Proposal to amend UN R158 to include category O vehicles (trailers) within the scope of regulations for devices enabling driver awareness of vulnerable road users during reversing. The amendment aims to reduce safety risks to vulnerable road users when category O vehicles reverse. Amendments modify title, paragraphs 1.1, 1.2, 1.4, 12.3, 12.4, and Annex 4, and introduce transitional provisions starting from September 2028. Justification includes casualty data showing seven fatalities and 15 serious injuries over 10 years from vehicles towing trailers reversing into vulnerable road users, plus a coroner’s recommendation for reversing cameras on all vehicles. |

The Special Interest Group on Component & Separate Technical Units (SIG-C&STU) proposes amendments to UN R159, UN R158, UN R151, and UN R166 to add Component and Separate Technical Unit approvals. For UN R159, the proposal introduces a universal functional block structure separating Detection, Control, and Human Machine Interface functions, with Component or Separate Technical Unit fulfilling Detection and Control as minimum requirements. The regulation is restructured into three parts: vehicles without approved Component or Separate Technical Unit, vehicles with approved Component or Separate Technical Unit, and Component or Separate Technical Unit specifications. UN R158 adds new devices for Rear-View Camera Systems and Detection Systems to Part I, with corresponding installation requirements in Part II. The group requests written comments within four weeks and plans submission to Working Party 29 in June 2026. |
