Two people were believed to have been in the Thunderbird that fled the area without stopping, CHP Officer Jonathan Sloat said.
Officer Juan Leon was on a traffic stop on the right shoulder of northbound U.S. Highway 101 between Steele Lane and Bicentennial Way when the incident happened around 8:30 p.m., Sloat said.
While Leon and the motorist were outside their vehicles, the Thunderbird approached them as it traveled north on the Steele Lane onramp.
The Thunderbird veered to the right and struck the left side of the patrol car causing moderate damage to both vehicles, Sloat said. The driver of the Ford exited the highway onto Bicentennial Way, the CHP said.
Neither Leon nor the motorist he stopped was injured. The CHP searched the area but did not find the Thunderbird, which has damage on its right side, Sloat said.
The CHP is asking anyone with information about the Ford or the accident to call (707) 588-1400.
