Sec. 24-31. Obedience and presumption.


(a) The driver of any vehicle shall obey the instructions of any traffic-control device applicable thereto placed in accordance with the provisions of this chapter, unless otherwise directed by a law enforcement officer, subject to the exceptions granted the driver of an authorized emergency vehicle in this chapter.


(b) No provision of this chapter for which 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 a reasonably observant person. Whenever any section of this chapter does not state that traffic-control devices are required, such section shall be effective even though no devices are erected or in place.


(c) Whenever traffic-control devices are placed in position approximately conforming to the requirements of this chapter, 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.
