(A)   The driver of an authorized emergency vehicle, when responding to an emergency call or when in the pursuit or an actual or suspected violator of the law or ordinance or when responding to but not upon returning from a fire alarm, may exercise the privileges set forth in this section, but subject to the conditions herein stated.
   (B)   The driver of an authorized emergency vehicle may:
      (1)   Park or stand, irrespective of the provisions of this article;
      (2)   Proceed past a red or stop signal or stop sign, but only after slowing down as may be necessary for safe operation;
      (3)   Exceed the maximum speed limits so long as he or she does not endanger life or property; and
      (4)   Disregard regulations governing direction of movement or turning in specific directions.
   (C)   The exemptions herein granted to an authorized emergency vehicle shall apply only when the driver of any vehicle is making use of audible and visual signals as required by law, except that an authorized emergency vehicle operated as a police vehicle need not be equipped with or display a red light visible from in front of the vehicle.  This division shall not be construed as requiring a peace officer operating a police vehicle properly and lawfully in response to a crime in progress to use audible signals.
   (D)   The foregoing provisions shall not relieve the driver of an  authorized emergency vehicle from the duty to drive with due regard for the safety of all persons, nor shall the provisions protect the driver from the consequences of his or her reckless disregard for the safety of others.
