The Washington State Senate has voted 26–23 to approve a bill that would lower the legal blood alcohol concentration (BAC) limit for drivers from 0.08% to 0.05%. The narrow vote, held earlier this week, signals a significant shift in the state’s approach to impaired driving enforcement.

Under the proposed legislation, Washington would join Utah as the only states in the nation with a 0.05% BAC limit. Supporters of the change argue it could save lives by reducing alcohol-related crashes, while opponents say the stricter threshold may do little to improve safety and could harm restaurants and bars that rely on alcohol sales.

Voting largely split along party lines, with most Democrats supporting the bill and most Republicans opposing it. However, 19th Legislative District Senator Jeff Wilson of Longview broke ranks with the majority of his party to vote in favor of the measure. Wilson’s vote could be a reflection of growing bipartisan recognition of local concerns over roadway safety in Southwest Washington, where multiple alcohol-related crashes have made headlines in recent years.

The measure now moves to the state House of Representatives for consideration. If it passes there and is signed by Governor Jay Inslee, the new limit would make Washington one of the strictest states in the country for DUI enforcement.

According to Washington Traffic Safety Commission data, more than half of serious traffic fatalities each year involve impaired drivers. Advocates for the bill say lowering the BAC limit would deter drivers from getting behind the wheel after even one or two drinks, while detractors argue existing penalties and enforcement efforts should be the focus instead of changing the legal threshold.

For Cowlitz County residents, the proposal could have real effects. Law enforcement agencies—including the Cowlitz County Sheriff’s Office and Longview Police Department—would be required to adjust enforcement practices, and local hospitality businesses could face stricter compliance requirements if the measure becomes law.

The House is expected to take up debate on the bill in the coming weeks.
