Editor’s note–Former § 82-51, Installation of traffic control devices, which derived from Code 1984, ch. 10, § 4(E), was repealed 5-14-2018 by Ord. No. 1350-18.
It is unlawful for any person other than the chief of police, acting pursuant to an ordinance of the city, to install or cause to be installed any signal, sign, or device purporting to direct the use of the streets or of the activities on those streets of pedestrians, vehicles, motor vehicles, or animals. Proof in any prosecution for a violation of this section, or any traffic regulation of the city that any traffic control device, sign, signal, or marking was actually in place on any street shall constitute prima facie evidence that such traffic control device, sign, signal, or marking was installed by the chief of police pursuant to the authority of this section and of the ordinance directing the installation of such device, signal or marking.
[Code 1984, ch. 10, § 4(F)]
All traffic-control signs, signal, device and markings that have been placed or erected and are in use for the purpose of regulating, warning or guiding traffic are hereby affirmed, ratified and declared to be official traffic-control devices.
[Ord. No. 1350-18, § 2, 5-14-2018]
All traffic-control devices and signals within the city shall be presumed valid and the existence thereof shall constitute prima facie proof of competent authority and lawful erection of such devices and signals. In any prosecution for any violation of law, it shall be necessary for the state to prove the installation or authority therefor of any traffic-control device or signal.
[Ord. No. 1350-18, § 2, 5-14-2018]
Any person charged with violating a law concerning a traffic-control device or signal shall have the right to rebut the presumption created in section 82-54 and to prove that such device or signal was erected unlawfully or without lawful authority.
