At first, it was only applied to small and medium-sized towns, like Cesena and Olbia. But then, finally, the 30 km/h speed limit spread like wildfire to many large Italian cities—Bologna, Milan, Turin, Rome, to name just a few. And the results are visible: fatal accidents and wasted human lives decrease, and the level of pollution in the areas affected by the provision. But let's see which are the most important Italian cities that have introduced the 30 km/h speed limit and how.

 

  • Bologna. The project is called City 30 and covers almost 90 percent of the municipal territory, leaving space and safety for cyclists and pedestrians. The clear and evident results are contained in these numbers: in 2024, deaths fromroad accidents in the urban area of ​​Bologna are decreased, compared to the previous two years, by 49 percent; Serious accidents dropped by 31 percent; total accidents by 13,1 percent. And for the first time in decades, no pedestrians were killed. 
  • Milan. The Lombardy capital has implemented a 30 km/h speed limit on over a hundred streets, especially those used for residential traffic, to promote safer mobility for pedestrians, cyclists, and vulnerable road users.
  • Turin.  Some neighborhoods are completely 30 km away, even though speed limit measures have always been highly controversial, in a city that by history and tradition is closely tied to car use. The 30 kilometre speed limit, which has also helped reduce fatal accidents and wasted lives in Turin, is in place on all roads in the ZTL zone, and in some important neighborhoods such as Vanchiglia San Salvario.
  • Rome. Although significantly delayed, 52 roads have been identified in Rome, both in the city center and in the more peripheral areas, where speeds of more than 30 kilometers per hour are prohibited.
  • Naples. Here, unfortunately, the 30-kilometer limit is only in place on some streets in the historic center, which are always very crowded and busy.
  • Trieste. The 30 km/h speed limit is in place in several areas of the city, where speeds were usually very high, posing a danger to pedestrians, cyclists, and motorists themselves.
  • Florence. In neighborhoods where the streets have a maximum speed of 30 kilometers per hour, still few, signs reading “Zona 30” are clearly visible.
