92. The representative of OICA presented (GRVA-17-47) their latest amendment proposal (ECE/TRANS/WP.29/GRVA/2023/23) to the Electronic Stability Control testing procedure to take account for vehicles with low steering gear. 93. The representative of the United States of America reminded GRVA that the original testing procedure was globally harmonized and part of UN GTR No. 8. He did not identify technical issues with the proposal. He asked that field data were collected to support a potential similar amendment of the testing procedure under the 1998 Agreement. 94. GRVA requested the secretariat to transmit ECE/TRANS/WP.29/GRVA/2023/23 as draft Supplement 6 to UN Regulation No. 140 to WP.29 and AC.1 for consideration and vote at their March 2024 sessions. GRVA also agreed that data is collected to support a similar workstream under the 1998 Agreement. 95. The representative of Czechia suggested GRVA to share views, at one of its next sessions, on the safety of steering systems with a low gear ratio in the context of UN Regulation No. 79. 92.
