Unguarded Railway Crossing
These signs are used on approaches of railway level crossings where there are no gates or other barriers. A pair of signs are used for the purpose: (i) an advance warning sign located at 200m away from the crossing, and (ii) a second warning sign near the crossing (50-100m in plain and rolling terrain and 30-60m in hilly terrain).
Guarded Railway Crossing
These signs are used to warn traffic on the approaches to guarded railway crossings. A pair of signs are used for the purpose: (i) an advance warning sign located at 200m away from the crossing, and (ii) a second warning sign near the crossing (50-100m in plain and rolling terrain and 30-60m in hilly terrain).
Chevron (Single, Double, and Triple)
At the curved alignment of a roadway, the chevron signs are used to inform you about the sharpness of the curve. They are installed on the outside of a turn or curve to provide you with adequate time to react to the change in alignment. Depending upon the sharpness of the curve, Single Chevron, Double Chevron, and Triple Chevron signs are installed.
Hazard Marker (Left side, Right side, Two-Hazard Marker)
Roadside hazards like bridges, trees, etc. which are coming in the roadway are illuminated by retro-reflective Object Hazard Markers (OHM). Left side hazard marker is used for left side hazard so that traffic is allowed to pass from the other side (right side), while right side hazard marker is used for right side hazard so that traffic is allowed to pass from the other side (left side). Two-hazard marker is used if traffic is allowed to pass on either side of any triangular island/ hazard.
