Météo France, the country’s national weather service, added two more counties to a list of over 20 in the Breton, Loire, Centre and Ile de France regions on high alert for the cold weather.
Members of the public are urged to be “very vigilant”, especially when driving, as temperatures are set to dip as low as minus five degrees and snow and black ice set in.
The cold weather has caused traffic problems throughout the northern regions, with both the transport and the interior minister urging the population to stay safe.
They urged the public to be "extremely vigilant while travelling and going about their daily lives because of the high risk of falls and accidents.”
They also recommended not travelling at all if possible.
The Maine-et-Loire county has already reported 10 accidents due to icy conditions, injuring seven people, since 2am.
School transport in four of the regions placed on orange alert has also been cancelled.
The orange alert is expected to hold until 3pm local time, and temperatures are expected to rise by a few degrees later in the week.
