Overview

• The Euro-5 diesel driving bans will take effect on October 1, 2025, across Piedmont, Lombardy, Emilia-Romagna, and Veneto, targeting municipalities with over 30,000 residents.
• Piedmont's restrictions will be seasonal, running from September 15 to April 15 on weekdays between 8:30 AM and 6:30 PM, starting in 2025.
• Lombardy will enforce year-round bans from 7:30 AM to 7:30 PM in major urban areas, including provincial capitals and towns with over 30,000 residents.
• Violators face a €168 fine, with repeat offenders risking higher penalties and a 15–30 day license suspension under Italian traffic law.
• Implementation challenges persist, including the lack of an environmental sticker system and the high number of affected vehicles, particularly in Piedmont, where 250,000 Euro-5 diesel cars are registered.
