Diagram 645 – End of Restriction or Prohibition Sign

The Diagram 645 sign is an essential road safety feature in the UK, indicating the end of a restriction or prohibition imposed by an associated sign. This regulatory sign ensures clear communication to drivers, cyclists, and pedestrians that any prior restrictions—such as speed limits, parking prohibitions, or lane usage—are no longer in effect.

Manufactured to highway standards, this sign is a critical part of traffic management, ensuring road users receive clear guidance. Whether used in urban, rural, or motorway environments, it helps maintain efficient traffic flow and prevents unnecessary confusion on the roads.

When restrictions are in place, road users must adjust their behaviour accordingly to ensure compliance with UK road laws. The End of Restriction or Prohibition sign provides a clear indication that such adjustments are no longer necessary. This helps to improve the flow of traffic, reduce congestion, and enhance overall road safety.

This sign is particularly important in areas where traffic management strategies require temporary or permanent restrictions. These may include construction zones, controlled parking areas, or dedicated bus and cycle lanes. The removal of restrictions is as significant as their implementation, ensuring road users are aware when they can resume normal operation.

The Diagram 645 sign is an essential addition to any road network where temporary or permanent restrictions are implemented. Without this sign, confusion may arise, leading to potential safety risks, traffic congestion, and even legal infractions.
