Before a new wave of COVID-19 cases swept the new city, a 430-mile traffic jam blocked Paris for hours.
The second nationwide lockdown took effect at midnight, and until June 1, only 65 million people left their homes for food shopping, medical care and work.
As the country battles another surge in coronavirus infections-the highest level since April-only schools and basic businesses will remain open.
BBC News quoted French media as saying that the recent blockade seemed to have caused Parisians to flee the city.
But Thursday also marks one of the last days people can go home after the school semester in the country ends, which ends on “All Saints̵
“At present, it is impossible to determine whether the traffic jam is due to blockade or [people returning from] Holidays,” a spokesperson for the Paris Regional Transport Authority told CNN.
Traffic jams in the Île-de-France region are 430 miles long. Social media videos show that cars are barely moving and drivers honk their horns in frustration.
According to the BBC, France recorded 47,637 new COVID-19 cases and 250 new deaths on Thursday.
