Narrow Road Ahead Sign
Shape: Equilateral triangle (pointing up) · Colour: Yellow/white with red border
The road narrows significantly ahead — from both sides. Reduced width for the oncoming stretch.
What It Means
This sign warns of a section where the road width reduces — often at a bridge, underpass, or where construction has narrowed the carriageway. The narrowing may prevent two vehicles from passing side by side at normal speed. In India, many rural roads suddenly narrow at culverts or where the embankment has eroded, making this sign critical for highway drivers.
📍 Where You'll See It
Before narrow bridges, culverts, underpasses, and road sections where the carriageway width drops below normal.
✅ What You Must Do
Reduce speed. Move towards your side of the road. If oncoming traffic is present, one vehicle may need to slow and pull slightly off the road to allow passage.
⚠️ Common Mistake
Assuming the other vehicle will slow down. Both vehicles should slow; do not accelerate through a narrow section.
⚖️ Legal Note
No specific sign violation, but driving dangerously through a narrow section causing an accident attracts Sec. 184 MV Act.
