VEST, Ky. (WMDJ) — An Ohio man was killed Friday afternoon when the utility terrain vehicle he was driving overturned on an off-road trail in Knott County.

Kentucky State Police say Lance Walters, 44, of London, Ohio, was operating a UTV at Mine Made Adventure Park in the Vest community when he attempted to avoid a rock on the trail.

According to investigators, the maneuver caused the vehicle to leave the trail and travel over a steep embankment, overturning multiple times.

Walters suffered fatal injuries and was pronounced dead at the scene by the Knott County Coroner’s Office.

A passenger was transported by ambulance to Hazard ARH for treatment of non-life-threatening injuries.

Police say both occupants were wearing seat belts, but neither was wearing a helmet.

Troopers responded to the crash shortly before 1:30 p.m. Friday.

Toxicology results are pending, and the crash remains under investigation by Kentucky State Police Post 13.
