Simultaneous crashes reported. In the event an officer is notified of more than one crash at about the same time discretion will be exercised as to the priority of investigation. Consideration will be given to factors such as severity of crash, highway blockage, failure to stop and render aid, amount of traffic at location, potential for the crash to become worse, danger of fire or explosion, and any other information that is available.
