On any given morning on Tempe pavement, a student rides an e-scooter or a bicycle across a seam, a patch, or a pothole, and the rider goes down. Concussion. Road rash. A broken wrist on the way to an 8 a.m. class. A face-first fall that sidelines the semester.

What happens next is where the law gets strange. Arizona treats a crash on public pavement differently from a crash between two cars. The clock is shorter. The defendant is a government entity. And if the road happens to sit inside the boundary of Arizona State University, there’s a jurisdictional trap built into the state’s own rules about who can accept a claim.

180 days
The window an injured person has to file a Notice of Claim against a public entity under Arizona Revised Statutes 12-821.01. Miss the deadline and the claim is barred.

What Tempe Says About Its Own Pavement

The City of Tempe runs a Pavement Management Program that measures street condition on a three-year cycle. The city’s page states the policy directly: “The city collects pavement condition data every three years. We use the information to prioritize paving schedules and determine what treatment will be used.”

That’s the cadence. Nothing surprising. What is surprising is what the city writes in its own grant applications.

In the 2026 Maricopa Association of Governments Arterial Road Reconstruction Program application for Broadway Road from 55th Street to Mill Avenue, Tempe Public Works tells MAG that “Tempe’s Pavement Quality Index tracking data shows large portions of the corridor are currently in poor condition (per ASTM classification).” Broadway terminates at Mill Avenue. Mill Avenue runs into the heart of ASU’s Tempe campus. The city is writing, in its own voice, in an official application, that the pavement feeding directly into the ASU area is failing by the engineering standard Tempe itself uses.

Street-by-street Pavement Quality Index scores for Mill Avenue, University Drive, Rural Road, Apache Boulevard, College Avenue, Forest Avenue, and Farmer Avenue weren’t publicly tabulated at the segment level on tempe.gov at the time of this writing. The Pavement Quality Index performance dashboard exists. The segment-level numbers behind it don’t appear to be public. A public records request can pull them.

Tempe also runs Tempe 311, the phone, app, and web intake for non-emergency issues including potholes, sidewalk and curb defects, and debris in the right-of-way. Open tickets, backlog counts, and average repair times for potholes specifically weren’t published on the city’s open data portal at the time of this writing. The 311 caller wait-time dashboard is public. The pothole dashboard isn’t.

None of that changes the law. Tempe’s duty to keep its streets reasonably safe is older than the 311 system. It goes back to the Arizona Supreme Court’s 1951 decision in City of Phoenix v. Weedon. What has changed is the statute of limitations, and what triggers it.

The 180-Day Clock

Arizona Revised Statutes 12-821.01 sets the rule. Here’s the operative language, pulled from the Arizona Legislature’s own site:

Persons who have claims against a public entity, public school or a public employee shall file claims with the person or persons authorized to accept service for the public entity, public school or public employee as set forth in the Arizona rules of civil procedure within one hundred eighty days after the cause of action accrues. The claim shall contain facts sufficient to permit the public entity, public school or public employee to understand the basis on which liability is claimed. The claim shall also contain a specific amount for which the claim can be settled and the facts supporting that amount. Any claim that isn’t filed within one hundred eighty days after the cause of action accrues is barred and no action may be maintained thereon.

Arizona Revised Statutes § 12-821.01 , Notice of Claim Against Public Entity

A private crash between two drivers runs on a different clock. Arizona gives a private personal-injury plaintiff two years under ARS 12-542. The public entity rule is roughly four times shorter.

Most injured people don’t know the difference. A student who goes down on Mill Avenue and assumes they have two years to figure out their legal options is already six months deep on a clock they didn’t know was running. When the 180 days ends, the claim is gone. The statute is unforgiving.

There’s a second clock behind the first. ARS 12-821 gives one year from the date the cause of action accrues to actually file suit against a public entity. The Notice of Claim at 180 days is the gate. The lawsuit at one year is the act. Both have to be right, in sequence, or the case dies.

A separate clock on the public entity side

The statute also deems a claim denied 60 days after filing unless the claimant is notified of the denial earlier. That 60-day deemed-denial rule means the public entity doesn’t have to do anything. Silence becomes denial. The one-year suit-filing clock starts running from that denial, explicit or implied.

