A man is behind bars tonight after rolling his delivery truck off an interstate on-ramp.
Police have arrested the 28-year-old man for driving under the influence after he lost control of this truck and flipped it on its side while heading north on interstate 90.
Clay Kartak of the South Dakota Highway Patrol says at 1:20 p.m. Saturday the man was drifting off the road when he quickly turned the wheel to the left and rolled the truck off the on ramp, taking out a sign on his way.
The man suffered minor head injuries and he had been taking prescription drugs.
He has yet to be identified and police arrested him immediately after he was released from the hospital.
The investigation is ongoing.
