A sedan slid underneath a loaded tractor-trailer on Interstate 10 in Fontana, trapping the car's lone occupant. The occupant was awake and responsive, and a patient was transported to a trauma center, while the tractor-trailer driver was not injured.
The collision happened just east of the Sierra Avenue on-ramp. A verified San Bernardino County Fire account was identified in connection with the incident. The sedan was wedged beneath the trailer with its driver trapped inside, and rescuers worked around the vehicle. The lone occupant was awake and responsive as rescuers worked.
Specialized Rescue Crews Called to the Scene
The response drew on county fire department resources. Firefighters worked at the scene while the sedan remained wedged beneath the trailer and its occupant was trapped inside.
A patient was transported to a local trauma center, but the available information does not specify which facility received them. San Bernardino County has two verified Level I trauma centers capable of handling severe crash injuries: Arrowhead Regional Medical Center's Dev A. GnanaDev Level I Trauma Center in Colton and Loma Linda University Medical Center, which holds dual Level I designations for both adult and pediatric care.
Limited Details on Other Incidents
The available information does not provide details of other incidents near that stretch of freeway.
The stretch of I-10 running through south Fontana is one of the busiest freight corridors in the Inland Empire, carrying between 200,000 and 230,000 vehicles a day across the Sierra Avenue, Citrus Avenue and Cherry Avenue interchanges, according to the Yaghmai Law Firm. Much of that traffic is generated locally: Fontana's Slover Avenue and Valley Boulevard corridors host major logistics and distribution hubs for companies including Amazon, Target and FedEx, funneling heavy volumes of tractor-trailers onto the freeway alongside daily commuter traffic.
Underride Crash Risks
The incident involved a sedan lodged beneath a trailer, a configuration that can complicate rescue operations. The available information does not establish which federal standards or initiatives, if any, apply to this collision.
It remains unclear what led to the collision or how the sedan came to be lodged beneath the trailer. Fontana has seen other crashes, including a fatal crash on Arrow Boulevard in this earlier Fontana collision where a vehicle hit a tree and caught fire.
