Unece 58 Agreement
Most countries, even if they do not formally participate in the 1958 agreement, recognize the provisions of the United Nations and reflect the content of UN regulations in their own national requirements, or authorize the importation, registration and use of UN vehicles or both. The two main exceptions are the United States and Canada (excluding lighting requirements); UN regulations are generally not recognized and UN compliant vehicles and equipment are not permitted for importation, sale or use in both regions unless they are considered to be in compliance with regional vehicle safety legislation or restricted non-traffic (e.g. B car show screens).  The agreement on the establishment of comprehensive technical rules for wheeled vehicles, equipment and parts that can be mounted and/or used on wheeled vehicles, or the 1998 agreement, is a subsequent agreement. Following its mission to harmonize vehicle regulations, the EEC-UN resolved the main problems (administrative provisions relating to type reception against self-certification and mutual recognition of receptions) that prevented countries not signatories to the 1958 agreement from participating fully in their activities. The first signatories to the 1958 agreement included Italy (28 March), the Netherlands (30 March), Germany (19), France (26), 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 1958 agreement is based on the principles of type reception and mutual recognition. Any country that adheres to the 1958 agreement is entitled to review and approve the design of a product regulated by a manufacturer, regardless of the country in which that component was manufactured. Each design of each manufacturer is counted as a single type.
Once a member country has granted a reception by type, any other member country is required to make a requirement and to consider that vehicle or its equipment to be legal for importation, sale and use.
