Two Year Deadline and 180 Day Trap: Arizona Car Accident Laws

Arizona is an at-fault state governed by pure comparative negligence under A.R.S. § 12-2505, meaning you can recover damages even if you share fault, minus your percentage of blame. Drivers must carry 25/50/15 minimum liability coverage, you have two years to sue under A.R.S. § 12-542 (just 180 days if a government entity is involved), and you’re legally required to stop, render aid, and exchange information at the scene. The sections below walk through exactly what each of these rules means for your recovery.

TL;DR:

  • Gathering photographic, video, and witness evidence quickly is crucial within the first few days to prevent loss of key details and records.
  • Insurance coverage should include higher limits than the statutory minimum, especially for serious injuries that could exceed 50,000 dollars in medical costs.
  • Fault is assigned by percentage under Arizona law, making early evidence collection vital to prevent the insurer from shifting blame onto the victim.
  • Filing a claim against a government entity requires strict adherence to a 180-day notice deadline, which must be observed precisely to maintain your right to sue.
  • Hiring an attorney is strongly advisable in complex cases involving disputed fault, commercial vehicles, or government claim deadlines to increase your chances of fair compensation.

What Are Your Duties at the Scene Under Arizona Car Accident Laws?

Arizona law doesn’t leave scene conduct to guesswork. Under A.R.S. § 28-661, any driver involved in a crash causing injury, death, or notable property damage must stop immediately, stay at the scene, and provide reasonable assistance to anyone hurt. That includes calling for medical help if someone needs it. A companion statute, § 28-663, spells out the information exchange: name, address, registration number, and insurance details, handed over to the other driver or a responding officer.

Skipping these duties carries real teeth. Leaving the scene of a crash involving serious injury or death can be charged as a class 2 felony, and even lesser violations can trigger license revocation. Prosecutors don’t need to prove you meant to flee. Failing to stop is often enough.

Call police anytime there’s an injury, a death, or property damage that looks like it exceeds a couple thousand dollars. In most Arizona cities, local police handle the report; on state highways and unincorporated areas, the Department of Public Safety typically responds. Once you’re safe, work through these steps:

  1. Move to safety if the vehicle is drivable and check everyone for injuries.
  2. Call 911 and request police even for a seemingly minor crash.
  3. Photograph vehicle positions, damage, skid marks, traffic signals, and road conditions before anything gets moved or cleared.
  4. Collect names and phone numbers from witnesses before they leave.
  5. Give a brief, factual statement to police. Avoid speculating about fault or apologizing.
  6. Get checked by a medical provider even if you feel fine.

A police report becomes the backbone of most insurance negotiations and lawsuits. It documents the officer’s on-scene observations, citations issued, and often a preliminary fault assessment. You can usually request a copy from the responding agency’s records division a few days after the crash.

Pro Tip: Take a video walk-around of the entire scene, not just still photos. Video captures spatial relationships, traffic flow, and lighting conditions that a handful of photos miss, and it’s much harder for an insurance adjuster to argue you cherry-picked the angle.

How Much Car Insurance Does Arizona Require?

How Much Car Insurance Does Arizona Require? — overview diagram

Arizona requires drivers to carry liability coverage of at least 25/50/15 under A.R.S. § 28-4009: $25,000 per person for bodily injury, $50,000 per accident when multiple people are hurt, and $15,000 for property damage. Those numbers only cover the other party’s losses when you’re at fault. They pay nothing toward your own medical bills or vehicle repairs.

That gap is where Medical Payments coverage (MedPay) and Uninsured/Underinsured Motorist coverage (UM/UIM) come in. MedPay reimburses your own medical costs regardless of fault, and UM/UIM steps in when the at-fault driver either carries no insurance or not enough to cover what you’ve lost. Arizona insurers must offer UM/UIM at the time you buy a policy, and you have to sign a written waiver if you decline it.

  • Liability minimums pay for someone else’s injuries or property damage when you cause a crash.
  • MedPay covers your medical bills up to the policy limit, no fault determination required.
  • UM/UIM protects you when the other driver is uninsured or their coverage runs out before your bills do.
  • Coverage generally follows the vehicle, so an out-of-state driver crashing in Arizona is usually held to their home policy’s limits, not Arizona’s minimums.