The Jurisdictional Patchwork Around ASU

The second thing that catches injured people is that the “public entity” isn’t a single address. Around ASU’s Tempe campus, four different jurisdictions overlap in a one-mile radius:

  • City of Tempe for arterials like Mill Avenue, University Drive (within Tempe), Rural Road, McClintock Drive, College Avenue, Forest Avenue, and Farmer Avenue, and for the right-of-way improvements and pavement that Tempe maintains on those streets.
  • Arizona Department of Transportation for the state system: US-60, Loop 202, the on-ramps, and the frontage roads inside the state right-of-way.
  • Arizona Board of Regents, through ASU for interior campus routes. Tyler Mall, Orange Street, the pedestrian malls, and the internal campus street grid fall under ABOR jurisdiction.
  • Private parking structure owners, private easements, and adjacent development sites that are neither city nor state.

A fall 50 feet east of Mill and University might be a Tempe claim. A fall 50 feet west on the same sidewalk might be an ABOR claim. Each jurisdiction has its own Notice of Claim recipient, and serving the wrong one doesn’t stop the clock.

A verified public jurisdictional overlay of ASU-area streets wasn’t retrievable at the time of this writing. ADOT maintains a pavement portal that shows the state system. Tempe’s own street-maintenance boundaries can be confirmed by public records request. Anyone building a claim needs a jurisdictional map before they file. Guessing doesn’t get you a deemed-denial start date. It gets you a barred claim.

The ABOR Rule That Closes the Trap

Here’s the catch that compounds the 180-day clock. The Arizona Board of Regents publishes its own service-of-process guidance. The guidance states, plainly:

The universities (ASU, NAU or UArizona) aren’t authorized to accept service of lawsuits or notices of claim.

Arizona Board of Regents , Service of Process Policy

Claims must be served on ABOR itself. The Arizona Department of Administration Risk Management manages the state Notice of Claim intake. The delivery address for state-entity claims, including ABOR, is the Arizona Attorney General at 2005 N. Central Avenue, Phoenix, AZ 85004.

This matters because a student who assumes the right way to put the university on notice is to hand a letter to an ASU office is wrong. ASU staff can receive mail. They can forward it. They can’t legally accept service. The Notice of Claim clock keeps running during that forwarding. If the student finds out in month five that the paperwork has to go to the Attorney General, the deadline may already be gone.

Different rules, different recipients

A crash on a Tempe city street sends the Notice of Claim to the City of Tempe.

A crash on an ADOT state highway sends it to the Arizona Department of Administration Risk Management on behalf of the state.

A crash on an ASU-controlled road sends it to the Attorney General on behalf of the Arizona Board of Regents.

A crash at Tempe and ABOR’s shared boundary may require filing with both. Getting the recipient right is part of the statutory requirement.

How Arizona Courts Have Treated Pavement Cases

Two cases tell you how courts apply the law. Both favor the public entity.

In City of Phoenix v. Weedon, 71 Ariz. 259 (1951), the Arizona Supreme Court held that a city has a duty to keep its streets and sidewalks reasonably safe. The plaintiff tripped on a three-quarter-inch sidewalk rise that had existed for years. The Court held the defect was “trivial as a matter of law” and affirmed directed verdict for the city. The case is the doctrinal reason small pavement differentials lose at summary judgment.

Fong v. City of Phoenix, 1 CA-CV 23-0520 (Ariz. Ct. App. Div. 1, 2024), is the recent case that matters for cyclists and scooter riders. The plaintiff rode into an unbarricaded ditch inside an active bike-lane excavation and was injured. The Court of Appeals affirmed summary judgment for both the City and its contractor. The holding: expert testimony is required to establish prima facie negligence for failure to warn, barricade, or monitor an excavation site. Without an expert report on the standard of care in active roadwork, the case doesn’t survive summary judgment.

There’s no Arizona appellate opinion squarely on an e-scooter pavement-defect crash. The Fong 2024 bike-lane ditch case is the nearest analog. What it tells a plaintiff’s lawyer is that a pavement case against a public entity needs an engineer or a traffic-safety professional attached at the outset. A smartphone photograph of a pothole isn’t enough to get past summary judgment.

Combine the two rulings. Small defects lose on Weedon. Larger defects require expert testimony on standard of care under Fong. The public entity defense has a floor and a ceiling.

