A massive accident on Highway 84 on Friday left 10 people injured, including a Texas Department of Public Safety trooper who was struck by a big rig.

A camera crew on-scene recording footage of an initial crash involving two-vehicles captured a semi-truck emerge from the dense fog and slam into two vehicles, turning onto its side and crushing a Texas DPS vehicle. The crash sent several DPS officials on-scene running for the lives.

According to KCBD, four semi-trucks and four other vehicles were involved in the massive crash.

A Texas DPS trooper was struck by the semi-truck and transported to University Medical Center. He suffered a sprained ankle, bruising to his ribs and back, and a cut on the back of his head, the group said. Late Friday night, he was released from the hospital.

Another driver was trapped in his vehicle after the semi-truck's trailer crushed it. First responders were able to free him from the wreckage. He was also transported to UMC, where he was listed in stable condition.
