GRSP | Session 78 | 1-4 Dec 2025

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.
