Proposal to insert definitions for Software Identification Number, insert requirements for manufacturers to provide necessary information allowing the Technical Service to uniquely identify hardware and software configurations, insert provisions allowing vehicle manufacturers to apply for new approvals to differentiate software versions for registered versus new vehicles, amend production discontinuation provisions to clarify that cessation is not deemed definitive if the manufacturer intends to obtain subsequent extensions for software updates of vehicles already registered in the market, renumber and insert new items in approval communication annexes regarding software identification and software updates including RxSWIN, and insert provisions allowing vehicle manufacturers to obtain new approvals for software version differentiation across multiple UN Regulations (13, 13-H, 79, 89, 130, 131, 139, 140, 152, 155, 156, 157, 171, 175, and 178).

Status report on activities of the IWG on CS/OTA since the 25th GRVA session. The IWG reviewed proposals for amendment of UN R155 and its interpretation document for multi-stage vehicles, proposals for approval-authority arrangements and Certificates of Compliance for UN R155 and R156, proposals integrating software identification and update text across several UNRs outlined in RE.3, component and STU approval concepts, and remote operation and automated driving systems. The IWG proposes updating regulatory text and interpretation documents for UN R155, revisions to software identification and update text across several regulations, and revised Terms of Reference for a mandate till November 2029.

Agenda for the 132nd session of the Working Party on General Safety Provisions, scheduled 28 September to 2 October. The session will address amendments to UN R107, UN R43, UN R46, UN R67, UN R110, UN R116, UN R161, UN R162, UN R163, UN R151, UN R158, UN R159, UN R166, UN R121, UN R122, UN R125, UN R0, UN R160, UN R169, UN R58, UN R105, UN R73, UN R39, and UN R58. The session will also cover vehicle automation, periodical technical inspections, driver distraction and drowsiness warning systems, and door open warning systems.

Proposal to introduce a unified Position Code (X-Y) for all seating positions, add seven new mandatory data elements for driver operation and seat-track position to Annex 4 Table 1, and harmonize ADAS status enumerations into one unified set eliminating fragmented and inconsistent wording across system entries.

Proposal to add footnote 1 to para. 6.2. defining transparency as requisite for the driver’s forward field of vision, for the driver to see and to be seen, and insert new para. 6.3. stating that safety glazing located in a position requisite for driving visibility may not be treated such that it limits or restricts the visibility of the driver from outside, for example by applying a mirror or chameleon effect, with minimum light transmittance provisions as described in Annex 24 applying from both directions.

Proposal to add footnote 1 to para. 6.2. to clarify that safety glazing materials must be sufficiently transparent as a requisite for the driver’s forward field of vision, for the driver to see and to be seen. The amendment aims to clarify possible safety concerns to ensure that the driver can be seen from outside and does not introduce new provisions but clarifies the intent of existing provisions.

The Czech Republic requests guidance from GRSG on whether automatic activation of a dedicated “Call for Help” signal with higher flashing frequency, instead of the standard hazard warning signal following severe vehicle impact linked to UN Regulation No. 144 trigger criteria, conflicts with existing post-crash safety requirements under GRSG competence. A formal proposal to introduce this new signal within UN Regulation No. 48 has been submitted to GRE under document ECE/TRANS/WP.29/GRE/2026/2.

Proposal to amend para. 2.12. to replace the reference to ISO [CD] 19206-4 with ISO 19206-4:2020 and specify an adult bicyclist target, and amend para. 5.3.2. to replace the reference to ISO [CD] 19206-4:2018 with ISO 19206-4:2020, clarify requirements for demonstrating BSIS performance for smaller bicycles and smaller bicyclists differing by up to 36 per cent from nominal dimensions for the adult bicyclist target through physical testing using a child bicyclist target, simulation sufficiently validated by physical testing, or another documented means sufficiently valid and accurate to establish BSIS performance for a child bicyclist target.

Proposal to amend para. 5.12. to require the manufacturer’s management system encompassing cyber security to comply with the relevant requirements of UN R155 with regard to total distance indicated and total distance values, and to require threat and associated vulnerabilities to be analysed according to the management system with regard to total distance indicated and total distance values, with proportionate mitigations implemented including or equivalent to mitigation 7 referred to in Annex 5, Part B, Table B5, threat 20.4. of UN R155. The proposal aligns odometer anti-tampering and security management requirements with UN R155 and clarifies that mitigating measures must be implemented regardless of risk value assessment.

Letter of support from the International Federation of Pedestrians and the European Cyclists Federation for the proposal for Supplement 14 to the 01 series of amendments to UN R43. The submission supports efforts to clarify regulations and ensure that windows within the driver’s forward field of vision meet minimum light-transmission requirements when viewed from both inside and outside the vehicle, and opposes treatments or tints that prevent people outside the vehicle from seeing the driver.

