Question 7876 — road safety

Summary

Mr. Maxime Michelet draws the attention of the Minister of Regional Planning and Decentralization to the proliferation of speed bumps on French roads and their non-compliance. As for roundabouts, France is the world champion in the number of speed bumps present on its territory with more than ten on average per municipality. According to data from several road user associations, a proportion significant number of speed bumps installed in France would not comply with the standards in force, in particular the NF P98-300 standard which governs the terms of their production. Some reports estimate that around 90% of speed bumps, or around 400,000, are non-standard. Many associations and road professionals denounce the damage caused to vehicles (suspensions, tires, chassis, etc.) due to these excessively high devices. high, poorly marked or poorly designed. The costs incurred by these automobile repairs can represent a significant burden, particularly for the poorest households. These non-compliant speed bumps are also a risk factor for motorcyclists. The inconsistent nature of the excess number of speed bumps with the country's ecological ambitions must also be underlined. According to a study carried out by motorist associations, Non-compliant speed bumps would cause up to 27% more consumption compared to the same road without a speed bump compared to 13% for compliant speed bumps. These crossings in fact require a sequence of braking then acceleration, increasing fuel consumption and emissions of CO2 and fine particles. This phenomenon is in opposition to the Government's speeches on the reduction of the carbon impact. Faced with these facts, it is important to remember that the non-compliance of speed bumps is often explained by the lack of resources and information available to the municipalities responsible for installing speed bumps. The Association of Mayors of France (AMF) regularly warns of the fact that the State only provides very limited financial support to communities for the maintenance of their roads. These must manage a considerable road heritage, with more than 700,000 kilometers of roads, which makes it particularly difficult, due to lack of resources, to bring existing speed bumps up to standard. He would therefore like to know if the Government intends to undertake a national census of non-compliant speed bumps and strengthen their legality control in order to enforce the imposed standards.
