Proposal to exempt ADS vehicles of subcategories X and Y from requirements related to the presence of a human driver and manual driving controls. The proposal permits X and Y vehicles to use alternative materials for windscreens given their 6 kph speed restriction. The proposal further permits translucence levels below 70% for ADS vehicles while an ADS feature is active (i.e., performing the DDT).

Proposal to require driver signals to be transmitted to the ADS and to introduce provisions for assessing ADS responses to the signals.

Proposal to enable the application to ADS vehicles, including exemptions of vehicles of subcategories X and/or Y from certain provisions concerning manual driving, attention to non-DDT tasks otherwise performed by the driver, introduction of provisions for “ADS features of type 1 and type 2”, and to update provisions concerning the running mass and occupants.

Proposal to enable application of UN R116 to ADS vehicles.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R121 to ADS vehicles, including the exemption of vehicles of subcategory Y from the requirements of the Regulation.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable the application of UN R122 to ADS vehicles and to ensure that the requirements minimise the risk of burns across all vehicle occupants.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R125 to ADS vehicles, including the exemption of vehicles of subcategories X and Y.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to exempt ADS vehicles of subcategory Y from the requirements and to adapt the requirements for application to ADS vehicles, including vehicles of subcategory X. The proposal relies on the establishment of requirements for ADS vehicles to define specifications for ADS performance while an ADS feature is active.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R151 to ADS vehicles, including the exemption of vehicle subcategories X and Y from the requirements, and to remove the references to Unique Identifier markings.

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.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to exempt vehicles not operated by a human driver from the requirements of this Regulation, including vehicles of subcategories X and Y, and to delete the provisions concerning Unique Identifier markings.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable the application of UN R161 to ADS vehicles.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R162 to ADS vehicles.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R163 to ADS vehicles.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R166 to ADS vehicles, including the exemption of ADS vehicles of subcategories X and Y from the requirements of the Regulation.

Proposal to exempt vehicles of subcategories X and Y (ADS vehicles) from the requirements on UN R167 and to delete the provisions for Unique Identifier markings.

Proposal from the GRSG task force on Automated Vehicles Regulatory Screening to exempt ADS vehicles of subcategories X and Y from the requirements of UN R176.

Proposal to clarify that ocular reference point adjustment applies only to back angle, and to reference the original version of UN R166 to prevent future ambiguity should Annex and paragraph numbering change in subsequent amendments.

Proposal to clarify that transparency requirements under UN R43 apply in both directions (exterior to interior and interior to exterior), addressing the growing use of privacy foils on windscreens and front side windows post-registration, which raises safety concerns regarding driver eye-contact, law enforcement visibility, and driving behaviour enforcement, consistent with the position expressed by GRSG at its 130th session.

Proposal to remove subjectivity and clarify manufacturer requirements for demonstrating equally effective triggering performance in vehicles with a maximum mass between 8,000 and 12,000 kg.

Proposal to align UN R43 with a proposed amendment to UN R125 (ECE/TRANS/WP.29/GRSG/2026/23), which resolves a longstanding inconsistency between the lower datum point definition (§5.1.1.3) and the obstruction requirement (§5.1.3) by harmonizing the lower datum point angle from 5° to 4°.

Proposal to resolve a longstanding inconsistency in UN R125 between the lower datum point (§5.1.1.3, set at 5°) and the obstruction requirement (§5.1.3, set at 4°), by aligning the lower datum point to 4° while retaining upper and lateral aspects of §5.1.1. unchanged. The 5° datum point has never been used for any technical requirements beyond serving as a reference point, while the 4° obstruction requirement has prior precedent. As this is a vehicle rather than component requirement, the datum point is also proposed for deletion from UN R43, retaining it solely in UN R125.

Proposal to amend UN R167 to address Automated Driving Systems (ADS), exempting category Y vehicles and category X vehicles without a manual on-board mode from the regulation’s scope, while requiring ADS-equipped vehicles to comply when operated manually. Additional amendments update references to the three-dimensional H-point machine per Mutual Resolution No. 1, and revise approval marking provisions to remove the Unique Identifier option.

Proposal to align requirements across different series of amendments to UN R46, and to harmonize requirements for components inside and outside the vehicle with those of UN R26 and UN R61. For detailed explanations, see the TF UN-R46 report (GRSG-130-32) distributed at the 130th GRSG session.

1. The allowed obstruction for devices of Class II, III and VIII,
2. The definition of the external original surface and the position of the cylinder,
3. The usage of indicators and overlays in the required field of vision
4. Protruding supports and their possible interference with the pendulum, and
5. Make corrections to figures.

The initial regulations for Driver Drowsiness and Attention Warning and Advanced Driver Distraction Warning systems were adopted at GRSG-130 and WP.29-198. DDADWS is developing 01 series regulations, with workshops and online meetings planned. The group seeks a mandate extension to October 2028 to complete 01 series development, with proposed submission for approval to GRSG-136.

Proposal to extend the mandate of the DDADWS informal group until October 2028 to enable development of new (01) series of amendments to the original texts of the driver drowsiness and driver distraction warning systems regulations.

