GRSP considered GRSP-69-09, concerning the interpretation of the expert from the Netherlands on the way “one belt route” defined by the current text of UN Regulation No. 129 (Enhanced Child Restraint Systems). He also requested guidance to GRSP how to deal in the future with questions of this kind. GRSP agreed on the interpretation provided by the expert from the Netherlands:
""one belt route" shall be strictly interpreted, only asymmetrical attachments can still be regarded as “one belt route”
GRSP agreed that such an interpretation would not need to amend the current text of UN Regulation No. 129. Moreover, GRSP agreed that such decision would be reported orally by the Chair of GRSP at the June 2021 session of WP.29 as well as the request of guidance to address issue of interpretations of this kind in a more coordinated way in the work of WP.29 and its subsidiary bodies.
