Proposal to correct the wording in UN R43 (Safety Glazing). The expert from the European Association of Automotive Suppliers proposes amending paragraph 8.2.1.1. to modify a table listing tests for windscreens and glass panes of various types, including toughened glass, ordinary laminated glass, treated laminated glass, and glass-plastics. The amendment corrects the title of the optical distortion test listed in the table.

Status report on the Special Interest Group on Component & Separate Technical Unit work on UN R158 and UN R159. The SIG-C&STU is developing proposals to add Component and Separate Technical Unit approval routes to UN R151, UN R158, UN R159, and UN R166. For UN R159, Supplement 4 is under review with documents at GRSG-132. For UN R158, a Proposal for Supplement 7 is in development. The group requests feedback on structural approaches and timelines for working document submissions by January 2027.

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 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 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 amend para. 8.2.1.1. to replace “Optional distortion” with “Optical distortion” in the table of tests for windscreens and glass panes. The amendment corrects the title of the optical distortion test listed in the table.

Proposal to amend UN R159:

• Insert new title establishing a three-part regulatory structure for Moving Off Information Systems approvals,
• amend and renumber paragraphs throughout to reorganize content into Part I (vehicles regarding MOIS), Part II (vehicles regarding MOIS installation of approved Component or Separate Technical Unit), and Part III (MOIS Component or Separate Technical Unit),
• insert new paragraphs defining approval types and vehicle/component/STU classifications,
• amend definitions to clarify MOIS Component and Separate Technical Unit,
• establish permitted variations and representative test setup requirements,

• insert new Annexes 2–7 providing communication and information documents for vehicle and component/STU approvals,
• renumber existing Annexes to 8 and 9,
• introduce approval mark provisions for components and STUs.

This document presents VDA 812-001 (05/2026), a recommendation for qualification of pyrotechnics and inflators for automotive restraint applications. The recommendation combines a Propellant Information Package and inflator ageing procedures. Propellant must demonstrate robustness against thermal stimulus of 107°C for 408h or 90°C for 1000h and moisture stimulus, with mechanical stability, density, and burn rate criteria assessed before and after ageing cycles. Inflator evaluation addresses structural safety, functional safety, effluents, performance characterization, and environmental simulation, including high temperature oven testing, accelerated heat ageing, and sequential environmental testing to ensure suitability for restraint systems.

Proposal to amend UN Regulation No. 129 to remove rebound head contact from the head acceleration requirement for all Child Restraint Systems. The regulation currently lacks consistency regarding whether rebound head movement is considered in testing. Variations in test bench design cause booster seats to pass in some laboratories but fail in others based solely on rebound contact. The proposal ensures consistency between different CRS types and reproducibility across laboratories with different test bench designs, and aligns with the approach in UN Regulations 94 and 137.

Proposal to replace the reference to EN 71-3:2019+A1:2021 with EN 71-3:2019+A2:2024 in para. 6.3.1.1. and replace the reference to EN 71-2:2020 with EN 71-2:2020+A1:2025 in para. 6.3.1.2. The versions currently referenced have been withdrawn by the European Committee for Standardization, and updating the references to the latest published versions will avoid administrative burdens during the type-approval process of enhanced child restraint systems.

Proposal to replace the reference to EN 71-3:2019 with EN 71-3:2019+A2:2024 in para. 7.3.1.1. The current version of the European Standard for toxicity has been withdrawn by CEN and replaced with a new version. This update reflects the latest published version of the standard to avoid administrative burdens during type-approval of built-in child restraint systems for vehicles of M₂ and M₃.

Proposal to:

• Add clarification to para. 5.3.5. that compliance with maximum head deceleration is not required,
• Add new requirements to para. 5.9.1. limiting head deceleration compliance to parts qualifying as points of head contact,
• Replace ‘point of contact’ with ‘point of head contact’ throughout Annex 1 paras. 2.2., 2.3., 2.3.1. and 3.,
• Insert new para. 1.4.4. in Annex 4 specifying test procedures for contactable points not qualifying as points of head contact,
• Amend Annex 4 para. 2.1. to reference specific procedures,
• Replace ‘point of contact’ with ‘point of head contact’ in Annex 10 explanatory notes to Annex 1 para. 2.2.

