New Jersey Statutes Title 5. Amusements, Public Exhibitions and Meetings 5 § 3-46

a. The owner and ride operator shall retain at all times up-to-date maintenance and inspection records for each carnival-amusement ride in accordance with such rules and regulations as the department may prescribe. Among other things, such records shall contain information of the date and nature of all inspections, whether by a departmental inspector or a person in the employment of the owner or of any insurer of the carnival-amusement ride, as well as of any violations and the types of actions taken to rectify the violations. All breakdowns or repairs of any mechanical part shall be duly noted. The department may also require a full safety inspection of any ride whose operation results in any injury or death before operation of that ride can be resumed.

b. The department shall conduct an investigation of each carnival-amusement ride incident in which one or more persons suffer death or serious injury and shall identify those measures which may be required to prevent the future occurrence of death or serious injury under similar circumstances and, in furtherance of any investigation pursuant to this subsection, the department may issue and enforce subpoenas to compel the testimony of any person who may have knowledge of any relevant matters and the production of any relevant documents.
