Shubham, a commuter in New Delhi, has just been given a fine for an odd reason.
The number plate on his car does not end in an even number.
Authorities in the Indian capital have banned cars with number plates ending in an odd number from the roads in a bid to tackle the hazardous air pollution shrouding the city.
(SOUNDBITE) (Hindi) COMMUTER, SHUBHAM, SAYING: "I didn't know that the odd-even rule was starting from today.
I came to Delhi for some work last night and I was returning home.
When I saw the poster, I tried to escape quickly but I was caught.
I won't make this mistake from now on." A public health emergency has been declared and the city's government has imposed the odd-even system until November 15.
The U.S. embassy air quality index, which measures the concentration of tiny particles in the air, has exceeded 500.
That indicates serious aggravation of heart and lung disease and premature mortality in people with existing diseases and the elderly.
It also poses serious risks to the respiratory systems of the general population.
(SOUNDBITE) (Hindi) STAFF AT INDIRA GANDHI INTERNATIONAL AIRPORT, BHAIRON SINGH, SAYING: "The pollution in Delhi is very bad and here at the airport, we are facing difficulty breathing.
There's a burning sensation as if someone has put chilly in my eyes." Flights have been delayed or canceled at Indira Gandhi International airport and in Delhi's battle to breath, authorities have also shut schools and ordered all construction work to stop.
