Who Is Liable in an Intersection Collision in Arizona?

Getting hit at an intersection in Arizona is stressful enough. But figuring out who actually caused the crash and who should pay for your medical bills, lost wages, and car repairs can feel like a whole second battle. Arizona follows specific rules when it comes to intersection liability, and understanding those rules can mean the difference between getting fair compensation and walking away with nothing. Whether you were T-boned at a red light or sideswiped by someone running a stop sign, knowing how fault works at Arizona intersections puts you in a stronger position from the start.

How Does Arizona Determine Fault at an Intersection?

Arizona is a fault-based state, which means the driver who caused the collision is responsible for the damages. At intersections, fault usually comes down to right-of-way rules under Arizona traffic law. These rules tell us who should go first and who should yield.

Common situations that establish fault include:

Running a red light or stop sign The driver who ignores the signal or sign is almost always at fault.
Failing to yield the right-of-way Turning left in front of oncoming traffic or pulling into an intersection when it's not safe.
Illegal turns Making a U-turn or right turn where it's prohibited.
Speeding through a yellow light Entering the intersection when the light turns red, even though you had time to stop.

Arizona law also uses a comparative negligence system. That means more than one driver can share fault. If you were found 20% responsible and the other driver was 80% responsible, you can still recover compensation just reduced by your percentage of fault. This rule is outlined in Arizona Revised Statutes §12-2505.

What If Both Drivers Claim They Had the Green Light?

This is one of the most common disputes after an intersection crash. When both drivers insist they had the right-of-way, the case often depends on evidence like:

Traffic camera footage
Witness statements
Vehicle damage patterns (which can show angles of impact)
Police reports and the officer's diagram of the scene
Black box data from the vehicles

Insurance companies will look at all of this to assign fault percentages. If you're dealing with this kind of dispute, working with an attorney who handles intersection crash injury claims in Phoenix can help you gather the right evidence to support your side.

Who Pays for My Injuries After an Intersection Accident?

In Arizona, the at-fault driver's liability insurance should cover your damages. That includes medical expenses, vehicle repair or replacement, lost income, and pain and suffering. Arizona requires all drivers to carry minimum liability insurance of:

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

But here's the catch: those minimums often don't cover serious injuries. If your damages exceed the other driver's policy limits, you may need to file a claim under your own uninsured/underinsured motorist coverage or pursue the at-fault driver personally.

What About Crashes Involving City Vehicles or Government Drivers?

If a city bus, police car, or other government vehicle caused the intersection collision, different rules apply. Arizona's notice of claim statute (A.R.S. §12-821.01) requires you to file a formal notice within 180 days of the crash. Miss that deadline, and your claim could be thrown out entirely. These cases move fast and follow strict procedures, so acting quickly matters.

Can a Pedestrian or Cyclist Be Liable in an Intersection Collision?

Yes. While drivers have a general duty to watch for pedestrians and cyclists, the person on foot or bike can share fault if they:

Crossed against a "Don't Walk" signal
Stepped into the road suddenly without giving drivers time to stop
Were riding a bicycle against traffic through the intersection

Arizona's comparative negligence law still applies here. A pedestrian who is 30% at fault can still recover 70% of their damages from the driver.

What Are Common Mistakes People Make After an Intersection Crash?

A lot of people hurt their own claims without realizing it. Here are the biggest mistakes to avoid:

Admitting fault at the scene Even saying "I'm sorry" can be twisted into an admission. Stick to exchanging information and talking to the police.
Not calling the police A police report creates an official record. Without one, it becomes your word against the other driver's.
Waiting too long to see a doctor Gaps in medical treatment make insurance companies argue your injuries weren't serious. Get checked out within 24-48 hours, even if you feel okay.
Giving a recorded statement to the other driver's insurance Their adjuster is not on your side. Anything you say can be used to reduce your payout.
Accepting a quick settlement offer Early offers are almost always far less than what your case is worth, especially before you know the full extent of your injuries.

If you've already made one of these mistakes, don't panic. An experienced attorney can still work to protect your claim. You can learn more about how liability is determined in Arizona intersection crashes and what steps to take next.

How Long Do I Have to File a Claim for an Intersection Collision?

In Arizona, the statute of limitations for personal injury is two years from the date of the crash. For property damage, you also have two years. If someone died in the crash, the family has two years to file a wrongful death claim.

Two years might sound like a long time, but building a strong case takes work getting medical records, accident reconstruction, negotiating with insurers. The sooner you start, the better your chances.

What If the Other Driver Was Uninsured?

Arizona has a significant number of uninsured drivers on the road. If the person who hit you doesn't have insurance, you have a few options:

Uninsured motorist (UM) coverage on your own policy This kicks in when the at-fault driver has no insurance at all.
Underinsured motorist (UIM) coverage This helps when the other driver's policy limits aren't enough to cover your losses.
A personal lawsuit against the at-fault driver This only makes sense if they have assets worth pursuing.

Many people don't realize they carry UM/UIM coverage until they need it. Check your policy or ask your agent.

Do Intersection Crashes Go to Court in Arizona?

Most intersection collision cases settle out of court through insurance negotiations. But sometimes a lawsuit is necessary especially when the insurance company denies fault, offers a lowball amount, or drags the process out. Filing a lawsuit doesn't mean you'll end up in a trial. Many cases settle during the litigation process, often through mediation.

If your injuries are serious and the financial stakes are high, having an attorney who isn't afraid to take the case to court can make a real difference in your settlement offer. You can explore options for pursuing an intersection collision injury lawsuit or settlement depending on the details of your situation.
