Road transport safety, apart from environmental protection, is one of the most important tasks for the contemporary world. Annually, about 50 million people are injured in road accidents around the world, of which nearly 1.5 million die as a result. Transport safety consists of many activities and includes various initiatives, including legal changes, training, preventive actions, building safe road infrastructure, and the production of safe vehicles and control systems. This article deals with the issue of performing roadside technical inspections in the Slovak Republic. Specifically, it analyses the results of these oadside technical inspections in individual counties of the Slovak Republic and examines their possible impact on transport and logistics systems in these counties. The correlation analysis showed that the number of checks under the technical roadside inspections is weakly related to the number of logistics centres, but the number of such inspections is moderate in relation to the number of failed vehicles (correlation coefficient = 0.44079). In addition, due to the age of the vehicles, the number of serious and dangerous faults found on them during maintenance inspection increases.

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.

The safety of machinery is a very important aspect for its correct functioning in the conditions of modern production or assembly. According to the standards, manufacturers of special-purpose machines and devices are obliged to provide their equipment with a certificate of conformity (CE). This article describes the concerns of insufficient safety of a device. Insufficient coverage of part of the line meant that the certification did not take place, and the safety requirements were not met. The TRIZ method was used to resolve this technical discrepancy, providing designers with "instructions" on how to proceed, solve complex problems at the level of discrepancies and create solutions. By agreement of the designers, a solution that was not economically and implementation-intensive was created. All doors and windows within the fencing have been reinforced, thus achieving a greater degree of security. The resulting solution was subjected to simulations in the Ansys Workbench program, and the FEM analysis led to certain conclusions. The results were then moved to the structural engineer to assess the solution, who then approved the solution and successful certification of part of the device, respectively, in the assembly line.
