W 183 Barrier Board – 3 Bars
Where a traffic lane is closed, Signs W 183, W 184 or W 185, Barrier Board, may be used.
This sign will normally be used at roadworks, in conjunction with cones and other traffic management measures. However, the signs may be used as a permanent installation to indicate the actual end of a lane or hard shoulder.
They are intended to supplement the other warning signs.
