State troopers are investigating a single-car crash that left two people injured this morning in Berkeley County.

William Lee Keller, 17, of Moncks Corner, was driving east on Whitesville Road when his 1995 Dodge pickup ran off the right side of the road at 7:18 a.m. and overturned, according to Cpl. Bob Beres of the S.C. Highway Patrol.

Keller and an unidentified 14-year-old passenger were transported to Trident Medical Center for treatment, Beres said. Neither was wearing a seat belt, he said.

Troopers cited Keller for traveling too fast for conditions, Beres said.
