§ 1685. All  vehicles  must  stop  at certain railroad grade crossings
  where a stop sign is erected.  The  state  transportation  commissioner,
  with  respect  to  state highways, and local authorities with respect to
  local streets within their jurisdiction, with the approval of the  state
  transportation commissioner are hereby authorized to install a stop sign
  at any highway-railroad crossings within their respective jurisdictions.
    The  design  and  place and manner of installation of such signs shall
  conform to the manual and specifications for a uniform system of traffic
  control devices adopted by the state transportation commissioner.
    Whenever any such crossing  is  so  designated  and  a  stop  sign  is
  installed, it shall be unlawful for the driver of any vehicle to fail to
  stop within fifty feet but not less than fifteen feet from such railroad
  tracks  before  traversing  such  crossing. The failure to erect, or the
  erection of or failure to replace or maintain such signs shall not be  a
  basis  for  any action of negligence against a municipality or the state
  nor a basis of a defense by a railroad in an action based on  negligence
  against a railroad.
