DORCHESTER — A driver died at the Dorchester Dragway Sunday night after his truck struck another racer, flipped and hit and concrete pole.

Dorchester County Coroner Chris Nisbet identified the man as 40-year-old Barry Wright. Nisbet said Wright had been racing a black Chevrolet Silverado pickup truck against a Ford Mustang when the Mustang lost control and spun around.

The back end of the Mustang hit the back end of the pickup, causing Wright to lose control and roll over, according to Nisbet. He said the truck pinned Wright against a post.

Nisbet said Wright died of positional asphyxia, meaning he couldn’t breathe.

Dorchester County sheriff’s Maj. John Garrison said the other driver was not injured in the 9:15 p.m. crash.
