AN ACT Relating to toxicology testing by certified or accredited laboratories;
Summary
HB 1228 revises Washington’s implied-consent and DUI evidentiary rules governing alcohol and THC testing. The bill specifies when breath and blood test results may be considered evidence in civil or criminal proceedings arising from driving under the influence, and it ties admissibility to testing performed by certified or accredited laboratories or by individuals using methods approved by the state toxicologist. It also sets out technical requirements for breath testing, including observation periods, instrument standards, and the use of approved methods for alcohol and THC analysis.
The bill further updates who may draw blood for alcohol or drug testing and under what conditions. It expands and clarifies the categories of licensed or certified health professionals and forensic phlebotomists who may perform venous blood draws, including when draws occur outside Washington. It also preserves a person’s ability to challenge the reliability or accuracy of the test, while making clear that such challenges go to the weight of the evidence rather than admissibility once the state makes the required foundational showing.
Impact
HB 1228 would amend RCW provisions governing DUI and toxicology evidence, affecting how courts and administrative tribunals evaluate breath and blood test results in impaired-driving cases. It would strengthen the role of the state toxicologist in approving methods, instruments, and permits, and would codify laboratory certification/accreditation requirements for forensic toxicology testing. The bill also affects law enforcement, prosecutors, defense counsel, medical personnel, and testing laboratories by defining admissibility standards, collection procedures, and qualification requirements for those who collect or analyze samples.
Sentiment
The available voting history suggests strong support for the bill in committee, with the House Committee on Community Safety voting 9-0 to substitute the first substitute bill and do pass. No committee transcript was provided, so there is no recorded floor or committee debate to indicate broader public controversy. Overall, the bill appears to have been received as a technical, process-oriented update to impaired-driving evidence rules rather than a highly partisan measure.
Contention
The main points of potential contention are likely to involve evidentiary reliability, laboratory standards, and who is authorized to collect blood samples. The bill’s requirements for certified or accredited laboratories and state-toxicologist-approved methods may be viewed as strengthening scientific rigor, while defense interests may focus on whether the new rules make it easier to admit test results. Another possible issue is the expansion and clarification of who may perform blood draws, which could raise questions among medical professionals, forensic phlebotomists, and defense advocates about training, oversight, and the accuracy of roadside or scene-based collection.
