Snow Plow Driver Faces DUI Charges He was twice above the legal limit for commercial drivers in West Virginia By Newser Editors and Wire Services Posted Jan 31, 2014 4:16 PM CST 15 comments Comments (Shutterstock) (Newser) – DUI charges are bad enough. DUI charges while driving a state snow plow are liable to make a few headlines. That's the predicament for 56-year-old Thomas Henderson of West Virginia, who got pulled over by a deputy atop a mountain late one night this week, reports WOWK-TV. The deputy stopped the plow because one of its headlights was out, but then he smelled alcohol. Henderson failed a field sobriety test, then blew a .09, which is above the state's regular limit of .08, let alone the stricter limit of .04 for commercial drivers, notes AP.
