Proposal from Germany to introduce a new Annex 23 into UN Regulation No. 13 covering special additional requirements for trailers of category O2 without pneumatic connections and equipped with service braking systems with pneumatic energy storage devices. In addition, the document proposes to further amend braking requirements for trailers under Regulation No. 13 and 13-H to address these new braking systems.

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls. This proposal seeks to clarify the scope of the exemptions to include any special purpose vehicle with a non-standard chassis. The change was prompted by a modified vehicle where use of ESC was not feasible, but where the current UN R13 language left doubt as to whether the ESC requirement was applicable.
