Pot Now in the Mix for Drive Sober Crackdown

Posted: Updated:

KENNEWICK, Wash. - From now through Labor Day you're going to see more police, sheriff's deputies, and state troopers on the road.

The annual Drive Sober or Get Pulled Over campaign is underway. Law enforcement throughout Washington has added patrols to look for people driving under the influence.

And with marijuana now legal in Washington, officers have been trained to sniff out drivers impaired by pot.

"First we're going to see impairment in their driving, but then we're going to continue to see something odd, out of normal how a driver should act," says Kennewick Police Sergeant Ken Lattin, who is a specially trained drug recognition expert. Lattin says since marijuana became legal he has seen a significant increase in the number of drivers pulled over and subsequently arrested for driving under the influence of cannabis.

Last year during the Labor Day campaign, law enforcement officers arrested 70 people in Benton and Franklin Counties for driving under the influence.
