(1) The chief of police shall have the exclusive power and duty to place and maintain or cause to be placed and maintained official traffic-control devices when and as required under the traffic ordinances of this city to make effective the provisions of said ordinances.

(2) Whenever the Vehicle Code of this state requires for the effectiveness of any provision thereof that traffic-control devices be installed to give notice to the public of the application of such law, the chief of police is authorized to install the necessary devices subject to any limitations or restrictions set forth in the law applicable thereto.

(3) The chief of police may also place and maintain such additional traffic-control devices as he may deem necessary to regulate traffic or to guide or warn traffic, but he shall make such determination only upon the basis of traffic engineering principles and traffic investigations and in accordance with such standards, limitations and rules as may be set forth in the traffic ordinances of this city or as may be determined by ordinance or resolution of the legislative body of this city.

(Ord. No. 396, §§ 1, 2.)

No provision of the Vehicle Code or this chapter for which signs are required shall be enforced against an alleged violator unless appropriate signs are in place and sufficiently legible to be seen by an ordinarily observant person, giving notice of such provisions of the traffic laws.

The driver of any vehicle shall obey the instructions of any official traffic control device applicable thereto and placed in accordance with the traffic ordinances of this city, unless otherwise directed by a police officer subject to the exceptions granted the driver of an authorized emergency vehicle when responding to emergency calls.

(Ord. No. 396, §§ 1, 2.)

(1) The chief of police is directed to install and maintain 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.

(2) The chief of police shall ascertain and determine the locations where such signals are required by resort to field observation traffic-counts and other traffic information as may be pertinent and his determinations therefrom shall be made in accordance with those traffic engineering and safety standards and instructions set forth in the California Maintenance Manual issued by the Division of Highways of the State Department of Public Works.

(3) Whenever the chief of police installs and maintains an official traffic signal at any intersection, he shall likewise erect and maintain 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 said intersection.

(Ord. No. 396, §§ 1, 2.)

Whenever the State Department of Public Works determines by resolution and designates a distinctive roadway marking which shall indicate no driving over such marking, the chief of police is authorized to designate by such marking those streets or parts of streets where the volume of traffic, or the vertical or other curvature of the roadway, renders it hazardous to drive on the left side of such markings or signs and markings. Such markings or signs and markings shall have the same effect as similar markings placed by the State Department of Public Works pursuant to provisions of the Vehicle Code.

(Ord. No. 396, §§ 1, 2.)
