47. The expert from Australia introduced the status report (GRSG-128-37) of the Informal Working Group on Driver Drowsiness and Distraction Warning Systems (IWG DDADWS). He further introduced the Terms of References (ToR) of the IWG (GRSG-128-38-Rev.2). The experts from CLEPA and OICA questioned the possibility of completing the IWG activities by 2025 and 2026. The expert from India expressed his interest in actively participating in the IWG activities. GRSG noted the intention of IWG to develop two UN GTRs at the same time. GRSG noted that the development of UN GTR should follow the administrative procedures of the 1998 Agreement. Therefore, it was noted, as a first step, that an authorization to develop the work from one or more Contracting Parties (as sponsor(s) of the development of the UN GTRs), should be submitted to the Executive Committee of the 1998 Agreement (AC.3) for endorsement. GRSG noted that the ToR contained the clause that UN GTRs would be developed subject to endorsement by AC.3. Therefore, GRSG adopted GRSG-128-38-Rev.2 as reproduced in annex V to this report, pending endorsement by WP.29. Moreover, GRSG recommended that the expert from Australia coordinate with interested Contracting Parties to the 1998 Agreement, to submit the above-mentioned authorization (possibly at the March 2025 session of AC.3) to allow the parallel development of UN GTRs.
