They should be placed directly in the sight line of approaching drivers. Signs W 062 and W 063, Multiple Chevrons, should be used:1.On roundabout islands, other than at mini roundabouts, to face traffic on all approaches. The Chevron is used at roundabouts in conjunction with a Keep Left sign (RUS 006). 2. At a rural T-junction where the major road turns through a sharp angle. 3.To supplement a Sharp Bend or Corner sign (Signs W 050 to W 053) which on its own does not provide sufficient warning.4.At other sharp changes of direction where, in the opinion of the Road Authority, the road layout is deceptive, not obvious to approaching drivers and constitutes a potential hazard. 5.As a temporary measure at roadworks, to aid delineation of the site.
