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.

The article is about the possibilities to diagnose the technical state of transfer mechanism of road motor vehicles. The diagnostic is done on a performance dynamometer, which measures the resistance of transfer mechanism during the coasting of rolling mass. The resistance makes itself felt like power losses by the movement of vehicle, which afects directly dynamical characteristics and fuel consumption. By the measurement we can quantify its value, what is the sign of the technical state of the mechanism.

Automobile shock absorbers are an important part of the vehicle suspension, which directly affect the driving comfort and maneuverability. Therefore, they direct impact on the safety of their operations. Wrong technical condition of the car shock absorbers can cause extension of braking distance by up to 20%. In actual service station practice, the automotive shock absorbers are diagnosed by several methods. This article presents the results of measurements of automotive shock absorbers on various diagnostic devices. During testing, on the vehicle there were replaced shock absorbers and they were compared with the results of the technical condition before and after the exchange.

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.
