The High Vehicle symbol, Symbol F 50, is available for this. It is 30 stroke widths high. The first High Vehicle Advance Direction Sign should be placed directly after the Low Headroom Warning Sign (W 110) but at an adequate distance so the sign can be read. High Vehicle Advance Direction Signs F 500, F 501L or F 501R should then be provided in advance of decision points along the alternative route, to indicate whether high vehicles should continue straight ahead
or turn left or right. These signs should be mounted with other advance direction signs provided on the approaches to junctions along the route. The High Vehicle Direction Signs F 502L or F 502R,
should be used at relevant junctions, pointing either left or right to confirm the direction of the alternative route if it varies from straight ahead.
