CONCORD -- A 7-year-old girl was expected to survive, but the prognosis for her parents was not as clear after a two-car wreck on Monday that resulted in a Concord man being arrested on suspicion of driving under the influence, the California Highway Patrol said.

The girl was probably strapped into a car seat in the back of her parents' Ford Taurus when it was hit from behind by a blue Toyota Tacoma while the two cars drove westbound on Concord Avenue at 8:20 p.m., CHP Officer John Fransen said. The collision caused the Taurus to barrel roll into a pole, which crushed in most of the left side, Fransen said.

The girls' two parents were taken to John Muir Medical Center in Walnut Creek, where they were in critical condition with serious head injuries Monday night, Fransen said. A nursing supervisor at the hospital declined to release an updated condition for the couple Tuesday afternoon

The girl was taken to Children's Hospital in Oakland with cuts to her face, Fransen said.

According to the CHP, the Taurus had made a right out of the parking lot of a Sam's Club and had gone about 100 feet when the truck slammed into it from behind near the intersection of John Glenn Drive. The wreck caused Concord Avenue to be shut down in the westbound direction for about 30 minutes, Concord police said.

The driver of the Tacoma, Concord resident Jared Bickford, was not seriously injured. He was arrested on suspicion of driving under the influence causing a traffic collision resulting in bodily injury, Fransen said.

The investigation into the wreck is ongoing, he said, and anyone who witnessed the crash is urged to call the CHP's Contra Costa County office at 925-646-4980.
