KNOXVILLE, Tenn. (WATE) — A woman was seriously injured early Wednesday morning when she was struck by an oncoming vehicle after stopping to help another crash victim on Alcoa Highway.

Emergency crews responded to a single-vehicle crash on southbound Alcoa Highway near the Kingston Pike exit around 5:22 a.m. Wednesday. The crash victim struck the inside concrete barrier and came to a stop in the left lane.

Two vehicles not involved in the crash stopped to help the driver in the single-vehicle crash when another vehicle drove between the two parked cars and struck a woman who had also stopped to assist in the crash.

The female pedestrian was seriously injured as a result of the crash and transported to the UT Medical Center for immediate medical treatment. No other injuries were reported in either collision.

A investigation by the KPD crash reconstruction team is ongoing. Once that investigation is complete, the file will be turned over to the Knox County District Attorney’s Office to make a determination regarding charges and prosecution.
