The new signs will be placed between 1 to 2km before the cameras, and are designed to stop people slowly down upon seeing the cameras and then speeding up afterwards.
The first sites for the cameras are:
- Lamonzie St. Martin in the Dordogne (24) R & D 936 in the direction Bergerac to Bordeaux, from August 3
- Sausheim in the Haut-Rhin (68) on the A36 in both directions, August 4
- Rouffach dans le Haut-Rhin (68) sur la RD 83 dans les 2 sens le 4 août. Rouffach in the Haut-Rhin (68) on the RD 83 in both directions, August 4
The French government claims average speeds have dropped since the introduction of cameras, reducing the number of deaths on the roads.
France has 1,689 speed cameras, including 234 devices at traffic lights and law enforcement officers are equipped with 933 mobile cameras.
