Understanding Arizona Car Accident Laws: What Every Driver Should Know

July 7, 2026

A car accident can leave you with more questions than answers. Who pays for your medical bills? What if the other driver caused the crash? How long do you have to file a claim? Can you still recover compensation if you were partially at fault?

Arizona law provides answers to these questions, but many accident victims are unfamiliar with how the legal system works until they suddenly need it.

At Skousen, Gulbrandsen & Patience, PLC, we believe that informed clients make better decisions. Understanding Arizona car accident laws can help you avoid costly mistakes and better protect your rights while pursuing compensation after a collision.

Arizona Is an At-Fault State

One of the most important Arizona car accident laws is that Arizona follows an at-fault insurance system.

This means the driver who caused the accident is generally responsible for paying the damages resulting from the collision. Instead of each driver relying solely on their own insurance, an injured victim may pursue compensation from the at-fault driver's liability insurance.

Depending on the circumstances, an injured person may:

  • File a claim with the at-fault driver's insurance company.
  • File a claim under certain provisions of their own insurance policy.
  • File a personal injury lawsuit if a fair settlement cannot be reached.

Determining fault is one of the most important aspects of any car accident claim because it directly affects who may be responsible for paying damages.

Arizona Uses Pure Comparative Negligence

Many people assume they cannot recover compensation if they contributed to the accident. That is not true under Arizona law.

Arizona follows the doctrine of pure comparative negligence. This means an injured person may still recover damages even if they were partially responsible for the collision. Any compensation is reduced by the percentage of fault assigned to that person.

For example, if your damages total $100,000 and you are found to be 20 percent responsible for the accident, you may still recover $80,000.

This legal standard is established under Arizona Revised Statutes § 12-2505, which governs comparative negligence in Arizona.

Understanding how comparative negligence applies often requires a careful investigation of the accident and the available evidence.

How Is Fault Determined?

Insurance companies do not simply accept one driver's version of events. They investigate available evidence before making liability decisions.

Common sources of evidence include:

Police Reports

Responding officers document the accident scene, interview drivers and witnesses, and record important observations that may help establish fault.

Photographs and Video

Pictures of vehicle damage, road conditions, skid marks, traffic signs, and intersections often provide valuable context.

Surveillance footage, dashboard cameras, and nearby security cameras may also capture the collision.

Witness Statements

Independent witnesses can provide objective accounts of how the accident occurred.

Expert Analysis

In more serious cases, accident reconstruction specialists may analyze vehicle damage, roadway evidence, and physics to determine how the collision happened.

No single piece of evidence determines liability. Insurance companies and courts evaluate the totality of the available evidence.

Arizona's Statute of Limitations

Arizona law limits the amount of time you have to file a lawsuit after a car accident.

In most personal injury cases, the statute of limitations is two years from the date of the accident.

Waiting too long can prevent you from recovering compensation, even if your injuries are serious.

Certain situations may involve different deadlines, including:

  • Claims involving government entities
  • Wrongful death claims
  • Claims involving minors

Because deadlines vary depending on the circumstances, it is important to seek legal guidance before assuming you have plenty of time.

The Arizona Legislature publishes the current text of Arizona Revised Statutes § 12-542, which establishes the statute of limitations for most personal injury claims.

Arizona's Minimum Auto Insurance Requirements

Arizona requires drivers to carry minimum liability insurance coverage.

These minimums are designed to provide compensation when an at-fault driver causes injuries or property damage.

The required minimum liability coverage is subject to change through legislation, so drivers should verify current requirements with the Arizona Department of Insurance and Financial Institutions, which maintains up-to-date insurance information for Arizona consumers.

While minimum coverage satisfies legal requirements, it may not fully compensate accident victims who suffer catastrophic injuries or extensive property damage.

What Happens if the Other Driver Has No Insurance?

Unfortunately, not every driver follows Arizona law.

If the at-fault driver is uninsured or carries insufficient coverage, you may still have options.

Many Arizona drivers carry:

  • Uninsured Motorist (UM) coverage
  • Underinsured Motorist (UIM) coverage

These optional coverages can provide compensation when the at-fault driver's insurance is unavailable or inadequate.

Reviewing your own insurance policy after an accident may reveal benefits you did not realize you had.

Why Medical Treatment Matters

Seeking prompt medical care is important for your health and your legal claim.

Some injuries, including concussions, soft tissue injuries, and internal injuries, may not produce immediate symptoms.

Insurance companies often examine medical records closely. Delays in treatment can make it more difficult to demonstrate that your injuries resulted from the accident.

Receiving timely medical attention creates documentation that helps establish both the existence and severity of your injuries.

The Centers for Disease Control and Prevention provides information about recognizing delayed symptoms of traumatic brain injuries and concussions after motor vehicle crashes.

Insurance Companies Protect Their Interests

Many people believe insurance companies automatically work to maximize compensation for injured victims.

In reality, insurance adjusters are responsible for evaluating claims on behalf of their employers.

Before accepting a settlement offer or providing a recorded statement, it is important to understand the full extent of your injuries and financial losses.

Once a settlement agreement is signed, additional compensation is often unavailable, even if your injuries become more serious over time.

When Should You Speak With a Car Accident Attorney?

Not every accident requires legal representation. However, certain situations make experienced legal guidance especially valuable.

Consider consulting an attorney if:

  • You suffered significant injuries.
  • Fault is disputed.
  • Multiple vehicles were involved.
  • The insurance company denied your claim.
  • You received a settlement offer that appears inadequate.
  • The accident involved a commercial vehicle.
  • The at-fault driver was uninsured.

An attorney can investigate the accident, preserve evidence, calculate damages, negotiate with insurance companies, and advocate for your interests throughout the legal process.
