GRAP 4 restrictions in Delhi-NCR? Here's what's allowed and what is not when pollution levels cross 451 mark

Delhi is enveloped in toxic smog, with the AQI at 341 in the very poor category. GRAP-III is in effect, but GRAP-IV, triggered by AQI above 451, has not yet been imposed. This stage would bring stricter measures like potential online classes, work-from-home mandates, and bans on certain vehicles and construction.
