Different criteria during the openings of new stations for technical inspection of vehicles lead to unfair competition, and thus to “destroying“ the reputation of stations for technical inspection of vehicles as well as the staff. Statistical data of traffic accidents in BiH are shown, too. For this purpose was conducted a correlation analysis of dependencies between variables, and in order to determine the functional dependence was applied the method of regression analysis. At the end, in addition to measures for improving these operations conclusions will be given. Keywords: Station for technical inspection of vehicles, traffic accident, vehicle validity. 1. INTRODUCTION The causes of traffic accidents are classified in three main groups: human, vehicle and road. Always actual question is how much certain factors of the individual groups influence the emergence and consequences of traffic accidents. Influential factors related to the vehicle and its validity are noted as very important and are the subject of many measures which are carried out in order to improve traffic safety. System of control of technical validity of vehicles in BiH is performed by stations for technical inspection of vehicles divided into three subsystems, or subsystems that are in the two entities and one district. Based on data from all stations for technical inspection during previous five years, an analysis of impacts on traffic safety was done. In addition was made a comparison of results in neighboring countries. Results of the analysis are applied in making decisions that will improve the level of technical validity of vehicles, and therefore to traffic safety. 2. CONTROL SYSTEM OF VEHICLES VALIDITY IN BOSNIA AND HERZEGOVINA In Bosnia and Herzegovina control system of technical vehicles validity includes stations for technical inspection of vehicles (STPV) in entities. Main features of the functioning of the system are given through the checked vehicles, participation in the total number of inspected vehicles. Stations for technical inspection of vehicles represent a small test lab which should ensure technical validity of vehicles as one of the essential prerequisites for the safety of all road users with pre- equalization of legislation in this area and to ensure the quality of work of the stations and financial viability of the stations 2 . Quality supervision over the work of the stations, professional and administrative supervision can bring positive results to thereby ensure the implementation of applicable laws. Each vehicle involved in the traffic on the roads has to be technically valid, in other words, must meet the technical inspection.
