34. GRPE endorsed the proposal of the HDH Chair to widen the mandate of the group to include amendments aligning UN GTR No. 4 with UN GTR No. 11. GRPE requested the sponsor (EU) to submit an informal document illustrating the choice to widen the mandate to the March 2014 session of WP.29 and AC.3, amending document ECE/TRANS/WP.29/AC.3/29.

89. The representative of EU confirmed that the IWG would present a formal proposal for amendments to the UN GTR for consideration by GRPE at its June 2014 session and expected that AC.3 would adopt it at its November 2014 session. He presented WP.29-162-08 requesting an extension of the GRPE mandate on developing amendments to the UN GTR including the alignment of UN GTRs Nos. 4 and 11. AC.3 adopted the request and invited the secretariat to prepare the corresponding AC.3 authorization.

93. The representative of EU reported on the IWG which had completed its mandate in due time. The representative of the United States of America proposed that some additional work should be envisaged. AC.3 agreed to first consider, at its November 2014 session, the draft Amendment 3 adopted by GRPE in June 2014 and, then, to investigate remaining issues to define a mandate for a second phase for the IWG. AC.3 reconfirmed the adoption of ECE/TRANS/WP.29/AC.3/38 on the extension of the IWG mandate.
