Arizona Auto Insurance Laws: Complete Producer Guide

Arizona's auto insurance system is one of the cleaner at-fault frameworks in the country — straightforward liability minimums, financial responsibility requirements, and no-fault complexity absent from the equation. But "simpler than Michigan" doesn't mean simple for producers or clients. Arizona's minimum coverage levels are genuinely low and widely criticized for leaving accident victims underprotected. The 2025 ADAS auto glass provision creates new producer disclosure obligations. UM/UIM remains optional but practically essential. And Arizona's at-fault structure means understanding how liability, UM/UIM, and coordination of benefits work together is real advisory value for P&C clients across the state.

Here's what Arizona producers need to know about Arizona auto insurance laws.

Arizona Is an At-Fault State

Arizona operates under an at-fault (tort) liability system — when a driver causes an accident, their liability insurance pays the other party's covered damages. This is the foundational difference from no-fault states like Michigan where each driver's own insurance pays their medical expenses regardless of fault.

In Arizona's at-fault system:

The at-fault driver's liability insurance pays for injuries and property damage they cause to others

The injured party can file a claim with the at-fault driver's insurer

The injured party can sue the at-fault driver for damages

No threshold requirement to access the tort system (unlike Michigan's verbal threshold)

Arizona is a pure tort state: There is no threshold — financial or verbal — limiting an injured party's ability to sue. If you're injured in an Arizona accident and the other driver is at fault, you can pursue a claim directly without meeting any pre-conditions. This is more permissive than Michigan's verbal threshold and Pennsylvania's choice system.

Arizona Auto Insurance Minimums (A.R.S. § 20-266)

Arizona law requires all registered vehicle operators to carry minimum liability insurance:

Bodily Injury Liability:

$25,000 per person — maximum payment for one person's injuries

$50,000 per accident — maximum payment for all injuries in one accident

Property Damage Liability:

$15,000 per accident — maximum payment for property damage caused

Expressed as: 25/50/15

Financial responsibility requirement: Arizona's Financial Responsibility Act requires drivers to maintain proof of this minimum insurance. Failure to maintain required coverage can result in license suspension, registration suspension, and fines.

Electronic proof accepted: Arizona accepts electronic proof of insurance (on a phone or device) during traffic stops and accident reporting.

Monthly payment option (A.R.S. § 20-267): Arizona law provides for motor vehicle liability policies written on a monthly basis — relevant for price-sensitive clients who can't afford annual premiums upfront.

Why Arizona's Minimums Are Widely Considered Insufficient

Arizona's 25/50/15 minimums are among the lower minimum requirements nationally. Practical limitations:

$25,000 bodily injury per person — a single emergency room visit with overnight hospital stay routinely exceeds this limit in Arizona. Catastrophic injuries can produce costs of $500,000 to $2,000,000+.

$50,000 per accident — when multiple people are injured, this splits across all claimants. A family of four in a vehicle can each face the $50,000-per-accident pool.

$15,000 property damage — the average new vehicle price in Arizona now significantly exceeds $15,000. A minimum-limits policy provides no buffer for today's vehicle values.

Producer obligation: Arizona producers serving P&C clients have a genuine advisory responsibility around limits adequacy. Selling minimum-limits policies to clients with significant assets creates both client risk and potential producer liability for failing to discuss higher limits.

Recommended approach: Present higher limit options (100/300/100 or higher for most clients), umbrella coverage for clients with significant assets, and help clients understand what minimum limits actually cover.

Uninsured and Underinsured Motorist Coverage

UM/UIM is NOT mandatory in Arizona. Clients may reject UM/UIM coverage in writing.

Despite this, Arizona's uninsured driver rate is substantial — industry estimates consistently place Arizona among states with higher uninsured motorist rates. This creates real UM/UIM claim risk even for clients who carry adequate liability coverage.

UM (Uninsured Motorist): Pays for your client's damages when the at-fault driver has no insurance.

UIM (Underinsured Motorist): Pays the gap when the at-fault driver's liability limits are insufficient to cover your client's damages.

When UM/UIM must be offered: Arizona requires insurers to offer UM/UIM coverage at least equal to the client's liability limits. Clients can reject it, but rejection must be in writing.

Producer advisory role: Given Arizona's uninsured driver reality, presenting UM/UIM as essential rather than optional protects clients and demonstrates genuine advisory value. Document discussions about UM/UIM in every auto insurance interaction.

Older Driver Rate Reduction (A.R.S. § 20-266.01 / § 20-266 Motor Vehicle Rate Reduction)

Arizona law provides a rate reduction for older drivers who complete qualifying accident prevention courses:

Eligible drivers: Arizona motorists who complete a qualifying accident prevention course (typically 55+ programs like AARP Driver Safety, AAA RoadWise Driver, or similar)

Rate reduction: Insurers must reduce premiums for qualifying completions (specific percentage varies by carrier)

Renewal requirement: Course must be renewed periodically to maintain the premium discount

Producer opportunity: Informing senior clients about this rate reduction — and helping them access qualifying courses — is a genuine value-add in Arizona's active senior market, particularly in Phoenix-area retirement communities.

Arizona's 2025 Auto Claims Update (A.R.S. § 20-269)

Recent Arizona legislation updated motor vehicle insurance claims procedures:

Electronic communications: Arizona auto insurers must now accept electronic communications and submissions for motor vehicle insurance claims.

