FIELD: physics; construction.
SUBSTANCE: structure of the road sign consists of shields with an adjustable protective case made from metal or plastic with opaque walls. Inside the case there are optical fibre elements, tied to a shield by one end through open-end holes drilled in it. The holes are on an information character contour. The optical fibre elements are C-shaped and are tied to the shield in the same way as other ends with provision for retroreflective effect. There are extra holes on the character contour, and their diameter corresponds to the diameter of the optical fibre elements.
EFFECT: safer road traffic under difficult weather-climate conditions.
