A 47-year-old man died in a single-vehicle crash early this morning about a mile north of Walterboro.

Walter Smith of Walterboro died at the scene from head injuries, Colleton County Coroner Richard Harvey said.

The driver was heading north on Jefferies Highway, which is U.S. Highway 15, about 12:20 a.m. when his 1999 Chevrolet left the road and hit a tree, according to S.C. Highway Patrol Cpl. Bob Beres.

Smith was not wearing a seat belt and was ejected, authorities said.

The factors that contributed to the wreck were not immediately known.