Final draft proposal to:

• Amend para. 1.4. to clarify recording obligations for data elements when sensors lack design capability to meet format requirements,
• Amend para. 2.20. to define engine throttle as driver-requested acceleration torque demand,
• Amend para. 2.73. to define trigger activated,
• Amend para. 5.4.3. to clarify crash test requirements and specify data retrievability after impacts of severity levels set by UN Regulations Nos. 94, 95 or 137,
• Insert new paras. 12.12. through 12.17. establishing transitional provisions with dates from entry into force through 1 September 2035,
• Amend Annex 4 Table 1 to add data elements including occupant size classification, vulnerable road user secondary safety system warning indicator status, and advanced driver distraction warning time since warning issued, with modified recording intervals, sample rates, and ranges for existing data elements.

Minutes of the 48th SG-EDR conference call meeting held 15-16 September 2026. The group conducted final review of official documents for UN R160 and UN R169, reaching agreement on multiple technical specifications: DDAW recording duration of 60 minutes (bracketed for GRSG consideration), DCAS duration of 1000 seconds and 10 warnings, LDWS and data element frequencies of 4 Hz and 10 Hz respectively, yaw rate frequency increased to 10 Hz, and airbag warning lamp adjustments. Transitional provisions set for 2030 and 2035. EDR Step 3 workstream planning identified topics including triggering sensitivity, data elements, L-category vehicles, and data survivability. Governance discussion noted DSSAD separation under IWG ADS2, with EDR work continuing under potential new taskforce structure.

Proposal to amend para. 1.4. to clarify requirements for recording data elements when sensors or systems are not operational or cannot meet specified format requirements, amend para. 2.20. to redefine engine throttle as driver-requested acceleration torque demand, amend para. 2.73. to define trigger activated, amend para. 5.4.3. to clarify crash test data element requirements and specify impact severity levels by reference to UN Regulations Nos. 94, 95, and 137, insert new paras. 12.12.–12.17. containing transitional provisions with applicability dates from entry into force through 1 September 2035, and amend Table 1 in Annex 4 to modify data element recording intervals, sample rates, ranges, accuracy, and resolution specifications, add new data elements including vulnerable road user secondary safety system warning indicator status, corrective steering function status, emergency steering function status, automatically commanded steering function category status, accident emergency call system status, advanced driver distraction warning, driver control assistance system driver monitoring system warning data, driver drowsiness and attention warning, and time to collision, and clarify footnote references.

The document describes automated shuttles as vehicles designed for public transport with autonomy by design, typically with fewer than 10 seats, constructed like Class A buses, and often limited in maximum speed or bidirectional. Automated shuttles are deployed globally and already comply with most technical requirements for M₂/M₃ vehicles except some UN R107 requirements and bidirectional aspects. Current UN vehicle categories are incompatible with shuttles: M₁ does not have provisions for standing passengers, and shuttles cannot be granted approvals to most UN Regulations because they have fewer than 10 seats. Three options for categorization are presented: a new category M₄, a new class of M₂/M₃ (Class C), or redefinition of M₂/M₃ Class A. A workshop is proposed for 4 December in Paris to determine whether an international category or class is necessary.

Final draft proposal to amend para. 1.4. to clarify that recording requirements depend on availability of the trigger or data element itself, amend para. 5.3.1.2. to permit the EDR to write last stop trigger data in volatile memory only, accommodating at least five most recent stops to be overwritten on a first-in first-out basis until any other trigger occurs or the vehicle master control switch is deactivated, and amend paras. 2.5., 2.48. and 2.49. for clarity and consistency with UN Regulation No. 160.

Proposal to amend para. 1.4. to clarify that recording requirements depend on availability of the trigger or data element itself rather than sensor format capabilities, amend para. 5.3.1.2. to permit the EDR to write Last Stop trigger data in volatile memory only, accommodating at least five most recent stops to be overwritten on a first-in first-out basis until another trigger occurs or the vehicle master control switch is deactivated, and amend paras. 2.5., 2.48. and 2.49. for clarity and consistency with UN R160.

Proposal to introduce provisions for type approval of Moving Off Information System (MOIS) Component and Separate Technical Unit (STU) by establishing three approval pathways: Part I for vehicles with MOIS, Part II for vehicles with installation of approved MOIS Component or STU, and Part III for MOIS Component or STU themselves. The system detects pedestrians and cyclists in the forward blind spot area and provides information and collision warning signals during low-speed moving off manoeuvres at speeds of 10 km/h or less. Technical requirements cover detection performance for speeds 3–5 km/h for potential moving off and 0–10 km/h for low-speed operation, automatic deactivation on system failure or sensor contamination, manual deactivation through intentional driver actions, and signals that are deactivated together upon failure. Test procedures include static crossing tests, longitudinal stopping and moving off cyclist tests, and failure detection tests performed on flat dry asphalt under natural illumination conditions.

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.

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 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 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 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 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 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 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.
