Delhi on Sunday introduced a toll for all trucks and commercial vehicles in an attempt to improve air quality in the world's most polluted capital ahead of Diwali celebrations.
Trucks are banned from entering the Indian capital during the day, but every night after 8pm more than 50,000 pour in, according to the Delhi-based Centre for Science and Environment (CSE).
The independent centre says lorries account for nearly a third of the pollution in Delhi, adding to a toxic mix of industrial fumes and dust from construction sites to produce hazardous levels of smog.
Last month, India's Supreme Court approved a four-month trial plan to charge light commercial vehicles an extra Rs 700 ($11) and large trucks Rs 1,300 to enter Delhi.
"The legal principle on which this charge has been levied is the principle of 'polluter pays'," Supreme Court lawyer Harish Salve, whose petition prompted the October 12 order, told AFP.
Successive Delhi governments have faced flak for failing to curb pollution in the Indian capital, whose air quality is worse than even Beijing's.
A World Health Organization study of 1,600 cities released last year showed Delhi had the world's highest annual average concentration of small airborne particles known as PM 2.5.
These fine particles of less than 2.5 micrometres in diameter are linked to higher rates of chronic bronchitis, lung cancer and heart disease as they settle into the lungs and can pass into the bloodstream. Many trucks transit through Delhi only to avoid paying tolls outside the city, and authorities hope the new toll will encourage drivers to use alternative routes.
