A father and son hauling dog food in a tractor-trailer were flown to a Baltimore hospital Thursday morning after their truck ran off Interstate 70 south of Hagerstown and plunged down a 60-foot embankment, Maryland State Police said.
The driver of the tractor-trailer, Richard M. McKinney, 57, and his 27-year-old son, William J. Taylor, both of Sharpsville, Pa., were flown by separate helicopters to R Adams Cowley Shock Trauma Medical Center in Baltimore, according to a state police news release.
Troopers said the two men suffered serious injuries in the accident.
A hospital spokeswoman did not immediately return a phone call seeking their conditions Thursday afternoon.
Authorities said the accident was reported at 8:43 a.m.
An investigation determined that the 2005 Freightliner owned by Global Logistics, LLC, of Mercer, Pa., drifted off I-70 East and struck a concrete bridge abutment, police said.
The vehicle then struck a guardrail, crossed the Exit 29 (Md. 65/Sharpsburg Pike) off-ramp, drove through more guardrail and rolled down the embankment.
