Dangerous goods are considered goods that can harm people's health, cause environment pollution or material damage. They have dangerous characteristics for human health and the environment, which are defined by law, other regulations and international contracts. By respecting the regulations we ensure safety of the participants in the transport and, on the other hand, safety of the property and the environment. The cause for the issuance of regulations were accidents that had been happening when unloading dangerous goods. Former regulations were short and simple, they contained all important measures that are included in today legislation (prohibition of joint loading-transport, special requirements at the unloading). In order to respect the regulations for the carriage of dangerous goods, in most cases were needed great accidents. Dangerous goods carriage should have special attention, careful selection of the transport vehicles and technical/technology manipulation tools. People who are in direct contact with dangerous goods should be especially educated. In the paper I will present the application of the ADR regulations during planning and implementation of the carriage of dangerous goods. I will reflect on the role of a logistic operator in the organization of dangerous goods carriage by road vehicles. I will name the example of organizing the goods transportion by ADR in the company "KOS Transporti".
