Patterson, CA (May 2, 2026) – A semi-truck rollover crash shut down both directions of Interstate 5 on Friday morning near Patterson. The incident occurred shortly before 10:00 a.m. just north of Sperry Avenue.
Emergency units responded to the scene and found the overturned truck on its side in the median. Investigators said the driver turned left for unknown reasons and entered the median before attempting to regain control, causing the truck to overturn.
A 43-year-old man from Bakersfield who was inside the sleeper area of the truck suffered major injuries. He was taken to a hospital by helicopter. The driver, a 58-year-old man from Fillmore, sustained minor injuries and was also taken to a hospital.
The truck was hauling refrigerated liquid hydrogen, and reports of a gas odor led to a full closure of the interstate in both directions. Crews worked to secure the scene before reopening southbound lanes around 1:30 p.m. Northbound lanes reopened later in the afternoon.
Authorities continue to investigate the cause of the crash, and more details will be released as soon as they become available. We are thinking of those injured as they receive medical care.
How Hazardous Cargo Can Affect Highway Crash Response
When a crash involves a vehicle carrying hazardous materials, the response process can become more complex. Substances like liquid hydrogen require careful handling due to potential risks such as leaks or vapor release.
Emergency crews may close roads to create a safe perimeter while they assess the situation. Specialized teams are often called to evaluate the cargo and ensure there is no immediate danger to the public.
The type of material being transported can influence how long a roadway remains closed. Cleanup and safety checks must be completed before traffic can safely resume.
