Aerial TV news footage showed skid marks streaking across the freeway behind the crash site.Jeff Lewis, a truck driver and former firefighter in the military, said he was driving behind the bus when it slammed on the brakes.Seconds later, with the bus resting on its side, Lewis said he and five or six others got out of their cars and helped pop open the front window to help passengers climb out one-by-one.last_img read more
