Consultation on the positioning of speed limit signs near Junctions 3 and 4

Highways England is consulting on a proposed amendment to the M4 Motorway (Hillingdon and Hounslow) (Speed Limits) Regulations 2002 No.1651.

The M4 junctions 3 to 12 smart motorway scheme involves the use of variable mandatory speed limits (VMSL) displayed on signals installed on overhead gantries – this will lead to a change in the location where the 60mph speed limit starts (currently shown by a fixed plate sign) between junction 4 and junction 3 eastbound.

VMSL gantries will displace the current 60mph fixed plate signs and a gantry cannot be sited at the current starting point of the 60mph limit due to the terms of the M4 Motorway (Junctions 3 to 12) (Smart Motorway) Development Consent Order 2016. 

An amendment is required for this change and the consultation is related to this amendment only. You can find out more about the proposals in the link below, along with details on how to respond to the consultation.
