Obviously parking on yellow lines is prohibited, and one should always parking in the direction of the Traffic , and not park in such away to impede the through flow of traffic or block vehicular access to parking with in the boundaries of a property, but what about on-street parking where there are NO yellow lines ?
Are there any laws (other than to deal with obstruction) which may prohibit parking in such places with no yellow lines?
Do property owners or occupiers have any proprietorial rights over the road in front of their premises and do these home made " no parking " signs otherwise have any legal validity ?
