The highest rates of traffic fatalities and injuries in King County occurred in Tukwila, SeaTac, Kent, Renton, Seattle, and Auburn.
Motor vehicle collisions often lead to property damage and personal injury, and sometimes cause death. Victims sometimes include bicyclists and pedestrians. Injuries and deaths from collisions have declined in recent years, in part due to education, mandated use of seat belts, tough impaired-driving laws, and safety engineering.
City data on collision and injury/fatality rates may be useful to municipalities as they implement the new “Neighborhood Safe Streets” law (HB 1045). Rates per 1,000 population can be viewed as descriptors of a community’s traffic environment, with no implications about the residence of those involved in collisions.
- In 2009-2011, King County cities with the highest rates of fatal and non-fatal injuries were Tukwila, SeaTac, Kent, Renton, Seattle, and Auburn. In most of these cities, and in King County overall, the majority of traffic-related deaths and injuries occurred on city streets rather than interstates or state highways.
- For the same years (2009-2011), the cities with the highest numbers of traffic-related fatalities + injuries (regardless of population size) were Seattle, Kent, Bellevue, Renton, Federal Way, and Auburn (data not shown; see Notes & Sources for data table).
- The lowest fatality + injury rates were in Sammamish, Kenmore, Maple Valley, Des Moines, and Mercer Island.
- Kenmore and Redmond had relatively low ratios of injuries + fatalities to collisions (0.25 and 0.35, respectively).
- NOTE: City data on rates of collisions, fatalities, and injuries per vehicle miles traveled (VMT) are not available.
