The three-car accident was reported at the Rosecrans Avenue off-ramp at about 2 p.m. Authorities say a blue semi-truck and a white car were trying to make a lane change at the same time. The blue truck hit the white car, sending it spinning out of control.
A Caltrans worker who was picking up trash on the side of the roadway was hit by the white car. She was rushed to a local hospital with injuries to her lower extremities.
Three people in the white car, including a young child, were also rushed to a local hospital in critical condition. The driver of the truck was expected to be OK.
