These do exactly what they say on the tin. They are paths for feet. Only people (and any natural accompaniment) may use them.
A bridleway is a bonus for hikers because walkers can use them as well as cyclists and horse riders. However, even a detailed map won’t tell you about the cross-country biker just about to hit you as he comes around the next corner.

The acronym for Road Used as a Public Path. Technically, it is a road, and therefore motorised vehicles are permitted, although they are generally so poorly maintained that no sensible driver would consider taking a vehicle down them; the puddle-filled potholes would very effectively succeed in shafting your big end.
In practice, such routes tend only to be used by hikers, cyclists and horse riders, and since the Countryside and Rights of Way (CRoW) Act 2000, all remaining RUPPs were reclassified as restricted byways on 2 May 2006. A bluffer will boost his or her status by knowing what they are when they are spotted on signposts and waymarks (see ‘Close Encounters of the Herd Kind’, page 96), and will insist on referring to them by their former name.
