A massive chain-reaction crash involving 59 vehicles forced the closure of both directions of Highway 99 in Tulare County, Central California, early Saturday morning, according to the California Highway Patrol. The collision occurred between Delano and Earlimart and involved a mix of semi-trucks and passenger vehicles, leaving twisted wreckage scattered across the roadway.

CHP investigators say dense fog was a significant factor in the crash, with visibility estimated at just 100 to 200 feet at the time of the incident. The limited visibility is believed to have triggered a rapid series of collisions as drivers were unable to react in time to stopped or slowing traffic ahead.

Ten people were injured and transported to area hospitals for treatment. Authorities confirmed that no fatalities were reported. Several other motorists who were not injured were transported by bus to a nearby shelter as emergency crews worked to clear the scene and ensure their safety.

Initial reports suggested the crash may have involved as many as 150 vehicles, but CHP later confirmed that 59 vehicles were ultimately accounted for. Both northbound and southbound lanes of Highway 99 remained closed for several hours while responders removed damaged vehicles, including multiple semi-trucks, and addressed fuel spills and debris.

By Saturday evening, Highway 99 was fully reopened to traffic. The incident once again highlights the dangers of Central Valley fog, which regularly creates hazardous driving conditions during winter months. Authorities urged motorists to slow down, increase following distance, and use caution when visibility is severely reduced, emphasizing that chain-reaction crashes remain one of the most serious risks in fog-prone areas.
