Traffic Under Signal Control Quick-Fit Sign Face - Diagram 7021
The Traffic Under Signal Control sign face warns drivers at an uncontrolled junction that the road they are joining is running under temporary traffic signals, so traffic may be flowing one way or stopping suddenly in single-lane working. Printed to diagram 7021 on Class 1 RA1 engineering grade prismatic sheeting with a 3mm plastic backing, it conforms to Chapter 8 and The Red Book. This listing is for the sign face only - quick-fit frames are sold separately.
