Proposal developed by the GRSG chair, OICA, and the UK to align the transitional provisions of the 01 series of amendments to UN Regulation No. 121 (document WP.29/2012/30, presently pending before WP.29 and awaiting parallel amendments from the GRRF for UN R13 and 13-H) with those of UN R13 and 13-H.

Proposal for transitional provisions concerning the electronic stability control telltale and approval markings related to UN R121.

Correction to paragraph 12.3 so it reads " As from 24 months after the date of entry into force of the 01 series of amendments, Contracting Parties applying this Regulation shall grant type approvals only if the vehicle type to be approved meets the requirements of this Regulation as amended by the 01 series of amendments."

Proposal to update the transitional provisions of UN R13, including provisions for extensions of type approvals granted according to the antecedent requirements of the original approval. These amendments also relate to the transfer of brake-related telltale provisions to UN R121. The proposal also would clarify and align UN R13 with UN R107 on bus construction with regard to the exemption of articulated buses and coaches from the requirements for vehicle stability equipment. These proposals are based on documents GRRF/2014/7 and GRRF-76-20 as amended and reproduced in Annex II of the report of the GRRF on its 76th session.
