 The sign to diagram 637.1(prohibition of waiting on the verge or footway, see para 6.10) is used without a road marking and therefore the first and last sign indicating where the prohibition starts and finishes should normally include an arrow. In village locations where a verge is being protected from parked vehicles, the start and end might be obvious and arrows might not be necessary. Intermediate signs should be provided as appropriate. In most cases, including rural roads subject to the national speed limit, signs should be provided at approximately 30 m intervals. This spacing is the same as for waiting restriction signs in pedestrian zones (see para 11.19) and restricted zones (see para 13.8) where there are no yellow lines to draw attention to the prohibition. 53
