Proposal to amend UN R158 based on GRSG-131-36. The supplement renumbers the introduction’s first paragraph to 0.1, describing the regulation’s purpose for rear visibility and detection devices. New paragraphs 0.2–0.2.3 address vehicles of categories X and Y, including exemptions for automated driving systems and manual operation modes. Paragraph 1.4 is amended to exempt category Y vehicles and category X vehicles without on-board manual modes. Amendments modify paragraphs 5.4.1, 12.4, 15.1.3, 15.1.4, 15.2.2, and Annex 9, paragraph 1.3.3.2, addressing safety concepts, rear-view field vision requirements, and vehicle load specifications.

The Special Interest Group on Component & Separate Technical Unit (SIG-C&STU) for the Supplement of UN Regulations 151, 158, 159 and 166. Proposal adds Component and Separate Technical Units (STU) approvals requirements.

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.

Proposal to amend and supersede ECE/TRANS/GRSG/2026/11. Supplement 6 to UN R158 amends provisions for means of rear visibility and detection. The Regulation is amended to account for vehicles of categories X and Y. Vehicles of category Y and vehicles of category X without manual mode intended to be operated on-board are exempted. Vehicles equipped with Automated Driving Systems must comply when operated manually by a driver on-board. Alternative provisions apply for category X vehicles with manual operation other than seated in driver’s seat.

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.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to exempt vehicles of subcategories X and Y from the requirements and limit the requirements for other vehicles equipped with an ADS and when an ADS feature is active.
