The CHP was informed by the Alameda County Sheriff's Office around 12:15 a.m. about a pursuit of a white Honda Accord, most likely because it was stolen, CHP Officer Marc Johnston said.
Officers suspended the chase around 1 a.m., after the two incidents, and are still looking for the Honda, Johnston said.
He said the first incident occurred in Hayward on southbound Interstate Highway 880 near Jackson St.
The second was reportedly in unincorporated Contra Costa County on eastbound Interstate Highway 80's San Pablo Avenue off-ramp.
No injuries were reported, Johnston said.
