The revised fourth edition of the Blue Book continues to provide precise information about the World Forum for Harmonization of Vehicle Regulations (WP.29) as serviced by the ECE Sustainable Transport  Division: on its history, its administrative and legal framework as a guide for users, and on the three Agreements.

WP.29 administers the three major international United Nations Agreements on motor vehicles: the 1958 and 1998 Agreements on regulations for the certification of new vehicles, including performance requirements, and the 1997 Agreement on rules for periodical technical inspections of vehicles in use.

The Blue Book also provides guidelines for the accession by countries to these agreements.
