text: Paris enforced to ban driving to clear the air of the global city. Drivers would have to leave their cars at home if they had odd or even numbered license plates or pay a 22-euro fine. Car traffic decreased to 60 percent in the capital of France after five- days of intensifying smog. Exceptions were made for plug-in cars, hybirds, and cars carrying three or more passengers. Public transportation was free from Friday to Monday. Paris has more smog than other European capitals. The smog cleared enough Monday for the ruling French party to recind the ban for odd-numbered plates on Tuesday.
