ADR regulation was developed in line with the recommendations of the United Nations (UN) to establish a common safety framework for the transport of dangerous goods by road.Although it began as an agreement between European countries, it has now also been adopted by several countries in Asia and North Africa, significantly expanding its scope.

ADR regulates all aspects of the land transport of dangerous goods, including packaging, labeling, documentation, vehicle signage, as well as loading, unloading, and temporary storage. These provisions apply to both international and national transport, as long as the country in question is a party to the agreement.

One of the key elements of the regulation is the clear definition of the obligations and responsibilities of all stakeholders involved: carriers, loaders, consignors, consignees, as well as manufacturers of packaging, containers, tanks, and other related equipment. The main objective is to minimize risks to people, property, and the environment.

The ADR contains a detailed list of dangerous goods coded according to UN classification, along with the technical and legal requirements applicable to each. This list allows products to be identified and the appropriate safety measures applied according to their hazard level.
