The girl, whose name has not been released because she is a juvenile, faces charges of driving under the influence of drugs or alcohol, reckless driving, leaving the scene of a collision, possession of marijuana and assault with a deadly weapon.
The incident began at about 9:10 a.m. when Cpl. William Downes drove onto Irwin Court and saw an occupied black BMW parked on the wrong side of the road, police said.
The female driver immediately sped off toward Forest View Avenue upon seeing the police car, and when Downes arrived at the intersection, he discovered that the BMW had broadsided a Cadillac sedan.
The Cadillac was turned sideways from the collision, blocking both lanes of Forest View Avenue. The BMW driver then started ramming the side of the Cadillac to try to create an escape route, and drove away from the scene south on Forest View Avenue.
The 45-year-old female driver of the Cadillac said she was not injured from the collisions, police said.
While Downes assisted the Cadillac driver, additional Hillsborough police officers searched for the BMW, which was spotted and pulled over at the intersection of Sharon and Floribunda avenues, police said.
The 16-year-old girl was taken to the San Mateo County Juvenile Detention Facility while a 16-year-old male passenger was transported to the police station for questioning before being released to a parent.
