PLEASANTON — A man driving on Interstate 580 escaped injury Monday night after shots were fired at him in the Bay Area’s second freeway shooting in four days, authorities said.

The California Highway Patrol notified Pleasanton police around 7 p.m. about the shooting, which happened on westbound I-580 between Hacienda Drive and Hopyard Road, Pleasanton police Sgt. Jerry Niceley said. The man told officers that something sparked road rage in the occupants of a silver Toyota Corolla.

The passenger of that car reportedly fired a black handgun more than once, Niceley said.

The shots did not hit anybody, and no other motorists on the freeway were injured. The Toyota sped away west toward Oakland.

The shooting came three days after 28-year-old Antioch resident Braun Harold was fatally shot in the head while driving on eastbound Highway 4 just west of the Hillcrest Avenue exit. Police have not made any arrests in that incident, which CHP spokesman Officer John Fransen said was the ninth freeway shooting reported in the East Bay in 2017.

Anyone who may have witnessed something suspicious in the area around the time of the shooting can call Pleasanton police at 925-931-5100.
