During this time, Delhi frequently enforces restrictions under the Graded Response Action Plan (GRAP), which categorises air quality into four stages: Stage I (Poor) with AQI between 201 and 300, Stage II (Very Poor) between 301 and 400, Stage III (Severe) between 401 and 450, and Stage IV (Severe Plus) for AQI above 450.

According to the revised plan, inter-state buses from NCR states, except those EVs and those running CNG or BS-VI diesel, will not be allowed to enter Delhi under Stage II. This provision earlier came into effect under Stage III.
