Rippy v. Shepard, 80 So.3d 305 (Fla. Sup. Ct. 2012)

(plaintiff sued the owner of a farm tractor for vicarious liability under the dangerous instrumentality doctrine after sustaining injuries caused by defendant’s tractor; in reviewing a motion to dismiss, the court determined a farm tractor is a dangerous instrumentality because it is defined as a motor vehicle under Florida law; doctrine is not limited to motor vehicles operating solely on public highways and Florida regulations ensure safe operation of farm tractors; court also reasoned that tractors can be dangerous to those who come in contact with them)
