A 57-year-old man from Essex was killed Wednesday afternoon when a box truck and Ford F-250 crashed head-on in Fallston, police said.
Southbound Mountain Road was closed just south of Bel Air Road for three hours while police investigated the wreck.
About 4:15 p.m., the 17-year-old driver of the F-250 was traveling north on Mountain Road, approaching Bel Air Road, when police said he crossed the double yellow line. He crashed into the box truck traveling south and driven by Conrad Gilbert, who died at the scene, police said.
The teenager was not named, but police said he was from Baldwin. He was hospitalized; his condition wasn't known.
Police said they don't know what caused the F-250 to cross the line.
