RAC fuel spokesman Simon Williams said: “The fuel shortage situation in France caused by industrial action is unfortunately worsening. Initially the problems were focussed on northern France from Brittany to Calais, but we are now getting reports from the central, western and southern regions of the country too.
“Anyone currently in France is going to struggle to find fuel for their return journey and probably shouldn’t even attempt to get home unless they can do so on one tank. We suspect finding somewhere to fill up in the worst affected areas will be extremely difficult.
“If you are just about to go to France, you should fill up in the UK before your crossing to give you the best chance of reaching your destination in one go. If you are travelling a very long distance you will obviously need to refuel which could mean a long wait at a service station due to rationing in some areas. Motorists should also be very mindful of not running out of fuel and finding themselves stranded.
“At the end of last week we helped a number of RAC members in France find fuel but this is no longer possible. We will continue to monitor the situation on behalf of our members in Europe.”
