The speed camera most likely to flash at motorists is on the A41 motorway between the south-eastern town of Annecy and the Swiss city of Geneva.
The exact point is close to Saint-Julien-en Genevois, which is next to the Swiss border. The speed camera there reportedly flashes 462 times a day on average.
The second most active camera is in the Paris suburbs, between the south-west Puteaux and Issy-les-Moulineaux on the RD1 (route départementale), which follows the path of the river Seine.
The third busiest camera is on the A7 motorway between the southern cities of Lyon and Marseille.
The magazine also finds the most idle speed camera in the country, which sits between Saint-Aulaire and Varetz in the central Limousin region.
The magazine also warns its readers about cameras situated close to traffic lights, which are far more likely to catch offenders than others.
Of those, nine of the ten most active are in Paris, with the busiest in the centre of the city at the junction of Quai de Gesvres and the rue Saint Martin.
