Ice' Supplementary Plate - Post Mount Dia. 554.3 R2/RA2
The Ice supplementary plate is a permanent sign that gives drivers warning that there is a high likelihood of ice on the road ahead. When installed alongside sign face 554.2 it gives a clear warning to drivers that extra care should be taken in case of loss of traction.
This sign should never be used on its own and should only ever supplement sign faces 554.2, 622.1A, 622.4, 629A, 629.1 or 632.
The size of the text on this sign can be adjusted to suit the installation location requirements. For full guidance on the proper sizing of this sign, and where it should be used it is important to consult the TSRGD guidelines, links to which can be found on our regulations page.
