53. The Secretary to AC.1 reported on the progress in preparing Revision 3 of 1958 Agreement, including UN Regulation No. 0 on IWTA (ECE/TRANS/WP.29/2014/53 and WP.29-162-04), as well as the proposed revised guidelines for supplements and series of amendments to UN Regulations (WP.29-162-18) whose main elements are as follows:

a) Contracting Parties may apply former versions of UN Regulations, “engraved in stone”;

b) establish common date (e.g. 1 September each year) of entry into force of new series of amendments to UN Regulations;

c) only one new series of amendments per year would be allowed;

d) in case of several series of amendments in force, for every supplement the respective GR and WP.29 should indicate the series of amendments it refers to. The secretariat should prepare separate documents for each series of amendments for adoption by WP.29 and AC.1;

f) the guidelines for transitional provisions established by WP.29 (ECE/TRANS/WP.29/1044/Rev.1) would be amended accordingly.

54. GRE took note of the above information and expressed no objections to setting the common annual date of entry into force of new series of amendments on 1 September.

55. The experts from Finland and Japan presented ECE/TRANS/GRE/2014/12 amending UN Regulation No. 4 (Rear registration plate lamps) for the purposes of IVWTA and introducing provisions for illuminating registration plates of five different sizes (categories) which are currently used around the world. When applying for the first approval or at a later stage, the applicant should indicate the category(ies) which the device is intended to illuminate. GRE adopted the proposal and requested the secretariat to submit it to WP.29 and AC.1 for consideration at their November 2014 sessions as draft Supplement 18 to UN Regulation No. 4.