The Insurance Reality for International Students

Arizona State University requires international F-1 and J-1 students to carry the university-sponsored health insurance plan administered by UnitedHealthcare StudentResources unless they’re sponsored by a waiver-eligible program. The 2025-2026 plan is a Platinum-level plan with an actuarial value of 92.97 percent, a $250 per-person per-year deductible, and $50,000 medical evacuation and $25,000 repatriation benefits. Fall 2025 semester premium was $1,045 for returning students and $1,258 for new incoming.

The plan covers injury, including injury on an e-scooter or a bicycle, under the general injury benefit. What the public summary doesn’t publish is the Certificate of Coverage detail on urgent-care and emergency-room copays. The dollar figures matter. A concussion workup with a CT scan in an Arizona ER runs between $1,000 and $3,000 before insurance. National ER-visit benchmarks land in the $1,500 to $3,000 range without coverage.

The plan year runs August 16 through August 15. A student who graduates in May and has medical follow-ups continuing into summer may lose coverage mid-treatment. The 180-day Notice of Claim clock runs in parallel with whatever the insurance timeline looks like. The two don’t coordinate.

The Policy Window

On December 22, 2025, Tempe formed the Motorized and Electric Mobility Device Safety Council Subcommittee. The stated purpose is to analyze injury and crash data for e-bikes and e-scooters and to draft new regulations. The first meeting was held in January 2026.

Early reporting on the subcommittee’s draft indicates it would allow e-scooters to travel up to 20 miles per hour on nearly all Tempe sidewalks, walkways, and preserve trails. That policy direction runs against the Arizona state-level rule classifying e-scooters as bicycle-adjacent and generally barring them from sidewalks. It also runs against the premise that pavement that can’t safely carry a 15 mph rider is pavement that shouldn’t carry a 20 mph rider under any geometry.

The subcommittee roster, meeting agendas, and public-comment opportunities are posted on the Tempe subcommittees page. The policy window is open. Which means, for anyone writing about the pavement problem, the next six months are the last chance to shape what rules Tempe writes for micromobility on streets the city itself admits are in poor condition.

What to Do If You’re Hurt

Seven practical steps in the first two weeks after a crash on or near ASU:

  1. Get medical care and keep every record. Photocopy or photograph every bill, every imaging report, every discharge note. Head injuries can worsen over days. Document everything.
  2. Photograph the crash site. The pavement defect, the direction of travel, the sight lines, the lane width, any signage or lack of signage. Take wide shots and close-ups. Include a phone or a coin in close-ups for scale.
  3. Get witness contact information. Names, phone numbers, and a one-line account of what they saw. Memory fades fast. Get it on the same day.
  4. File a police report. Tempe Police, ASU Police, or state troopers depending on jurisdiction. Request a copy as soon as the report is available.
  5. Don’t give a recorded statement to any insurer. Anything recorded can be used to narrow a case later.
  6. Note the date of the crash. The 180-day Notice of Claim clock runs from the date the cause of action accrues. The discovery rule in ARS 12-821.01(B) can sometimes extend accrual if the injury wasn’t reasonably knowable, but it’s not a reliable fallback.
  7. Call a lawyer. An attorney can identify the correct public entity, pull Tempe or ADOT records, retain the expert required under Fong, and prepare the Notice of Claim with the specific settlement amount the statute requires.

For a claim involving an ASU-controlled road, the paperwork goes to the Arizona Attorney General on behalf of the Arizona Board of Regents. Not to ASU. Not to the dean of students. Not to the ASU Police Department.

For a claim involving Tempe pavement, the paperwork goes to the City of Tempe City Clerk’s office.

For a claim involving a state highway like US-60 or Loop 202, the paperwork goes to the Arizona Department of Administration Risk Management.

If the crash site straddles a boundary, a claim may need to go to more than one entity. The cost of over-filing is a few stamps. The cost of under-filing is losing the case.

The Bigger Point

Tempe admits in its own grant applications that pavement feeding into ASU is in poor condition. Arizona law gives an injured student 180 days to do something about it. The Arizona Board of Regents publicly forecloses the easiest place a student would think to file. Arizona case law makes the merits harder to win without an expert attached at the outset. The university’s health plan covers the injury, but the window of coverage ends in August of the graduating year. Every one of those elements is public record. None of them is designed to work together.

