This weekend is one of the busiest of the year with holidaymakers going and returning and many other day trippers taking to the roads and motorways.
Bison FutÃ©, the French government run site that monitors traffic levels, has placed the north west of the country on orange alert for Friday and red alert for Saturday.
It is predicting intense traffic in both directions on major routes and also warning that coastal roads could also be busy.
â€˜If you are taking main roads and also travelling through cities we recommend that you travel between 3pm and 7pm to avoid the busiest times on Friday,â€™ a spokesman said. For Saturday the busiest times on the roads are likely to be between 10am and 6pm. Traffic jams are not expected on Sunday.
Weather forecasters say that the weekend is going to be hot in sunny throughout Normandy but temperatures will be fresh due to light winds, especially on the coast.
Temperatures are likely to reach 22 degrees on Saturday and 25 degrees on Sunday although the day may start overcast but the cloud is expected to clear.
People using motorways in Normandy are paying more. Prices in the region increased the most in 2012, according to Franceâ€™s public audit office. Tolls increased by 3.03% in 2012 and the SociÃ©tÃ© des Autoroutes de Paris Normandie (SAPN) increased them again by an average of 2.29% in February, the biggest rise in France.
It means that the cost of driving from Rouen to Caen increased from â‚¬8,60 to â‚¬8,90, a rise of 3.49%. From Paris to Rouen it has risen from â‚¬6,10 to â‚¬6,20, an increase of 1.64% and from Paris to Caen it has gone up from â‚¬14,70 to â‚¬15,10, a rise of 2.72%.
The audit office has criticised the motorway operators for not being transparent enough about how the toll money is spent and how they decide on the prices. It also believes that tolls should not rise above inflation.
Franceâ€™s motorways were privatised in 2006 and sections are now operated by different companies who choose their tariffs. Concerns have been voiced that it is the users of the motorways that are having to pay the most towards the maintenance and upgrading of the roads rather than the companies using other financial options.
