The document discusses transitional provisions for UN R10.07 series amendments, which entered into force June 2025. Contracting Parties shall not refuse type approvals under the 07 series amendments. As from 1 September 2029, Contracting Parties need not accept type approvals under preceding series first issued after that date, but shall continue accepting those first issued before that date for vehicles, vehicle systems, equipment, and parts not affected by changes introduced by the 07 series amendments. The document references ECE/TRANS/WP.29/1044 rev3 for general transitional provision guidance. Nearly all vehicles and ESAs will not be granted extensions for UN R10.06 after 1 September 2029, except those complying only with broadband emissions.
