A. The public works director or their designee(s) shall have the power and duty to place or cause to be placed official traffic-control devices when and as required to make effective the provisions of this title.

B. Whenever the Vehicle Code 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 public works director or their designee(s) is authorized to install or cause to be installed the necessary devices subject to any limitations or restrictions set forth in the law applicable thereto.

C. The public works director or their designee(s) may also place or cause to be placed such additional traffic-control devices as he or she may deem necessary or proper to regulate traffic or to guide or warn traffic, but he or she 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 this chapter or as may be determined by ordinance or resolution of the council.
