8 Aug 2017 Proposal for a draft amendment to Regulation No.53 (IMMA) GRE/2017/27 2017-08-08 Proposal to explicitly allow direction indicators to be activated when the motorcycle engine is stopped in order to signal the vehicle status. Some motorcycles currently offer this feature; however, it is not clear whether the scope of Regulation No. 53 covers and allows this function. IMMA
10 Feb 2018 UN R53: Proposal for a draft amendment (IMMA) GRE/2018/25 2018-02-10 Proposal to clarify the text with regard to the activation of the direction indicators when the motorcycle engine in order to signal the vehicle status. The proposal would specify the purposes for which indicators may be activated:<ol class="alpha"><li>To show the vehicle status (e.g. locking system) when the vehicle is parked;</li><li>To allow the driver to recognize the presence of his/her own vehicle from a certain distance by remote control;</li><li>In case of keyless entry system and of the driver having lost the key fob while riding - to inform the driver that he/she no longer has the key fob and that the vehicle will soon become unable to restart.</li></ol> IMMA

The document outlines provisions applicable to all amendment series, including that Contracting Parties may grant type-approvals according to any preceding series and shall continue granting extensions of existing approvals. For the 05 series of amendments, specific dates establish when Contracting Parties shall accept or refuse type-approvals, with exceptions for equipment, parts, and unaffected vehicle systems. IMMA
8 Jun UN R53: Updated 05 series of amendments baseline document (IMMA) SLR-78-09 2026-06-08 This document proposes draft provisions for a 05 series, updating the previous baseline (SLR-71-07). Key changes include simplification of definitions by referencing UN R48 where applicable; consolidation of geometric visibility requirements with uniform formatting; incorporation of electric vehicle (EV) provisions; inclusion of rear-end collision alert signal (RECAS); replacement of legacy terminology with hyphenated forms (e.g., "direction-indicator lamp," "type-approved"); use of scientific notation for luminous intensity values; and reduction of transitional provisions to retain only the 05 series requirements. Annex 3 has been reserved and deleted. The regulation applies to the installation of lighting and light-signalling devices on motorcycles and prescribes mandatory and optional devices with specifications for position, geometric visibility, orientation, electrical connections, and tell-tales. Transitional provision dates remain undecided. IMMA

Option 1 retains the current form without the series number. Option 2 adopts the current Baseline document style. Option 3 adds an area in the comment section. Option 4 invites other ideas. Feedback is requested on which option should be adopted. IMMA
