     § 3111.  Obedience to traffic-control devices.
        (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.
