Hairpin Bend Left Sign
Shape: Equilateral triangle (pointing up) · Colour: Yellow/white with red border
An extreme left U-shaped bend lies ahead.
What It Means
A left hairpin bend on Indian mountain roads presents the same extreme risk as a right hairpin, with the added challenge that the inside of the curve (the right side) has the cliff face, making it tempting to cut across the centre line to avoid the steep outer drop. On a left hairpin, the outer edge is the drop side. The natural tendency to "stay away from the drop" can push a vehicle into the oncoming lane.
📍 Where You'll See It
On ghat sections and mountain road zigzags — typically signposted well in advance.
✅ What You Must Do
Reduce speed dramatically. Stay in your lane even if the outer edge looks intimidating. Sound horn before blind sections. In mist or rain, speed must be near walking pace.
⚠️ Common Mistake
Drifting to the inside (right side) of a left hairpin to avoid the drop — this crosses the centre line directly into oncoming traffic.
⚖️ Legal Note
Accidents at hairpin bends in mountain areas frequently result in Sec. 304A (culpable homicide not amounting to murder) charges when speed was a factor.
