Cautionary Signs

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).
