Maricopa County Fatal Crashes — 4,054 Deaths in 8 Years

Maricopa County is home to over 4.5 million people — and an alarming number of traffic fatalities. Our analysis of the NHTSA Fatality Analysis Reporting System (FARS) reveals 3,801 fatal crashes resulting in 4,054 deaths in Maricopa County between 2015 and 2022. The numbers are getting worse, not better.

The County-by-County Picture

Maricopa County dominates Arizona’s fatal crash statistics, but it’s not the only county with serious problems. Here are the top Arizona counties by fatal crash count (2015–2022):

• Maricopa County — 3,801 fatal crashes, 4,054 deaths
• Pima County — 1,023 fatal crashes, 1,098 deaths
• Pinal County — 416 fatal crashes, 476 deaths
• Mohave County — 312 fatal crashes, 358 deaths
• Yavapai County — 277 fatal crashes, 316 deaths
• Coconino County — 249 fatal crashes, 291 deaths
• Yuma County — 172 fatal crashes, 191 deaths
• Navajo County — 170 fatal crashes, 193 deaths
• Apache County — 125 fatal crashes, 146 deaths
• Cochise County — 120 fatal crashes, 139 deaths

Maricopa County accounts for nearly half of all fatal crashes in Arizona. This reflects both its population concentration and the particular dangers of the Phoenix metro’s road design — wide, high-speed arterials that function like highways but run through urban areas with pedestrians, cyclists, and cross-traffic.

The Trend Is Going the Wrong Direction

Year-over-year fatal crashes in Maricopa County:

From 2015 to 2022, fatal crashes increased by 50% and deaths increased by 49%. The Maricopa County population grew by roughly 12% over the same period — meaning fatalities are growing four times faster than the population.

2020 saw a spike despite reduced driving during COVID — likely due to higher speeds on emptier roads and increased reckless driving. The post-COVID years (2021–2022) locked in the higher fatality rate.

Where the Fatalities Happen

Our data identifies the deadliest corridors:

Highways: I-10 leads with 447 fatal crashes, followed by US-60 (253), I-17 (209), and the Loop 101 and Loop 202 freeways.

Surface streets: Indian School Road (84 fatal crashes), McDowell Road (63), 19th Avenue (56), 43rd Avenue (55), and Broadway Road (53) are the deadliest arterials.

Concentration: The West Phoenix corridor between 43rd and 83rd Avenues accounts for a disproportionate share of surface-street fatalities.

Who Is Dying?

Fatal crashes in Maricopa County involve vehicle occupants (drivers and passengers) in the majority of cases, but pedestrians and motorcyclists are overrepresented relative to their share of road users. Phoenix consistently ranks among the most dangerous major cities in America for pedestrians.

What’s Causing the Increase?

Multiple factors are driving the upward trend: population growth adding more vehicles to already-stressed roads, higher speeds — both posted limits and actual travel speeds, distracted driving from smartphones, more impaired driving — DUI remains a persistent problem, and road design that prioritizes vehicle throughput over safety.

What This Means for You

If you’ve been injured in a Maricopa County car accident, you’re not a statistic — but statistics can help your case. This data demonstrates the foreseeability of crashes on specific roads, at specific times, under specific conditions. When we present your case to an insurance adjuster or jury, this context establishes that the danger was known, predictable, and that a reasonably careful driver should have exercised greater caution.

The Law Badgers built this database because we believe in preparation that goes deeper than anyone else. 3,801 fatal crashes in eight years. 4,054 lives lost. Every one of them left a family behind — and many of those families have legal rights they may not know about.
