A truck driver involved in last week's fatal pileup inside a road tunnel in Hiroshima Prefecture has admitted to dozing off at the wheel, police said Wednesday.
Narimichi Minami, 33, who was arrested Friday on suspicion of vehicle-related manslaughter, told investigators he was routinely exhausted in his job as a long-distance trucker.
Minami swerved into the adjacent lane after losing control of his vehicle and crashing into cars in front of him, investigative sources said.
