Certified indicators

The main statistical series produced by ONISR have been certified by the Public Statistics Authority since 2013. The latest ASP notice, dated 13 November 2025, renews the certification of the series concerning fatalities and recognises as ‘public statistics of general interest’ the series corresponding to the estimates of injuries produced by ONISR according to a methodology established in collaboration with Gustave Eiffel University.

The French Public Statistics Authority ensures that the design, production and dissemination of productions resulting from the use, for general information purposes, of data collected by administrations, are carried out in compliance with the principles of professional independence, objectivity, impartiality, relevance and data quality.

The certification of key indicators is essential for ONISR, because it recognises the essential work of an entire network of stakeholders (police forces, regional or departmental observatories, road managers, Cerema), who ensure the most objective possible vision of the situation and to challenge drivers' personal feelings.

Thus, in 2013, ONISR requested the certification of the main accident indicators by the French Public Statistics Authority (ASP). The Certification Committee, which now examines applications in support of the Authority, did not exist at that time. The first ASP notice was published in the Official Journal on 18 June 2013.

Certified statistics: 5 series certified by the ASP

Five sets of data produced by the French Safety Observatory and taken from the database of road traffic injury accidents recorded by police forces (BAAC) have been certified by the ASP (notice of 13 November 2025 under no. NOR ECOO2531862V).

These are the series of annual national figures for the number of people killed in road accidents (up to 30 days after the accident) in mainland France and the overseas departments and regions, broken down according to the following criteria (not cross-referenced):

by age group and gender (cross-referenced);
by mode of transport at the time of the accident (walking, cycling, e-scooter, passenger vehicle, etc.);
by road environment (motorway, roads outside built-up areas excluding motorways, roads within built-up areas excluding motorways);
by county (and therefore region) depending on the location of the accident;
by month of the accident.

Public statistics of general interest: 3 series recognised by the ASP

Three sets of data produced by the French Road Safety Observatory, compiled from the database of road traffic injury accidents recorded by police forces (BAAC) and modelling by Gustave Eiffel University based on a comparison with the Rhône road accident victim register (victims arriving at hospital emergency departments) have been certified by the ASP (opinion of 13 November 2025 under no. NOR ECOO2531861V).

These are the series of estimated annual numbers of people injured in road traffic accidents, including a series of serious injuries according to the MAIS3+ scale (1), aggregated series of injuries and serious injuries, and series disaggregated according to one of the criteria below:

by age group and gender (cross-referenced);
by mode of transport at the time of the accident (walking, cycling, personal motorised transport, passenger vehicle, etc.);
by road environment (motorway, non-motorway roads outside built-up areas, non-motorway roads within built-up areas).

(1) An injury is considered serious if its maximum injury score (Maximum AIS or MAIS) is equal to or greater than 3 (MAIS3+), with each non-fatal injury to victims being coded on this scale ranging from 1 to 5, with 1 corresponding to the least serious injuries.
