The bill amends existing laws in Washington State concerning driving under the influence (DUI) offenses, specifically targeting the penalties and definitions associated with such offenses. A significant change is the reduction of the threshold for prior offenses from three to two within a 15-year period, which will lead to enhanced penalties for repeat offenders. The legislation maintains the definitions of DUI, including driving with a blood alcohol concentration of 0.08 or higher, and clarifies that prior legal use of drugs does not serve as a defense against DUI charges. It also establishes affirmative defenses that require notification to the prosecution before trial, and outlines specific penalties based on the number of prior offenses and the level of alcohol concentration at the time of the offense.

Additionally, the bill introduces mandatory minimum sentences for individuals convicted of DUI with an alcohol concentration of at least 0.15 or those who refuse a breath test, including 120 days of imprisonment and 150 days of electronic home monitoring. It allows for the conversion of this sentence into a sobriety program if the offender demonstrates a substantial risk to their well-being. The legislation emphasizes the use of ignition interlock devices and alcohol monitoring technologies, while also mandating assessments and treatment for substance use disorders when appropriate. Furthermore, it establishes an effective date of January 1, 2026, and specifies that all fines imposed under this section apply exclusively to adult offenders, thereby enhancing accountability and public safety on the roads.
