Arizona saw a 5% drop in traffic fatalities in 2025 — the third year in a row of declines.

In spite of the downward trend, the 1,156 traffic fatalities in Arizona last year remains near the all-time high record for the state.

And Arizona Department of Transportation spokesperson Kelsey Mo noted many of the deaths on Arizona roads last year were related to driver behavior.

“It should be a reminder for all of us that we can make better decisions behind the wheel,” Mo said. “Even one death is one too many, so choosing not to speed, choosing to wear seatbelts, and choosing to drive alert and not impaired or distracted — those are all simple things drivers can do to help reduce the number of preventable deaths on Arizona roads.”

According to ADOT, speeding was a factor in 367 Arizona traffic fatalities last year, alcohol impairment was a factor in 334 fatalities, and 320 of the fatalities involved motorists not using a seatbelt or helmet.

Mo says one encouraging sign is that the number of traffic deaths involving alcohol fell slightly, from 376 in 2024 to 334 in 2025.

Arizona also saw slight reductions in pedestrian, bicyclist and motorcyclist fatalities in 2025.
