The system is designed to warn the drivers for the potential of the presence of an icy layer on the road.

It is consisted by a panel with a reflective warning traffic sign (slippery road), a set of yellow Led flashing lights and an electronic panel which displays the current temperature of the road surface.

A high precision temperature probe is inserted directly into the ground, so when the temperature falls under +3°C/37.5°F the Led lights start to flash in order to warn the drivers.

An SMS can be sent at a set temperature, in order to inform the relevant private or public services for the road condition.
