GRVA | Session 25 | 18-22 May

22. During the consultations, the expert from Germany presented ECE/TRANS/WP.29/GRVA/2026/12, proposing provisions making the relevant Contracting Parties (respectively the Type-Approval Authorities) aware of an upcoming introduction of the system on the market within their jurisdiction and providing for the possibility to obtain further information from the granting Type-Approval Authority or the manufacturer. The experts from Germany and the United Kingdom proposed a revised proposal (GRVA-25-43). The experts from OICA presented an alternative proposal (GRVA-25-18) as well as ECE/TRANS/WP.29/GRVA/2026/13, on a separate topic, proposing to align the provisions on exchange of information through the database for the exchange of type approval documentation with those included in UN Regulation No. 171. The expert from the United Kingdom proposed improvements to the latter proposal (GRVA-25-29).

23. GRVA requested the secretariat to distribute GRVA-25-18 and GRVA-25-43 with official symbols for consideration at the September 2026 GRVA session.

24. GRVA adopted ECE/TRANS/WP.29/GRVA/2026/13 as amended by GRVA-25-29 and requested the secretariat to submit it to WP.29 and AC.1 as draft supplements to the original version and 01 series of amendments to UN Regulation No. 157 for consideration and vote at their November 2026 sessions. The expert from Germany withdrew ECE/TRANS/WP.29/GRVA/2026/12.
