How Insurance Claims Work After an Accident in Arizona

Arizona uses an at-fault (tort) insurance system. The driver who caused the accident is financially responsible for the other party's damages — medical bills, lost wages, vehicle repair, and pain and suffering. This is fundamentally different from no-fault states like Florida, where each driver's own insurance pays up to a threshold regardless of who caused the crash.

As the injured party in Arizona, you have three paths to compensation. First, you can file a third-party claim directly against the at-fault driver's liability insurance. Second, you can file a first-party claim with your own insurer under your collision, medical payments, or uninsured motorist coverage. Third, you can file a personal injury lawsuit in court. Most claims start with the insurance process and escalate to a lawsuit only if settlement negotiations fail or the statute of limitations is approaching.

Arizona's pure comparative fault rule (A.R.S. § 12-2505) applies to insurance claims too. If you are partially at fault, your compensation is reduced by your fault percentage — but unlike states with a 51% bar (Ohio, Indiana, Illinois), you can still recover even if you were mostly at fault. Insurance adjusters know this and will still aggressively argue that you share blame to reduce what they pay, because every percentage point of fault they assign to you reduces their payout dollar for dollar.

Arizona law requires all drivers to carry minimum liability insurance of 25/50/15 under A.R.S. § 28-4009: $25,000 bodily injury per person, $50,000 bodily injury per accident (all persons), and $15,000 property damage per accident. Arizona's property damage minimum ($15,000) is lower than Indiana's ($25,000), which matters when the at-fault driver carries only minimums and your vehicle is totaled.

These minimums are exactly that — minimums. A serious car accident in Phoenix can easily produce medical bills exceeding $25,000 for a single person. If the at-fault driver carries only the minimum $25,000 per person and your medical bills, lost wages, and pain and suffering exceed that, you face a significant gap. This is where your own underinsured motorist (UIM) coverage becomes critical.

Uninsured motorist (UM) and underinsured motorist (UIM) coverage is optional in Arizona under A.R.S. § 20-259.01. Insurers must offer UM/UIM coverage when issuing or renewing a policy, but you can decline it in writing. Medical payments coverage (MedPay) is also optional — it pays your medical expenses regardless of fault and does not require a liability determination before paying out. If you were hit by an uninsured or underinsured driver and you declined UM/UIM coverage, your options for full recovery are limited to suing the at-fault driver personally, and many uninsured drivers have no assets to collect against.

Step 1: At the scene, call 911 if there are injuries, exchange insurance and contact information with all drivers, photograph the damage and the scene from multiple angles, and get names and phone numbers of witnesses. Do not admit fault or apologize — even saying 'I'm sorry' can be used against you later. Arizona law requires you to stop at the scene, exchange information, and render aid if anyone is injured (A.R.S. § 28-661 through § 28-665). Leaving the scene of an accident with injuries is a class 3 misdemeanor or higher.

Step 2: Report the accident. Arizona requires a written report to the Arizona Department of Transportation within 10 days if the accident resulted in injury, death, or property damage over $2,000. Notify your own insurance company promptly — most policies require timely notification. Provide basic facts only: date, time, location, vehicles involved, and the police report number. Do not speculate about fault or the extent of your injuries.

Step 3: File your claim — either a first-party claim with your own insurer or a third-party claim against the at-fault driver's insurer. You will need your insurance details, the other driver's information, the police report, and documentation of your damages. Step 4: The insurance adjuster investigates — reviewing the police report, interviewing witnesses, inspecting vehicle damage, and reviewing your medical records. Step 5: The insurer makes a settlement offer. You can accept, negotiate for more, or reject the offer and pursue legal action. There is no requirement to accept the first offer, and first offers are almost always lower than what the claim is worth.

The insurance adjuster is not your advocate. Their job is to minimize what the company pays on your claim. They are trained professionals who handle hundreds of claims and know exactly how to get you to say things that reduce your compensation. Being polite is fine. Being careless with your words is not.

What to share: your name and contact information, the date and location of the accident, that you were involved in the accident, and that you are receiving medical treatment. Direct the adjuster to your attorney if you have one. What never to say: 'I'm fine' or 'I feel okay' (symptoms may not be fully apparent yet, and soft tissue injuries often worsen over days or weeks), 'I'm sorry' or anything that could be interpreted as admitting fault, speculation about what happened ('I think I might have...'), or anything about pre-existing conditions.

Do not give a recorded statement to the other driver's insurance company. You are under no legal obligation to do so, and a recorded statement gives the adjuster a transcript they can mine for inconsistencies, admissions, and statements taken out of context. If the adjuster presses you for a recorded statement, simply say: 'I decline to give a recorded statement at this time.' If they insist, end the conversation. Nothing good comes from a recorded statement given without legal counsel.

