DUI Breath Test Laws

WAC 448-16-010
Basis for rules governing breath testing.

In RCW 46.61.506(4), the legislature establishes criteria for the admissibility of breath alcohol test evidence. RCW 46.61.506(3) authorizes and directs the state toxicologist to approve satisfactory techniques or methods, to supervise the examination of individuals to ascertain their qualifications and competence to conduct such analyses, and to issue permits to those individuals. These rules are intended to implement the direction of the statute by 1) approving instruments and associated equipment capable of performing a reliable breath alcohol test, 2) identifying classifications of individuals who are to be examined for their competence to conduct such tests, and operate or maintain that equipment, and 3) identifying certain aspects of the operation of that equipment, necessary for reliable testing.