Proposal to clarify that the parking brake may be actuated while the vehicle is in motion via actuation of the vehicle’s service braking system by means of an auxiliary control which could be an Electronic Parking Brake (EPB) and to promote consistent interpretation of the activation conditions for an Emergency Stop Signal (ESS), including by application of the service braking system via the EPB control.

The e-Trailer Industry Group reports on discussions regarding electrically propelled and recuperating trailers. ISO 11992-2 Edition 4 is not safely implementable due to incompatibility with current UN regulations, missing PGNs, and risks of malfunction. ISO/TC 22/SC 31/WG 4 launched Edition 5, targeting publication in early 2027. Amendments to UN R13 and UN R100 are being developed in phases, with Phase 1 addressing trailer dynamo function and Phase 2 addressing e-axle trailers. Two workshops with Contracting Parties are planned to establish shared understanding and develop concrete parameter extensions for amending UN Regulations.

Proposal to insert new sub-paragraph 5.6.1.1.4.1 establishing that requirements of paragraph 5.6.1.1.4 shall not apply to ACSF Category A functions provided they are intended solely to support low-speed vehicle controllability manoeuvres in off-road environments, operate only until 5km/h with 1km/h tolerance, require deliberate driver activation, require driver presence in driver’s seat with fastened safety belt, and allow driver to retain control and override or deactivate the system at any time.

Proposal to amend para. 2.8 of Annex 8 to add subparagraph (c). The amendment addresses trailers utilizing service braking system energy reserves for automatic brake requirements. Current para. 2.8 includes options (a) and (b) requiring spring brake pressure reduction or corresponding pressure reduction in spring compression chamber. New subparagraph (c) permits alternative designs where combined service braking and parking braking system activation holds a laden trailer on 18 percent gradients at any service brake energy reservoir pressure from 850 kPa to 0 kPa, providing greater realization flexibility while maintaining required holding performance.

Proposal to amend para. 2.8 of Annex 8 to UN R13 to require trailers utilizing service braking system energy reserves to fulfil one of three requirements when uncoupled and park brake control released: pressure in spring brake compression chamber shall reduce to 0 kPa when energy reserves reduce to 280 kPa, pressure reduction in service braking system energy reserve results in corresponding reduction in spring compression chamber pressure, or combined service and parking braking forces shall hold laden trailer as required when service brake energy reservoir reduces from 850 kPa to 0 kPa.

Proposal to amend para. 5.6.1.2.7. to increase the maximum RCP operating range from 6 m to 15 m. UN R79 currently limits the maximum RCP operating range to 6 m, resulting in effective usable range of 2 or 3 m due to radio wave-based ranging inaccuracy. A 15-meter range would enhance RCP function usefulness and safety, reducing driver movement and blind areas. RCP systems with extended ranges have been used in large markets without identified safety threats. The amendment is proposed as a supplement to the 03 and 04 series of amendments to UN R79.

Proposal to insert new para. 3.1.1. and 3.1.2. requiring manufacturers to provide information to approval authorities prior to application and upon extension of type approval; insert new para. 3.2.2. requiring manufacturers to provide summaries of safety definitions, driver safety levels, traffic rules assessment, and testing for each territory where ALKS can be active; and insert new paras. 4.6. to 4.6.6. establishing procedures for approvals covering multiple territories, including notification of receiving approval authorities at least 30 days before approval, review periods, and dispute resolution under the 1958 Agreement. OICA and CLEPA do not support mandatory pre-announcement but would support sharing Safe Operation documentation and lists of compliant territories during the approval process.

