Traffic Under Signal Control Sign QuickFit EnduraSign Dia 7021 1050x750mm square chart step template for infographic for presentation for 8. Our Traffic Under Signal Control 7021 QuickFit EnduraSign is ideal for setting out on junctions where a sideroad is joining onto a route that is currently under signal control. This sign lets drivers know that they should expect traffic to be flowing potentially from the wrong direction on the incorrect side of the road and that they should proceed with caution. This temporary road traffic sign comes complete with both the sign face and the high quality stand. The sign face is 1050mm x 750mm and features an RA1 reflective face, allowing it to be seen in the dark with ease. The stand has toggles at 300mm centres allowing all small form factor quick fit signs with the same hole centres to be used and interchanged freely. This traffic management sign can be used on public roads so long as it is done so in accordance with guidelines set out in Chapter 8 of the Traffic Signs Manual, links to this and the Red Book can be found on our Regulations page.
