The S.C. Highway Patrol has found the driver of a pickup truck to have been at fault in a wreck Monday on Interstate 26 that involved a Charleston County sheriff's deputy.

Robert Blankenship, 54, of Spring Meadows Drive in Summerville, is charged with driving too fast for conditions, said Highway Patrol Cpl. Bob Beres.

The wreck took place just before 6 p.m. in the westbound lanes of I-26 near the Aviation Avenue exit, Beres said.

Traffic had slowed due to congestion and the pickup drove into the back of a marked Sheriff's Office cruiser, Beres said. That set off a chain-reaction collision involving two more vehicles, Beres said.

As a precaution, the deputy was taken to a hospital to be checked out, said Maj. Jim Brady of the Sheriff's Office. He was not injured.

No other injuries were reported, Beres said.
