A Florida Jet Ski accident leaves a man unconscious.  The accident occurred on December 3, 2017 and was videoed by an off-duty policeman who was the first on the scene to render assistance.  Despite wearing a lanyard attached to a switch designed to cut off the engine when the rider is thrown off the Jet Ski, the machine was still running after the accident.  It is unknown at this time if the Jet Ski was rented or owned by the rider.  Florida has strict laws concerning the renting of all personal watercrafts including Jet Skis.  These laws require the rental company to provide detailed instruction on the safe handling and navigation of these watercrafts.  If these instructions are not properly given, a court may find the rental company liable for the accident.  It has been reported that the victim is making a steady recovery.
