About 20 million people in France are bracing for the start of night curfews from midnight Friday (22:00GMT).
The entire Paris region will have night curfews – from 21:00 to 06:00 - for at least a month, as will eight other cities, including Marseille, Lyon, Lille and Toulouse.
So what are the dos and don’ts?
Restaurants, bars, cafes and cinemas must shut at 21:00 and diners remain restricted to six maximum per table, French media report. Food outlets can still provide night-time deliveries.
Jogging and dog-walking will still be allowed during the curfew but, as during the two-month lockdown, a signed permit will be required, which can be downloaded onto a phone.
France is deploying 12,000 police officers specifically to enforce the curfew. The fine for a violation will be €135 (£122) and a repeat offender could face six months in prison and a €3,750 fine.
The few exemptions include medical emergencies, essential home care visits and travel by train or plane at night. Shift workers with late hours may also break the curfew.

All bars and cafes in Paris will close for two weeks to help battle coronavirus
European countries are racing to control increasing infection rates, with tighter measures being imposed in several cities.
- From Tuesday bars in Paris will have to shut for two weeks and the capital's restaurants and cafes must tighten their hygiene measures. Similar rules are already in force in Marseille. Paris universities can only have lecture halls half-full. The French government is alarmed that in Paris the infection rate is now above 250 per 100,000 people, and Covid patients account for more than 30% of intensive care beds.
- In Moscow schoolchildren will have to stay at home for two weeks and firms have been told to keep at least 30% of staff working from home. Russia's daily infection rate has risen to 10,888 - the highest since May.
- The Czech Republic has reimposed a state of emergency, as its two-week average infection rate is 303 per 100,000, with only Spain's (319) higher in Europe, according to EU experts. Czech borders remain open, but indoor gatherings are limited to 10 people maximum.
- Ireland's emergency health team, the NPHET, has recommended measures almost as tight as a full lockdown. Level Five would see all indoor gatherings banned and bars and restaurants only able to do takeaways.
