Alcohol Was a Factor in 334 Arizona Traffic Deaths in 2025 — What ADOT's Data Shows

Alcohol impairment was a factor in 334 Arizona traffic deaths in 2025, down 11.2% from 376 in 2024, according to crash data the Arizona Department of Transportation (ADOT) released August 27, 2026. ADOT says alcohol-related crashes account for 28% of all fatal crashes in the state, which makes impairment one of the three leading factors in Arizona traffic deaths alongside speeding and failure to use a seat belt or helmet.

The drop is real progress, but the underlying pattern in the data has not changed much: impaired-driving crashes still cluster around certain people and certain hours.

Who is involved

ADOT's release says male drivers were involved in 72.9% of alcohol-related crashes. Drivers ages 25 to 34 were the age group most likely to be involved in an alcohol-related crash, accounting for 31.7% of drivers involved in those crashes.

Those figures describe drivers involved in crashes, not every person harmed. Passengers, other motorists, pedestrians and cyclists are also hurt in crashes caused by an impaired driver, and they are not represented in a driver-demographics percentage.

When it happens

In 2025, 2,397 alcohol-related crashes occurred on nights and weekends, which ADOT says accounted for 43.57% of the total alcohol-related crashes. In other words, a little more than four in ten alcohol-related crashes happened in the nights-and-weekends window, even though that window is a minority of the hours in a week. ADOT's release does not break the figure down further by month or by county, so this outlet is not drawing conclusions about specific roads or regions from it.

Where alcohol sits among the leading causes

ADOT's 2025 data identifies speeding, failure to use a seat belt or helmet, and impairment as the leading factors in traffic fatalities, crashes and injuries. The release also notes that at least 8,151 drivers involved in 2025 collisions were engaged in some type of distracted driving behavior, and cautions that this is likely an undercount because drivers may not admit they were distracted or a distracted driver died in the crash.

That caveat matters for impairment as well. A single crash often has several contributing factors, so the categories in the state's data overlap and should not be added together.

What the numbers do and do not show

The 11.2% decline is the type of year-over-year change worth noting, and it fits the broader trend of three consecutive annual declines in total fatalities that we covered in our report on ADOT's 2025 totals. But a decline from 376 to 334 still means hundreds of families affected in a single year.

The data also cannot say why alcohol-related deaths fell. ADOT's release does not attribute the change to a particular law, enforcement campaign or change in behavior, and a one-year move can reflect many things. Readers should be wary of any explanation presented as settled without that evidence.

If you are hurt in a crash involving a suspected impaired driver

Injured people in Arizona typically deal with a mix of police reporting, insurance claims and medical bills, and the deadlines and rules that apply depend on the facts. Practical steps that apply broadly: call 911, ask that police respond and document the scene, seek medical care promptly, and keep records of everything related to the crash.
