A Rolla man was seriously injured Wednesday morning in a crash on Highway MM five miles northwest of Mountain Grove.
Cpl. Travis Brown said a northbound 2016 Peterbilt 365 concrete truck entered a corner too fast for conditions, ran off the left side of the roadway and overturned at about 9:25 a.m.
The unidentified driver, who was wearing a seat belt, was taken by Texas County Memorial Hospital ambulance to Cox South in Springfield.
Assisting at the scene were Tpr. Nathan Poynter and the Mountain Grove Police Department.
