A state police helicopter en route to R. Adams Cowley Shock Trauma Center lifted off from a grassy field next to the scene near the intersection of Rohrersville (Md. 67) and Appletown roads shortly before 5 p.m.
The driver of the box truck was taken by ambulance to Meritus Medical Center with nonlife-threatening injuries, Trooper S. Bussard said.
A trooper at the Hagerstown state police barrack said late Friday night that the condition of the man who was airlifted was believed to have improved, and his injuries were no longer life-threatening.
The crash, reported about 3:50 p.m., happened as the driver of the Cadillac was traveling north on Md. 67 and crossed the centerline, colliding head on with the box truck traveling south, Bussard said.
The driver’s side of the Cadillac, which came to rest about 60 feet north of the box truck on the roadway, was sheered back to the passenger’s compartment. The roof had to be cut off by emergency crews to extricate the man.
Metal and plastic debris was strewn all over the blacktop, which smelled of spilt diesel fuel and oil from the vehicles.
Rohrersville Road at Alt. U.S. 40 in Boonsboro was closed for several hours as state police crash reconstructionists, including a trooper trained specifically for commercial vehicle crashes, investigated the accident, authorities said.
