Italian road sign: urban indication signs used as confirmation sign in urban roads. White background = urban destination (in the example a pedestrian zone and a cattle market), light gray background = direction for important road/square, yellow background = tourisitc destination (in the example a tourisitc marina). Note that the color order does not follow the prescription of the ministerial circular but seems random. Picture 137 of ministerial circular n. 400 of 1979.
