SECTION 1535.335 LOCATION OF SIGNALS
Section 1535.335 Location of Signals
a) For two directional traffic, one signal is to be located upon each side of the track or groups of tracks except that, where local conditions so require, a greater number of signals or flashing light units may be employed. The signals shall be placed on the right hand side of the highway as viewed by a traveler approaching the crossing unless local conditions require different arrangement. The distance from the signals to the railroad and to the edge of the pavement will be governed by local conditions, but in general the signals shall be located not more than 15 feet from the near rail except where a point in the centerline of the highway opposite the signal would be less than 10 feet therefrom. In general, the signals shall be located not less than 8˝ feet from the nearest rail. The distance from the signals to the edge of pavement shall not be less than 6 feet or more than 12 feet except when the pavement has curb and guttering, then the signals may be located 4 feet 1 inch but not less from the face of curb. These distances are to the center of the mast.
b) On multilane highways extending on either side of a median strip at least 8 feet 2 inches in width one additional flashing unit as shown in Figure 5 (Appendix B, Illustration E) shall be placed on each side of track or group of tracks, in such a manner as to provide appropriate warning to vehicles approaching crossing in traffic lane on left side of pavement. Back lights shall not be required.
c) Unless otherwise ordered by the Commission, on highways four or more lanes in width with no additional flashing units as set forth in Section 1535.335(b), supplemental sets of flashing light signals shall be mounted on appropriate cantilever arms (Figure 6 (Appendix B, Illustration F)) in such a manner as to provide appropriate warning to vehicles using the outer lanes. Back lights shall also be required.
d) Where conditions require, special signals such as side lights, illuminated "no left turn" and "no right turn" signs may be installed.
