Maricopa County has the highest population in Arizona and is the fourth-most populated countrywide. The county highly contributes to the traffic accidents that result in injuries and fatalities yearly in Arizona. The state has seen a slight decline in traffic incidents over the past two years, but crash-related fatalities remain high. In 2023, the state recorded 122,247 motor-vehicle crashes resulting in 1,307 deaths, according to reports by AZDOT. In 2024, total crashes dropped to 121,107 and fatalities fell to 1,228 – a 6.1% decrease from the previous year. Despite this modest improvement, serious injuries and fatalities remain near historically high levels, underscoring persistent road-safety challenges. Speeding, impaired driving, and failure to yield continue to be leading contributors to fatal and serious collisions involving pedestrians statewide. While emergency response initiatives and public-awareness campaigns aim to curb these risks, Arizona's highways and urban roadways still experience a substantial number of severe crashes each year.
