Washington State Patrol (WSP) provides LCB with data on impaired driving from their Breath Test Program. The LCB uses this information to educate license holders about potential over service. This is particularly helpful when a business has been named as the location of the last drink for multiple arrests of those caught driving above the .08% Blood Alcohol Concentration (BAC) limit.

Between Jan. 1 and Dec. 9, 2024, LCB received over 14,600 DUI reports from WSP’s Breath Test Program. Data show that:

Graph showing the number of last drink reports received in 2024, with an average of 0.15 BAC range — The average BAC was 0.15%. That’s nearly double the legal driving limit of 0.08%!

Pie chart showing gender breakdown, an orange slice representing 76.5% male, a blue slice representing 23.4% female, and 0.10% intersex — The majority were male.

A graph demonstrating the number of last drink reports received in 2024 with the highest amount for the age range of 25 to 29, with 2625 reports — The average was 35 years old.

A pie chart with a blue slice representing 72.6% of reports not involving a collision and an orange slice representing 27.4% involving a collision. — About 27% of cases involved a collision.

Data from 2024 show that on average LCB gets information from about 1,300 DUI arrests using the Breath Test Program every month. Once LCB gets this information, our Enforcement and Education Division works with licensees to make sure that customers showing signs of intoxication, regardless of their BAC level, are not being served alcohol.
