The most common reasons for rejection during a technical exam

As we saw previously, the technical examination is a mandatory process that covers everything from visual aspects to the operation of mechanical and safety systems to emissions of polluting gases. This procedure aims to check that your car is in good condition, complies with the highway code in force and ensures road safety. In addition to being a crucial step in controlling the pollution produced by the vehicle fleet.

However, this procedure raises doubts among drivers who face a refusal, whether for a minor problem, such as the height of the lights, or a serious defect, such as brake problems.

Lights in poor condition: The lighting system must meet certain requirements. The first and most obvious is that the front, rear, turn signal and license plate lights must light up correctly, in addition to respecting the established colors, but they must also have their lenses in good condition. Additionally, headlights should be aimed so as not to dazzle oncoming drivers. This is one of the most common reasons for rejection and it mainly happens because when changing bulbs, many drivers do not realize that the light has remained in the position recommended by the manufacturer.

Damaged glass and windshield: Cracked or broken glass or windshield compromises the driver’s visibility and can lead to a refusal. In addition, following the shade rule also causes headaches.

Patent visualization issues: Although they were common and completely harmless a few years ago, patent frames have been banned from our road regulations. Although the majority of drivers who owned these elements did so to have a distinctive element with the name of their city or country, the truth is that over time some license holders appeared who could avoid paying for the label, so the decision was made to ban them completely.

Brake system failures: Brake system problems are a recurring cause of refusals. Worn or poorly adjusted brakes compromise vehicle safety, distributing braking force poorly and contributing to loss of control in an emergency.

Polluting gas emissions: High levels of pollutant gas emissions can lead to discharge. This problem affects both air quality and vehicle performance and is usually due to causes such as poor management of the injection of the air-fuel mixture, poor reading of the sensors that manage the system. exhaust or leaks in the exhaust pipe.

Suspension issues: A faulty suspension system can affect the stability and handling of the vehicle, constituting grounds for refusal. Shock absorbers leaking fluid and excessive bounce are the primary cause for rejection of this item.

Worn tires: Lack of tread depth or tires with cuts and deformations may result in rejection of the technical inspection. The lack of rotation during maintenance periods also contributes to making this cause of rejection common, since the greatest wear occurs on a single axis, rather than uniformly.

Other visual and mechanical aspects: Doors that are difficult to open or close, inconsistencies in chassis and engine numbers, faulty seat belts or even poor alignment with a bent steering wheel are also common reasons for refusal.

• Analyze and resolve the cause: In the event of refusal, a certificate detailing the reasons will be provided to you. Identifying the problem is the first step.
• Repair in a technical service: Go to a technical service with specialized professionals to repair and adjust the items indicated in the rejection certificate.
• Show the vehicle: After the repair, you have 15 calendar days to resubmit the vehicle for technical inspection, without having to pay the full price if this is carried out in the same factory.
