The driver of a semi that ran into a house near Sioux Center in January has been convicted of driving under the influence of drugs. The investigation by the Sioux County Sheriff’s office revealed that the driver of the semi, Timothy Hart of Aberdeen, South Dakota was trying to avoid another semi that was turning in front of him. Hart veered to the left and his semi traveled across a farmyard and struck a house. One person was home at the time and was not injured. The investigating deputy took a body fluid sample form Hart, which was sent to the Department of Public Safety Lab in Des Moines. The results of tests indicated the presence of amphetamine and marijuana. Hart was charged and convicted of operating a commercial vehicle while under the influence of drugs. Hart was sentenced to served 180 days in the Sioux county jail. He was fined one-thousand dollars plus court costs and will be on probation for one year.
