(1) The department shall attach or imprint a notation on the driving record of any person restricted under RCW
46.20.720,
46.61.5055, or
10.05.140 stating that the person may operate only a motor vehicle equipped with a functioning ignition interlock device. The department shall determine the person's eligibility for licensing based upon written verification by a company doing business in the state that it has installed the required device on a vehicle owned or operated by the person seeking reinstatement. If, based upon notification from the interlock provider or otherwise, the department determines that an ignition interlock required under this section is no longer installed or functioning as required, the department shall suspend the person's license or privilege to drive. Whenever the license or driving privilege of any person is suspended or revoked as a result of noncompliance with an ignition interlock requirement, the suspension shall remain in effect until the person provides notice issued by a company doing business in the state that a vehicle owned or operated by the person is equipped with a functioning ignition interlock device.
(2) It is a gross misdemeanor for a person with such a notation on his or her driving record to operate a motor vehicle that is not so equipped, unless the notation resulted from a restriction imposed as a condition of release and the restriction has been released by the court prior to driving. Any time a person is convicted under this section, the court shall immediately notify the department for purposes of RCW
46.20.720(3)(e). It is an affirmative defense, which the defendant must prove by a preponderance of the evidence, that the employer exemption in RCW
46.20.720(6) applies. The court shall not admit evidence of this defense unless the defendant notifies the prosecution prior to the omnibus or pretrial hearing in the case of the defendant's intent to assert the affirmative defense.
