Italian road sign: motorway location marker (type B). The number on white plate represents the km of the motorway. This model is used on motorway having the median of less than 3 m width and is used as an alternative to model B motorway location marker with green additional plate. In this case the green plate is omitted but when the last digit of the number is 0 a confirmation sign is placed on the right side of the motorway.
