The Foreign and Commonwealth Office (FCO) has updated its travel advice to France, ahead of two planned strike days across the country.
The first, which takes place on Wednesday, November 27, involves planned protests by farmers.
The FCO said: "In the Paris region, protests will begin early in the morning and are expected to include road blockades on motorways and main roads into the city. Similar protests can be expected elsewhere in France. You should plan your travel accordingly."
Starting on Thursday, December 5, a nationwide transport strike is planned and Air France workers are expected to take part.
The FCO said the strike ‘will primarily affect public transport with cancellations and severe delays expected on trains, metros, buses and trams’.
It added: "Demonstrations by hauliers on some major roads may also cause delays or blockages. Strike action by Air France workers may also cause disruption to air travel. You should check services before travelling.
"Additional protests may also be held linked to the yellow vest (gilets jaunes) movement. In all cases, you should avoid demonstrations wherever possible and follow the advice of the local authorities.
"If demonstrations do turn violent, a heavy police/gendarmerie presence is to be expected.
"Motorists travelling through France may continue to experience some delays or blockages caused by local demonstrators – you should drive with caution as protestors may be present on roads, motorways and toll booths. In all cases, you should avoid demonstrations wherever possible and follow the advice of the local authorities.
"If you’re crossing the Channel, check the website of your chosen operator before you set off.
"In the event of any disruption, information about alternative routes and operators is available via this interactive map."
The FCO repeated its advice that protests linked to the yellow vest movement continue across France, generally taking place on Saturdays.
