Speeding Was a Factor in 367 Arizona Traffic Deaths in 2025 — What ADOT's Data Shows

By Arizona Injury News Staff

October 6, 2026 — Arizona

Speeding was a factor in 367 traffic deaths and 19,831 injuries on Arizona roads in 2025, according to the Arizona Department of Transportation (ADOT) — 31.8% of all traffic fatalities and 36.3% of all injuries in the state. ADOT released the figures August 27, 2026, as part of its 2025 crash data showing a third straight annual decline in total fatalities.

What ADOT counted

ADOT's release says that "speeding too fast for conditions or exceeding the lawful speed limit" was involved in crashes that led to 367 deaths and 19,831 injuries. The category covers two different behaviors: driving over the posted limit, and driving too fast for the conditions even when under it. The release does not split the 367 deaths between the two.

Statewide, ADOT counted 1,156 traffic fatalities in 2025, a 5.2% decrease from 2024, across 118,052 crashes.

How speeding compares with other leading factors

ADOT's release identifies speeding, alcohol impairment and failure to use a safety device as the leading factors. The 2025 fatality counts it gives are:

  • Speeding: 367 deaths
  • Alcohol impairment: 334 deaths, down 11.2% from 376 in 2024
  • Failure to use a safety device (seat belt or helmet): 320 deaths

Speeding was the largest of the three by deaths. These categories overlap, because one crash can involve more than one factor, so the numbers should not be added together to estimate a total.

"Too fast for conditions" is written into Arizona law

The phrase in ADOT's data reflects how Arizona's statute is written. A.R.S. § 28-701(A) provides: "A person shall not drive a vehicle on a highway at a speed greater than is reasonable and prudent under the circumstances, conditions and actual and potential hazards then existing."

The same statute requires drivers to slow below the maximum speed in specific situations, including when approaching and crossing an intersection, approaching and going around a curve, traveling on a narrow or winding roadway, and when a special hazard exists with respect to pedestrians or other traffic or because of weather or highway conditions. So a driver can be speeding in the legal sense while still under the posted limit.

What the data does not show

ADOT's release does not say which roads, counties or times of day account for the speeding deaths, and it does not explain why the total fell in 2025. This outlet is not drawing conclusions about specific locations from it. The figures also count crashes in which speeding was a factor, not necessarily the only cause.

The injury count deserves attention on its own: 19,831 injuries means speeding was tied to far more people hurt than killed. Those are the cases where injured people deal with medical bills, time off work and insurance claims.

Context

The speeding figures sit alongside the year's broader results, which we covered in our report on ADOT's 2025 totals and, for impairment, in our look at alcohol-related deaths. ADOT Director Jennifer Toth said in the release: "Fewer fatalities on Arizona's roadways is a move in the right direction, but even one death is one too many."

If you are hurt in a crash involving a speeding driver

Call 911, ask that police respond and document the scene, seek medical care promptly, and keep records of everything related to the crash. Deadlines and rules that apply depend on the facts, so consider consulting a licensed Arizona attorney about your situation. This article is news reporting and is not legal advice.
