I Was a Passenger in a Car Accident, Who Do I Sue? (Arizona 2026 Guide)

If you were a passenger in a car accident, who do you sue? In Arizona, you can typically pursue a claim against any at-fault driver, whether that is the driver of the vehicle you were riding in, the other driver, or both. Passengers almost never share fault for a collision, which puts you in one of the strongest legal positions of anyone involved in a crash.

TL;DR: Key Takeaways for Injured Arizona Passengers

Passengers can sue one driver, both drivers, or additional parties depending on who caused the crash.
Arizona is an at-fault state, so the negligent party’s liability insurance pays first.
You can file claims against multiple insurance policies at the same time.
Arizona’s statute of limitations gives you two years from the crash date to file a personal-injury lawsuit.
You almost certainly did nothing wrong, which means comparative-fault rules rarely reduce your recovery.
Elmm Law Group offers free consultations and works on contingency, so you pay nothing unless you win.

I Was a Passenger in a Car Accident, Who Do I Sue? Understanding Your Options

Arizona follows a fault-based (also called “tort”) system for car accidents. That means the person or people who caused the crash are responsible for your medical bills, lost wages, pain and suffering, and other damages. As a passenger, you did not control either vehicle, so your job is simply to identify every negligent party and pursue compensation from each one.

Option 1: Sue the Driver of the Car You Were Riding In

Many passengers feel uncomfortable filing a claim against a friend or family member who was driving. That hesitation is understandable, but keep in mind that you are really making a claim against that driver’s auto insurance policy, not their personal bank account. If your driver ran a red light, was speeding, or was distracted, their liability coverage is the first place to look.

Option 2: Sue the Other Driver

If the other driver caused or contributed to the crash, you can file a liability claim directly against them. In a clear-cut rear-end collision or a left-turn accident, the other driver’s insurer is usually the primary target. You do not have to choose: Arizona allows you to pursue claims against both drivers at the same time if both share responsibility.

Option 3: Sue Multiple Parties

Arizona follows a pure comparative fault rule. Each defendant pays only their proportionate share of fault. So if Driver A was 70% at fault and Driver B was 30% at fault, you collect 70% of your damages from Driver A’s insurer and 30% from Driver B’s insurer. There is no minimum threshold, meaning even a driver who is only 10% at fault still owes you 10% of your losses.

Other Potential Defendants to Consider

A government entity: Poorly maintained roads, missing signage, or defective traffic signals can make a city or county partially liable.
A vehicle manufacturer: If a tire blowout or brake failure caused the crash, a product-liability claim against the manufacturer may be appropriate.
An employer: If either driver was working at the time (delivery driver, rideshare driver, commercial trucker), their employer may share liability under the legal doctrine of respondeat superior.
A bar or restaurant: Arizona’s dram shop law allows claims against establishments that over-served a visibly intoxicated driver who then caused a crash.

Which Insurance Policies Cover a Passenger Injury Claim?

As an injured passenger, you may have access to several layers of insurance coverage, sometimes all at once.

Liability Insurance of the At-Fault Driver(s)

Arizona law requires every registered vehicle to carry minimum liability limits of $25,000 per person and $50,000 per accident. You can learn more about Arizona’s financial responsibility requirements at the Arizona MVD Driver Services page. If the at-fault driver’s limits are not enough to cover your losses, additional sources below may fill the gap.

Uninsured and Underinsured Motorist (UM/UIM) Coverage

If the at-fault driver has no insurance, or their policy limits are too low, you may be able to tap the UM/UIM coverage on the policy of the vehicle you were riding in. You may also be able to use your own UM/UIM coverage from your personal auto policy, even though you were not driving your own car.

MedPay Coverage

Medical payments coverage (MedPay) on either vehicle pays your medical bills regardless of fault. It is a fast source of early cash while the liability investigation is ongoing.

Your Own Health Insurance

Your personal health insurance can cover immediate treatment costs. Your attorney will typically handle any reimbursement (subrogation) obligations to your health insurer out of your final settlement.

Steps to Take After a Passenger Injury in Arizona

Get medical attention immediately, even if you feel fine. Adrenaline masks injuries, and documented treatment is critical to your claim.
Gather information at the scene: names, license numbers, insurance cards, and photos of all vehicles involved.
Request the police report. Arizona law requires officers to report crashes involving injury or significant property damage.
Avoid giving recorded statements to any insurance adjuster before speaking with an attorney.
Contact Elmm Law Group for a free case review as soon as possible. Evidence disappears quickly, and Arizona’s two-year statute of limitations starts running on the date of the crash.

According to Arizona Motor Vehicle Crash Facts published by ADOT, tens of thousands of people are injured on Arizona roads every year. Passengers make up a significant portion of those victims, and many never realize how many sources of compensation are available to them.

Frequently Asked Questions

I was a passenger in a car accident, who do I sue if my friend was driving?

You can file a claim against your friend’s auto liability insurance policy. Most people feel uncomfortable with this, but you are not suing your friend personally. You are making a claim against the insurance coverage they are required by Arizona law to carry. If their policy limits are insufficient, you may also have a claim against the other driver or your own UM/UIM coverage.

Can I be found at fault as a passenger?

It is extremely rare. Passengers do not control the vehicle and are almost never assigned comparative fault in Arizona. The only narrow exceptions might involve a passenger who physically grabbed the wheel or distracted the driver in a provable, direct way. In the vast majority of cases, passengers recover 100% of their damages without any reduction.

What if both drivers were at fault?

You can pursue claims against both drivers simultaneously. Arizona’s pure comparative fault system means each driver pays their proportionate share of your damages. You are not required to pick one or the other, and filing against both protects you if one driver is underinsured.

How long do I have to file a lawsuit as an injured passenger in Arizona?

Arizona’s statute of limitations for personal-injury claims is two years from the date of the accident. Missing this deadline almost always means losing your right to sue entirely. If a government entity is involved, notice-of-claim deadlines can be as short as 180 days, so acting quickly is critical.

Do I need my own attorney if I was just a passenger?

Yes, and arguably more so than the drivers involved. You may have claims against multiple insurers, each of whom will try to minimize your payout. Having an attorney from Elmm Law Group in your corner ensures every available policy is identified, every deadline is met, and your full damages, including future medical costs and pain and suffering, are properly valued and pursued.
