The New Jersey Attorney General's Vehicle Pursuit Rules require each law enforcement agency to annually prepare a "Vehicular Pursuit Summary Report" setting forth the number of police vehicle pursuits and the number of accidents, injuries and deaths resulting from those pursuits. I collected examples of these summary reports from two police departments at opposite ends of the state--Bridgeton (Cumberland County) and Mahwah (Bergen County). I have placed the reports on-line here.
The reports help citizens get a sense as to how frequent police chases are in their towns. They also provide information that can lead to additional Open Public Records Act (OPRA) requests. For example, Bridgeton's 2013 report shows that one police injury and one police car accident occurred during a high speed chase. Interested citizens could request the police report for that incident.
