A truck driver from Washington state is facing two drunk driving charges, after investigators say 45-year-old Kendall Cozad mowed over a stop sign at Fleet Farm and later blew a .24 on an alcohol breath test – six times the legal limit for commercial drivers in Minnesota.

The state’s drunk driving standard for commercial vehicles is .04

Mankato Police say Kozad left the scene after running over the sign and when an officer tracked down the vehicle described by witnesses, the truck was swerving over both the center and fog lines.

He first claimed he had not been drinking, but later admitted to having four beers in the store parking lot. The criminal complaint also shows that Kozad failed field sobriety tests and refused to take a portable breath test.

Officers say an empty beer can was found in the cab, as was a nearly empty bottle of alcohol.
