Arizona Right of Way Laws and Intersection Accident Liability Explained

Every year, thousands of crashes happen at Arizona intersections, and most of them come down to one question: who had the right of way? If you've been hit at an intersection, or if you're trying to understand who was at fault, Arizona's right of way laws directly affect whether you can recover compensation and how much. Getting this wrong can cost you thousands of dollars or leave you paying for an accident that wasn't your fault.

What Does "Right of Way" Actually Mean Under Arizona Law?

Arizona's right of way rules are outlined in ARS Title 28, Chapter 7. These statutes define who must yield and who can proceed at intersections, crosswalks, driveways, and other traffic situations. Right of way doesn't give anyone an automatic right to go it establishes a legal obligation to yield under specific conditions. When a driver ignores that obligation and a crash happens, that violation becomes a key piece of evidence in determining fault.

Arizona follows a system where traffic control devices, signage, and statutory rules all work together. If there's a traffic signal, the signal controls. If there's a stop sign, the sign controls. If there's neither, default right of way rules apply. Understanding which layer applies to your situation matters for figuring out who's liable.

Who Has the Right of Way at a Four-Way Stop in Arizona?

This is one of the most common areas of confusion. At a four-way stop:

First to arrive, first to go. The vehicle that reaches the intersection first has the right of way.
Same-time rule. If two vehicles arrive at the same time, the driver on the left must yield to the driver on the right.
Opposing directions. If two vehicles arrive at the same time from opposite directions and one is turning left, the left-turning vehicle must yield to the vehicle going straight or turning right.

These rules seem straightforward, but disputes often arise when two drivers claim they arrived first. Police reports, witness statements, and traffic camera footage can help establish the sequence.

What Happens If a Driver Runs a Red Light and Causes an Intersection Crash?

Running a red light is one of the clearest right of way violations in Arizona. The driver who enters the intersection after the light turns red has violated ARS 28-645, which governs traffic signals. This violation typically places fault squarely on that driver.

However, fault isn't always 100% on one driver. Arizona uses a pure comparative negligence system under ARS 12-2505. This means that even if you were partially at fault say, you were speeding or distracted you can still recover damages, but your compensation is reduced by your percentage of fault. You can learn more about how fault is determined in Arizona intersection car accidents and how it affects your claim.

Do Left-Turning Drivers Always Bear Fault in Arizona?

Arizona law requires left-turning drivers to yield to oncoming traffic that is close enough to pose an immediate hazard. This rule under ARS 28-772 applies at intersections, private roads, and driveways. Because of this obligation, left-turning drivers are often found at fault in intersection collisions.

But "often" doesn't mean "always." Situations where the left-turning driver may not be fully at fault include:

The oncoming vehicle was speeding excessively
The oncoming vehicle ran a red light
The oncoming driver was distracted and could have avoided the crash
Visibility was blocked by a third vehicle or road obstruction

In these cases, fault may be shared. An experienced attorney can investigate the specific circumstances of a left-turn intersection accident to determine whether comparative negligence applies.

How Is Fault Proven in an Arizona Intersection Accident?

Fault in intersection crashes is built from multiple sources of evidence:

Police report. Officers document their findings, issue citations, and note contributing factors. While a police report alone doesn't determine legal fault, it carries weight with insurance companies.
Traffic camera or surveillance footage. Many Arizona intersections have red light cameras or nearby business security cameras. Footage can show signal status, vehicle positions, and speed.
Witness statements. Independent witnesses who saw the crash can corroborate or contradict each driver's account.
Vehicle damage patterns. The location and severity of damage can support claims about direction of travel, speed, and angle of impact.
Accident reconstruction. In serious injury cases, expert reconstructionists analyze physical evidence to determine what happened.

Gathering this evidence quickly matters. Traffic camera footage is often overwritten within days, and witness memories fade. If you're considering a claim, acting fast preserves your options.

What Common Mistakes Do Drivers Make at Arizona Intersections?

Certain patterns show up again and again in intersection crash reports:

Assuming the other driver will stop. Even with a green light, entering an intersection without checking for cross traffic can be dangerous and may affect your liability.
Failing to yield on a yellow light. Many drivers speed up at yellow instead of preparing to stop. If the light turns red before you enter the intersection, you may share fault.
Not stopping at right-on-red. Arizona allows right turns on red after a complete stop, but drivers must still yield to pedestrians and cross traffic.
Misjudging gaps in traffic. Pulling out from a stop sign into insufficient gaps leads to T-bone crashes, which are among the most dangerous intersection collisions.
Distracted driving. Checking a phone, adjusting GPS, or eating while approaching an intersection delays reaction time and often causes drivers to miss signals changing.

What Should You Do Right After an Intersection Accident in Arizona?

The steps you take in the first hours and days after a crash directly affect your ability to recover compensation:

Call 911 and get a police report. Arizona law requires reporting crashes that involve injury, death, or property damage exceeding $2,000. A police report also documents the other driver's information and the officer's observations.
Get medical attention immediately. Some injuries from intersection collisions including whiplash, concussions, and internal bleeding don't show symptoms right away. Early medical records also connect your injuries to the crash.
Document the scene. Take photos of vehicle damage, traffic signals, skid marks, road conditions, and any visible injuries. Note the time of day and weather.
Don't admit fault. Stick to facts when speaking with police and insurance adjusters. Even saying "I'm sorry" can be used against you later.
Notify your insurance company. Report the accident promptly, but avoid giving a recorded statement to the other driver's insurer without legal advice.
Consult a lawyer. If you were injured, an attorney can evaluate your case, handle insurance negotiations, and protect your rights. If you need guidance on choosing representation, here's information on finding the right attorney for an intersection crash injury claim in Phoenix.

Can You Still Recover Compensation If You Were Partially at Fault?

Yes. Arizona's pure comparative negligence law is one of the most plaintiff-friendly systems in the country. Unlike states that bar recovery at 50% or 51% fault, Arizona allows you to recover damages regardless of your fault percentage. Your award is simply reduced by your share of responsibility.

For example, if your damages total $100,000 and you're found 30% at fault, you would recover $70,000. Even if you were 90% at fault, you could still recover $10,000. This system exists because Arizona courts recognize that fault is rarely one-sided in intersection crashes.

What Damages Can You Claim After an Intersection Accident?

If another driver's right of way violation caused your injuries, you may be entitled to:

Medical expenses (past and future)
Lost wages and reduced earning capacity
Pain and suffering
Vehicle repair or replacement costs
Loss of enjoyment of daily activities

The value of your claim depends on injury severity, length of recovery, impact on your ability to work, and the strength of your evidence. Insurance companies often try to minimize payouts, so having documentation of every expense and every way the injury has affected your life strengthens your position.

Quick Checklist After an Arizona Intersection Accident

Get a police report. Always insist on one, even for seemingly minor crashes.
Seek medical care within 24 hours. Delaying treatment gives insurers a reason to question your injuries.
Photograph everything. Intersection layout, vehicle damage, signals, and your injuries.
Identify witnesses. Get names and phone numbers before they leave the scene.
Don't sign anything from the other driver's insurance. Quick settlement offers are almost always low.
Know the statute of limitations. In Arizona, you generally have two years from the date of the accident to file a personal injury lawsuit under ARS 12-542.
Get legal advice early. A free consultation with an attorney costs nothing and helps you understand your rights before making decisions that could affect your claim.
