An ATV crash in Muhlenberg County Saturday afternoon injured a Greenville man. According to Kentucky State Police, the accident happened around 3:30 five miles south of Greenville. 55-year-old Johnny Lanier was traveling south in a 2005 Polaris Sportsman ATV as he attempted to negotiate a curve. Troopers say Lanier experienced a mechanical problem and he lost control, exiting the left side of the roadway and striking a culvert. The ATV flipped over on top of Lanier. He was flown to Vanderbilt in Nashville for treatment.
