LANE DESTINATIONS
13.4 Worded lane destinations (diagram 1035, see figure 13.2) reinforcing the information shown on the advance direction signs may be marked on the carriageway on the approach to junctions. These will normally be used with lane destination arrows, although the latter may be omitted. In confirming which lane to use, the markings provide drivers with an alternative indication to the advance direction sign in the event of it being obscured by high vehicles. Although abbreviations may be used, these must be understandable not only to local drivers, but also to those unfamiliar with the area. Abbreviations on the signs must be recognisable as the same destinations as those on the road, where fewer letters might need to be used.
13.5 Two sizes are prescribed for the legend, 1600 mm and 2800 mm. The smaller size is intended to be used when the speed limit is 40 mph or less, and the larger when it is more than 40 mph.
