Opening a vehicle-inspection centre in France: prefectoral approval step by step

A vehicle-inspection centre project looks like a garage project: premises, an inspection lane, heavy equipment, a financing plan. It differs on one point that changes everything: the activity is approved by the prefect (préfet, the State’s representative in each département), and that approval is not something you request at the last minute. Here is the real sequence.

Three approvals, not one

The French highway code devotes articles R. 323-6 to R. 323-21 to the approval of inspectors, facilities and networks. Three distinct objects:

• the facility, that is the centre itself: one site, one vehicle category, a set of equipment;
• the inspector (contrôleur), a natural person whose approval is individual and requires employment by an approved operator;
• the network, a national structure federating centres under a shared organisation, approved by the transport minister.

An approved centre without an approved inspector inspects nothing. Both files therefore advance in parallel — we cover the second in our article on becoming a vehicle inspector.

Step 1: choose your scope

Each vehicle family has its own ministerial order (arrêté), and therefore its own approval:

Scope	Governing text
Vehicles up to 3.5 tonnes (light vehicles)	Order of 18 June 1991
Heavy vehicles	Order of 27 July 2004
Two- and three-wheelers and motor quadricycles (category L)	Order of 23 October 2023

A light-vehicle approval does not allow you to inspect motorcycles: the category L scope, mandatory since 15 April 2024, requires a facility approved for that category and inspectors qualified accordingly. We devote a separate article to it: what category L changes for centres.

This choice is not only technical. It drives equipment costs, floor space and the customer volume you can reach in your catchment area.

Step 2: approved network or independent centre

This is the second structuring decision, and it has an immediate effect on how your file is processed.

Attached to an approved network, your application includes the network’s opinion and the documents listed in chapter II of annex VII to the order of 18 June 1991. In exchange, you adopt the network’s methods, tools and brand.

Independent, your application includes the opinion of the central technical body and the documents in chapter III of the same annex. You keep commercial freedom and carry the regulatory watch and quality organisation alone.

In practice, the file is submitted in two copies, raised to three for a centre not attached to a network.

Step 3: secure the site and the equipment

Nothing is usefully filed until the site is under control. The facility must allow every inspection point of the applicable method to be carried out: a properly dimensioned inspection lane, a lift or pit, a brake tester, emissions measurement devices, a headlamp aligner, and public reception areas complying with the rules for premises open to the public.

Two habits to build at this stage:

1. Document calibration and maintenance of measuring equipment. These devices produce enforceable results; their periodic verification is part of what monitoring looks at.
2. Write the schedule backwards from your target opening date: works, equipment delivery, filing, processing time.

Step 4: the independence undertaking

This is where poorly designed projects collapse. The approved centre undertakes to carry out no vehicle repair or sales activity and not to use inspection results for purposes other than those set by the regulations.

In other words: you cannot bolt an inspection lane onto an existing workshop and count on customers flowing from one to the other. If your business model relies on that traffic, it must be redesigned before anything is filed. We set out the exact reach of the rule in inspection and repair: the separation that underpins the trade.

Step 5: file and wait

The application goes to the prefecture of the département where the centre is located. The file covers the operator’s identity and good repute, control of the site, equipment conformity, the quality organisation, a named list of inspectors and their qualifications, plus the opinion of the network or of the central technical body.

One rule protects the applicant: silence kept for four months counts as an acceptance decision. You still need to date the start of that period — hence the importance of the acknowledgement of receipt.

What this approval buys you

The strictness of the framework follows from its purpose: producing consistent, credible inspections nationwide. The usefulness of periodic inspection itself remains debated in the academic literature — Alex Hoagland and Trevor Woolley, in “It’s No Accident: Evaluating the Effectiveness of Vehicle Safety Inspections”, published in 2018 in Contemporary Economic Policy (see the study), found no significant rise in crashes attributable to mechanical failure after New Jersey ended mandatory inspections in 2010. That result does not say inspection is useless: it is a reminder that its value depends closely on the quality and consistency of its execution. Which is precisely what approval, the technical instructions and UTAC-OTC oversight organise.

For an operator, that translates into continuing duties: apply the technical instructions in force, keep qualifications current, cooperate with monitoring visits. The prefect may suspend or withdraw the approval when conditions are no longer met.

Where does training fit in?

A centre only lives if it finds inspectors. The occupation has a registered certification — the professional title of light-vehicle inspector, entered in the national register of professional certifications (RNCP) under number 37320 — and the providers preparing candidates for it must meet the requirements of annex IV to the order of 18 June 1991. Those seeking public or pooled funding for such programmes must also hold Qualiopi certification: see our article on training vehicle inspectors and our overview of French certifications and approvals.

Take action

Scope, affiliation, site, independence, application: approval of a vehicle-inspection centre is prepared in that order, and each step conditions the next.
