(A) Authority to install traffic-control devices. The County Commissioners, acting through their delegated agents, shall place and maintain official traffic-control devices when and as required under the traffic ordinances of this county to make effective the provisions of said ordinances. They may place and maintain such additional official traffic-control devices as they may deem necessary to regulate, warn or guide traffic under the traffic ordinances of this county or the state vehicle laws.
(B) Manual and specifications for traffic-control devices. All traffic-control signs, signals and devices shall conform to the Indiana Manual on Uniform Traffic Control Devices for Streets and Highways. All signs and signals required hereunder for a particular purpose shall, be uniform as to type and location throughout the county. All traffic-control devices so erected, and not inconsistent with the provisions of state law or this traffic code, shall be official traffic-control devices.
(C) When official traffic-control devices are required for enforcement purposes. No provision of this traffic code 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.
(D) Interference with official traffic-control devices. No person shall, without lawful authority, attempt to or in fact alter, injure, knock down or remove any official traffic-control device or any railroad sign or signal or any inscription, shield or insignia thereon, or any part thereof.
(E) Official traffic-control devices; presumption of legality. Whenever official traffic-control devices are placed in positions approximately conforming to the requirements of this traffic code, such devices shall be presumed to have been so placed by the official act or direction of lawful authority and to comply with the requirement of this traffic code, unless the contrary shall be established by competent evidence.
(F) County Commissioners to designate crosswalks. The Board of Commissioners is hereby authorized to designate and maintain, by appropriate devices, marks or lines upon the surface of the roadway, crosswalks at intersections, where in its opinion, there is particular danger to pedestrians crossing the roadway, and at such other places as it may deem necessary.
(G) Traffic lanes. The County Commissioners are hereby authorized to mark traffic lanes upon the roadway of any road or highway under the jurisdiction of the county.
