Source: Washington Traffic Safety Commission (WTSC), State of the State: Washington Traffic Fatalities – Brief No. 11, October 2025
Traffic fatalities in Washington State have risen sharply in recent years, reaching their highest levels in more than three decades. According to the Washington Traffic Safety Commission (WTSC), 809 people lost their lives in traffic crashes in 2023—the most since 1990—before fatalities declined by 10 percent in 2024. Despite this improvement, several concerning trends remain, including increases in crashes involving teenage drivers, older adults, and distracted driving.
Since 2022, traffic collisions have claimed 2,283 lives and caused 9,807 serious injuries across the state. The reduction in 2024 was most pronounced on county roads (–13.2%) and U.S. highways (–10.6%), while fatal crashes continued to occur most frequently during summer months and weekends. Fridays and Saturdays recorded the highest number of fatal incidents, while the months of September through December—traditionally less hazardous—continued to show unusually high fatality counts.
Key Contributing Factors
Although overall deaths declined, many of the primary causes of fatal crashes remain persistent challenges:
- Impaired driving was involved in 348 deaths in 2024, a 15% decrease from the previous year.
- Speed-related fatalities dropped to 247, while distracted driving deaths rose slightly to 138, continuing a multi-year upward trend.
- Unrestrained occupant deaths fell by 18%, and motorcyclist fatalities decreased by 20%.
- Fatalities among pedestrians and cyclists—referred to as “active transportation users”—remained near record levels, with only a modest 5% decline.
Crashes involving drivers aged 21–25 fell by 30%, while those involving drivers aged 70 and older increased by 17%. Fatalities linked to teen drivers (16–17 years old) rose slightly after a prior decline.
Fatality and Injury Rates
Measured by population, vehicle miles traveled, and vehicle registrations, Washington’s fatality and injury rates climbed through 2023 before stabilizing in 2024.
- The fatality rate per 100 million vehicle miles traveled (VMT) decreased from 1.35 in 2023 to 1.20 in 2024.
- The serious injury rate per 100 million VMT fell from 5.7 to 5.4.
- The fatality rate per 100,000 residents declined from 10.2 to 9.1, reflecting the state’s first measurable improvement in four years.
Despite these gains, long-term rates remain elevated compared to pre-2020 levels, indicating that pandemic-era behavioral shifts—such as speeding and impaired driving—continue to influence roadway safety outcomes.
Disparities by Race and Ethnicity
WTSC data reveal significant racial and ethnic disparities in traffic fatality rates.
- American Indian and Alaska Native residents experience the highest fatality rate per 100,000 population.
- White residents account for over half of all traffic deaths, followed by Hispanic residents (17%).
- Over the past decade, fatalities among Black and Hispanic communities have risen more rapidly than among White residents.
These disparities mirror broader public health trends and highlight the need for culturally informed safety outreach and equitable infrastructure investment.
Regional and County-Level Trends
Fatality trends varied widely across Washington’s 39 counties in 2024. Although statewide numbers improved, nine counties recorded increases in deadly crashes.
- Benton, Lewis, Thurston, and Yakima Counties experienced the steepest year-over-year declines, each exceeding 25%.
- King, Pierce, Snohomish, Spokane, and Yakima Counties together accounted for more than half of all fatal crashes statewide.
These findings underscore the geographic concentration of risk in the state’s most populous and heavily traveled areas.
Pedestrian and Cyclist Fatalities
Crashes involving pedestrians and other “walkers/rollers” remain a growing area of concern, particularly in urban counties.
- King and Pierce Counties together accounted for half of all walker/roller fatalities in 2024.
- Pierce and Clark Counties saw the largest year-over-year increases, while ten counties reported zero pedestrian or cyclist fatalities—the highest number since 2022.
- In total, twenty counties recorded no walker/roller fatalities over the past three years, showing progress in many rural regions even as risks persist in urban environments.
Conclusion
Washington State’s 2024 decline in traffic fatalities marks a hopeful turning point after several years of record-high losses. However, persistent problems—including distracted driving, older driver involvement, and pedestrian safety—illustrate that the road to zero deaths remains long. Addressing these issues will require sustained collaboration between state and local agencies, targeted enforcement, and continued investment in infrastructure and education.
