Note: This sign is meant to be used where the road is structurally sound, but environmental issues cause the restriction eg. An estate in a town, where HGVs shouldn't use the road as a cut-through. If the road is unsuitable, structurally, then the sign to diagram Diagram 626.2A (Vehicles exceeding the maximum gross weight indicated prohibited) must be used.

Pre-Worboys Sign

There wasn't a Pre-Worboys Sign, but there would've been a worded sign, describing the restrictions.

Worboys Report Sign

The 1964 version of this sign contains a lorry symbol that consists of a van-like shape, with no restrictions on the side. The restriction is on a separate plate underneath the sign.

After the Worboys Report there have been a numerous changes of displaying the restrictions and what units to measure them in. Below is a timeline of all sign's revisions:


Modern Sign

The modern sign has a more "realistic" lorry Symbol with the weight in tonnes, shown by a lower case "t". The permitted variations are "7.5t" or "18t" according to Traffic Signs Manual: Chapter 3.
