                UN Regulation No. 168

         7.1.              The technical requirements of United Nations Regulation No. 168 - Uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to real driving emissions (RDE).

                       Note: United Nations (UN) Regulation 168 - Uniform provisions concerning the approval of light duty passenger and commercial vehicles with regards to real driving emissions (RDE) (ECE/TRANS/WP.29/2023/77) was adopted as a new UN Vehicle Regulation by the Administrative Committee for the United Nations 1958 Agreement Concerning the Adoption of Harmonized Technical United Nations Regulations for Wheeled Vehicles, Equipment and Parts which can be Fitted and/or be Used on Wheeled Vehicles and the Conditions for Reciprocal Recognition of Approvals Granted on the Basis of these United Nations Regulations (the UN 1958 Agreement) on 21 June 2023. Once this regulation officially enters into force under the UN 1958 Agreement, vehicles complying its technical requirements of this regulation will be accepted as complying with this vehicle standard.
