Almost a third of vehicles that are 10 years old or more fail their contrôle technique (CT) the first time in France, and Renault, Peugeot, and Citroën are among the brands most likely to

fail.

Figures from the latest annual contrôle technique authority UTAC-OTC (Organisme Technique Central) report show that the older a car is, the more likely it is to fail the technical inspection

the first time, requiring repair work to be carried out before a re-test.

Unsurprisingly, vehicles that have not received regular maintenance or have been heavily used are the most likely to fail. Vehicles under the age of five are the least likely to fail their

first CT.

Cars in France are, on average, 12.9 years old (show figures as of 2024). Also in 2024 more than 19 million vehicles undertook a CT.

In 2024, the models most likely to fail (all models and ages combined) first time were: 

For cars between 10 and 14 years old, failure rates are even higher. 

And while failure is most likely a problem for vehicles over a decade old, more recent models can also be affected. 

Some of the main reasons for these failures are tyre wear, worn-out suspension, and headlight problems. High levels of pollutant emissions are also increasingly the cause of first-time

failure.

Older vehicles, particularly diesel vehicles from before 2011 (pre-Euro 5 standard), may find it increasingly difficult to meet the requirements of the inspection due to pollutant levels.

Some models have high rates of failure for specific issues. For example:

Peugeot 106: Emission problems and advanced corrosion of the chassis

Renault Espace III: Defects in the suspension and braking system

The figures show that French car models are most likely to fail their first CT, largely because there are more of them on French roads. In contrast, German models such as BMW, Audi and

Volkswagen perform better, on average, in their CTs. 

This is considered due to the initial robust design of these vehicles, and the fact their owners are generally more likely to maintain their vehicles to a higher level, states specialist

website Carte Grise.

A contrôle technique is a technical inspection that is compulsory for vehicles over four years old and must be carried out every two years in France.

The first inspection must be carried out during the six months preceding the fourth anniversary of the first registration of the vehicle. No reminder is sent; you must remember to book it

yourself.

A CT checks almost 150 elements on a vehicle, and is similar to an MOT in the UK. It is required to ensure safe driving and compliance with vehicle laws, including being in a good state of

repair, and complying with increasingly strict environmental standards. 

If your vehicle fails the CT it is considered to have major defects and, in severe cases, to be a danger to its driver and other road users. Defects must be fixed to ensure it meets the

standard, and then re-tested. Less serious issues will lead to you being “highly recommended” to fix them.
