On the Autoroute Blanche (A40) and the Route Blanche (RN205), as well as throughout the French road network, the number and location of speed radars are set by the prefecture, meaning by the government.
The income generated from the offenses that they sanction are collected by the government.
They are positioned according to the locations configuration.
Thus, the fixed radar most recently installed on the Autoroute Blanche (A40), after the Vuache tunnel going Geneva-Lyon, aims to reduce the speed of vehicles in this dangerous area that combines tunnel exits, descents and curves.
