Proposal to consolidate definitions applicable to both Part I and Part II into a single chapter, add component and separate technical unit requirements to Rear-View Camera Systems and Detection Systems, establish requirements for software update references and identification, and merge amendments from Supplements 1–6 into the original text. Current type approvals remain valid. Changes do not affect stringency or content requirements.

Proposal to add Component and Separate Technical Units (STU) approvals regulatory supplement to UN R158 for devices for means of rear visibility or detection. The changes do not affect the content stringency and keep current UN R158 type approvals valid. The proposal replaces the complete UN Regulation text due to the number of changes required, incorporating text merged from Supplements 1 to 6 into the original text, with tracked changes and comments marking modifications outside the direct scope of the SIG-C&STU typical for clarity, corrections or consistency items which shall not affect stringency.

Proposal to add component and separate technical unit approvals regulatory supplement to UN Regulation No. 158. The changes do not affect stringency and keep current type approvals valid. The proposal replaces the complete regulation text and includes definitions, requirements for close-proximity rear-view mirrors, rear-view camera systems, and detection systems for vehicles of categories M₁–M₃ and N₁–N₃. Field of vision requirements, system activation, driver interface specifications, and test procedures are specified, with backing event duration defined as meeting speed of 16 km/h, distance of 10 meters, or duration of 10 seconds.

Proposal to insert new title establishing three parts of UN R159 (vehicles with regard to Moving Off Information System, vehicles with regard to installation of approved type systems, and Component or Separate Technical Unit), amend contents and definitions to add Component and Separate Technical Unit approval routes, insert new Part I establishing specifications and test procedures for vehicles, insert new Part II establishing specifications and test procedures for vehicles with approved type systems, insert new Part III establishing specifications and test procedures for Component or Separate Technical Unit types, amend approval provisions to accommodate three approval types, renumber existing paragraphs, and insert new Annexes 1 through 7 with communication and information documents for each approval type.

Proposal to insert a new title comprising three parts for vehicle approval and component/separate technical unit (STU) approval; amend the contents page; insert new definitions for approval types, vehicle types, components, STUs, and representative test setups; add application and approval procedures for the three approval routes; renumber and restructure paragraphs 5 through 12 as parts I, II, and III; insert new part I specifications for vehicles with moving off information systems; insert new part II specifications and test procedures for vehicles with approved components or STUs; insert new part III specifications and test procedures for components and STUs including detection, control, and human-machine interface requirements; insert new annexes 2 through 7 containing communication and information documents for each approval type; and amend former annexes 2 and 3 renumbered as annexes 8 and 9.

Proposal to insert new title, amend the Contents page, modify para. 0.1. to add reference to footnote 1 defining vehicle categories, amend paras. 0.3., 0.6., 0.8., 0.8.1., and 0.8.2., insert new para. 0.9. explaining Supplement 4’s introduction of Component and Separate Technical Unit approval routes, amend paras. 1.1. to 1.3. to reflect three-part approval structure, amend and insert paras. 2.1. to 2.37. to define approval types and representative test setup, amend paras. 3.1. to 3.3. to address application procedures for all approval types, amend paras. 4.1. to 4.78. to specify approval grant conditions and marking placement for each type, insert new paras. 5. to 7.2.4.6.2. to establish Part I vehicle specifications and test procedure, Part II installation specifications and test procedure, and Part III Component or Separate Technical Unit specifications and test procedure, amend paras. 78. to 121. for modification and conformity of production, amend Appendix 1 and Annexes 1 to 7, and amend former Annexes 2 and 3 (renumbered as 8 and 9).

Proposal to introduce provisions for type approval of Moving Off Information System Component or Separate Technical Unit, establishing three approval routes: Part I for vehicles with integrated systems, Part II for vehicles with approved components or units installed, and Part III for component and separate technical unit approvals. The regulation requires systems to detect pedestrians and cyclists in the forward blind spot during potential moving-off manoeuvres and low-speed manoeuvres at speeds up to 10 km/h, providing information signals and collision warnings. Automatic deactivation occurs upon malfunction or sensor contamination; manual deactivation is permitted through intentional driver actions. Vehicles of category Y and category X without manual on-board operation are exempted. Testing includes static crossing tests, longitudinal stopping and moving-off cyclist tests, failure detection, and automatic deactivation verification.

Proposal to introduce provisions for type approval of Moving Off Information System Component and Separate Technical Unit. The supplement adds Part III to UN R159 establishing approval requirements for MOIS Components and STUs, modifies Part I to align with the new component-based approval pathway, and adds Part II to govern vehicles installing previously approved Components or STUs. Manufacturers may choose between Component approval (largely vehicle-independent) or STU approval (tailored to specific vehicle families) to streamline market introduction of MOIS technology.
