Carpool Lane On Paris Ring Road Becomes Active

PARIS, FRANCE - MARCH 6: A sign indicating that the left lane is reserved for carpools, buses, cabs, emergency vehicles and people with reduced mobility stands next to the ring road on March 6, 2025 in Paris, France. On Monday, Paris began restricting one lane of its ring road (one of Europe's most congested arteries) to carpooling during rush hour. This is the latest measure taken by the French capital to reduce traffic congestion and air pollution. (Footage by Vincent Isore/IP3/Getty Images)
