Motorcyclist Killed On Interstate 580

DUBLIN, CA -- A motorcyclist died Friday afternoon in Dublin after being thrown from the bike and struck by a car. The California Highway Patrol said the incident was reported around 3:49 p.m. on Interstate 580.

The motorcyclist was reportedly splitting lanes between the first and second lane at 30 to 40 miles per hour when a driver in a Porsche changed lanes ahead of the motorcyclist, officials said.

The motorcyclist "locked up the brakes" before losing control of the bike and sideswiping the Porsche, CHP said.

The action forced the motorcyclist to be thrown from the bike before being hit by a driver in a Honda Accord. The motorcyclist was pronounced dead while at the scene, officials said.

All eastbound lanes on the interstate were closed as officials investigated the scene.
