(A) The provisions of this title shall not apply to any authorized emergency vessel actually responding to an emergency call or in immediate pursuit of an actual or suspected violator of the law, within the purpose for which such emergency vessel has been authorized; provided that the provisions of this section shall not relieve the operator of an authorized emergency vessel of the duty to operate with due regard for the safety of all persons, nor shall it protect the operator of such vessel from the consequence of reckless disregard for the safety of others; provided further that the provisions of this section shall in no event extend any special privilege or immunity in the operation of an authorized emergency vessel for any purpose other than that for which has been authorized.
(B) In a case where loss of life, personal injury and/or substantial damage to property or natural resources occurs or is threatened, an authorized emergency vessel actually responding to such casualty may, when the operator of such emergency vessel in good faith believes it to be necessary and appropriate, operate such emergency vessel in a way that produces a wake, wash or wave action which may or could be expected to damage another vessel or property therein or create discomfort to an occupant of another vessel; provided that the provisions of this subsection shall not apply when such wake, wash or wave action itself could lead to loss of life, personal injury and/or substantial damage to property or natural resources.
