Washington law enforcement officers — including those from the Redmond Police Department — will join the national Drive Sober or Get Pulled Over campaign aimed at encouraging everyone to get a safe ride, especially if alcohol, prescription or over-the-counter medicine, or other drug use might be causing any impairment.

Extra patrols will run from Aug. 19-Sept. 5. The Algona, Auburn, Bellevue, Black Diamond, Covington, Des Moines, Enumclaw, Federal Way, Issaquah, Kent, Kirkland, Lake Forest Park, Maple Valley, Mercer Island, Newcastle, Normandy Park, Pacific, Redmond, Renton, Sammamish, SeaTac, Seattle, Shoreline, Snoqualmie, and Tukwila police departments, and the Washington State Patrol will be participating in the campaign through the coordination of the King County Target Zero Task Force.

Approximately one-third of drivers in Washington were drug-positive, according to a new study by the National Highway Traffic Safety Administration (NHTSA).

The same study showed that 5 percent of Washington drivers were alcohol-positive with 1 percent exceeding the per se limit of .08 blood alcohol content.

The NHTSA study mirrors the state’s deadly crash data. In 2015, there were 251 impaired drivers involved in deadly crashes. Of these drivers, 20 percent tested positive for alcohol greater than .08 only and another 20 percent tested positive for a single drug. However, nearly 60 percent of these drivers tested positive for multiple drugs, or drugs mixed with alcohol.

These extra patrols are part of Target Zero—striving to end traffic deaths and serious injuries in Washington by 2030.
