WSDOT Target Zero
WSDOT is guided by the strategies and recommendations in Target Zero, the state’s Strategic Highway Safety Plan. Target Zero’s goal is to reduce the number of deaths and serious injuries on Washington’s roadways to zero by year 2030. WSDOT approaches safety using the Safe System Approach, which places safety as a primary factor in road system investment decisions.
The Safe Systems Approach includes five elements: safe road users, safe vehicles, safe speeds, safe roads, and post-crash care. All five elements must be addressed and strengthened to achieve the Target Zero goal of zero traffic deaths and serious injuries.
