An investigation is underway after multiple people are recovering following a crash involving a Tennessee Highway Patrol trooper who was responding to a separate crash.

Preliminary reports say the first crash involved a 33 year old man who was going South on Maynardville Highway hitting a guardrail before spinning out of control, crossing the center line and hitting another car. Two people were injured in that crash. Charges are pending against the driver.

The second crash also happened on Maynardville Highway just past Raccoon Valley Road. A trooper was responding to the first crash with his lights and sirens on when a driver pulled in front of the trooper, the trooper hit that car causing both of them to run off of the road. Both drivers and a three-year old inside of that car were injured.
