ONTARIO, Calif. – Three people were killed, and several others were injured following a horrific chain-reaction crash in Ontario Tuesday afternoon.
Dash camera video, appearing to be from the big rig that slammed into several vehicles on the westbound 10 Freeway Tuesday, is making the rounds on social media.
Fiery eight-vehicle crash
What we know:
Officials said the driver of a semi-truck, identified by FOX News’ Bill Melugin as Jashanpreet Singh, allegedly failed to stop on time leading up to the crash. Singh has since been arrested over allegations of possibly driving under the influence of drugs.
Just a loud explosion, something you don’t ever expect to see,” said Jason Calmelat.
California Highway Patrol officers responded to a multi-vehicle crash on the westbound lanes of the 10 Freeway, west of the 15 Freeway, around 1:10 p.m. Tuesday, Oct. 21.
CHP investigators said the preliminary investigation reveals traffic had slowed or stopped when Singh allegedly failed to stop the semi-truck on time, leading to a chain-reaction crash that involved eight vehicles. Four of the eight vehicles were commercial vehicles.
People in a parking lot overlooking the freeway witnessed the crash in horror. “To see it actually unfold the way it did was pretty frightening,” said Calmelat. “It was so horrific. He was going so fast and cars were, there was no chance they were going to get away from that.”
Three people were pronounced dead at the scene, and at least four others were hospitalized for injuries ranging from minor to major as onlookers watched the investigation.
“You couldn’t tell they were cars, it just looked like a bunch of metal smashed up and balled up. It was really sad,” said Angela, who saw the aftermath.
In addition, fuel from the semi-truck spilled onto the dirt shoulder of the freeway, resulting in a hazardous material incident. Multiple lanes were closed for hours.

The names of the victims have not been released.
