A Sebastopol woman, suspected of driving under the influence of alcohol or drugs, crashed into a power pole early Tuesday off of Highway 116 south of Sebastopol, the CHP said.
The impact caused substantial damage and required a PG&E crew to replace two poles and two transformers, according to a utility company spokeswoman.
Eight customers in the area lost power, six of them for almost 12 hours.
At about 1:30 a.m. Larisa Shevchuk, 23, was driving toward Sebastopol when she lost control near Todd Road and Old Gravenstein Highway South. Her car ran off of the roadway into the pole.
Shevchuk was crawling out of the wrecked car as an ambulance and firefighters arrived.
After she was out, her car caught fire and Gold Ridge firefighters doused the flames.
Shevchuk suffered injuries including a broken arm and cuts to her chest and forehead.
She was taken to Santa Rosa Memorial Hospital. At about 3:30 a.m., officers arrested her on suspicion of DUI but released her to the hospital, according to the CHP.
