Analysis of the impact of the use time of n1 motor vehicles on the economic efficiency of their maintenance

The specificity of the use of N1 motor vehicles constantly raises a lot of controversy, and in the area of legal conditions there are still a number of ambiguities, which affects the existence of rather negligible amount of literature on this subject. Every month there is new information regarding the statistics of the Main Road Transport Inspectorate about the results of N1 category motor vehicles inspections. For several years, the percentage of vehicles with a load exceeding their permissible capacity in relation to the category N1 vehicles inspected has remained on average at the 93% level (table 1) [19]. It is a fact that the Road Transport Inspectorate usually checks heavy goods vehicles over 3.5 tons, while N1 category vehicles only when it considers that there is a clear suspicion of committing a specific offense. The number of vehicles inspected is negligible, but the percentage ratio of vehicles with a load exceeding their permissible load capacity of up to 3.5 tons may indicate the existence of a complex problem that should be subject to detailed analysis. Therefore, it becomes justified to be interested in the subject of increasing the profits from operation of the N1 category motor vehicles.
