Vehicle inspection: which defects cause the most failures in France?
The vehicle inspection (contrôle technique) is a mandatory step for all motorists in France. However, many vehicles do not pass this inspection on their first attempt. According to the latest data, certain technical defects appear very regularly and prevent the certificate from being validated.
Among the most frequent causes of failure, problems related to lighting and signaling come out on top. Burnt-out bulbs or poorly adjusted lights are minor faults, but they require the owner to undergo a re-inspection. It is therefore advisable to check the condition of your headlights before heading to the inspection center.
Braking systems and tires also constitute major points of concern. Excessive wear on brake discs or pads, as well as tires with insufficient tread depth, are considered major faults. These elements are essential for road safety and must not be neglected by drivers.
Finally, pollution problems are among the most common reasons for refusal, particularly for older diesel vehicles. A poorly maintained engine can emit fumes that exceed authorized standards. Regular maintenance of the engine and exhaust system often helps to avoid this type of inconvenience.
To pass your vehicle inspection, prevention remains the best solution. Annual maintenance by a professional makes it possible to identify these defects before the official examination. By taking care of their vehicle, French motorists can not only avoid a costly re-inspection, but above all ensure their safety and that of other road users.
