Written and checked bySignalPe Desk· Editorial Desk

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.
