With speeding implicated in 27% of all fatal crashes in the United States in 2022, this post breaks down the patterns behind the numbers from alcohol and seat belts to intersections, rear-end collisions, distraction, and fatigue so you can see exactly what is driving the deaths.

Verified4Insurance claims for vehicle crashes represent billions annually in the US; e.g., 2019 insurers paid $340 billion in auto claims (industry report)[25]
Directional5The cost-effectiveness threshold used in many US evaluations is commonly $100,000–$200,000 per QALY gained (health economics guideline synthesis)[26]
Single source6An enforcement campaign cost per fatality prevented can be below $250,000 in certain scenarios (US safety evaluation study)[27]
Verified7A systematic review found that red light running enforcement interventions can produce benefit-cost ratios ranging from about 2:1 to 10:1 (review)[28]
Verified8A US study estimated that installing speed cameras can yield annual benefits of $1,000 per mile per year in high-risk areas (evaluation)[29]

DirectionalCost Analysis Interpretation
Across these studies, the key trend is that prevention can be highly cost effective, with some interventions preventing a fatality for under $250,000 while benefit cost ratios for red light enforcement range from about 2:1 to 10:1 and workplace driving programs cut crash related costs by 15%.
