Bill Overview

Analyzed Economic Effects

2 provisions identified: 1 benefits, 0 costs, 1 mixed.

More labs can test impaired-driving evidence

Beginning June 11, 2026, Washington allows another lab option for blood or breath testing in covered impaired-driving cases. Labs must be certified or accredited under ISO/IEC 17025 for forensic toxicology testing. Testing by a person with a valid state toxicologist permit, using approved methods, remains available. The added lab option expires June 30, 2027.

Local testing contracts protect defense access

Beginning June 11, 2026, Washington cities and counties must contract with the accredited lab before sending covered blood or breath evidence. To obtain evidence already held by the state lab, they must also contract with the Washington State Patrol. They must repay packaging, handling, and transportation costs; without that contract, the state lab need not release evidence. Lab contracts must provide free defense interviews requested at least 30 days before trial. If the report is disclosed fewer than 30 days before trial, defendants must request interviews within 10 days after disclosure. Analysts must accept electronic service of legal filings, discovery, and subpoenas. Cities and counties may accept private nongovernmental donations for covered testing, but have no duty to fund the analysis. These provisions expire June 30, 2027.
