A single vehicle accident in unincorporated Contra Costa County on Friday night severely maimed one boy and caused five other people to be transferred to local hospitals, the California Highway Patrol said.
At about 10:25 p.m. Friday, a 1998 Toyota Land Cruiser that was traveling northbound on Vasco Road just north of the Alameda County line veered off the roadway after executing "an unsafe turning maneuver," according to a CHP report of the crash.
The sports utility vehicle - which was carrying one adult driver, three 11-year-old boys and two 12-year-old boys - hit a dirt embankment on the east shoulder of the road and rolled over, launching two of the juveniles out of the vehicle, CHP said.
The left arm of a 12-year-old boy who was ejected from the car was partially amputated below the elbow in the crash, according to CHP Officer Ralph Caggiano. That boy also had a laceration on his left leg, Caggiano said.
The other juveniles all reportedly suffered minor injuries in the crash, ranging from complaints of pain to a minor laceration on one of the 11-year-olds, the report said.
The severely injured boy and the other juvenile who was thrown from the car were air-lifted to Children's Hospital in Oakland, the CHP report said. The other three boys and the driver, a 33-year-old man from Oakley, were taken by ambulance to Sutter Delta Medical Center in Antioch.
Three of the juveniles, including the boy whose arm was severed, were not wearing seat belts, CHP said. It was determined that alcohol was not a factor in this crash, they reported.
Vasco Road has historically been a particularly dangerous stretch of roadway in Contra Costa County, claiming 16 lives between 1996 and 2008.
A two-part safety improvement project that will widen the road and create a median barrier along the most dangerous 2.5 miles of the route broke ground on May 24. The project is expected to be completed in late 2011.
