A. The public works director or their designee(s) is directed to install official traffic signals at those intersections and other places where traffic conditions are such as to require that the flow of traffic be alternately interrupted and released in order to prevent or relieve traffic congestion or to protect life or property from exceptional hazard.

B. The public works director or their designee(s) shall ascertain and determine the locations where such signals are required by field investigation, traffic counts and other traffic information as may be pertinent and his or her determinations therefrom shall be made in accordance with those traffic engineering and safety standards and instructions set forth in the Traffic Manual issued by the California Department of Transportation.

C. Whenever the public works director or their designee(s) installs an official traffic signal at any intersection, he or she shall likewise erect at such intersection street name signs visible to the principal flow of traffic unless such street name signs have previously been placed and are maintained at any such intersection.
