What It Means
The No U-Turn sign is critical on high-speed roads and divided highways where a vehicle turning back against traffic flow creates severe collision risk. U-turns require significant road width and time — on busy roads, the gap in traffic needed is rarely available safely. Illegal U-turns are a major cause of broadside and head-on crashes in India.
📍 Where You'll See It
On busy arterial roads, expressways, undivided highways near curves or crests, near signals, and in designated one-way zones.
✅ What You Must Do
Continue to the next legal U-turn point or intersection. Plan your route to avoid needing a U-turn.
⚠️ Common Mistake
Making a U-turn when no traffic is "visible" — other vehicles approaching from a distance or cresting a hill cannot see a turning vehicle in time.
⚖️ Legal Note
Violation: Sec. 119 / 177 MV Act. Fine: ₹500. If the U-turn caused an obstruction or accident: Sec. 184, fine up to ₹5,000.
