The core of the Forum`s work is based on the „1958 Agreement“ officially titled „Agreement on the Adoption of Uniform Technical Rules for Wheeled Vehicles, equipment and parts that can be mounted and/or used on wheeled vehicles and the conditions for mutual recognition of permits issued on the basis of these requirements“ (E/ECE/TRANS/505/Rev.2, amended on 16 October 1995). It will be a legal framework in which participating countries (contracting parties) agree on a common set of technical requirements and protocols for the reception of vehicles and components. These were previously referred to as „EEC-UN regulations“ or, less formally, „EEC regulations“ with regard to the Economic Commission for Europe. However, since many non-European countries are now parties to the 1958 agreement, the regulations officially refer to them as „UN regulations“.   In accordance with the principle of mutual recognition set out in the agreement, the type receptions of each party are recognized by all other contracting parties. adaptation of the 1958 agreement to technological progress, improved road safety and environmental protection and harmonization of environmental measures – regulations are amended by:…/Rev.X – a revision of the text that includes all the previous texts of the regulation in vigo. …/Amend.X – an amendment to the text of the current regulation or a new set of amendments to the regulation amending the registration mark…./Corr.X – a correction consists of editorial corrections of errors in the published text. Because the corrigendal is called „ab initio,“ the effective date indicates the date of its adoption by the AC.1 management committee. At present, it is not possible to design a single model of car that fully complies with the requirements of the United Nations and the United States, but it will be easier to develop the technology and both rules. Given the size of the U.S. auto market and the different marketing strategies in North America, unlike the rest of the world, many manufacturers produce vehicles in four versions: North American, A CEE Right-hand drive (RHD), UNECE Left-hand drive (LHD) and the rest of the world (for unregulated countries or countries with poor fuel quality. Among the first signatories to the 1958 include Italy (28 March), the Netherlands (30 March), Germany (19 June), France (26 June), Hungary (30 June), Sweden and Belgium.
Initially, the agreement only allowed the participation of the ECEC member countries, but in 1995 the agreement was revised to allow the participation of non-MEMBERS of the ERC. Current participants include the European Union and its member countries, as well as non-EEC-UN countries such as Norway, Russia, Ukraine, Croatia, Serbia, Belarus, Kazakhstan, Turkey, Azerbaijan and Tunisia, and even remote regions such as South Africa, Australia, New Zealand, Japan, South Korea, Thailand and Malaysia. The most notable non-signature of the 1958 agreement was that of the United States, which had its own federal motor vehicle safety standards and did not recognize UN-type receptions. However, both the United States and Canada are parties to the 1998 agreement. Vehicles and components of the United Nations specification that do not also comply with U.S. rules cannot therefore be imported into the United States without significant modifications. Canada has its own Canada Motor Vehicle Safety Standards, which roughly resemble the U.S. FMVSS, but Canada also accepts UN-compliant headlights and bumpers. The forthwhile comprehensive economic and trade agreement between Canada and the European Union could prompt Canada to recognize more UN rules as acceptable alternatives to Canadian rules.  Canada currently applies 14 of the 17 main EEC standards as authorized alternatives: exceptions for motorcycle controls and displays, motorcycle mirrors and electronic control of the stability of passenger cars.
