Lakehead, CA (February 20, 2026) – A deadly multi-vehicle pileup involving up to 17 big rigs and passenger vehicles occurred on Tuesday afternoon on Interstate 5 near Gilman Rd, amid severe winter weather conditions in northern Shasta County.
According to the California Highway Patrol, the crash was first reported at 3:05 p.m. in the southbound lanes of I-5, prompting a full closure between Salt Creek Rd and Gilman Rd. Emergency crews responded to the scene and remained on site for several hours due to the scale and complexity of the incident.
Authorities confirmed that one person, a 49-year-old man from Monterey Park who was driving a 2025 Toyota, died in the crash. No other injuries have been officially reported at this time, though multiple vehicles were damaged in the chain-reaction collision.
Southbound I-5 remained shut down into the evening as crews cleared debris and investigated the scene.
Authorities continue to investigate the cause of the crash, and more details will be released as soon as they become available.
We would like to extend our condolences to the family and friends of the deceased victim.
Why Winter Weather Can Lead to Large Pileups on I-5 in Shasta County
Interstate 5 through Shasta County is a major freight and passenger route that frequently sees heavy traffic, especially near Lakehead and other mountainous areas. In winter, snowfall and slick pavement can significantly reduce traction and visibility, making it more difficult for drivers, especially those in large commercial vehicles, to avoid sudden hazards.
Multi-vehicle pileups often begin with a single loss of control, which can quickly escalate when following drivers have little time or space to react. In areas like Gilman Rd, downhill grades and sharp curves can also contribute to reduced stopping distances.
Caltrans and CHP regularly monitor weather conditions and issue chain control advisories, but fast-changing storms can still outpace warnings. These complex, high-impact crashes highlight the need for slower speeds and greater following distances during poor weather.
