As soon as the declaration file is received, the competent administrative authority refers the matter to the local traffic police authorities for their opinion. If the prefect is the competent administrative authority, he may also refer the matter to the departmental road safety committee for its opinion.
This administrative authority may prescribe additional measures to those planned by the organiser if the latter appear insufficient to guarantee the safety of road users, participants and spectators, to ensure satisfactory traffic conditions and to protect public safety.
