Proposed by a citizens’ group called “Paris without cars” and taken up by the Socialist mayor of Paris, Anne Hidalgo, the ban will be enforced on most of the Champs-Elysées, areas around the Eiffel Tower, Montmartre, the Luxembourg gardens, the Canal Saint-Martin and central neighbourhoods bordering the Seine. Motorists in other parts of the city will have to observe a speed limit of 20 kilometres per hour (12 mph), as will drivers of electric cars.
