Does the national gendarmerie or the national police intervene on all types of traffic accidents or only those that have had casualties?
The gendarmerie is likely to intervene on all accidents if need (particular risks, important disturbance of the circulation ...)
On the other hand, the police does not always write a report on an accident, depending on the particular conditions (injured or people taken to the hospital, deaths, damage to the public domain, …).
