Mexico City orders all cars off the road one day a week to tackle air pollution

In addition, vehicles must stay off the road one Saturday a month as the Mexican capital grapples with its worst air-quality crisis in over a decade

Authorities in Mexico City have temporarily ordered all cars to remain idle one day a week in response to this notoriously smoggy capital's worst air-quality crisis in over a decade.

Until now vehicles have been exempt from the Mexican capital's "no circulation" rules if owners obtain a holographic sticker from a smog-check centre certifying them as lower-emission.
