🚦 # Diagram 672 – Minimum Speed Limit of 30 MPH # 🚗💨

A 30 mph minimum speed limit sign (Diagram 672) is a crucial part of the UK road system, ensuring that vehicles maintain a safe and steady speed in designated areas. Unlike speed limit signs that impose a maximum speed, this sign mandates a minimum speed of 30 mph, preventing slow-moving vehicles from disrupting traffic flow and causing potential hazards.

This sign is commonly placed on dual carriageways, tunnels, and high-speed roads where maintaining a steady pace is essential for overall traffic efficiency and safety.

🔥 Highly Visible Design for Maximum Impact

The Diagram 672 sign is designed for instant recognition with a bold white “30” numeral set against a bright blue circular background. The distinctive blue color signals an instruction rather than a restriction, making it easily distinguishable from red-bordered signs.

✅ Reflective RA1 or RA2 options – Enhances visibility in low-light conditions and bad weather.
✅ Clear, bold font – Ensures quick readability, reducing driver reaction time.
✅ Blue and white contrast – Conveys an unmistakable regulatory message to all road users.

With its highly reflective properties, the sign remains visible in all lighting conditions, making it effective even at night or during adverse weather.
