France has shared an update as more people could be travelling to the country in the coming weeks ahead of D-Day commemorative events. This could cause disruptions to travel.
The new warning comes amid an ongoing guidance about various security risks in the country.
The Foreign, Commonwealth and Development Office (FCDO) has updated its safety and security advice for Britons heading to Normandy.
It said: "Between 5 and 7 June commemorative events for the 80th anniversary of the D-Day landings will take place in Normandy. Commemoration events are ticketed and it’s not possible to attend if you’re not in possession of a ticket in advance.
There is an ongoing threat of terrorism across France
PA"On 6 June from 6am until 8pm, there will be a restricted traffic zone north and west of Caen from the RN13 road area to the sea. You must display a vehicle sticker on your windshield in this area.
"Check the Calvados Prefecture D-Day 80 page (in French) for further information, including a map of the restricted areas. Some roads may be closed, allow extra time for your journey."
Holidaymakers should be aware of potential disruptions over these dates and allow extra time for moving around the region.
The FCDO has an ongoing alert regarding terrorism in France as it states "terrorists are very likely to try to carry out attacks" in the country.
Busy, touristy spots are most likely to be targeted and holidaymakers should follow the advice of authorities in the case of an emergency.
The Government body warned: "Terrorism attacks could be indiscriminate, including in places frequented by foreign nationals such as shopping centres, entertainment establishments, cultural events, public transport and places of worship.
"Methods of attack have included knife attacks, shootings, bombings and vehicle attacks. Be vigilant in public places and follow the advice of local French authorities."
Britons in France have been warned of "unexpected" tourist tax hikes that have taken place this year.

Britons should be aware of this when visiting
PANew hikes could add £350 to the cost of a holiday for a family of four as the fees have increased by around 200 per cent in some cases.
How much tourists need to pay depends on the type of accommodation they stay in and it is usually payable at the hotel.
The highest taxes apply to guests who stay in a palace and they are charged €14.95 (£12.75) per person per night.
