                Seattle Systemic Speed Limit Reduction, Seattle, Washington Case Study
**Publication Year:** 
            2023
    
        Summary

Speeding, exceeding the posted speed limits, or traveling too fast for conditions was a contributing factor in almost 29 percent of all fatalities in 2021. Of the 42,939 fatalities that occurred on our Nation’s roadways that year, 12,330 were speeding-related—an increase of 7.9 percent from 2020 (Stewart 2023). Speed is fundamental in dictating injury risk for all road users in any crash, especially for vulnerable road users (VRUs) such as pedestrians and bicyclists (Corben 2020).

This is one of ten case studies accompanying the Safe System Approach for Speed Management Report. Read the full report here.
