Four people were injured in the series of crashes that occurred at a road construction site where traffic was stopped in the southbound direction on Highway 113 in rural Sutter County.
An oncoming big rig traveling southbound either failed to brake or his brakes did not correctly function, according to the CHP. His rig failed to stop, rear-ending a Dodge pickup pulling a boat.
The boat went off the right shoulder and the pickup went left into a canal. Before the Dodge pickup went off the road it rear-ended a Ford pickup that was carrying a white powdery substance used in agriculture to prevent sunburn on plants and trees.
The powder was spread over the pavement and along the highway. The two pickups ended up on the left side of the road and were pinned by the big rig down off the roadway.
The Ford pickup also rear-ended a Honda car, which was then shoved into a big rig hauling logs.
The CHP said the driver and passenger in the Honda and the Ford pickup driver were taken to the hospital by helicopter. The driver of the Dodge pickup was transported by ambulance.
Conditions of those transported to the hospital were not immediately available.
