Abstract
Working conditions for drivers in the European Union and Slovakia are governed by European and National regulations. Regulations lay down rules on driving times, breaks and rest periods for drivers of lorries and buses to improve working conditions and road safety. There is no doubt that with increasing freight performance, the number of carriers and vehicles in the field of road freight transport is also increasing. Therefore, in connection with the current EU legislation, which aims to increase road safety, attention is paid to adopting regulations for all road haulage operators and carriers. The purpose of this paper is to show difference between road freight transport performed by vehicles up to 3,5 tonnes and vehicles transporting goods where the maximum permissible mass of the vehicle, including any trailer, or semi-trailer, exceeds 3,5 tonnes.
