According to the circular of 27 June 2018 notifying the network of road safety observatories, the prefect implements the local (county-level) road safety policy defined at national level. To carry out these missions, it relies on local government services. To this end, a "road safety" competence centre is in place, including a local road safety observatory which ensures the relay at county level of the missions of the French Road Safety Observatory (ONISR).
At the regional level, under the authority of the Prefect of the Region, the Regional Directorate for the Environment, Planning and Housing (DREAL) is the level for ensuring the coherence and evaluation of local road safety policies and their integration into transport and investment policy on regional infrastructures. To carry out these tasks, the regional prefect has a regional road safety coordinator and a regional road safety observatory (ORSR) which provides him with accident reports and studies to be published periodically.
