The Road Commissioner shall determine and designate the size, shape and character of all official warning, regulatory, and direction signs, other than signs the size, shape and character of which have been established by the State Department of Transportation pursuant to the Vehicle Code.
(1) Violation. No provision of this Chapter for which signs are required, shall be enforced against an alleged violator thereof, unless appropriate signs are in place and sufficiently legible to be seen by an ordinarily observant person, giving notice of such provision.
(b) Authorization and Placing of Signals.
(1) The Board shall by resolution designate, upon the basis of a traffic engineering investigation, what intersections shall be controlled by official traffic control signals.
(2) Whenever the Board finds, upon the basis of a traffic engineering investigation, that the conditions, because of which traffic control signals have been placed at an intersection pursuant to § 52.0107(b), no longer exist, the Board shall by resolution direct that such traffic control signals be removed.
The Road Commissioner is hereby authorized to place, maintain, operate or remove, or cause to be placed, maintained, operated or removed, all official traffic control signals authorized by the Board as herein provided. Such official traffic signals shall conform to the provisions of the Vehicle Code.
(c) Hours of Operation.

(d) Installation by Road Commissioner.
(1) The Road Commissioner may place and maintain such traffic control devices in addition to those authorized by other provisions of this Chapter as may be necessary to regulate, guide or warn traffic, but the Road Commissioner shall make such determination upon the basis of traffic engineering principles and traffic investigations and in accordance with such standards, limitations and rules as may be established by ordinance or resolution of the Board.
(2) Whenever the Road Commissioner finds, upon the basis of a traffic engineering investigation, that the conditions, because of which such traffic control devices have been installed as provided in § 52.0107(d), no longer exist, the Road Commissioner shall remove such traffic control devices.
(e) Traffic Markings. The Road Commissioner is hereby authorized to place, upon the basis of a traffic engineering investigation, traffic guide lines, dividing highways into the number of traffic lanes that are proper and necessary, and may place such other pavement markings as are necessary to direct vehicular movements in accordance with requirements of this Chapter and the Vehicle Code.
Whenever the Road Commissioner finds, upon the basis of a traffic engineering investigation, that the conditions, because of which traffic guide lines or other markings were placed as provided in § 52.0101(e), no longer exist, the Road Commissioner shall remove such traffic guide lines or such markings.
(f) Temporary Removal. Whenever, because of the construction, alteration, repair or improvement of any highway, or because of other emergency, compliance with any prohibition of this Chapter, including a prohibition pursuant to any action of the Board taken in accordance with this Chapter, will create a traffic hazard and the Road Commissioner so finds, he or she is hereby authorized to either remove or cover up any traffic control device which informs persons of such prohibition. While such traffic control device is removed or covered, the effect of such prohibition is suspended. At the end of such emergency, unless otherwise determined by the Board, the Road Commissioner shall replace or uncover such traffic control device.
