News crew capture the moment an out-of-control truck collides into accident scene

Heart-pounding footage has emerged of a semi-truck crashing into a pile-up in Lubbock County, Texas.

The incident took place on Highway 84, where KCBD had a crew filming an initial pile-up. However, in a startling moment, an out of control truck comes speeding through the fog and crashes into the stalled cars at the side of the road.

The crash resulted in on DPS trooper being hit and pinned a person to the inside of a truck. Both subsequently received medical treatment, but their condition has not been described as life-threatening, as per KCBD.

The semi flipped over as it hit the pile-up, causing its trailer to swing around and strike the trooper.

According to reports, DPS had initially responded to a two-vehicle crash at one mile east of Slaton on US 84 at around 10:45am - a crash that blocked both westbound lanes of US 84.

As a result of the semi crashing into the pile-up, several more vehicles collided into the back of it.

The driver of the vehicle lost control as they were approaching the scene when a red SUV suddenly changed lanes. This resulted in the jackknife which caused the vehicle to roll over onto its side.

First responders were able to rescue the person pinned to the inside of a truck. He was said to have sustained serious injuries, which he later received treatment for at University Medical Center in Lubbock.

To put the scale of the incident into context, there were five crashes in total involving four semi tractor-trailers and four smaller vehicles.

Seven units from the Lubbock Fire Department were dispatched to the scene, containing 19 members of the emergency services. Meanwhile, LFD sent its division chief, battalion chief, command assistant, three heavy rescue team units, an additional engine, and aerial assistance.

The accidents were, in part, the result of dense fog in the area which has resulted in hazardous driving conditions across the South Plains. According to weather reports, it is expected to lift by Friday afternoon.
