n UK traffic signing, diagram 502 is the “STOP” distance plate used beneath diagram 501 to tell drivers that a STOP sign and stop line are ahead, usually with the distance shown in yards. It is used where the STOP junction is not visible soon enough on approach, so drivers need earlier warning to slow down and prepare to stop safely; the Traffic Signs Manual says diagram 501 should be used with a plate to diagram 502 where visibility of the STOP sign is below the recommended standard.
Specification:
Material: R2/RA2 reflective overlay on aluminium composite backing
Fixing Method: 2 fixing rails for post mounting
Reflectivity: Class 2 R2/RA2
As per the UK Highways Traffic Sign Manual Chapter 4 page: 15 The following advice is given:
2.1.1. The sign to diagram 501 (S2‑6‑1, see Figure 2-1) should be used where the clear visibility distance (see 1.9.3 and 1.9.4) to the STOP or GIVE WAY sign is less than the distance given in Table 2-1. The sign may also be accompanied by the word SLOW (diagram 1024) marked on the carriageway. Where the junction is with a dual carriageway road, the “Dual carriageway” plate remains below the STOP or GIVE WAY plate (see also 5.6). Where there is a gap in the central reservation and a right turn is permitted, this should reduce the risk of drivers turning into the wrong carriageway. See Chapter 3 for further guidance on the STOP and GIVE WAY signs, and Chapter 5 for road markings at junctions. 501 Junction ahead controlled by a GIVE WAY sign 501 Junction ahead controlled by a STOP sign Diagram 501 supplementary plates may not be used alone. The distance plate must always be used and may be varied. The “Dual carriageway” supplementary plate may be omitted. Figure 2-1 Diagram 501 (S2‑6‑1) Junction ahead controlled by GIVE WAY / STOP
