The roads are expected to be extra busy as many people will be taking a holiday from work on Friday 10 May, known as a pont, connecting the bank holidays of Wednesday and Thursday with the weekend.
Police officers in Calvados hope that people will remain as prudent as they have been recently. Figures show that April saw a fall in the number of deaths on the roads, with just three people killed.
â€˜But we are urging people to be careful this weekend, especially on Sunday when many will be returning for visits to family and from short breaks. Traffic controls will be operating across the department,â€™ said a Calvados prefecture spokesman.
â€˜For many Sunday will be the end of a very long weekend of five days. We want people to enjoy their time off and to take care,â€™ he added.
A vigilance red has been declared for roads across much of France which means traffic is expected to be very heavy and traffic flow difficult. In Normandy there could be traffic jams around popular tourist spots such as Mont Saint Michel and the D-Day landing beaches which are already becoming popular with visitors, many of them foreign, ahead of the annual D-Day commemorations next month.
Roads around the ports of Cherbourg, Ouistreham, Le Havre and Saint Malo are also expected to be busy as people return from trips to the UK.
Driving organisations are urging people who have been away to try to return on Sunday morning when the roads are likely to be less congested than later in the day. The worst traffic jams are likely to be between 3pm and 9pm, according to the Association PrÃ©vention RoutiÃ¨re (APR).
â€˜A driver on good form, a car in good working order and a route well prepared are the keys for a safe journey this weekend,â€™ said an APR spokesman.
It is advising drivers to check their cars before starting out, including wind screen wipers and brake lights, to prepare their route and to respect speeds and road controls. Some rain and wind is expected during the weekend.
â€˜Driving on a motorway is more tiring for those who do not do it all the time, especially on longer journeys. Often concentration can be affected by the monotony of the route. Losing concentration is one of the main causes of fatal accidents on motorways,â€™ the spokesman explained.
