Nathaniel Wright Jr., 74, of Portsmouth, Va., was identified yesterday as the man struck and killed while waving away traffic from his broken-down van Thursday night on Interstate 95 in Perryville, state police said.

Wright was standing next to his van, which was disabled in the slow lane, when a 1997 Jeep Cherokee struck the van and a 1991 Chevrolet Blazer hit the Cherokee and the van, Trooper Glen Peterson said.

Police believe that Wright was hit by his van.

Nancy and Sean Scanlon, both 22, of Panama City, Fla., in the Jeep Cherokee, and Michael Shaw, 22, of Great Barrington, Mass., in the Blazer, were treated at Harford Memorial Hospital and released.
