a footpath is for the sole use of people on foot, use of any other vehicle is illegal, I am not on about paths on private land but public right of ways.
A right of way is deemed to be one from an historical point of (Drovers roads ect) or by legislation, they all have categories, footpath, bridleway, B.O.A.T. (by open to all traffic), but like I said these may have changed, there were one or two others I think, but the principle is the same, and for reference all these are open to pedestrians expect motorways or where there are exceptions as in certain dual carriageways usually urban ones.
I know. On a public footpath, a right of way, as opposed to a footway by a road, cycling is illegal under the civil law, as opposed to the criminal law. The difference is that you can be fined for riding on a footway (i.e.a pavement by a road); you cannot be fined for riding on a public footpath because no criminal offence is committed - only a civil tort of trespass.
