Dangerous Dip Sign
Shape: Equilateral triangle (pointing up) · Colour: Yellow/white with red border
The road dips sharply ahead, limiting visibility and creating a vehicle-control hazard.
What It Means
A dangerous dip is a sharp valley in the road profile — the road drops and then rises again. Dips are hazardous because: oncoming vehicles can be hidden in the dip below your line of sight; water accumulates in dips during rain, sometimes to depths that can stall a vehicle; and vehicles can bottom out if the dip is severe. On high-speed roads, encountering a flash-flooded dip at speed can be fatal.
📍 Where You'll See It
On undulating rural roads, after bridges over dry riverbeds (which flood in monsoon), and at road crossings over nullah (drainage channels).
✅ What You Must Do
Slow down. Do not enter a flooded dip — "turn around, don't drown." Check for oncoming vehicles emerging from the dip before you start descending into it.
⚠️ Common Mistake
Driving through a flooded dip "because it looks shallow." Water depth is notoriously difficult to judge from a car, and even 30 cm of moving water can stall most cars.
⚖️ Legal Note
No specific violation for the sign, but entering a flooded road and needing rescue is an offence in some states (ignoring road closure orders).
