(A) The driver of any vehicle shall obey the directions of any official traffic control device placed in accordance with the traffic ordinances of the town, subject to certain exemptions which are granted the driver of an authorized emergency vehicle in § 70.19, unless either is otherwise directed by a police officer.
(B) No provision of this traffic code which provides for signs shall be enforced against an alleged violator if, at the time and place of the alleged violations, the official sign is not in proper position or is insufficiently legible to an ordinarily observant person. Whenever a particular ordinance section does not stipulate signs, the section shall be effective without signs being placed to give notice thereof.
(Prior Code, § 9.3.01)
