Paris speed limit: City slams on the brakes with 30km/hr rule

Paris(CNN) Authorities in the French capital of Paris are forcing drivers to slow down, setting a speed limit on almost all the city’s roads, in a bid to reduce pollution and improve road safety.

But will it work? There are questions over whether the rule — which limits drivers to 30 kilometers per hour (19 miles per hour) — will actually reduce pollution. Some critics say it will worsen the city’s rush-hour traffic jams and could even increase greenhouse gas emissions.

That will depend partly on whether drivers get so fed up with the speed limit that they choose to commute in other ways.

To further dissuade drivers from taking vehicles into the city, authorities are also getting rid of 60,000 of the Paris’ 144,000 parking spaces on public roads to make them “more accessible to everyone,” and will better utilize underground parking. Some sidewalks will be widened — allowing more walking space, as well as trees and plants — and new cycle lanes will be installed.

According to a poll by the Parisian City Hall, 59% of the city’s residents were in favor of the new limit, which came into effect on Monday, but opposition was much higher in the wider Île-de-France region, at 61%.

A delivery driver stuck in traffic on Monday said that the change had been “terrible.”

“With deliveries, it’s terrible. We don’t have time. I was in traffic jams everywhere. We don’t have time,” he told CNN affiliate BFMTV, which did not name him.

Another driver said it was as if car drivers were traveling on “electric scooters,” calling the rule “crazy.”
