WK 073 Loose Chippings TM0204
The WK 073 Loose Chippings sign should be used to indicate that there is a risk of airborne chips or stones due to a surfacing operation being undertaken.
At the start of the relevant section of road, this sign may be erected with Supplementary Plate P 080, Slow, or P 011, Cautionary Speed.
Sign WK 073 with Supplementary Plate P 010, End, should be erected to mark the end of the section affected. However, if this coincides with the end of the roadworks, Sign WK 001 with Supplementary Plate P 010 should be erected instead.
