24. The expert from OICA introduced working documents ECE/TRANS/WP.29/GRSP/2025/42, GRSP/2025/45 and GRSP/2025/46 to allow putting the vehicle back on its wheels in case of overturning during the collision test in order to allow door openings as per paragraph 5.3.3. The opinions on this issue were divided. The experts from the Republic of Korea, Germany, the Kingdom of the Netherlands and Japan argued that overturnings were an artifact of the test and were highly dependent on the tires used and the friction coefficient of the floor, both of which were not part of the test specifications. They therefore interpreted that the current text already allowed putting the vehicle back on its wheels and were in favor of the proposal as a clarification. On the other hand, the experts from Spain, France and the United Kingdom argued that being able to open the doors after the crash was an integral part of the test and their current interpretation was that putting the vehicle back on its wheels was not allowed. GRSP agreed that it was important to continue discussing this issue in the next session in order to ensure a harmonized interpretation across different type approval authorities.

17. The expert from OICA introduced informal document GRSP-79-21 amending ECE/TRANS/WP.29/GRSP/2025/42, 45 and 46, to allow putting the vehicle back on its wheels in case of overturning during the collision test in order to allow door openings. All experts that spoke agreed with the proposal except the expert from France, who raised concerns with regard to putting the vehicle back on its wheels after UN Regulation No. 95 impact to test door opening at the opposite side of the impact, as this may not represent real life accidents. He requested to have more time to analyse the issue with rescue services, OICA, and other Contracting Parties, and to come back at the next session. GRSP adopted informal document GRSP-79-21 (as reproduced in annex III), with the above reservation from France, and requested the secretariat to submit it as proposals for supplement 3 to 04 series of amendments, supplement 5 to the 05 series of amendments and supplement 3 to the 06 series of amendments to UN Regulation No. 95 to the June 2026 sessions of WP.29 and the Administrative Committee of the 1958 Agreement (AC.1).