Supporting presentation on the proposal to insert a new sub-paragraph 5.6.1.1.4.1 to exempt ACSF Category A functions intended solely to support low-speed vehicle controllability manoeuvres in off-road environments from the obstacle detection requirements of paragraph 5.6.1.1.4, provided the function operates only until 5 km/h with 1 km/h tolerance, is activated deliberately by the driver in off-road environments only, requires the driver to be in the driver’s seat with safety belt fastened, and allows the driver to retain control and override or deactivate the system at any time.

OICA-CLEPA-EME comments on German proposal GRVA-25-07 to require the approval authority granting UN R155 or UN R156 type approvals to use CSMS or SUMS certificates signed by the same approval authority. OICA-CLEPA-EME identify that CSMS and SUMS are Management Systems covering entire manufacturer organizations, and mandating the same approval authority for Management Systems certificates and approvals will have significant consequences for original equipment manufacturers typically using multiple approval authorities in homologation. The submission proposes keeping text unchanged to allow different approval authorities for Management Systems certificates and type approval based on voluntary acceptance, implementing wording on information exchange if different approval authorities are involved, and establishing a horizontal approach for Management Systems with mutual recognition aspects considered.

Proposal to delete paragraph 1.2.6. excluding e-axle trailers with e-axles providing electric propulsion and/or incorporating an electric regenerative braking system from the scope of UN R13, and add definitions of “e-axle,” “e-axle trailer,” “dynamo function,” and “e-trailer”; add special requirements for power-driven vehicles supporting e-trailer operation, e-axle trailers equipped with dynamo function, and e-trailers of category O; add requirements for electric control lines conforming to ISO 11992-2:²⁰²⁷; specify message support and functional compatibility; and add provisions for electric regenerative braking, dynamo function, and propulsion, including parameters such as retarder torque demand priority, propulsion force limits, overriding mode activation at speeds below 15km/h, and vehicle stability function interaction.

Proposal to modify the specified maximum remote controlled parking operating range from 6 m to 15 m. Large markets including Canada, USA, and China do not regulate maximum remote controlled parking operating range. Remote controlled parking systems exceeding 6 m operating range are already offered in the field. Radio wave-based ranging is inherently inaccurate due to complicated and varying electromagnetic environment in garage and changing orientation of remote device, requiring safety margin integration into product design, which reduces effective usable range below 6 m maximum. Extended range remote controlled parking systems have been used in the field for several years without negative feedback or identified safety threats.

Document explains concerns about the approach in GRVA/2026/30 to require a single Approval Authority to issue certificates of compliance for Cyber Security Management Systems and Automated Driving Systems Management Systems and vehicle type approval. The proposed changes would lead to double or triple approvals of management systems, creating administrative burden and unresolved legal consequences regarding challenged certificates of compliance and their effects on other issued certificates for the same management system. The submission proposes clarifying existing wording, documenting implications of challenged certificates, and adding a new paragraph 5.1.5. to UN R155 permitting mutual agreement between Approval Authorities regarding certificate usage.

Proposal to amend Article 2, paragraph 2 to clarify that where a Certificate of Compliance required under a UN Regulation and issued by an Approval Authority of another Contracting Party is accepted by a Contracting Party, the Approval Authority granting the corresponding type approval shall remain responsible for all aspects of that type approval. The amendment addresses management systems and their Certificates of Compliance used in UN Regulations such as UN R155 and UN R156.

Proposal to insert a new para. 5.1.12. requiring that whenever an assessment of compliance to a requirement of this regulation is unachievable without reading internal signal(s) of an electronic system, the vehicle manufacturer shall provide instructions and tools to read signals on in-vehicle networks for the technical service to extract and interpret the signal(s), with this information appended to the test report.

Proposal to amend para. 3.4.1. and para. 3.4.4. in Annex 8 to require manufacturers to address how the braking system strategy will not prejudice safe operation due to failures with other systems involved in achieving the function of the system, and insert new para. 4.5. in Annex 6 to require consideration of the effect of implausible wheel-speed information on anti-lock system operation in fault analysis. The proposal responds to a United Kingdom collision involving tyre failure and ABS activation that resulted in unsafe operation.

