Is Arizona a No-Fault State for Car Accidents? Zanes Law

Is Arizona a no-fault state for car accidents? No, it follows an at-fault system, meaning the driver who caused the crash is financially responsible for the other party’s medical bills, lost wages, and property damage. Injured drivers typically file a claim against the at-fault driver’s liability insurance, and fault must be established before compensation is paid.

At Zanes Law, our attorneys have helped car accident victims throughout Phoenix and the surrounding Arizona communities understand their options and pursue the compensation they deserve. This guide explains how the state’s at-fault system works, how fault is divided, and what to do if the other driver is uninsured.

What “At-Fault” Actually Means in Arizona

Arizona is an at-fault state, sometimes called a “tort” state. In simple terms, this means the person who caused the accident is responsible for paying for the injuries and damage they caused. In most cases, their liability insurance covers these costs up to their policy limits.

Unlike no-fault states, Arizona doesn’t require drivers to carry Personal Injury Protection (PIP) insurance. Instead, drivers rely on liability insurance and the fault determination process to recover compensation after a crash. Arizona law also requires drivers to carry minimum liability insurance coverage under A.R.S. § 28-4009.

The Difference Between No-Fault and At-Fault States

In a no-fault state, your own insurance pays for your medical expenses through Personal Injury Protection (PIP) coverage, regardless of who caused the accident. In many of those states, you cannot sue the other driver unless your injuries meet certain legal thresholds.

Arizona works differently. Because it is an at-fault state, injured drivers generally seek compensation from the driver who caused the crash.

Arizona’s Required Car Insurance Coverage

Arizona drivers must carry minimum liability insurance that includes:

$25,000 for bodily injury per person
$50,000 for bodily injury per accident
$15,000 for property damage

These are minimum requirements only. Serious accidents often result in damages that exceed these limits.

Arizona also doesn’t require uninsured or underinsured motorist (UM/UIM) coverage. However, insurance companies must offer it in writing when you purchase a policy. This optional coverage can provide important financial protection if you’re injured by someone who has little or no insurance.

What Arizona’s At-Fault System Means After Your Accident

Knowing Arizona is an at-fault state is only part of the picture. The next question is usually, “What should I do after a crash?” The answer depends on the facts of your accident, but most claims follow a similar process.

Filing a Third-Party Claim Against the At-Fault Driver

After an accident, you’ll usually file a third-party claim with the at-fault driver’s liability insurance company. Their insurer will investigate the accident by reviewing the police report, speaking with witnesses, examining vehicle damage, and determining how much fault each driver shares.

Once the investigation is complete, the insurance company may make a settlement offer. Remember, the other driver’s insurance company works to protect its own financial interests, not yours. Consulting with a Phoenix car accident attorney can help protect your rights and make sure you get the compensation you deserve.

What If the At-Fault Driver Has No Insurance?

Not every Arizona driver carries insurance, even though it’s required by law. If the at-fault driver has no insurance, you may be able to:

File a claim through your own uninsured motorist (UM) coverage if you purchased it.
Use underinsured motorist (UIM) coverage if the driver’s policy limits are too low.
File a lawsuit directly against the at-fault driver, although collecting compensation may be difficult if they have limited assets.

Suing the At-Fault Driver Directly

Arizona law allows injured victims to file a personal injury lawsuit against the at-fault driver when appropriate. Unlike no-fault states, you don’t have to meet a serious injury threshold before filing suit.

In most cases, you have 2 years from the date of the accident to file a personal injury lawsuit under A.R.S. § 12-542. However, if your accident involved a government vehicle or public employee, you may need to file a Notice of Claim within 180 days under A.R.S. § 12-821.01.

How Arizona Divides Fault When Both Drivers Share Blame

Arizona follows a pure comparative fault rule. This means more than one driver can share responsibility for an accident, and your compensation is reduced by your percentage of fault.

This differs from many other states that follow a modified comparative fault system, where drivers lose the right to recover compensation if they are found to be 50% or 51% responsible. In Arizona, you can still recover damages even if you share most of the blame for the crash.

How Insurance Companies Use Comparative Fault Against You

At the end of the day, insurance companies are trying to protect their bottom line. As a result, they will try to reduce your payout as much as possible. One way they do this in Arizona is by inflating your percentage of fault for the accident.

For this reason, avoid admitting fault at the scene or giving a recorded statement to the other driver’s insurance company before understanding your legal rights. It’s also important to preserve evidence by taking photographs, collecting witness information, and obtaining a copy of the police report whenever possible.

Common Mistakes Arizona Drivers Make After an At-Fault Accident

Filing a car accident claim is a delicate process, and one wrong move can significantly affect your compensation. Avoiding these common issues can help protect your rights and your settlement:

Giving a recorded statement too soon. The other driver’s insurance company may use your own words to argue that you were partially responsible for the accident and reduce your settlement.
Accepting the first settlement offer. Early offers often don’t account for future medical treatment, lost income, or the full impact of your injuries. Once you accept a settlement, you generally can’t seek additional compensation later.
Missing important legal deadlines. Most personal injury lawsuits must be filed within 2 years, while claims involving government entities have much shorter notice requirements.
Declining uninsured motorist coverage. Because Arizona doesn’t require UM/UIM coverage, some drivers choose not to purchase it. If you don’t purchase it and then get hit by an uninsured driver, your recovery options may be much more limited.
