Slippery Road quick-fit sign face - Diagram 557
The Slippery Road sign face warns drivers of reduced traction, showing a car losing control on a slippery surface caused by temporary works or weather. It is a face-only board that drops into a quick-fit frame, printed on RA1 Class 1 engineering-grade reflective on a 3mm plastic backing, and conforms to Chapter 8 and The Red Book. It is usually set out with a supplementary plate showing how far the hazard runs, and frames are sold separately.
