16. The expert from Korea introduced the issue (GRSP-57-24) concerning the extension of mandatory fitting of safety-belt reminders (SBR) to rear seats as a basis to increase the low wearing rates of safety-belts in the rear seats in Asian countries. Referring to GRSP-57-24, the expert from Japan introduced GRSP-57-17-Rev.2, jointly prepared with the experts from EC and Korea, providing the basis for a proposal of amendments to the UN Regulation to introduce SBR in the rear seats. GRSP noted that the United States of America was developing a notice of proposed rulemaking (NPRM) on the same matter that probably would be publicly available by the end of 2015. The expert from OICA argued that the issue of wearing rate should have a multidisciplinary approach including education and that a standalone technical solution would not solve the issue, but add burden costs to consumers. The expert from Germany added that the great wearing rate of safety-belts in his country was successfully achieved thanks to strong law enforcement. The expert from the Netherlands made a similar statement. The expert from France supported the validity of the request. However, he raised a study reservation and confirmed the need of a robust cost-benefit analysis and rationale to justify the proposal. The expert from Denmark supported the proposal, though he questioned the proposed deactivation time duration of SBR and the exclusion of multi-purpose vehicles from the scope of the proposal. Finally, GRSP agreed to resume discussion on this issue at its December 2015 session and requested the secretariat to distribute GRSP-57-17-Rev.2 with an official symbol.
