Rural Arizona Roads Are Far Deadlier Per Crash Than Urban Ones, ADOT Data Shows

A crash on a rural Arizona road is far more likely to kill someone than a crash in a city. State crash records for 2024 show that Graham, La Paz, and Apache counties each recorded more than 60 traffic deaths for every 1,000 reported crashes, compared with 6.74 deaths per 1,000 crashes in Maricopa County — roughly a nine- to tenfold gap.

The statewide picture

Arizona logged 121,107 police-reported crashes in 2024, down from 123,256 in 2023. Traffic deaths fell more sharply — from 1,308 in 2023 to 1,228 in 2024, a 6.1% decline — continuing a downward trend the Arizona Department of Transportation (ADOT) has reported for the past several years in its annual Crash Facts report. Total injuries also dipped slightly, from 55,011 to 54,426.

Beneath that statewide improvement, though, the geography of risk is lopsided. According to ADOT's own 2024 Crash Facts report, rural roads carried just 13.05% of the state's crashes but 34.11% of its traffic deaths, while urban roads accounted for 86.95% of crashes but only 65.89% of fatalities.

Where the gap is widest

Ranking Arizona's counties by fatalities per 1,000 crashes in 2024 shows how stark that split gets outside the Phoenix and Tucson metro areas:

• Graham County: 16 deaths in 235 crashes — 68.1 per 1,000
• La Paz County: 29 deaths in 433 crashes — 67.0 per 1,000
• Apache County: 29 deaths in 452 crashes — 64.2 per 1,000
• Navajo County: 35 deaths in 1,192 crashes — 29.4 per 1,000
• Cochise County: 34 deaths in 1,301 crashes — 26.1 per 1,000
• Maricopa County: 594 deaths in 88,094 crashes — 6.7 per 1,000
• Gila County: 8 deaths in 918 crashes — 8.7 per 1,000

Maricopa County still recorded the most crashes and the most total deaths of any county in 2024 by a wide margin, simply because of population and traffic volume — it accounts for roughly 73% of all crashes statewide. But measured by how often a crash turns deadly, it was one of the state's safer places to be in a collision. Rural counties in the northeast and southwest corners of the state, by contrast, saw a crash prove fatal at rates several multiples higher.

Why rural crashes are deadlier

ADOT's data doesn't assign a single cause to this gap, but a few contributing factors are well established in Arizona's own crash reporting and in traffic-safety research more broadly: rural roads tend to carry higher posted speed limits, often lack medians or center barriers that separate opposing traffic, and can leave injured drivers waiting significantly longer for emergency medical help to arrive than a crash in central Phoenix or Tucson would. Two-lane rural highways are also more prone to head-on and run-off-road crashes, which are disproportionately severe compared with the lower-speed intersection crashes that make up a larger share of urban collisions.

Other statewide trends in the 2024 data

Hit-and-run crashes ticked up slightly even as overall crashes fell, rising from 15,779 in 2023 to 16,136 in 2024 — about 13.3% of all crashes last year, per ADOT's report, which recorded 86 deaths and 4,202 injuries in hit-and-run incidents. Alcohol-involved crashes moved in the other direction, dropping from 5,863 in 2023 to 5,520 in 2024, though ADOT's report notes they remained heavily overrepresented in fatal crashes — accounting for just 4.56% of all crashes but 27.93% of fatal ones, with 347 alcohol-related deaths in 2024.

Methodology

Crash and fatality counts above are drawn from ADOT-reported incident records for 2023 and 2024, aggregated by county. Statewide totals and the rural/urban fatality split are cross-checked against ADOT's own 2024 Motor Vehicle Crash Facts report. Fatality figures count all traffic deaths recorded in a given crash, not distinct crash counts, and yearly figures can be revised as ADOT finalizes reporting.
