Road signs, markings and traffic controlQuestion #14908
What does this supplementary plate indicate?
Explanation
Supplementary plate No. 848 “Icy road” is used with another sign (usually “Speed limit” or “Slippery road”) and means that sign applies only when the surface is icy or covered with snow.
KET reference: KET 1 pr. 848: Icy road. A stretch marked this way is often slippery because of ice or snow.
