The two-vehicle collision occurred at around 11 p.m. Saturday on Spruce Grove Road about three miles east of Highway 29, according to an initial report from the California Highway Patrol.
Witnesses reported two vehicles were driving recklessly and chasing each other before one of the cars lost control and slammed into a power pole, knocking it and wires down across the road, the CHP reported.
Firefighters, Pacific Gas & Electric and county road crews responded to the scene along with the CHP.
A child was reportedly injured in the crash; the CHP reported that the child was transported to Children's Hospital & Research Center of Oakland.
The road remained closed for many hours on Saturday as road crews dealt with the pole. The damage to the pole was reported to have knocked out power to residences in the Hidden Valley Lake area.
Additional specifics on injuries or the circumstances of the crash weren't immediately available.
