The speed limit set out in this subchapter does not apply to authorized emergency vehicles when responding to emergency calls provided the drivers thereof sound audible signals by siren or horn and two lighted red lights are displayed to the front, or one beacon light visible 360 degrees, or to authorized emergency vehicles operated by peace officers who are measuring the speed of other vehicles by use of the emergency vehicle speedometer. This section shall not relieve the driver of any authorized emergency vehicle from the duty to driver with due regard for the safety of all persons using the street nor shall it protect the driver of any vehicle from the consequence of a reckless disregard of the safety of others.
