CHP shared photos of an overturned semi-truck on SR-78 near Jefferson on March 24, 2025.
Drivers in the North County should expect delays Monday after a semi-truck crashed into a center divider of state Route 78 in Oceanside, affecting traffic on both sides of the freeway.
The truck was heading westbound on SR-78 near Jefferson Drive at about 7:40 a.m. when for unknown reasons it struck a car, California Highway Patrol officer Hunter Gerber said. The truck swerved to the left and struck another vehicle, causing both that car and the semi-truck to roll over.
As the truck crashed into the center divider, it struck another vehicle and sent debris flying that ricocheted into two other vehicles, Gerber said.
Photos from the scene after the crash showed a cement truck on its side and stretched along both eastbound and westbound SR-78, with its neck hugging the center divider.