Status report on e-axle trailer development within GRVA, covering taxonomy, regulatory approach, and progress. The document presents use cases for electric axles in trailers of categories O2, O3, and O4, comparing simplified frameworks for O2 with fully integrated heavy vehicle frameworks for O3/O4. Progress includes updated taxonomy, ISO 11992 standardization work, and completed workshops. Step 2 adoption is targeted for January 2027, with Step 3 planning for O2 trailers to be clarified.

Proposal to amend para. 5.6.1.2.7. to extend the maximum remote control parking (RCP) operating range to a maximum of 15 m if, prior to the operation, a visual message informing the operator of their responsibility is presented to and acknowledged by the operator. The justification notes that RCP systems with ranges exceeding 6 m are already offered in large markets such as Canada and the United States of America, and that such extended-range systems have been used in the field for several years without negative feedback or identified safety threats.

Proposal to insert a new sub-paragraph 5.6.1.1.4.1 to exempt ACSF Category A functions from the requirements of paragraph 5.6.1.1.4, provided that the functions are intended solely to assist the driver in regaining vehicle motion in limited traction conditions in off-road environments up to 5 km/h (+1 km/h tolerance), are activated following a deliberate action by the driver with the driver in the driver’s seat and safety belt fastened, and allow the driver to override or deactivate the function at any time, with the manufacturer to describe system behaviour when operating conditions are no longer met.

Proposal to clarify the provisions
applicable to the type-approval of Risk Mitigation Functions (RMF): Amend para. 5.1.6.3.4. to clarify that the signal to activate hazard warning lights is generated with the start of the intervention and is deemed to start the intervention, amend Annex 8 para. 3.6.1. to specify that hazard warning lights are activated at the earliest five seconds after the warning signal, and amend Annex 8 para. 3.6.2. (Scenarios A and B) to specify the same timing requirement for hazard warning lights activation in tests for RMF bringing the vehicle to a safe stop outside its own lane of travel. The proposal clarifies that the starting time of RMF operation comes with the driver warning and that five seconds should be measured until the hazard warning lights come.

Proposal to amend Annex 8, paragraph 2.8. to establish performance-based requirements ensuring continuous trailer immobilisation during service brake pressure depletion. The amendment requires that when a trailer is uncoupled and the park brake control is released, braking forces from combined service and parking braking systems shall hold the laden trailer at any time when service brake energy reservoir reduces from 850 kPa to 0 kPa, and that adequate overlap between service brake and spring brake functions be ensured so no loss of holding capability occurs during pressure depletion.

Proposal to amend GRVA/2026/34 proposing to amend para. 5.6.1.2.7. to modify the specified maximum RCP operating range from 6 m to 10 m, with provision to extend to a maximum of 15 m if direct line of sight between the remote-control device and the vehicle is ensured. The justification notes that RCP systems with extended ranges are already offered in large markets without regulatory limits, that radio wave-based ranging requires safety margins reducing effective usable range, and that increased range would reduce blind areas behind vehicles and allow drivers to better monitor surroundings while manoeuvring, reducing risks and increasing overall safety.

Proposal to insert para. 3.2.2. requiring manufacturers of Automated Lane Keeping Systems active in multiple Contracting Party territories to provide information on traffic rules identification, territory-specific testing, and contact details, insert paras. 4.8. to 4.8.6. establishing procedures for granting approval authorities to inform and consult receiving approval authorities at least 30 days before approval, allow receiving authorities 30 days to comment on regulation interpretation, require dispute resolution under Article 10 and Schedule 6 of the 1958 Agreement, and insert footnote [Y] stating these provisions shall be kept under periodic review by GRVA for amendment as necessary.

Proposal to insert a new sub-paragraph 5.6.1.1.4.1 to establish exemptions for Automatically Commanded Steering Function Category A functions designed for off-road low-speed vehicle recovery manoeuvres, and amend para. 5.6.1.2.7 to increase the specified maximum Remote-Control Parking operating range from 6 m to 15 m.

