FREQUENTLY ASKED QUESTIONS
The Annual Technical Inspection (ATI) is a mandatory check of the roadworthiness of all motor vehicles operating on the national road network. Its purpose is to ensure road safety and environmental protection.
Yes, this is the most important change. As of May 7, 2026, the inspection stations' information system is connected to the Ministry of Interior and will block the inspection if the owner or driver has unpaid fines (tickets or penalty notices).
New passenger cars undergo their first ATI in the third year after registration, the second in the fifth year, and every year thereafter.
Taxi vehicles, ambulances, buses, and cargo vehicles over 10 years old must undergo inspection every six months.
You need to prepare the following documents:
- Original small vehicle registration certificate
- Personal ID card
- Proof of paid vehicle tax
- Valid Third-Party Liability insurance policy
No. The system automatically verifies the payment of the local vehicle tax with the respective municipality. Without paid tax, a valid inspection certificate cannot be issued.
During the inspection, the vehicle receives an eco-category (from 1 to 5) based on its actual emissions and Euro standard. This determines your access to central city areas on days with high air pollution.
If 'major defects' are identified, you have a 30-day period to fix them. After the repairs, you must return to the same inspection station for a re-check.
Yes, the gas system is checked for leaks and must have a valid certificate (passport). The vehicle must also have a 'GAS' sticker on the rear window.
The fine starts from BGN 50, but the greater risk is that the vehicle may be taken out of circulation, and the insurer may refuse to pay compensation in case of an accident.
As of 2026, paper stickers have been replaced with digital certificates. Validity is checked by registration number through Traffic Police cameras.
Yes, the Bulgarian ATI certificate is recognized in EU member states, but only while the vehicle remains registered in Bulgaria.
As of May 7, 2026, the system will automatically block the start of the ATI if the owner or the person presenting the vehicle has outstanding liabilities (penalty decrees or electronic tickets). This is in accordance with Art. 147, para. 9a of the Road Traffic Act.
You can make a quick ATI check on the Boleron website by entering your registration number.
We automatically track your deadlines and send you a notification by email or through the app weeks before expiration, giving you time to pay any fines and schedule your inspection.
