Keep Left Sign
Shape: Circular (octagonal for Stop, inverted triangle for Give Way) · Colour: White with red border (prohibitory); blue with white symbol (positive mandatory, e.g. compulsory turn, keep left)
Vehicles must stay to the left side of the road or obstruction ahead.
What It Means
India follows left-hand traffic, meaning all vehicles travel on the left side of the road. The Keep Left sign reinforces this — specifically placed where an obstruction, median opening, or road feature might tempt drivers to move right. It is also used at roundabouts and on roads with a central obstruction or island that vehicles must pass on the left side.
📍 Where You'll See It
At median gaps, central islands, roundabout entrances, and on roads with central obstructions like dividers, trees, or bollards.
✅ What You Must Do
Pass the obstruction or stay on the left side as directed. Do not attempt to pass on the right of any obstacle marked with this sign.
⚠️ Common Mistake
Passing on the right side of a traffic island when Keep Left is posted, which puts you directly into oncoming traffic.
⚖️ Legal Note
Violation: Sec. 119 / 177 MV Act. Fine: ₹500.
