Road Works Ahead Sign
Shape: Equilateral triangle (pointing up) · Colour: Yellow/white with red border
Road construction or maintenance work is in progress ahead.
What It Means
Road works create multiple hazards: uneven surfaces, lane narrowing, temporary diversions, construction equipment crossing the road, and workers present at the road edge. Reduced speed limits always apply in active road works zones in India (typically 40–50 km/h). Construction equipment operators may not see your vehicle approaching at speed. Road works zones are also associated with sudden lane shifts that can catch drivers off guard.
📍 Where You'll See It
Before and through road construction sites, pothole repair zones, bridge construction, and utility laying work across roads.
✅ What You Must Do
Reduce speed to the posted works-zone limit. Watch for workers, equipment, and temporary lane markings. Follow flagmen or marshals if present.
⚠️ Common Mistake
Maintaining normal road speed because the workers "look like they're at the side" — equipment and workers routinely cross the active lane.
⚖️ Legal Note
Speeding in a road works zone causing injury to a worker: Sec. 304A IPC/BNS (negligent act). Enhanced civil liability.
