PHOTOS: Clean up for a crash on a northern California freeway turned deadly Saturday after a Tesla plowed into a fire truck that was shielding first responders who were working another accident. The driver of the Tesla Model S was killed when the car hit the truck that was parked on Interstate 680 around 4 a.m., according to the Contra Costa County Fire Protection District. A passenger was also critically injured. Assistant Chief Tracie Dutter said four firefighters who were in the ladder truck were treated for minor injuries. Multiple photos posted on the agency's Facebook page showed the Tesla with a crushed front end and the $1.4 million truck preparing to be towed. Dutter said the truck had its lights on and was parked diagonally in northbound lanes of the freeway to protect first responders who were working an earlier accident that did not result in any injuries.
