Failed Your Vehicle Inspection: Minor/Major Defects and What to Do

By Edip Ertürk · 2026-07-20 · Updated 2026-07-21

Coming out of a vehicle inspection with a "major defect" or "unsafe" report is common, but most vehicle owners don't fully know what to do next. The TÜVTÜRK (Turkey's official vehicle-inspection operator) report doesn't just state whether you passed or failed — it also records which defect class applies, and that class determines how quickly, and at what cost, you must bring your vehicle back for re-inspection. You can check our Vehicle Inspection guide for the process overall; this article focuses directly on the "I failed — now what?" question.

Defect classes: minor, major, and unsafe

As a result of the periodic inspection, TÜVTÜRK evaluates the vehicle with one of four outcomes: defect-free, minor defect, major defect, or unsafe. TÜVTÜRK

• Minor defect: small shortcomings that don't directly threaten traffic safety but don't fully meet the standard, such as an unreadable engine number, a small scratch on the glass, missing washer fluid, or an oil leak at seepage level. The vehicle passes the inspection in this case; the shortcoming is expected to be fixed by the next inspection.
• Major defect: defects that directly endanger traffic safety or cause serious harm to the environment; the vehicle fails the inspection. The main systems checked during inspection include the steering system, the braking apparatus, the chassis, and chassis connection parts; serious faults in these systems fall under the major-defect category. Directorate General for Transportation Services Regulation A license plate missing from the vehicle also counts as a major defect. Directorate General for Transportation Services Regulation If you don't have a valid exhaust-gas emission measurement, your vehicle is also considered to have a major defect: "If you don't have a valid exhaust emission measurement, your vehicle is evaluated as 'Major Defect' at inspection." TÜVTÜRK
• Unsafe: the most severe outcome, given when the vehicle's condition poses a direct danger to the life and safety of the driver, passengers, or other traffic participants if driven as-is; the report is not approved. TÜVTÜRK

In both the major-defect and unsafe outcomes, the vehicle fails the inspection; the real difference lies in the severity of the defect and in the penalty applied if the vehicle is driven without being fixed (covered in the last section of this article).

Re-inspection deadline and fee (TÜVTÜRK tariff)

After fixing the defect, the owner of a vehicle that came out major-defect or unsafe can use their one-time, free re-inspection right within one month, at any station nationwide that serves the same vehicle group. TÜVTÜRK The period runs from the date of the first (paid) inspection; if you return for re-inspection after the one-month period has passed, you lose the free re-inspection right and must have a new, paid general inspection done. TÜVTÜRK

Under the 2026 tariff, the passenger-car inspection fee is 3,288 TL; the exhaust-gas emission measurement is 460 TL and can also be done without an appointment before the inspection. TÜVTÜRK The free re-inspection falls outside this tariff — as long as the conditions above are met, you make no additional payment.

Most common reasons for failing inspection

In practice, most vehicles fail on the same handful of items:

• Braking system: worn brake pads, cracked discs, a handbrake that doesn't hold, leaks in hydraulic lines.
• Lighting: headlights, taillights, or turn signals that don't work or are misaligned.
• Tires: tread depth below the legal limit, tires with sidewall deformation.
• Exhaust-gas emissions: a missing or expired emission measurement, which must be obtained separately before the inspection.
• Windshield cracks that block the driver's field of view and an unreadable license plate — both are direct causes of a major defect. Directorate General for Transportation Services Regulation

Most of these shortcomings can be prevented with a simple check a few days before going to inspection. For appointment and process steps, see our How to Book a Vehicle Inspection Appointment article, and for not missing your inspection date, see our When Is Vehicle Inspection Due article. If you're missing documents you need to bring to the inspection, the process won't even start; the current document list is in Documents Required for Vehicle Inspection.

The process after fixing the defect

1. Have the defect (or defects) noted in the report fixed at an authorized service center or a suitable mechanic; keep the invoice if a part was replaced.
2. Go to the same or a different TÜVTÜRK station before the one month is up — the free re-inspection right is valid at any station serving the same vehicle group, regardless of which station you originally used. TÜVTÜRK
3. Bring the report you received at the first inspection; the station's system will already see, via your license plate, that you're eligible for the free re-inspection.
4. If the defect has been fixed at the re-inspection, the vehicle receives a passing grade; if it hasn't been fixed, or if you don't return within one month, the process starts over and the full fee is charged again. TÜVTÜRK

The risk and penalty of driving with a major-defect or unsafe vehicle

The one-month correction period doesn't mean "you can drive the vehicle around however you like during this time." TÜVTÜRK's own FAQ source states this explicitly: it's recommended that a vehicle found to have a major defect not be used in traffic until the shortcomings are fixed. TÜVTÜRK

Law No. 2918 on Highway Traffic (Karayolları Trafik Kanunu) regulates the matter in separate clauses; according to the General Directorate of Security (Emniyet Genel Müdürlüğü)'s 2026 traffic administrative fine guide, the applied amounts are as follows: General Directorate of Security

• Article 34/a — driving a vehicle that hasn't had its inspection done: 2,719 TL (2,039.25 TL with the 25 percent early-payment discount). The vehicle is barred from traffic; the driver is given up to seven business days of additional time to get the inspection done.
• Article 34/b — driving the vehicle in traffic still without an inspection after the additional time granted following the traffic ban has run out: 5,662 TL (4,246.50 TL discounted). The vehicle is barred from traffic again.
• Article 34/c — driving in traffic a vehicle given an unsafe report at inspection: 5,662 TL (4,246.50 TL discounted). In this case too, the vehicle is barred from traffic and likewise sent for inspection with an additional time period.

In summary: if the report comes out "major defect" or "unsafe," driving the vehicle without fixing it means both a monetary fine and the vehicle being barred from traffic with an obligation to bring it in for inspection within seven business days. The safest and cheapest path is to fix the defect as soon as possible and use your free re-inspection right before the one month is up.
