Question to the Department for Transport:
To ask the Secretary of State for Transport, for what reason the A316 from Junction 1 of the M3 to the Whitton Road roundabout has speed limits of 40mph and 50mph.
The M3 junction 1 is at the edge of the Greater London Authority boundary. The responsibility for managing London's road network is shared between Transport for London (TfL) and the London boroughs.
Local authorities have the power to set speed limits on their roads. They have the local knowledge making them the best placed to do so.
