§ 70.01  TRAFFIC-CONTROL DEVICES.
   (A)   The Commission shall 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, and may place and maintain such additional official traffic-control devices as the Commission may deem necessary to regulate, warn or guide traffic under the traffic ordinances of this city or the Kentucky Revised Statutes.
   (B)   All traffic-control signs, signals and devices shall conform to the manual and specifications approved by the resolution adopted by the legislative body of this city.  All signs and signals required hereunder for a particular purpose shall so far as practicable be uniform as to type and location throughout the city.  All traffic-control devices so erected and not inconsistent with the provisions of state law or this section shall be official traffic-control devices.
   (C)   The driver of any vehicle shall obey the instructions of any official traffic-control device applicable thereto placed in accordance with the provisions of this section, unless otherwise directed by a traffic or police officer, subject to the exceptions granted the driver of an authorized emergency vehicle.
   (D)   No provision of this section for which official traffic-control devices are required shall be enforced against an alleged violator if at the time and place of the alleged violation an official device is not in proper position and sufficiently legible to be seen by an ordinarily observant person.  Whenever a particular section does not state that official traffic-control devices are required, such section shall be effective even though no devices are erected or in place.
   (E)   (1)   Whenever official traffic-control devices are placed in position approximately conforming to the requirements of this section, such devices shall be presumed to have been so placed by the official act or direction of lawful authority, unless the contrary shall be established by competent evidence.
      (2)   Any official traffic-control device placed pursuant to the provisions of this section and purporting to conform to the lawful requirements pertaining to such devices shall be presumed to comply with the requirements of this section, unless the contrary shall be established by competent evidence.
