Paris Introduces Carpool-Only Lanes on Périphérique to Combat Pollution

The experimental measure targets solo drivers and aims to reduce traffic congestion and air pollution in the French capital.

Starting March 3, the left lane of Paris's Périphérique is reserved for vehicles with at least two passengers, public transport, taxis, emergency vehicles, and those with mobility challenges during peak hours on weekdays.
The initiative, an extension of lanes used during the 2024 Olympics, seeks to address high pollution levels affecting 500,000 residents near the urban highway.
No fines will be issued until May 1, with a two-month educational phase using AI-based detection and warning messages for violators.
Critics, including opposition politicians and driver associations, fear increased congestion and inequity for solo drivers, citing insufficient impact studies.
Initial compliance with the new rules has been low, with reports of single-occupant vehicles frequently using the restricted lanes.
