Document WP.29/343 is the “Status of the 1958 Agreement” which provides the current listing of UN Regulations, Contracting Parties applying each regulation, technical services authorized to conduct testing under each regulation, and so on. Revision 3 of the 1958 Agreement and UN R0 on International Whole Vehicle Type Approvals change the status document because Contracting Parties may accept earlier versions of UN Regulations and IWVTA approvals may be partial or universal based upon acceptance of specific regulations and/or versions. This submission from the WP.29 Secretariat provides guidance on how these changes will be reflected under the status document.
