Italian traffic sign: unleaded fuel ahead. Introduced in 1992 as picture II 357 of Highway Code Regulations. Sign obsolete since directive n. 777 of 2006 that, despite never modifing Highway Code Regulations, suggested the exclusive use of sign II 356 for all kind of fuel station, considering the almost universal availability of unleaded fuel.
