Diesel ban will last as long as there is high air pollution. Eventhough it is a two-day practice, it is expected to be extended after Wednesday.
The ban applies to all diesel-powered vehicles with some exceptions. The exceptions include emergency vehicles, plug-in hybrid-diesel vehicles, vehicles used in public service, patient transport, transit and vehicles used for commercial purposes.
