entityA notice of claim generally must be filed within 180 days — far shorter than the general period

Practical Checklist for an Arizona Crash

  1. Identify every potentially liable party, since your recovery from each one is capped at their individual fault share regardless of the others’ ability to pay.
  2. Confirm every defendant’s insurance status early — an uninsured or underinsured co-defendant is a real collection risk here, not just an inconvenience.
  3. Check your own UM/UIM coverage limits before you need them, given how directly Arizona’s several-liability rule can leave a gap for you to fill.
  4. Document the scene thoroughly — photographs, witness statements, dashcam footage, a complete police report — since precise fault percentages determine actual collectability, not just who wins.
  5. Flag any government defendant immediately — the 180-day notice period is far shorter than the general two-year deadline.
  6. Calculate your two-year deadline and diary it now.

Frequently Asked Questions

Does Arizona bar recovery if I was partly at fault?

No. Arizona uses pure comparative negligence, one of the most claimant-favorable fault rules in the country. Your recovery is reduced by your percentage of fault, but there is no cutoff — you can recover even if you were 99% at fault, just for the remaining 1%. This is a categorically different rule from the modified comparative negligence systems most states use, which cut off recovery entirely once your fault crosses 50% or 51%, and it's the opposite extreme from pure contributory negligence states like Alabama, Virginia, North Carolina and Maryland, where any fault at all can bar recovery completely.

If Arizona is this generous on fault, what's the catch?

How you actually collect from multiple defendants. Arizona abolished joint and several liability for most claims under A.R.S. §§ 12-2506 through 12-2509. Each defendant is liable only for their own percentage share of fault — not the whole judgment — so if one of two at-fault drivers is uninsured or otherwise can't pay, you generally cannot shift their share onto the other, solvent defendant. This is the opposite structure from a state like California, which keeps economic damages jointly and severally liable specifically so a claimant isn't left absorbing an insolvent defendant's share.

Are there any exceptions where a defendant does owe the full amount?

Yes, three narrow ones under A.R.S. § 12-2506. First, where defendants were 'acting in concert' — a conscious agreement to pursue a common plan to commit an intentional tort, which specifically does not apply to ordinary negligence, however severe. Second, where one defendant was acting as an agent or servant of another, the standard vicarious liability scenario — an employer can be jointly liable for an employee's fault within the scope of employment. Third, a narrow federal exception under the Federal Employers' Liability Act, relevant mainly to railway workers rather than ordinary car accidents.

How does this play out in an actual multi-vehicle accident?

Say you're injured in a crash involving two other drivers, and a jury allocates 70% of the fault to Driver A and 30% to Driver B. If Driver A has no insurance and no meaningful assets, you generally cannot collect that 70% from Driver B instead — Driver B's exposure is capped at their own 30% share, absent one of the narrow exceptions above. This makes identifying every available source of recovery, including your own underinsured motorist coverage, more important in Arizona than in a joint-and-several state.

How long do I have to file a car accident lawsuit in Arizona?

Two years from the date of the accident under A.R.S. § 12-542. Arizona courts recognize a discovery rule in limited circumstances — most commonly medical malpractice — where the clock starts when the injury was discovered or reasonably should have been discovered, but for an ordinary car accident the two-year period generally runs from the date of the crash itself.

What are Arizona's minimum auto insurance requirements?

25/50/15 under A.R.S. § 28-4009 — $25,000 per person and $50,000 per accident for bodily injury liability, and $15,000 for property damage. These minimums have not changed for 2026.

Since I can't rely on other defendants covering an insolvent one, what actually protects me?

Your own uninsured/underinsured motorist (UM/UIM) coverage, more so than in most states. Because Arizona's several-liability rule leaves you exposed to exactly the scenario where a co-defendant can't pay their share, UM/UIM coverage is the practical backstop rather than an afterthought. Confirm your own policy's limits before you need them, not after.

What evidence matters most in an Arizona claim with multiple potential defendants?

Everything that helps establish each defendant's individual percentage of fault precisely, since your actual recovery from each one turns on that allocation directly rather than on the total judgment. Photographs, independent witness statements, dashcam footage and a complete police report all matter for the usual reasons — but here they also directly determine how much of your damages you can realistically collect, not just whether you win.
