A tractor-trailer hauling oven cleaner overturned early Saturday after the driver lost control on Interstate 70 just east of Md. 66, according to Maryland State Police.
The driver, Anthony V. Fassett, 37, of Baltimore, was taken to Washington County Hospital, police said.
He was driving east in his truck pulling two semi-trailers when the rear trailer started to sway, causing him to lose control and driving off the right side of the highway, police said.
The truck and trailers overturned, police said.
The Washington County Hazardous Incident Response Team was at the scene until a clean up crew from the Maryland Department of the Environment arrived, police said.
Traffic was not impacted by the accident, police said.
