On 24 March, Prime Minister Narendra Modi ordered a nationwide lockdown for 21 days beginning 25 March, limiting movement of the entire 1.3 billion population of India as a preventive measure against the COVID-19 outbreak. AP
On 25 March, the first day of the lockdown, nearly all services and factories were suspended. Police were instructed to make arrests across the country for violating norms of lockdown such as venturing out for no emergency, opening businesses, and home quarantine violations.
On 14 April, Narendra Modi extended the nationwide lockdown till 3 May, with conditional relaxation for the areas where the spread had been contained by 20 April. Lockdown areas were classified as 'red zone', indicating the presence of infection hotspots, 'orange zone' indicating some infection, and 'green zone' with no infections. AP
On 1 May, the MHA further extended the lockdown period to two weeks beyond 4 May, with some further relaxations. Movement was permitted in green zones with buses limited to 50% capacity. Orange zones would allow only private and hired vehicles but no public transportation. The red zones would remain under lockdown. AP
On 17 May, the National Disaster Management Authority (NDMA) and the MHA extended the lockdown for a period for two weeks beyond 18 May, with additional relaxations. Unlike the previous extensions, states were given a larger say in the demarcation of green, orange, and red zones and the implementation roadmap. Red zones were further divided into containment and buffer zones. AP
