33. Upon the request of WP.29, GRB considered the Draft General Guidelines for United Nations regulatory procedures and transitional provisions in UN Regulations (ECE/TRANS/WP.29/2017/107) prepared by IWG IWVTA. The expert from OICA pinpointed provision 6.1 (in square brackets) which stipulated that “a Contracting Party may apply additional national provisions for vehicle characteristics not covered by the scope of a UN Regulation”. According the expert, this provision seemed to be counterproductive for the harmonization of vehicle Regulations and should be clarified. The Chair invited GRB experts to consider the Draft Guidelines and to submit their comments, if any, to the secretariat and/or to IWG IWVTA by 20 October 2017.
