According to reports the price of diesel at some motorway service stations has risen by as much as 30 centimes.
France's National Road Committee (CNR) has reported an average rise of 6.6 percent in the cost of a litre of diesel between May13th and May24th.
Carbeo, an internet site that compares fuel prices in petrol stations, has reported the average cost of a litre of diesel having risen by 4.4 percent in the last week in France.
A spokesman for the France's competition and anti-fraud commission the DGCCRF could not confirm a hike in petrol prices, saying it was too early to tell.
But given that petrol prices in France could be set freely there was in any case nothing the government body could do to stop companies taking advantage of the crisis.
On the roads however, motorists were getting annoyed.
David, a moped rider, told Le Parisien newspaper how he had spent €18 filling his tank, when the normal cost is around €11.
“It's the most I've ever spent in my life to fill the tank,” he said.
