29. Car-Free Sundays
In October 2018, Paris introduced the concept of car-free days on the first Sunday of each month. A plan for the program to be extended to one day per week throughout the entire city is under discussion. As of this writing, the program affects only the center city. During the car-free period, from 10 AM to 6 PM, noise levels in the city center drop by more than 3 decibels.
Following the success of the program in the city center, the first through the fourth arrondissements joined the program. Special dispensations for city residents, delivery vehicles, and others allow access through designated points with severely restricted speeds (20 kmph, or 12 mph).
