In most instances they illustrate the principal through route at the junction by varying the widths of the road symbol arms. The signs are not intended to be true maps of the junction, but the sign selected should be reasonably representative of the layout. The roads of lesser importance are indicated on the signs by arms of narrow width. Stop or Yield signs or markings will normally control traffic on the side
roads. Signs W 001 to W 014 are available for use on the major road approaches to junctions.
