In recent years, Poland has seen a dynamic increase in the number of vehicles on the road. Vehicles participating in road traffic come from both the domestic market, some registered as new, and are imported from foreign markets. The latter are mainly imported from Western Europe and from the American market. Vehicles imported onto the domestic market are several years old and quite often considerably worn out. On the other hand, vehicles from the American market are relatively new and sometimes damaged as a result of road incidents. The aim of this work is to perform a comparative analysis of the results of vehicle technical tests. Research was conducted at two regional vehicle inspection stations over three consecutive years. As part of this analysis, questions about the number of successful and unsuccessful technical tests were answered by the test type. In addition, the number of vehicles using the services of the various stations was evaluated, and the number of vehicle technical tests was analysed by the energy supply of those vehicles. This was followed by the comparison of the test results with the nationwide data in the Central Register of Vehicles and Drivers. A decrease in the number of unsuccessful vehicle tests was noted. Moreover, a greater number of tests of electric vehicles has been noted recently, which may be advantageous to the environment in the future.
