All traffic signs placed on a highway or on a road to which the public has access (right of passage in Scotland), as defined in section 142 of the Road Traffic Regulation Act 1984 and amended by the New Roads and Street Works Act 1991, must be either prescribed by Regulations or authorised by the Secretary of State for Transport (for installations in England), the Department for Regional Development(Northern Ireland), the Scottish Executive or the Welsh Assembly Government as appropriate.
Neither the above sign or the two/three below are prescribed by regulations or authorised by the Secretary of State for Transport and are on a road to which the public has access as such I have register a complaint with Lincolnshire County Council requesting their removal at the earliest opportunity.
The Marsh Yard/Lincolnshire County Council sign, as per the regulations, should be a brown sign. But it can only be erected if the height barrier is removed as brown signs can only be erected for tourist attractions which are fully open to the public. Marsh Yard is not open to high sided vehicles and thus not fully open to the public.
Until Lincolnshire County Council revoke the byelaw and remove the height barriers I will continue my investigations into illegal road signs. Each sign costs up to £500 to make and install. To date my guesstimate is that I have identified 20 illegal signs a total of £10,000.
