Collision Data for Local Agencies

Cities, counties, tribes, and other organizations often use collision data to identify and prioritize issues and projects. Developing projects that address collisions is also a requirement for certain types of funding.

When a collision occurs on a local public roadway or state highway in Washington, the collision report is sent to the Washington State Patrol for storage. The exception is some roads of tribal jurisdiction. WSDOT's Transportation Data & GIS division partners with Washington State Patrol to code each collision report, except citizen-generated collision reports, into the state's collision database. Local agency transportation professionals then have access to this data to make decisions.

Contact WSDOT's Transportation Crash Data & Reporting Branch to get collision data. Options are:

  • Data sent once, for a project area or for the entire jurisdiction, for a specific time period.
