Injury Claims Against the City or State in Arizona

The 180-Day Deadline Comes Before Everything Else

Most Arizona injury claims give you two years to file a lawsuit. Claims against the government do not. If a city, county, or state entity caused your crash, A.R.S. § 12-821.01 requires a formal notice of claim within 180 days of the injury. Miss that window and your claim is almost always barred, no matter how strong the case.

That is roughly six months, and the clock runs while you are in treatment, out of work, and waiting on the insurance company. Many victims learn about the deadline after it has passed. Nothing about the crash scene tells you a shorter rule applies.

A City of Tempe truck, a police cruiser, a transit bus, or a defective stretch of road can all trigger this rule. If one of them caused your crash, treat the deadline as the first problem to solve. We connect victims with a Tempe car accident attorney who handles government claims. Call (623) 400-8417 today. The consultation is free.

The rule reaches beyond vehicle crashes, too. Any injury claim against a public entity rides the same 180-day rail. This guide focuses on car accidents, where government fleets and government-maintained roads produce steady casework in Tempe.

When a Public Entity Is Responsible for a Crash

Government liability reaches further than most people expect. The City of Tempe operates maintenance fleets, garbage trucks, police vehicles, and parks equipment. Maricopa County runs its own vehicles and roads. The State of Arizona, through ADOT, designs and maintains the freeways that ring Tempe, including Loop 101, Loop 202, US-60, and I-10.

Public transit agencies, school districts, and public universities add more government vehicles to Tempe streets. A claim can arise from a government driver who caused a crash while working. It can also arise from the condition of the road itself, with no government vehicle involved at all.

The common thread is the defendant, not the crash type. Once a public entity or its employee is responsible, the short deadlines in A.R.S. § 12-821.01 and § 12-821 control the case.

Identifying the correct entity is harder than it sounds. A single Tempe intersection can involve city streets, a county line, and a state-maintained ramp within a few hundred feet. Roadwork may be performed by a private contractor under a public contract. Naming the wrong entity wastes time the 180-day clock does not give back.

Crashes Caused by Government Vehicles

Government vehicles share every major Tempe corridor with commuters, students, and pedestrians. Three scenarios come up most often.

City maintenance and utility vehicles

Street sweepers, garbage trucks, water department rigs, and landscaping crews move slowly, stop often, and pull into traffic from work sites. A loaded municipal truck weighs far more than a passenger car, so the physics resemble a truck accident more than a fender bender. Backing maneuvers and wide turns cause many of these collisions. Crews also work at dawn and dusk, when visibility is at its worst.

Police pursuits and emergency responses

Emergency vehicles run red lights and exceed speed limits by design, and bystanders sometimes pay the price. A driver or pedestrian struck during a pursuit may have a claim against the agency involved. These cases face higher legal hurdles than ordinary crashes, and agencies defend them hard. Dispatch records and body camera footage need to be requested early. The 180-day notice requirement applies from day one.

Bus and transit crashes

Buses make wide turns, stop frequently, and operate on tight schedules through dense corridors like Apache Boulevard and Rural Road. Crashes injure other drivers, riders on board, and pedestrians near stops. When a public transit agency operates the vehicle, the government claim rules apply.

Crashes Caused by Road Conditions

A government entity can be liable for a crash even when no government vehicle touched anyone. Public entities must keep their roads reasonably safe, and failures show up in predictable ways.

Defective signals, signs, and lighting

A malfunctioning traffic signal can send two drivers into the same intersection with matching green lights, producing a T-bone crash neither driver could avoid. Missing stop signs, vegetation blocking sight lines, and burned-out street lighting create similar traps. Proving the entity knew or should have known about the defect is the heart of these cases.

Potholes and pavement failures

Summer pavement heat and monsoon flooding break Tempe roads down fast. A pothole that jolts a car can throw a motorcyclist to the ground at speed. Claims turn on how long the hazard existed and whether the responsible entity had notice and time to repair it.

Construction zones

Lane shifts with faded markings, missing advance warning signs, and badly placed barricades cause crashes in work zones across Tempe. Responsibility may be shared between a public entity and a private contractor. That split matters, because the government defendant gets the 180-day rule while the contractor does not.

What a Notice of Claim Must Contain

A notice of claim under A.R.S. § 12-821.01 is not a casual letter. It must state facts sufficient for the entity to understand the basis of its liability. It must also demand a specific dollar amount for which the claim can be settled, supported by facts. It must reach the right official for that entity, not just any government office.

The settlement amount requires judgment. Set it too low and you may cap your own recovery. State a number without factual support and the entity will attack the notice as invalid. Courts have thrown out claims over defective notices, which is why attorneys treat this document as seriously as a lawsuit.

Each responsible entity must receive its own notice, served on the person authorized to accept it. A crash involving a city vehicle at a state-maintained interchange may require notices to both. The statute does not forgive a notice mailed to the wrong office.

Getting it right the first time matters because there is rarely time for a second attempt. A rejected notice near day 180 usually ends the claim.

One Year to Sue, Not Two

The notice of claim is only step one. A.R.S. § 12-821 requires the lawsuit itself to be filed within one year of the injury. Compare that with the two-year deadline under A.R.S. § 12-542 that applies to ordinary Arizona injury claims. A government case compresses the entire timeline by half, with an extra procedural trap at the six-month mark.

Comparative fault still applies in these cases. Under A.R.S. § 12-2505, your recovery is reduced by your percentage of fault but not eliminated. Government defendants push fault arguments aggressively, so evidence gathered early carries extra weight. Our overview of Arizona car accident laws covers how these rules fit together.

The compressed timeline changes how these cases get worked. Investigation, medical documentation, and the settlement demand all move on a schedule an ordinary claim never faces. Arizona places no cap on compensatory damages in injury cases, so the short deadlines are the main structural hurdle, not the value of the claim.

Move This Week, Not This Month

Every other crash guide on this site tells you to act promptly. This one tells you to act now. The 180-day window closes while medical treatment is still underway, and preparing a valid notice of claim takes real investigation time. Waiting even a few weeks hands the government a defense it did not earn.

The encouraging part: attorneys handle government claims every day, and the deadlines are manageable when the case starts early. A lawyer can identify every responsible entity, prepare a notice that survives scrutiny, and preserve road or vehicle evidence before it changes.

Start with the basics. Get medical care, request your Tempe police crash report, and follow our guide on what to do after a car accident in Tempe. Then call (623) 400-8417 between 9 AM and 9 PM, any day of the week. We will connect you with a local attorney who handles claims against public entities, free of charge and with no obligation.
