Speeding and Reckless Driving: Excessive speed remains one of the primary causes of fatal accidents. The higher the speed, the less time a driver has to react, and the more severe the resulting impact.

Impaired Driving (DUI): Despite aggressive enforcement by the Mesa Police Department and Maricopa County Sheriff’s Office, alcohol and drug impairment continue to play a major role in late-night and weekend crashes. The December 13th crash is being investigated for all potential contributing factors, including impairment.

Distracted Driving: The rise of smartphone use has led to a corresponding increase in distracted driving incidents. Even a few seconds of inattention can lead to catastrophic multi-vehicle pileups, especially on busy streets like US 60 or Loop 202.

Pedestrian and Bicycle Vulnerability: Many fatalities involve pedestrians or cyclists. As Mesa grows, the need for safer crosswalks, better lighting, and protected bike lanes becomes increasingly critical to protect vulnerable road users.

Mesa's Commitment to Safer Streets

The City of Mesa is not passive in the face of these statistics. Through its Comprehensive Safety Action Plan, the city is implementing targeted improvements:

Infrastructure Improvements: This includes redesigning dangerous intersections, installing new traffic signals, enhancing street lighting, and creating safer pedestrian crossings to reduce the risk of serious injury collisions.
