The representative of Germany proposed (GRVA-23-04) to reinstate in UN Regulation No. 157 on Automated Lane Keeping System (ALKS) the obligation for a granting Type-Approval Authority to inform each other Contracting Party (respectively the Type-Approval Authority) before issuing the Type-Approval for which the manufacturer has expressed the intention to introduce ALKS in that country and has therefore provided evidence of compliance with the relevant national traffic rules (according to Annex 1-Appendix 2).
