Sec. 18-26. Signs as prerequisite to enforcement.
   No provisions of this chapter for which signs are required shall be enforced against an alleged violator if, at the time and place of the alleged violation, an official sign is not in proper position and sufficiently legible to an ordinarily observant person. Whenever any particular section in this chapter does not state that signs are required, such section shall be effective without signs being placed to give notice thereof.
