(a)  General rule.--Unless otherwise directed by a uniformed     police officer or any appropriately attired person authorized to     direct, control or regulate traffic, the driver of any vehicle     shall obey the instructions of any applicable official traffic-     control device placed or held in accordance with the provisions     of this title, subject to the privileges granted the driver of     an emergency vehicle in this title.        (b)  Proper position and legibility of device.--No provision     of this title 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,     the section shall be effective even though no devices are     erected or in place.        (c)  Presumption of authorized placement.--Whenever official     traffic-control devices are placed or held in position     approximately conforming to the requirements of this title, the     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.        (d)  Presumption of proper devices.--Any official traffic-     control device placed or held pursuant to the provisions of this     title and purporting to conform to the lawful requirements     pertaining to such devices shall be presumed to comply with the     requirements of this title, unless the contrary shall be     established by competent evidence.
