A man from Licking was seriously injured early Wednesday morning in an accident just north of Waynesville.
Troopers said a southbound 2005 Chevrolet Cobalt driven by Isaac L. Haden, 20, ran off the right side of Highway T and struck a tree at about 1:51 a.m.
Haden was taken by ambulance to Phelps Health in Rolla.
He was wearing a seat belt. The vehicle had extensive damage, the patrol said.
