Resumen
In Poland, the major share of operational costs of a road carrier constitute of fuel costs, costs of outsourced services and remunerations. The mentioned cost groups together contribute to over 80% of the prime costs. As a result, these costs have a major influence on the performance of Polish road carriers. As research results show, the financial situation of the road carriers in Poland is poor. On average, the return on sales in road transport services reaches the level of 1.5?3.0%, and in case of international road transport services it amounts to 5%. In terms of acknowledged standard sit is merely a sufficient level of return. Unfortunately it is possible for the performance to deteriorate due to the implementation of minimum wage rates for drivers in some EU countries and due to the implementation of new regulations proposed on May 31st 2017 in the EU?s Mobility Package, concerning seconded workers.
