This bill amends RCW 46.61.506 to enhance the standards and procedures for toxicology testing in Washington State. Key changes include specifying that breath analysis for alcohol concentration will be based on grams per 210 liters of breath, and blood analysis for THC concentration will be based on nanograms per milliliter of whole blood. The bill also clarifies that valid analyses must be performed by individuals with state-approved methods or by laboratories certified under ISO/IEC 17025 standards for forensic toxicology testing. Additionally, it allows out-of-state laboratories to conduct analyses under certain conditions, such as permitting pretrial interviews and virtual appearances of expert witnesses.

Furthermore, the bill introduces a new section to chapter 43.43 RCW, requiring the Washington State Patrol to submit a report by October 1, 2031, to the legislature. This report will provide an update on the backlog of cases awaiting toxicology testing and offer recommendations for addressing any remaining issues. The new section is set to expire on January 1, 2032. Overall, the bill aims to improve the reliability and efficiency of toxicology testing in legal proceedings related to driving under the influence.
