The annual “Drive Sober or Get Pulled Over” crackdown on drunk driving started yesterday in Missouri. The crackdown includes high-visibility enforcement throughout Greene County and many others in the Ozarks. It will run through September 2. The Highway Patrol, local police and county sheriffs departments are taking part. The campaign to curb drunk driving will run through Labor Day weekend. Drunk driving takes a particularly heavy toll among young drivers. Among 18- to 34-year-old drivers killed in motor vehicle traffic crashes during the 2011 Labor Day weekend, 42 percent were alcohol-impaired. never drink and drive…always seek a designated driver or call for a ride.