Proposal to correct cross-references in UN R73. The amendments modify paragraphs 12.1, 15.1, and Annex 3, paragraph 2.4 to replace incorrect paragraph citations with accurate ones. The corrections address invalid references that do not exist or lack contextual relevance. The changes do not increase requirement stringency.

Proposal to correct cross-references in UN R73. The document amends paragraphs 12.1, 15.1, and Annex 3 paragraph 2.4 to correct invalid or non-existent paragraph references. Changes include updating references from paragraphs 12.4.4 and 15.2.4 to 12.4.2/3 and 15.2.2/3 respectively, and replacing the non-existent paragraph 2.8 reference with paragraph 12.10. The corrections do not increase requirement stringency.

Proposal to introduce provisions for rollover protection systems, advanced emergency braking systems, vulnerable road user secondary safety systems, and driver assistance systems. Amendments clarify triggering conditions for event recording and data locking, expand data elements to capture vulnerable road user collisions and advanced safety system interventions, increase sample rates for improved data granularity, and add transitional provisions for type-approval acceptance timelines.

Proposal to amend UN R169 by inserting definitions for non-volatile and volatile memory, and modifying the Last Stop trigger criteria. The amendment allows threshold criterion (a) data to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates. This reduces memory wear in vehicles with frequent stops exceeding 20 seconds.

CLIV is developing a new UN Regulation for vehicle categories M1, M2, M3, and N1 in Phase 2. The draft regulation requires visual and audible external warnings upon detection of a child left in a vehicle. Visual warnings use direction indicator lamps flashing in SOS morse code pattern for at least 15 seconds, then off for no more than 30 seconds, repeating for at least 10 minutes. Audible warnings must exceed 60dB(A) following the same timing pattern. The IWG requests guidance on potential amendments to UN R48, UN R28, and UN R165.

Five documents propose amendments to UN R46 series 02-07 to align requirements with UN R26 and UN R61, particularly regarding soft parts of camera monitoring systems and mirrors based on Shore A hardness. The 05 series introduced alignment requirements; harmonization is proposed for earlier series with existing approvals.

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 document highlights WP.29 sessions from November 2025 and March 2026. Topics include mirror foils on vehicles requiring multi-working party coordination, categorization difficulties for three-wheeled dump trucks under R.E.3, and promotion of global representation in officer elections for WP.29 and subsidiary groups. The Vulnerable Road Users Informal Working Group was dissolved. GRSG may adjust priorities following a workshop on Door Opening Warning Systems. AC.3 discussed revising interim election agreements to broaden participation beyond original principal negotiators.

Proposal to amend GRSG/2026/30. This document proposes amendments to UN Regulation No. 46 to clarify definitions and requirements for devices for indirect vision. The amendments include revised definitions of external original surface, protruding supports, housing, and arm; clarifications to paragraphs 6.1.1.10 and 6.2.1.4 regarding projection limits in folded positions; modifications to paragraph 15.2.4.9.2 concerning obstruction and horizon visibility; and amendments to paragraph 16.1.1.3.1 addressing safety-related rearward indirect vision information.

Proposal to clarify opaque obscuration in indirect vision devices. The proposal inserts a definition of opaque obscuration and amends paragraph 15.1.4 to correct a reference to UN R43, Annex 24 rather than Annex 21. Paragraph 15.2.4.9.1 is amended to exclude areas of opaque obscuration from obstruction calculations for Class I rear-view devices, treating them similarly to mandatory rubber sealings used for window mounting.

The IWG on EDR/DSSAD developed draft proposals for Event Data Recorder for conventional and automated/autonomous vehicles and Data Storage System for Automated Driving. Completed work includes UN R160 on light duty vehicle EDR, UN R169 on heavy duty vehicle EDR, and DSSAD requirements. Current activities address EDR Step 2 and DSSAD Phase 2. The IWG resolved assessment subjectiveness for vehicles with maximum mass up to 12t through a proposed Supplement 2 to UN R169.

This proposal is to add Component and Separate Technical Units (STU) approvals regulatory supplement to the UN Regulation No. 159 for “Uniform provisions concerning the approval of motor vehicles with regard to the Moving Off Information System for the Detection of Pedestrians and Cyclist”
.

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 clarifies the test procedure of endurance test for pressure regulators.

This informal document GRSG-131-20 presents an artificial intelligence analysis of energy waste and CO2 generation by poorly insulated or uninsulated cars. The analysis compares cars with good roof insulation (metal roofs with 2-3 cm foam/felt) versus poor or no insulation (glass roofs or thin headliners) across 20,000 km annual driving. For gasoline cars, poor insulation wastes 70 L/year and generates 175 kg additional CO2. For electric vehicles, it wastes 200 kWh/year and generates 100 kg additional CO2. Across a weighted fleet, poor insulation costs $61 annually per car. Globally, approximately 600 million poorly insulated cars waste $36.6 billion annually and generate 91.2 million tons additional CO2 yearly.
