40. The Secretary to the Working Party on Road Traffic Safety (WP.1) informed GRE that WP.1, at its March 2015 session, had continued considering the amendment proposals on Article 32 and Chapter II of Annex 5 of the Vienna 1968 Convention regarding lighting and light-signalling. The secretariat had been requested to prepare, for the next session, a new revision by incorporating amendment proposals submitted by IMMA. GRE recalled that, once finalized and approved by WP.1, these amendment proposals should be officially forwarded to the UN Secretary-General by one of the Contracting Parties to the 1968 Convention. The WP.1 Secretary reiterated his invitation to GRE experts to discuss this issue at the national level, with a view to finding a volunteer country.
