According to CHP spokesman Dan Gilmore, the woman was driving a white Honda Civic. "The vehicle went westbound in the eastbound lanes," he said. "It struck several vehicles — a Nissan and a silver Honda. It sideswiped both of those vehicles. Then it hit a Jeep Grand Cherokee head on."

Flipped car, minor injuries

Nobody was injured in the first two vehicles that were sideswiped. When the woman's car hit the Jeep, her vehicle flipped over. The driver of the Jeep suffered minor injuries. All four lanes of the road were closed after the accident, causing a major traffic jam; all lanes reopened around 7 p.m.

Both occupants arrested

A male adult passenger fled from the wrecked Civic on foot and was caught and arrested by police. The woman was arrested at the scene. Gilmore said he did not know why deputies were chasing the woman or why she drove the wrong way. Drugs and alcohol appeared not to have been involved.