The students riding e-scooters and bicycles across Tempe pavement every morning are, for the most part, young, transient, often international, and usually the first to ride across a pothole that shows up between three-year Pavement Management Program surveys. They don’t know the 180-day rule. They don’t know ASU can’t accept service. They don’t know that photographing a pothole isn’t the same as surviving summary judgment.

The city is drafting new e-scooter rules this year. The rules will almost certainly loosen sidewalk restrictions before they raise pavement standards. The law will stay the same. The clock will stay the same.

People will keep getting hurt on streets the city has already flagged as failing.

Frequently asked questions

What is the Notice of Claim rule in Arizona, and why does it matter for a scooter or bike crash near ASU?
Arizona Revised Statutes 12-821.01 requires anyone with a claim against a public entity, public school, or public employee to file a written Notice of Claim within 180 days of the cause of action accruing. The claim must include facts supporting liability and a specific settlement amount. If the claim isn't filed in 180 days, it's barred. A separate statute, ARS 12-821, then gives one year from accrual to actually file suit. A crash on Tempe pavement or at an ASU-controlled road involves a public entity. Private crashes between drivers use a two-year personal-injury statute of limitations under ARS 12-542, which is why many injured students don't realize the government clock is running on a separate, much shorter timer.
ASU is part of the Arizona Board of Regents. Why does that matter if I'm hurt on a campus road?
ABOR is the legal governing body for ASU, Northern Arizona University, and the University of Arizona. Arizona Board of Regents' own service-of-process policy states, 'The universities (ASU, NAU or UArizona) aren't authorized to accept service of lawsuits or notices of claim.' Service has to go to ABOR itself, typically through the Arizona Attorney General under the state's Notice of Claim form administered by AZ Department of Administration Risk Management. If a student hands a claim to an ASU office, the clock keeps running, and the filing may not count.
Who is responsible for the road I crashed on?
Jurisdiction around ASU is a patchwork. City of Tempe arterials like Mill Avenue, University Drive, Rural Road, College Avenue, and Apache Boulevard within city limits are maintained by Tempe. State highways like US-60 and Loop 202, including their frontage roads, are Arizona Department of Transportation. ASU interior streets and paths, including Tyler Mall, Orange Street, and pedestrian malls, fall under ABOR. The correct Notice of Claim recipient depends on the exact location of the crash. Getting it wrong can bar the claim.
What has Arizona case law said about pavement-defect claims against cities?
Two cases matter. In City of Phoenix v. Weedon, 71 Ariz. 259 (1951), the Arizona Supreme Court held that municipalities have a duty to keep streets and sidewalks reasonably safe, but that a three-quarter-inch rise in a sidewalk was 'trivial as a matter of law' and supported a directed verdict for the city. In Fong v. City of Phoenix, 1 CA-CV 23-0520 (Ariz. Ct. App. Div. 1, 2024), the Court of Appeals affirmed summary judgment for Phoenix in a bicycle crash into an unbarricaded ditch inside an active bike-lane excavation, holding that expert testimony is required to establish prima facie negligence on failure to warn, barricade, or monitor. The Fong ruling is recent, on point, and adverse to plaintiff cyclists. It raises the evidentiary bar on pavement-and-road-work cases.
Does ASU's international student health insurance cover a scooter or bicycle injury?
Yes, the Arizona State University Student Health Insurance Plan underwritten by UnitedHealthcare StudentResources covers injury on an e-scooter or bicycle as a standard injury. The 2025-2026 plan is a Platinum-level plan with actuarial value of 92.97%, a $250 per-person per-year deductible, and medical evacuation and repatriation benefits of $50,000 and $25,000. Fall 2025 semester premium was $1,045 for returning students and $1,258 for new incoming. The plan runs August 16 through August 15 of the next year, which is why a student who graduates in May can lose coverage before the medical bills settle.
What should I do if I got hurt on an e-scooter or bicycle on or near ASU?
Seven things to do in the first two weeks. (1) Get medical care and keep every bill, imaging report, and discharge note. (2) Photograph the crash location, the pavement condition, and the direction of travel. (3) Get witness names and contact info if possible. (4) File a police report and request a copy. (5) Don't give a recorded statement to any insurer. (6) Note the date of the crash. The 180-day clock runs from that date unless you can argue the cause of action accrued later under the discovery rule in ARS 12-821.01(B). (7) Call a lawyer. The Notice of Claim has to go to the correct public entity, and for an ASU-controlled road that means the Arizona Board of Regents through the Arizona Attorney General, not ASU.
