Extra officers will be on the roads this weekend looking for impaired drivers.

Tonight begins the annual “Night of 1,000 Stars” DUI emphasis patrols in Snohomish County. Officers, deputies and troopers will meet at the Lynnwood police station for a briefing before they hit the road. The State Patrol’s Mobile Impaired Driving Unit will also be there to speed up the processing of arrested drivers.

Officers will also be on the lookout for speeders, aggressive drivers and people not wearing seat belts.

For the past 20 years, police agencies throughout Washington have conducted “Night of 1,000 Stars” patrols. Each star symbolizes an officer’s badge. This year’s patrol is dedicated to fallen officers, to those that continue to serve, and DUI victims and their families.

“Wintertime driving can be hazardous.  When mixed with alcohol or drugs it becomes deadly,” said Tracy McMillan, Snohomish County DUI & Target Zero Task Force Manager.

McMillan offers these tips to celebrate safely — avoid alcoholic drinks, make plans for a designated driver before going out, arrange to stay overnight, take a cab, and take the keys of impaired friends.
