Paris is taking drastic measures to combat its worst air pollution in years, banning around half of the city’s cars and trucks from its streets in an attempt to reduce the toxic smog that’s shrouded the City of Light for more than a week. Cars with even-numbered license plates are prohibited from driving in Paris and its suburbs Monday, following a government decision over the weekend. Around 700 police were patrolling the morning rush hour handing out tickets to offenders. Taxis and commercial vehicles aren’t covered by the ban. It was the first time since 1997 that the emergency measure was taken. If the pollution persists, odd-numbered vehicles will be banned on Tuesday. Public transport has been made free for a fourth day to help deal with the pollution.
