Chapter 14 MOTOR VEHICLES AND TRAFFIC*
Section 14-464 Official traffic control devices--When required for enforcement purposes.
No provisions of this chapter 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.
