GRAP 3 In Delhi Explained: What Is Banned, What Is Allowed

Delhi and its adjoining areas have been covered under a blanket of thick smog since last morning and the air quality has plummeted to the 'Severe' category and the air quality index reported over 400 in several areas.

The Commission for Air Quality Management (CAQM) had called the early-morning dense smog an "episodic event" and said they expect the situation to improve by today but the dangerous levels of AQI have forced the CAQM to implement stage III of the Graded Action Response Plan. The measures will be implemented from 8 am tomorrow.

What is GRAP III

• It is the third phase of anti-pollution measures that are implemented when AQI reaches 'Severe' (401 to 450).
