Officials say six firefighters suffered major injuries and two others had minor injuries when the hand-crew truck struck a guard rail and overturned.
It apparently was caused by a ladder that was in lanes on the 241 Freeway. A vehicle ahead of the fire truck swerved to avoid the ladder and the truck swerved too, striking the guardrail on the right shoulder and flipping over, according to the California Highway Patrol.