A quarter of a million dollars sounds like a lot until you’re staring at an ICU bill. The Arizona Department of Insurance and Financial Institutions is blunt about it: the state’s 25/50/15 floor is often nowhere near enough for a serious injury claim, which is exactly why DIFI pushes drivers toward higher limits and UM/UIM coverage rather than the statutory minimum.

How Does Fault Get Determined in an Arizona Car Accident?

Arizona applies pure comparative negligence under A.R.S. § 12-2505, meaning a jury or insurer assigns a percentage of fault to every party involved, and your recovery shrinks by your own percentage. The catch is that every point of assigned fault costs you real money.

Insurance adjusters know this, and it shapes how they negotiate. A common tactic is nudging fault onto the victim early, before medical records, witness statements, or crash reconstruction data get locked in. That’s why gathering evidence in the first days after a crash matters so much. Once an adjuster’s initial fault narrative sets in, it’s harder to dislodge.

The math is straightforward once you see it applied:

Certain evidence carries outsized weight in how fault gets split. Consider these, roughly in order of influence:

  1. Dashcam or intersection camera footage showing the actual moment of impact.
  2. Police citations issued at the scene, which often reflect an officer’s on-the-spot fault read.
  3. Medical records establishing injury mechanism and timeline.
  4. Witness statements collected before memories fade.
  5. Accident reconstruction analysis for disputed or high-value claims.

What Are the Deadlines for Filing a Car Accident Claim in Arizona?

You generally have two years from the date of the crash to file a personal injury lawsuit in Arizona, per A.R.S. § 12-542. Miss that window and the court will almost certainly dismiss your case, regardless of how strong your evidence is. The clock typically starts on the day of the accident, though a few exceptions apply.

If a government entity, a city vehicle, a county road crew, or a public school bus, contributed to your crash, the timeline compresses dramatically. A.R.S. § 12-821.01 requires a formal notice of claim within 180 days of the incident, filed with the specific public entity involved. This isn’t a formality. Courts treat it as jurisdictional, and missing it usually bars the claim entirely, even though you’d otherwise have two full years.

  • The two-year rule under § 12-542 applies to most private-party personal injury suits.
  • The 180-day notice rule under § 12-821.01 applies specifically to claims against government entities and demands strict procedural compliance.
  • Minors generally get tolling protection, meaning their filing clock may not start until they turn 18.
  • A discovery-rule exception can extend the deadline if an injury wasn’t reasonably discoverable right after the crash.
  • When a public entity might be involved, even peripherally, talk to an attorney well before the 180-day mark, not after.

What Compensation Can You Recover After an Arizona Car Accident?

Arizona law divides recoverable damages into economic and non-economic categories, and importantly, it places no statutory cap on either for personal injury or wrongful death claims. That absence of a ceiling shapes settlement strategy more than most victims realize.

Economic damages cover the costs you can point to a receipt for: medical bills, lost wages, future earning capacity if the injury limits your work, and property damage. Document every one of these as they occur. Non-economic damages compensate for pain and suffering, emotional distress, and loss of enjoyment of life, and their value tends to track injury severity and permanence rather than a fixed formula.

  • Economic damages: medical expenses, rehabilitation costs, lost income, vehicle repair or replacement.
  • Non-economic damages: physical pain, emotional distress, disfigurement, loss of consortium.
  • Wrongful death damages under A.R.S. §§ 12-611 through 613 allow a surviving spouse, children, parents, or a personal representative to sue for the decedent’s family’s losses.
  • No statutory cap exists on compensatory damages, so severe or permanent injuries can support substantial claims when the evidence supports them.

The absence of a damages cap doesn’t mean insurers hand over large settlements voluntarily. It means the ceiling on your recovery is set by your evidence and legal strategy, not by a legislative limit, which is precisely why documentation and timing matter as much as the injury itself.

Do Motorcycle and Commercial Vehicle Crashes Follow Different Rules?

