Phoenix is the epicenter for traffic collisions in Arizona, consistently leading the state in total crashes, injuries, and fatalities. The city, which ranks among the top 10 deadliest major U.S. cities for traffic fatalities per capita, sees an average of over 100 accidents daily. Recent data from the Arizona Department of Transportation (ADOT) indicates that while statewide fatalities saw slight decreases in 2023 and 2024, the overall volume of crashes remains a serious concern. In 2024, Phoenix experienced approximately 37,472 total crashes, resulting in 265 fatal crashes and over 10,449 injuries. This makes up roughly one-third of all accidents across the state. The primary contributing factors to these incidents include speeding (a factor in about 34% of deadly crashes), distracted driving, and impairment from alcohol or drugs. Alcohol-related incidents are a particular issue, with Saturday nights between 10 p.m. and 2 a.m. showing the highest rates. Vulnerable road users are disproportionately affected; for example, pedestrians accounted for nearly 250 deaths in the state in 2024, a number driven by driver inattention and a failure to use crosswalks.
