RIALTO, CA — Five people were killed when a tractor-trailer lost control on the 10 Freeway and crossed the median in Rialto, striking vehicles on the opposite side in a fiery wreck that shut down the roadway for hours. Authorities said the crash involved at least three other vehicles, including a motorcycle, and left the freeway closed in both directions as investigators worked the scene.
Video and photos from the aftermath showed the trailer on its side and engulfed in flames. By evening, only burned-out shells of the truck and several other vehicles remained. Investigators have not said what caused the driver to lose control, and the circumstances of the crash were still being sorted out late that day.
Truck veers across the median and into eastbound traffic
According to authorities, the semi was traveling on the westbound side of the freeway when it lost control and drove through the center divider. It then slammed into traffic moving in the opposite direction on the eastbound side, creating a chain-reaction collision that involved multiple vehicles.
The violent impact and fire made the crash especially destructive. Officials said the freeway remained closed for hours while emergency crews responded and investigators examined the scene. KABC reported that the eastbound lanes were expected to stay shut until 3 a.m., underscoring how long the cleanup and investigation were expected to take.
Fire and wreckage left the freeway closed for hours
The crash brought traffic to a standstill on one of Southern California’s major routes. Both directions of the 10 Freeway were shut down for hours after the collision, a major disruption for drivers in the Inland Empire corridor east of Los Angeles.
As the wreck burned, onlookers captured images that showed the trailer lying on its side and flames spreading through the crash scene. By the time the fire was out, the damage was severe enough that the roadway was left with charred vehicle hulks and debris across the lanes. The closure lasted well into the night as crews continued their work.
At least three other vehicles were caught in the collision
Authorities said the semi was not the only vehicle involved. At least three other vehicles were caught up in the crash, including a motorcycle, adding to the scale of the pileup and the number of people exposed to the impact.
Officials did not immediately release details about the occupants of the other vehicles or the condition of anyone who may have survived. What was clear from the scene, however, was that the collision extended far beyond the truck itself and spread across multiple lanes, turning a single loss of control into a deadly freeway disaster.
Investigators have not said what caused the driver to lose control
Even as the wreckage was being cleared, investigators were still trying to determine why the tractor-trailer veered out of its lane. KABC reported that it remained unclear what led to the loss of control, and officials had not publicly identified a cause.
That question is central to the investigation because it could determine whether the crash was caused by a mechanical problem, driver error, road conditions or another factor. For now, authorities have only confirmed the path of the truck, the number of dead and the extent of the damage, while the reason behind the deadly sequence remains unanswered.
Rialto crash underscores the danger of high-speed freeway pileups
The wreck happened in Rialto, about an hour east of Los Angeles, on a freeway that carries heavy regional traffic every day. When a tractor-trailer crosses into oncoming lanes at speed, the consequences can be catastrophic, especially when the impact triggers fire and involves several vehicles at once.
This crash combined all of those dangers. The median crossing, the multi-vehicle collision and the blaze turned an ordinary stretch of interstate into a fatal emergency scene. With five people dead and investigators still searching for answers, the crash stands as one of the most severe freeway accidents in the area in recent memory.
