A woman died after a tow truck hit a tractor trailer she had been riding in and threw her into a guardrail, Maryland State Police said.
Troopers told The Herald-Mail of Hagerstown that the driver of the tractor-trailer pulled off to the side of the Interstate 70 near the Frederick County line Monday afternoon because it was overheating.
The victim, a co-driver, went outside the rig when a tow truck hit it, knocked the tractor-trailer into her and threw her into the guardrail.
The woman was pronounced dead at Meritus Medical Center. The driver of the tow truck also was taken to Meritus with non-life-threatening injuries.
The crash is under investigation.
