⚠️ Road Narrows on Right Sign – Diagram 517 | Permanent UK Traffic Sign

It is an official UK warning sign used to alert drivers that the road ahead will narrow from the right-hand side. This sign is crucial for road safety and traffic management, ensuring that motorists reduce speed, adjust their position on the road, and prepare for a potential reduction in lane width.

📍 Where is the Road Narrows on Right Sign Used?

This sign is positioned in locations where lane narrowing on the right-hand side could impact traffic flow and safety:

  • Rural roads with natural obstructions reducing road width.
