Disclaimer: 23 U.S.C. 409 - Discovery and admission as evidence of certain reports and surveys and 23 U.S.C. 148 - Highway safety improvement program. Note: 1. *Data is preliminary and subject to change. 2. Crash counts used for 2019 reflects data from the WSDOT Engineering Crash Database. Values for 2020 and 2021 are estimated using preliminary reported crashes and applying the portion non traffic crashes and non-reportable crashes for corresponding months in 2019. The preliminary data used as input reflects the total number of crashes reported regardless of whether it occurred on a public roadway, i.e. it includes, for example, crashes in parking lots, and no apparent injury crashes not meeting damage thresholds per state law. These crashes can represent 10% or more of the total reported crashes and includes crashes from different severity levels. The WSDOT Engineering Crash Database counts do not include the non-traffic crashes and non-reportable crashes. The estimation is required to account for a current backlog in the processing of Police Traffic Collision Reports for the WSDOT Engineering Crash Database. 3. The facility type category reflects the report type. For the collisions that have not been processed/coded by WSDOT, the jurisdiction is based off what the state patrol officer stated and the most severe injury (MSVJ) is generated from the injury types the officer supplied.Back to summary page
