In an attempt to tackle dangerous levels of air pollution, alternative driving days are being introduced into the French capital, Paris.
Starting Monday, drivers will only be able to use their vehicles every other day.
This is the second time since 1997 that such a restriction has been enforced in the French capital, reports BBC Online.
The French government made the decision after air pollution exceeded safe levels for five consecutive days in Paris and its surrounding areas.
The ban will also cover motorcycles, which will allow only vehicles with number plates terminating in an uneven digit to take to the roads, beginning at 05:30 (04:30 GMT) on Monday.
In an attempt to encourage people to leave their cars at home, public transport was made free of charge for three days on Friday; this measure will continue on Monday.
The air quality of Paris has been one of the worst on record, French environmental agencies say, rivalling the Chinese capital, Beijing, one of the world's most polluted cities.
The smoggy conditions have been caused due to a combination of cold nights and warm days, which have prevented pollution from dispersing.
On Friday, pollution levels hit 180 microgrammes of PM10 particulates per cubic metre; more than double the safe limit of 80.
PM10 particulates are emitted by vehicles, heating systems and heavy industry.
The government will review pollution levels on Monday, before deciding whether to extend the driving restrictions for longer.
