Compulsory Ahead Only 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 proceed straight ahead. Turning left or right is prohibited.
What It Means
This sign requires all vehicles to continue in a straight-ahead direction. It is placed at intersections or junction entries where turning would create dangerous conflicts — often on divided roads where a turn would take you into oncoming traffic, or at traffic management points designed to maintain a specific flow direction.
📍 Where You'll See It
At certain T-junctions approached from the stem, on divided roads near median gaps, and at specially controlled intersections.
✅ What You Must Do
Continue straight ahead. Do not turn into any side road or take any exit at this point.
⚠️ Common Mistake
Turning into what appears to be a clear side road when an Ahead Only sign is posted.
⚖️ Legal Note
Violation: Sec. 119 / 177 MV Act. Fine: ₹500.
