Minimum Speed 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 travel at or above the posted minimum speed on this road.

What It Means

The minimum speed sign (a circle with blue background showing a number) is the opposite of a maximum speed sign. It requires vehicles to maintain at least the posted speed. This is common on expressways where very slow-moving vehicles — cycles, bullock carts, tractors — would create dangerous speed differentials with fast traffic. It also applies in tunnels where stopping creates suffocation and fire risk.

📍 Where You'll See It

On expressways, highway tunnels, elevated roads, and high-speed flyovers where slow vehicles would be dangerous.

What You Must Do

Maintain at least the minimum posted speed. If your vehicle cannot do so safely, do not enter the road.

⚠️ Common Mistake

Driving slowly on an expressway because it "feels" safer — a slow vehicle on a fast road is one of the most dangerous situations in traffic.

⚖️ Legal Note

Violation: Sec. 119 / 177 MV Act. Fine: ₹500.
