National and international transport of dangerous goods in Slovakia is exercised by the European Agreement concerning the International Carriage of Dangerous Goods by Road (ADR). All shipments covered by this agreement remain subject to national and international road traffic regulations, international road transport and international trade.

One of the most important characteristics of the vehicle, which characterizes the behaviour of the vehicle while driving, is the ability to reduce vehicle´s speed to stop point. Brake system requirements are set by statute ECE 13 and each EU Member State is obligated to implement them into their legislation. The brake system consists of a set of parts that serve to gradually reduce the speed of the vehicle to stop it and the system must keep it stationary if it has already been stopped. The quality of the brake discs and brake pads is decisive during braking as well as in removing heat from the brake area. This article discusses about the basic parameters compared during braking in changing the quality of brake components which impact road safety and the safety of passengers in vehicles.

The fuel consumption of road vehicles is influenced by many factors. One of them is the acclerator position. Measurment of the fue lconsumption on a rollingstand was done for the quantification of this effect. The tested vehicle was Kia Cee´d with a petrol engine. The measurments were done in laboratory condiditons to give higher accuracy. The results describe the degree of the effect of the accelerator position. They can be used for the determination the position considering to the actual output power of the engine and for the detrmination of the correctly driver behavour. The correctly usage of the accelerator contributes to the reduction of environmental burden of transport.
