Latest Changes to WP.29 Regulations
The following table provides a listing of regulatory texts published during the past six months. These texts are the consolidated versions of the changes published by the United Nations based upon the proposals formally adopted by WP.29. Because the original adopted proposals often include last-minute amendments or corrections, the UN prepares these consolidated versions of the final approved texts as a convenience. The original documents as considered during the adoption votes in WP.29 legally remain the official texts.
