asked Her Majesty's Government:

What plans they have to reduce the size of the road traffic signs used to enforce the ban on motorised vehicles on routes such as The Ridgeway. [HL3042]

The Government have no plans to reduce the size of road traffic signs generally. Road traffic signs must either meet the requirements of the Traffic Signs Regulations and General Directions 2002, or be authorised by the Secretary of State. Signs indicating a prohibition of motor vehicles are already prescribed in a wide range of sizes. While signs should not be intrusive, they must be conspicuous in order to be effective.

Decisions about the placing of road traffic signs at particular locations are the responsibility of the relevant traffic authority. It would be for the authority to seek special authorisation, if it is considered that there are special circumstances that justify an exceptionally small sign. The merits of any such application would be considered on a case by case basis.