10-business-day acknowledgment: Insurers must acknowledge receipt of auto insurance claims within 10 business days of notification.

This modernization aligns with how consumers actually interact with insurers — primarily through apps and online portals — and sets clear acknowledgment timelines.

ADAS and Auto Glass (A.R.S. § 20-463.02)

Arizona's 2025 ADAS provision creates specific obligations around auto glass repair and Advanced Driver Assistance Systems:

What ADAS is: Advanced Driver Assistance Systems include lane departure warnings, automatic emergency braking, adaptive cruise control, blind-spot monitoring, and similar technology embedded in modern vehicles — often with sensors located in or near windshields.

The issue: Windshield repair or replacement can displace, obscure, or require recalibration of ADAS sensors. A windshield replaced without proper ADAS recalibration may leave a driver with non-functioning safety systems.

A.R.S. § 20-463.02 requirements:

Insurers must provide required notices to insureds when auto glass repair may affect ADAS

Disclosure obligations when ADAS recalibration may be needed

Civil penalties for violations

Specific definitions

Producer implications: When discussing auto glass coverage with clients — particularly those with newer vehicles — mention ADAS recalibration coverage and ensure their policy addresses this. Document that the discussion occurred.

Arizona Financial Responsibility Law

Beyond mandatory liability minimums, Arizona's Financial Responsibility Act creates an ongoing compliance framework:

SR-22 requirement: After certain violations (accidents without insurance, DUI, serious traffic violations), Arizona may require an SR-22 — a certificate from an insurer verifying the driver maintains minimum liability coverage. The SR-22 must be maintained for the required period (often 3 years).

Non-owner SR-22: For drivers who don't own vehicles but must demonstrate financial responsibility.

SR-22 filing: The insurer files the SR-22 directly with the Arizona Motor Vehicle Division (MVD). The producer's role is ensuring proper SR-22 coverage is in place and filed.

Implications for producers: Understanding SR-22 requirements helps serve clients who need this coverage — often clients who can't find coverage in the standard market and need non-standard auto insurance.

Auto Insurance and Arizona's At-Fault Liability System

How claims flow in Arizona's at-fault system:

Accident occurs — drivers exchange information, report to police if injuries or significant damage

Claim filed — injured party files claim with at-fault driver's liability insurer

Investigation — insurer investigates fault determination

Settlement or litigation — clear liability claims settled; disputed claims may require litigation

Comparative fault in Arizona: Arizona uses pure comparative fault — a plaintiff's recovery is reduced by their percentage of fault, but they can recover even if mostly at fault. This differs from contributory negligence states where any fault bars recovery.

Pure comparative fault example: If a client is 30% at fault for an accident and their damages are $100,000, they can recover $70,000 from the at-fault party. Even a client who is 80% at fault can recover 20% of their damages.

Producer implication: Understanding comparative fault helps explain to clients why UM/UIM and adequate limits matter even in accidents where the client shares some responsibility.

Coordinating Auto Insurance with Health Insurance

Arizona's at-fault system creates important coordination considerations:

Medical payments coverage (MedPay): Optional coverage paying medical expenses for the insured and passengers regardless of fault. Works alongside health insurance — helps cover deductibles and co-pays.

Health insurance coordination: In Arizona's at-fault system, the injured party's health insurance typically pays first, then subrogates against the at-fault driver's liability insurer.

PIP is NOT required in Arizona: Unlike Michigan (mandatory PIP) or other no-fault states, Arizona does not require Personal Injury Protection. The at-fault system means the at-fault driver's liability pays.

Producer implication for senior clients: Senior clients with Medicare as primary health coverage have specific coordination considerations when MedPay and Medicare interact. Understanding these coordination rules adds value in Arizona's active senior market.

5 Frequently Asked Questions

• What are Arizona's auto insurance minimums? 25/50/15: $25,000 bodily injury per person, $50,000 bodily injury per accident, $15,000 property damage per accident. These minimums are among the lower requirements nationally and are widely considered insufficient for modern accident costs.
• Is UM/UIM coverage required in Arizona? No. Uninsured and underinsured motorist coverage can be rejected in writing. However, Arizona's substantial uninsured driver population makes UM/UIM practically essential for most clients.
• How does Arizona's at-fault system differ from no-fault states? In Arizona's at-fault system, the at-fault driver's liability insurance pays the other party's damages. There's no PIP requirement, no threshold to sue, and no limitation on the injured party's right to pursue a claim. Michigan's no-fault system — where each driver's own insurance pays their medical expenses regardless of fault — is fundamentally different.
• What is the ADAS auto glass provision and why does it matter to producers? A.R.S. § 20-463.02 (effective 2025) requires insurers to notify insureds when auto glass repair may affect Advanced Driver Assistance Systems requiring recalibration. Producers should discuss ADAS recalibration coverage with clients who have newer vehicles with windshield-mounted sensors.
• What is pure comparative fault and how does it affect Arizona auto claims? Under Arizona's pure comparative fault rule, a plaintiff's recovery is reduced by their percentage of fault — but they can still recover even if they're mostly at fault. A client 40% at fault can still recover 60% of their damages from the other party.
