Washington Revised Code Title 46. Motor Vehicles § 46.87.320. Departmental audits, investigations--Subpoenas

The department may initiate and conduct audits and investigations to establish the existence of any alleged violations of or noncompliance with this chapter or any rules adopted under it.

For the purpose of any audit, investigation, or proceeding under this chapter, the director or any designee of the director may administer oaths and affirmations, subpoena witnesses, compel their attendance, take evidence, and require the production of any books, paper, correspondence, memoranda, agreements, or other documents or records that the department deems relevant or material to the inquiry.

In case of contumacy or refusal to obey a subpoena issued to any person, any court of competent jurisdiction may issue an order requiring that person to appear before the director or the officer designated by the director to produce testimony or other evidence touching the matter under audit, investigation, or in question. Failure to obey an order of the court may be punishable by contempt.
