Proposal for amendments to Regulation No. 13
Document GRRF/2017/11
5 July 2017

UN R13 allows for the exemption of certain vehicles from the requirement for electronic stability controls (footnote 12). This proposal (following proposals GRRF/2016/27 as amended by GRRF-82-03 and proposal GRRF-83-31) 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.
