Preparing your vehicle for an STK (Technical Inspection Station) is crucial to ensure it successfully passes the technical inspection. Here are a few steps to help increase your chances of a smooth STK process:
1. Check the Lighting
Lighting issues are one of the most common reasons vehicles fail STK. Check all lights, including front, rear, brake, turn signals, and license plate lights. Make sure they are all functioning correctly and are not damaged.

2. Condition of Tires
Tires must be in good condition, with a sufficient tread depth (at least 1.6 mm for passenger cars) and free of visible damage. Check the tire pressure and inflate them as needed.
3. Brakes and Braking System
Brakes are a critical safety feature of your vehicle. Check that the brake pads and discs are not worn. If the brake pedal feels soft or brake fluid levels are low, it may be necessary to top up or replace the brake fluid.
4. Engine Oil and Fluids
Check and, if necessary, top up all vehicle fluids, including engine oil, coolant, brake fluid, and windshield washer fluid. Ensure there are no leaks.
5. Bodywork and Mirrors
Inspect the vehicle’s body for any corrosion or damage that might compromise safety. Make sure all mirrors are intact and properly adjusted.
6. Emissions Inspection
The emissions inspection is often part of the STK. Ensure the exhaust system is in good condition and that the vehicle does not emit excessive smoke or exhaust gases. If in doubt, visit a service center where emissions can be checked and adjusted.
7. Visual Inspection of the Interior
The vehicle’s interior should be clean and free of loose objects that could pose safety risks. Check that all seat belts function properly and that all seats are securely fixed.
8. Documents
Prepare all necessary documents you’ll need for the STK:
- Vehicle registration certificate,
- Personal identification document,
- Proof of vehicle insurance,
- Emissions inspection certificate (if separate from the technical inspection).
9. Preliminary Service Check
If you are unsure about your vehicle’s condition, it’s a good idea to have it checked at an authorized service center. Mechanics can identify issues you might overlook that could lead to a failed STK inspection.
10. Important Details
Don’t forget small but crucial elements:
- Functional horn,
- Wipers and windshield washers,
- Check the functionality of safety features such as airbags.
Preparing your vehicle for STK can make the difference between passing or failing the inspection. By following these steps, you ensure your vehicle is in optimal condition and ready for the technical inspection. This way, you save time and money on repeat inspections and, most importantly, enhance your vehicle’s safety on the road.