Motorcycle and commercial vehicle crashes layer extra statutes on top of the general framework. Riders under 18 must wear a helmet, and all motorcyclists must use eye protection unless the bike has a windscreen, under A.R.S. § 28-964. Adult riders can legally go helmetless, but insurers often argue that choice contributed to injury severity, an argument that lives or dies on the medical causation evidence, not just the fact that a helmet was absent.

Arizona also permits a narrow form of lane filtering: a motorcycle may pass a stopped vehicle in the same lane at 15 mph or less on roads posted 45 mph or less, under A.R.S. § 28-903. Filter outside those conditions, faster speed, higher-speed road, moving traffic, and you’ve likely handed the other driver’s insurer a fault argument.

  • Riders under 18 must wear a helmet; adult riders may skip one, but expect insurers to raise it as a comparative-fault issue.
  • Legal lane filtering requires stopped traffic, 15 mph or less, and a posted speed limit of 45 mph or less.
  • Commercial trucks and rideshare vehicles often carry policy limits far above the 25/50/15 personal-auto minimum, which can substantially increase what’s available to recover.
  • A rideshare crash’s applicable coverage often depends on whether the driver was logged into the app and carrying a passenger at the time, a detail worth nailing down early.

What Should You Do Immediately After a Crash to Protect Your Claim?

The first 24 to 72 hours after a collision determine how strong your claim will be months later. Evidence disappears, memories fade, and vehicles get repaired or scrapped, so acting fast matters more than most people expect.

  1. Confirm everyone’s safety and call 911, requesting both police and medical response if there’s any possible injury.
  2. Photograph and video the scene from multiple angles before vehicles are moved, including road markings, signal states, and weather conditions.
  3. Collect contact information from every witness present, not just the other driver.
  4. Seek medical evaluation within 24 hours, even for injuries that seem minor. Soft-tissue and concussion symptoms often surface late.
  5. Keep every receipt, from towing to prescriptions to rideshare rides to medical follow-ups, in one folder or file.
  6. Notify your own insurer promptly, but keep statements factual and brief. Don’t speculate about fault or estimate injury severity before you’ve seen a doctor.
  7. Log every call with an adjuster, including the date, the person’s name, and what was discussed or offered.

Medical documentation does double duty. It treats your injury and builds the paper trail an insurer or jury will eventually evaluate. Missed follow-up appointments or gaps in treatment give adjusters an opening to argue your injury wasn’t serious or wasn’t caused by the crash.

An attorney’s early involvement often changes what evidence even exists to preserve. Electronic data recorder (“black box”) information and cellphone location metadata are increasingly decisive in fault disputes, but many systems overwrite that data within weeks. A preservation request or subpoena filed quickly can lock down records that would otherwise vanish before a claim ever gets filed.

Pro Tip: Text yourself a timestamped voice memo describing the crash the same day, while details are fresh. Insurance statements taken weeks later often contradict small details you’d have remembered clearly on day one, and adjusters exploit those inconsistencies.

When Hiring an Attorney Actually Changes the Outcome

Not every fender-bender needs a lawyer. But certain fact patterns consistently produce worse outcomes for victims who go it alone: injuries requiring ongoing treatment, disputed fault where the insurer is pushing blame onto you, an uninsured or underinsured at-fault driver, any crash involving a government vehicle where that 180-day notice clock is running, and collisions with commercial trucks or rideshare vehicles where multiple insurance policies and corporate liability rules come into play.

When Hiring an Attorney Actually Changes the Outcome — overview diagram

Tyler Injury Law built its practice around exactly these harder cases, pairing rigorous case preparation with strategic negotiation rather than accepting an insurer’s first number. That approach produced a $3.25 million settlement in a commercial trucking case, the kind of result that typically requires early evidence preservation, accident reconstruction, and a willingness to litigate rather than settle cheap. Early legal involvement means someone is issuing preservation requests for black-box data, filing any required government notice before the 180-day deadline expires, and negotiating from a position backed by documented evidence instead of a rushed initial statement.

If your crash involves a disputed fault claim, a commercial vehicle, or an insurer that’s already lowballing you, a free case evaluation with Tyler Injury Law is worth the conversation before you sign anything the insurance company sends you.
