During the consultations, the experts reviewed the proposal tabled by the expert from the United Kingdom of Great Britain and Northern Ireland (ECE/TRANS/WP.29/GRVA/2025/32), which aimed to ensure that where vehicles exhibit functionality meeting the definition of Automatically Commanded Steering Function (ACSF) of Categories B2 or E, they are required to comply with the correct series of UN Regulation No. 171.
