Byways!

So following on the "rights of way" discussion but on a cloudier day today. Both ways on this sign indicate a Public Byway and the notice expalins that it's open to all traffic so long as its "road legal". I rather like the horse and carriage! But see also the other notices that there is a public footpath ( brown arrow: a legal right of way) and also a "permissable horseride" (blue arrow: where this use is allowed by the landowner but there is no legal right of access)
