In a decisive move to address the alarming levels of air pollution plaguing the Indian capital, the Commission for Air Quality Management (CAQM) has activated Stage III of the Graded Response Action Plan (GRAP) in Delhi, effective immediately.

Beginning Friday, the Delhi Transport Department will implement stringent fines for vehicles that breach pollution standards, with violators facing hefty penalties of up to Rs 20,000.

Under the newly imposed regulations, specific categories of vehicles are now prohibited from operating within the city limits:

1. BS-III petrol and BS-IV diesel light motor vehicles (LMVs): This restriction targets older cars and four-wheelers registered in these categories, effectively barring them from the roads of Delhi.
2. BS-III diesel medium goods vehicles (MGVs): Vehicles registered in Delhi that fall under this category will be prohibited from circulation unless they are engaged in the transport of essential goods or services.
3. Diesel light commercial vehicles (LCVs) from outside Delhi: Vehicles adhering to BS-III standards or lower will face entry bans unless they are delivering essential commodities to the city.
4. Interstate buses from National Capital Region (NCR) states: Only electric, CNG, or BS-VI diesel buses are allowed access to Delhi, while those equipped with All India Tourist Permits are granted an exemption.

This comprehensive crackdown on pollution, enforceable under Section 194(1) of the Motor Vehicle Act, 1988, is strategically designed to mitigate the harmful emissions produced by older vehicles, which are known to be significant contributors to the city’s deteriorating air quality.

According to officials from Delhi’s Transport Department, these measures successfully balance the dual objectives of environmental preservation and the continuity of essential services. These critical restrictions highlight the pressing need for action to combat air pollution and promote public health throughout the city.
