2006 New York Code - Obedience To And Required Traffic-control Devices.

 
    § 1110. Obedience  to  and required traffic-control devices. (a) Every
  person shall obey  the  instructions  of  any  official  traffic-control
  device  applicable  to  him  placed in accordance with the provisions of
  this chapter, unless otherwise directed by a traffic or police  officer,
  subject  to the exceptions granted the driver of an authorized emergency
  vehicle in this title.
    (b) No provision of this title for which signs are required  shall  be
  enforced  against  an  alleged  violator if at the time and place of the
  alleged violation an  official  sign  is  not  in  proper  position  and
  sufficiently  legible  to  be  seen  by  an ordinarily observant person.
  Whenever a particular section does not state that  signs  are  required,
  such  section  shall be effective even though no signs are erected or in
  place.
    (c) Whenever official traffic-control devices are placed  in  position
  approximately  conforming  to  the  requirements  of  this chapter, such
  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)  Any  official  traffic-control  device  placed  pursuant  to  the
  provisions  of  this  chapter  and  purporting  to conform to the lawful
  requirements pertaining to such devices shall be presumed to comply with
  the  requirements  of  this  chapter,  unless  the  contrary  shall   be
  established by competent evidence.
    (e)  For  purposes  of  this article, "intersection" shall include the
  area embracing the juncture of a highway with a private road or driveway
  and "intersecting roadway" shall include an intersecting private road or
  driveway.
