Extra police officers will be working again this weekend to look for impaired drivers.

Members of the Snohomish County DUI and Target Zero Team will be patrolling local roads that have a high number of DUI collisions.

Recent DUI campaigns have increased the number of drivers using cabs or designating a sober driver, according to Tracy McMillan, Snohomish County DUI and Target Zero Task Force manager.

“It is clear that our message of ‘Drive Sober or Get Pulled Over’ is working,” she said. “Unfortunately, there are still some drivers who aren’t listening.”

Two deputies recently visited six bars to encourage customers to get a safe ride home and to announce that there were extra DUI emphasis patrols in the area. Despite the warnings, deputies later arrested an impaired driver who said she had been drinking at one of those businesses.

This past Saturday, Washington State Liquor Control Board officers and police agencies cited four establishments in the county for over-service.

“There’s been a lot of attention paid to DUI over the past 25 years, but there hasn’t been the same attention to over-service of alcohol in our businesses,” said Thomas Dixon, enforcement captain for the WSLCB. “The public should know that bars and restaurants that over-serve face serious penalties and eventually revocation of their liquor license.”
