The Orange County Fire Authority truck overturned on State Route 241 at about 6:50 p.m. local time in the Portola Springs area near State Route 133, according to the California Highway Patrol. A ladder in the roadway caused the fire truck and another vehicle in front of it to swerve, highway patrol said. The truck collided with a nearby guard rail and overturned. It did not appear that any other vehicles were involved. Initially, highway patrol reported that 12 firefighters were injured, but later downgraded that to eight. Six suffered “very serious” injuries and two minor injuries, a highway patrol officer at the crash site said.