Proposal to amend para. 2.8 of Annex 8 to add a new requirement that braking forces from combined service and parking braking systems shall hold a laden trailer as required in Annex 4 para. 3.2.1 at any time when service brake energy reservoir pressure reduces from 850 kPa to 0 kPa, ensuring continuous trailer immobilisation during service brake pressure depletion while establishing a performance-based requirement rather than prescribing specific technical solutions.

At the 94th session of GRPE, CLEPA proposed a draft UN Regulation for approval of replacement brake parts. A dual pathway approach was proposed with two options depending on data availability: fully available data or minimal set of data with worst-case assumptions. PMP Task Force 3c was established to prepare a UN Regulation for approving replacement brake parts regarding particle emissions. The TF3c will define minimum information required under the simplified approach, assess variability within a family, and identify worst-case assumptions. CLEPA presented two approval concepts and requested support for Option A only. The next meeting is scheduled for 18 May 2026.

• Insert transitional provisions 12.12.–12.16. providing that as from the official date of entry into force Contracting Parties shall not refuse type-approvals under the 03 series, as from 1 September 2031 or 2029 [date TBD] shall not accept type-approvals to preceding series first issued after that date, until 1 September 2033 shall continue accepting preceding series approvals first issued before 1 September 2031 or 2029 [date TBD], may grant approvals to preceding series, and shall grant extensions of existing approvals
• Amend Annex 4 Table 1 to split engine throttle and accelerator pedal data elements, increase sampling rates to 10 Hz, extend recording intervals for rollover events, add pre-event synchronization timer, trigger activated, ACPE status, ADDW status, DDAW status, blind spot monitoring status, turn signal status, DCAS status, DCAS driver monitoring system warnings, emergency stop signal status, and time to collision data elements, and modify footnotes accordingly

Proposal for a recording interval of 600 seconds prior to collision for driver drowsiness and attention warnings (DDAW), 240 seconds for advanced driver distraction warnings (ADDW), 240 seconds prior to collision for driver monitoring warnings from the driver-control assistance system (DCAS), triggers planar, VRU, Rollover, AEBS, AEBS for pedestrian, AEBS for bicycle, and AEBS for motor vehicle, and event data recording time-to-collision (TTC) range of 0 s to 5.0 s and resolution 0.1 s for AEBS events.

For vehicles equipped with an Automated Driving System, it shall be possible to retrieve DSSAD time-stamp data elements specified under paragraph 5.2. of Annex 8 of UN Regulation No. 185 recorded within at least the last 30 seconds prior to triggering of the respective EDR event, regardless of whether the DSSAD and the EDR are implemented as a single system or as separate systems. The time-stamp data elements retrievable from the DSSAD shall include the record for the last activation or deactivation of the feature used at the time of the event within the same power cycle. The data elements shall be retrievable in the format specified in Annex 8 of UN Regulation No. 185, though DSSAD location data may be omitted and dates and times recorded may be replaced with information representing the time elapsed between the recording of each DSSAD data element and the triggering of the EDR.

The document addresses how to define and measure effective seat belt webbing length for buses of category M₂/M₃. It proposes defining effective length by pulling the lap belt at the geometrical midpoint under a 60-degree angle to form an equilateral triangle, where the leg on the buckle side defines 50 percent of pursued effective length for 2-point belts and 25 percent for 3-point belts. Additional webbing for attachment, handling, connection to spool, and spool length must be added based on seat design and geometry. The proposal suggests the definition may work using diagonal belt alone in the ghost position and questions where to include it in UN R173.

UN R145 and UN R173 establish optional ISOFIX installation for vehicles of category M₂ and M₃. ISOFIX seating positions require compatibility with specific Child Restraint Fixture volumes and lower isofix forward strength of 8kN. I-Size seating positions require minimum 440mm distance between adjacent positions, compatibility with ISO/F2X and ISO/R2, and additional support leg strength testing. The document proposes allowing labels on bus windows and removing marking requirements for M₂ and M₃ from UN R145.
