A dashcam captured a truck swing out of control on highway in San Jose, California, on June 9.

In the video, a truck pulling a trailer is seen veering out of control. A bigger tractor-trailer truck ends up colliding with the smaller truck as debris spreads across the highway.

The filmer said he “watched in horror" as the trailer swung out of control and praised emergency medical technicians (EMTs) for arriving quickly to aid the victims.
