Table only as guideline, if space doesn't permit then a smaller sign may be used, however if accident record justifies it a larger sign may be used, however supplement plate must match size.

Other Requirements

  • Must have supplement plate 502 or 503 present with the distance in yards.
  • If at dual carriageway it may have an additional "dual carriageway" plate below the 502/503 plate.
  • May be accompanied by diagram 1024 (SLOW) on the carriageway
  • Must be lit during hours of darkness if on a lit street (<50m from lighting system, not applicable to 20MPH zone)

Pre-Worboys sign

There was not a specific advance warning sign of a stop or give way sign prior to 1964, although the regulatory "Halt/Slow major road ahead" signs were sited in advance of the junction, rather than at the stop/give way line.

Junctions were often warned of in advance using the T junction sign.

Worboys report sign

The sign (diagram 501) introduced in 1964 is an inverted warning triangle (i.e. one with the vertical point at the bottom) like the give way sign (diagram 602), with the difference that the white area within the red border is blank. This sign is always supplemented by diagram 502 "STOP" or diagram 503 "GIVE WAY" text plates with a distance to the junction in yards.

Republic of Ireland

Sign W 016 :
T-junction (Major Road) Ahead

In almost all cases in the Republic of Ireland, warning of an imminent junction with a major road – at which it will be necessary to either stop or yield – is given by means of a standard yellow-diamond warning sign bearing the appropriate diagram for the layout of the junction concerned (crossroads, T-junction, etc.), the thicker line indicating the major road, as shown in the accompanying image.

Stop Ahead and Yield Ahead signs – for exceptional use before junctions with very restricted advance visibility – are, however, provided for in the Irish Traffic Signs Manual. They consist of the standard Stop or Yield signs minus the words STOP or YIELD (i.e. a blank red octagon or an empty downward-pointing red-bordered white triangle), mounted above a supplementary plate stating the distance to the junction. (Images to be added later)
