An 8-year-old girl was killed when an ATV, operated by an 11-year-old, flipped over.

The fatal crash occurred around 7:10 p.m. Friday on Thomas Road in Union Township, Tioga County, according to the Pennsylvania State Police.

An 11-year-old girl was operating an Arctic Cat ATV with two passengers -- a 16-year-old girl and the 8-year-old.

As the driver attempted to make a left-hand turn at a high rate of speed off of the single-lane Thomas Road, the ATV flipped sideways, tipped over, and pinned the three underneath.

The girls were rushed to area hospitals, and the 8-year-old was pronounced dead shortly after she was transported, according to police.

Their identities have not been released.