What is Tempe doing about the e-scooter and e-bike safety problem?
On December 22, 2025, Tempe formed the Motorized and Electric Mobility Device Safety Council Subcommittee to analyze injury and crash data and draft new regulations. The first meeting was held in January 2026. Early reporting indicates the draft would allow e-scooters to travel up to 20 miles per hour on nearly all Tempe sidewalks, walkways, and preserve trails. The policy window is open and active. Public comment and member rosters are posted on the Tempe subcommittees page.
What happens if I have an accident with an electric scooter?
What happens after an electric scooter crash in Arizona depends on who was involved and who Arizona law finds at fault. If a car driver’s negligence caused the crash (for example, failing to yield under ARS §28‑771 or violating a traffic signal under ARS §28‑645), that driver’s liability insurance may cover medical bills, lost income, and property damage for people injured. If rider error substantially caused the collision, the rider may be cited under Arizona traffic laws and may have to rely on their own health insurance or potentially their auto or homeowner’s policy, since many e‑scooter riders don’t carry separate scooter coverage. Defective scooters or hazardous road conditions can shift responsibility toward a scooter company, maintenance contractor, or public entity, although claims against government agencies follow strict notice rules under ARS §12‑821.01. As e‑scooter use has grown in cities like Phoenix and Tempe, injury patterns reported in national studies (for example, rising head and brain injuries in e‑scooter riders as of 2024) mirror what Arizona emergency departments are seeing, especially in crashes involving no helmet and night riding.
What is the average personal injury settlement in Arizona?
Arizona sources regularly report broad ranges instead of a single “average” because outcomes vary so much by injury and insurance limits. Several Arizona firms note that many personal injury settlements fall somewhere between about $5,000 and $80,000, with more serious cases commonly exceeding $100,000 and sometimes reaching six or seven figures in cases involving permanent disability or very high medical bills. Recent car accident data suggest typical settlements for minor injuries in the $5,000 to $20,000 range, moderate injuries up to around $70,000 or $100,000, and severe injuries well above that, especially when there is substantial lost income or long-term care. Arizona’s fault-based system and comparative negligence rules (A.R.S. § 12‑2505) allow people injured to seek compensation that reflects their proven medical costs, lost earnings, and non-economic harm, so the “average” in practice depends heavily on those case-specific numbers.
What are the common e-scooter injuries?
Research on standing electric scooters shows head and face injuries are especially common, including concussions, facial fractures, and traumatic brain injuries, often when riders don’t wear helmets (NEISS, IIHS, 2024). Studies report nearly 30 percent of people injured in scooter crashes present with head or neck trauma, and about 8 to 10 percent have major head injuries such as skull fractures or intracranial bleeding. Extremity injuries are also frequent, particularly wrist, arm, ankle, and leg fractures, along with dislocations and soft tissue damage. People injured can also suffer spinal injuries, pelvic or rib fractures, and internal organ trauma, especially in collisions with cars. Arizona treats e-scooters as “electric standup scooters,” and traffic rules that apply to them appear in ARS §28‑101 and related traffic statutes.
Is Arizona a not at fault state?
Arizona uses an at-fault (tort) system for car accidents, not a no-fault system. This means the driver who is found negligent is generally responsible for paying for injuries and property damage through their liability insurance, consistent with Arizona’s minimum coverage rules in ARS § 28-4009 and consumer guidance from the Arizona Department of Insurance and Financial Institutions. People injured can typically pursue a claim against the at-fault driver’s insurer, their own insurer if they bought optional coverages, or a civil lawsuit under Arizona negligence law. Arizona also follows pure comparative negligence (ARS § 12-2505), so each party’s share of fault can reduce but not completely bar their recovery. Arizona does not require personal injury protection (PIP) coverage, which is a hallmark of no-fault states.
