New Delhi: Delhi government's odd-even scheme has come into implementation from 8 am on Monday (November 4) with chief minister Arvind Kejriwal urging all citizens to use carpooling to control the deteriorating air quality in the national capital.

A flagship scheme of the Aam Aadmi Party(AAP)-led Delhi government, the odd-even plan is a car rationing system aimed at combating pollution, by allowing cars with odd and even number plates to ply on the roads of the national capital on alternate days.

The scheme which has started from today will go on till November 14 and will be applicable from 8 am to 8 pm. It will not be valid on Sunday, November 10.

As it is starting today (November 4 - four being an even number), the cars with even numbers will be allowed on the roads for the day, till 8 pm.

The car rationing scheme comes at a time when the national capital region is battling with severe to very severe level of air pollution.

Urging citizens to follow the scheme, Delhi CM Kejriwal wrote on Twitter, "Hello Delhi, the odd-even scheme is starting today, in order to reduce air pollution. Do follow odd-even for the sake of your health, your children's health and your family's breath. Share car, this will help increase friendship, build relationships, save petrol and reduce pollution." He tweeted this in Hindi.

On October 17, Kejriwal had said that the odd-even vehicle rationing scheme would only be implemented on "non-transport four-wheeled vehicles", exempting two-wheelers and emergency vehicles.

Persons with disabilities, vehicles carrying school students and electric vehicles are exempted from the rationing scheme. However, this time, private CNG vehicles will come under its ambit. Delhi government has also said that only those women drivers who will steer the vehicle alone or with other women on-board or with a child less than 12 years of age will be exempted.
