A 61-year-old man was killed when he was knocked off his motorcycle in Fremont by the rear axle of a big-rig, according to the California Highway Patrol.
The big-rig driver then fled the scene of the crash, which was reported on eastbound Highway 262, also called Mission Boulevard, just off of Highway 880 near Kato Road at 1:18 p.m., CHP officials said.
The driver of a truck pulling a chrome double tanker trailer hit the motorcyclist with the rear axle of his truck and then drove away from the collision scene.
The motorcyclist, a Fremont resident riding a 2004 Kawasaki, was pronounced dead on the highway. After searching the area, officers have been unable to locate the big-rig, according to the CHP.
The on- and off-ramps from Mission Boulevard to I-880 were closed for the investigation, CHP officials said, and reopened shortly after 3 p.m.
The CHP is still looking for the big-rig driver. Anyone with information about the crash has been asked to call the CHP at (510) 489-1500 or the CHP's non-emergency tip line at 1-800-TELL-CHP (1-800-835-5247).
