This article deals with the minimum requirements for quality management at Periodical Technical Inspection Stations (PTIS) for road vehicles in the Slovak Republic, as well as in selected countries of the European Union. Specifically, it contains research performed at all of the PTIS in the Slovak Republic with a focus on the established quality management system and the number of employees of companies operating these PTIS, as well as similar research in selected countries of the European Union. Based on the research results, the article contains an assessment of the influence of the implemented quality management system on the operation of PTIS. The analysis of the results showed that 86.7% of PTIs have an established system to meet the minimum requirements for quality management through a documented procedure (internal regulation), and 13.3% of the PTI have the certified quality management system according to the STN EN ISO/IEC 9001 standard. Unfortunately, no PTI in the Slovak Republic has the fulfilment of quality management requirements according to the standard STN EN ISO/IEC 17020.

The paper analyses the assessment of the technical condition of vehicles at technical inspection stations in the Slovak Republic in the period of 2007 – 2019. There are described the legislative conditions for assessment of the technical condition of vehicles at technical inspections stations in the Slovak Republic. Data from technical inspections and defects within all technical inspection stations was recorded in the nationwide information system. These data was used as base for the next analysis. This paper also describes the possibilities for detection of deficiencies at technical inspection stations, and in the final part the impact of expert supervision on the operation of the selected technical inspection stations was analysed. The paper also examines significant factors affecting the assessment of the technical condition of vehicles at technical inspection stations in the Slovak Republic. The first factor represents legislative measures introducing more sophisticated technical means to control technical inspection stations, and the second factor is technical supervision by supervisory authorities over technical inspection stations.