Reject a settlement offer if: you have not yet reached maximum medical improvement (MMI), meaning your condition is still changing and your full medical costs are unknown; the offer does not cover all medical expenses (past and anticipated future treatment); the offer does not account for lost wages and reduced future earning capacity; or the offer does not include fair compensation for pain and suffering. First offers from insurance companies are typically 30-50% of what the claim is actually worth.

An offer may be reasonable if: you have reached MMI and know your total medical costs, the offer covers all economic damages (medical bills, lost wages, property damage) plus fair compensation for non-economic damages, the at-fault driver's policy limits have been reached (meaning no more money is available from that policy), or further litigation costs would exceed the likely additional recovery.

Once you accept a settlement and sign a release, the claim is permanently closed. You cannot go back for more money if your condition worsens, if you need additional surgery, or if you discover new injuries related to the accident. This is why settling before reaching MMI is risky — you may be signing away your right to compensation for treatment you do not yet know you will need. If the insurance company is pressuring you to settle quickly, that urgency is usually a sign the claim is worth more than they are offering.

Arizona's pure comparative negligence rule (A.R.S. § 12-2505) is the most claimant-friendly fault system possible, and it directly affects how insurance claims are valued and negotiated. Under pure comparative negligence, your recovery is reduced by your percentage of fault — but there is no cutoff. Even at 80% fault, you can still recover 20% of your damages. This is dramatically different from states like Ohio, Indiana, and Illinois, where exceeding 50% fault eliminates your recovery entirely.

Insurance adjusters in Arizona know this and will still fight hard to push your fault percentage as high as possible, because every percentage point matters. At 30% fault on a $200,000 claim, you lose $60,000. At 50% fault, you lose $100,000. The adjuster's goal is to inflate your fault percentage to slash the payout. Strong evidence from the scene — photos, witness statements, dashcam footage, and the police report — is your best defense against inflated fault arguments.

Arizona also follows several liability under Proposition 302 (A.R.S. § 12-2506), meaning each defendant generally pays only their proportionate share of fault. In a multi-vehicle accident, if one at-fault driver is uninsured and cannot pay their share, you absorb that loss. This makes UM/UIM coverage even more important in Arizona — it fills the gap when a responsible party cannot pay.

If your accident involved a government vehicle or entity — a Valley Metro bus, a city maintenance truck, a state highway department vehicle — different insurance and liability rules apply under the Arizona Tort Claims Act. You must file a notice of claim within 180 days of the accident under A.R.S. § 12-821.01. The notice must be filed with the office of the entity's attorney or the person designated to accept service. The claim must include specific facts supporting the claim and a specific dollar amount requested.

After filing the notice of claim, the government entity has 60 days to respond. If the claim is denied or the entity does not respond within 60 days, you can file a lawsuit. But the lawsuit must be filed within 1 year of the date the cause of action accrued under A.R.S. § 12-821 — not the standard 2-year deadline for private party claims. This shorter deadline catches many Arizona accident victims off guard.

Government entities in Arizona are not immune from liability for the negligent acts of their employees acting within the scope of employment, but there are exceptions and damage caps that may apply. Do not rely solely on the insurance claims process for government accidents. The 180-day notice deadline is strictly enforced — missing it bars your claim entirely, even if the 1-year lawsuit deadline has not yet expired.

If your insurance company is acting in bad faith — unreasonably delaying your claim, refusing to investigate, denying a valid claim without explanation, or offering unreasonably low settlements — you can file a complaint with the Arizona Department of Insurance and Financial Institutions (DIFI). DIFI is the state regulatory agency that oversees insurance companies operating in Arizona.

To file a complaint, contact your insurance company directly to attempt resolution first. If that fails, file through the DIFI website at difi.az.gov or call (602) 364-3100. Provide copies of all relevant correspondence, your policy number, and a detailed description of the issue. DIFI will review the complaint and contact the insurer for a response.

Arizona also has specific protections under A.R.S. § 20-263: no insurer can increase your motor vehicle insurance premium as a result of an accident that you did not cause or significantly contribute to. If your rates were raised after an accident that was not your fault, file a DIFI complaint and request a premium review.

Arizona's statute of limitations for personal injury claims is 2 years from the date of injury (A.R.S. § 12-542). This is your hard deadline for filing a lawsuit if the insurance claim does not resolve. For property damage, the deadline is also 2 years. For wrongful death, the deadline is 2 years from the date of death (A.R.S. § 12-611). Government tort claim notices must be filed within 180 days (A.R.S. § 12-821.01), with a 1-year lawsuit deadline (A.R.S. § 12-821).

Insurance companies know these deadlines and may use delay tactics to push you closer to the expiration date, reducing your leverage. As the statute of limitations approaches, the insurer knows you have less time to file a lawsuit, which weakens your negotiating position. Starting the claims process early — and consulting an attorney well before any deadline — preserves your leverage and gives you time to build the strongest possible case.
