A law enforcement officer shall permit any first aid, rescue or ambulance squad member, or any physician or surgeon licensed to practice medicine or surgery under chapter 9 of Title 45 of the Revised Statutes, to provide medical aid that the member, physician or surgeon considers appropriate to an injured person, unless in the judgment of the law enforcement officer in charge, considerations of the public health, safety and welfare are of overriding concern in a particular situation.

Law enforcement officers shall recognize and implement the public policy set forth in this section.
