An authorized emergency vehicle operated as a police vehicle need not be equipped with or display a light visible from in front of the vehicle.
(C) 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 reckless disregard for the safety of others. It is not the intent or purpose of this section to hamper or interfere with the powers and duties of the Fire Department or Police Department in the exercise of their several functions, or to render the city in any respect liable for any damages of or injuries to persons or property occasioned in the exercise of these functions by the city.
