WA HB1426

Creates a new "impaired driving protection order" that can be issued by courts when a respondent poses a significant danger of causing personal injury by driving while under the influence of intoxicating liquor

Allows petitions to be filed by intimate partners, family/household members, law enforcement agencies, prosecuting attorneys, or interested persons who can provide credible testimony about the respondent's DUI history

Court remedies may include requiring ignition interlock devices on all vehicles operated by the respondent, ordering alcohol abstinence, mandating alcohol monitoring devices, compliance with 24/7 sobriety programs, substance use disorder evaluations, and attendance at alcoholism recovery support groups

Establishes criminal penalties: gross misdemeanor for filing false petitions or driving while out of compliance with the order, and class C felony for persons with two or more prior violations of an impaired driving protection order

Requires law enforcement training by July 2026 on impaired driving protection orders, including when officers may conduct motor vehicle stops based on third-party reports of impaired driving
