The amendments update footnotes across documents to reference the Consolidated Resolution on the Construction of Vehicles (R.E.3.), document ECE/TRANS/WP.29/78/Rev.8. The document modifies provisions related to Automated Driving Systems and Advanced Driver Assistance Systems sensors, test mass specifications, logical signal transmission, acoustic characteristics, category definitions, and occupant compartment requirements across multiple regulations.

The agenda includes amendments to UN Regulations and GTRs regarding their fitness for automated vehicles, review of documents received for review, compilation of an informal editorial document for the 199th session of WP.29, future steps of the work, review of past open and low-priority items, discussion on future needs for ADS fitness and general regulatory fitness, and agreement on the contents of the final presentation to WP.29.

The document addresses consistency issues across multiple UN Regulations (R26, R28, R29, R34, R35, R39, R43, R45, R46, R48, R49, R134, R135, R137, R138, R141, R142, R143, R144) concerning automated driving systems. It proposes improved wording for fuel leakage provisions, foot control applicability for vehicles of category M₁, and speedometer requirements when ADS features are active. The document recommends removing duplicate definitions of ADS, DDT, bi-directional vehicle, and forward direction across regulations. It raises questions regarding application to category Y vehicles, handling of bi-directional traffic equipped vehicles, and whether requirements should apply to vehicle users or only when ADS features are active.

Proposal to amend ECE/TRANS/WP.29/2026/89, ECE/TRANS/WP.29/2026/90, ECE/TRANS/WP.29/2026/95, ECE/TRANS/WP.29/2026/96, and ECE/TRANS/WP.29/2026/98 to modify para. 2.11.3. to define reference point for bi-directional vehicles, amend para. 2.31. to define bi-directional, amend Annex 3 Table 2 test mass values for vehicles in categories X and Y and vehicles equipped with ADS, amend para. 5.1.6.1. to specify logical and optical signals for category X or Y vehicles with ADS, amend para. 6.2. to reference ADS-specific provisions in Annex 5, amend Annex 9 paras. 2.2., 2.2.1., and 2.2.2. regarding vehicles equipped with ADS other than categories X and Y, amend para. 11.7. to define Category Y vehicles, add new para. 14.1.6. specifying ADS provisions in Annex 7, and amend para. 14.3. regarding pause function design for ADS features.

The agenda includes discussion of the upcoming process for submission of documents and corrections to documents submitted by TF AVRS with track changes and justifications, and consideration of next meetings.

Corrections to documents submitted by TF-AVRS and approved by GRBP amend terminology in UN R51.03 to harmonize bidirectional spelling, correct vehicle category references in UN R51.03 and UN R165 to reference category X only rather than non-existent category M1Y or category M, clarify in UN R64 that logical signals shall be transmitted to the ADS when an ADS feature is active, introduce references to specific ADS provisions in Annexes 5 and 7 of UN R138.02 and UN R165, add grammatical corrections to UN R141, and align UN R165 terminology with ADS regulation language.

Corrections to documents submitted by TF-AVRS and subsequently by GRBP were adopted without additional proposals. The next meeting is to be scheduled at a later date, if needed.

Proposal to amend para. 6.1.5. to state that sensors, cameras, radar devices, etc. being part of driver assist systems and automated driving systems may become damaged, disoriented or broken due to an impact as long as basic braking and steering performance remain intact. The amendment enables application of UN R42 to vehicles equipped with an Automated Driving System.

Proposal to insert a new para. 0 introducing supplements 4 and 5 to the 04 series of amendments extending the Regulation to vehicles of categories X and Y, amend para. 1 to modify scope provisions and add R-point clarifications for category X vehicles, amend para. 2.8 to revise the bonnet rear reference line definition including provisions for category Y vehicles without windscreens, amend para. 2.22 to clarify front structure definition for categories X and Y, amend para. 2.29 to specify occupant mass placement for categories X and Y, amend para. 2.32 to define side reference line for category Y vehicles, amend para. 2.44 to redefine windscreen test area for category Y vehicles, and amend para. 2.45 to adjust cowl monitoring area for category Y vehicles.

TF-AVRS submitted its status report to GRSP-79, advancing work on draft new Y-category Passive Safety Regulation and amendments to UN R127 for Y-category vehicles. The draft regulation addresses fuel system integrity, electrical shock protection, and crash compatibility based on UN R94, R95, R137, and R153. Horizontal items included eliminating R point problems, passenger compartment references, and A and B pillar designations, with harmonised mass definitions and consolidated numbering. Targets for 2026 included reviewing AVRS-adopted documents, correcting three regulations, and consistency checks across ADS amendments for WP.29-199.

TF-AVRS submitted a draft new Y-category Passive Safety Regulation to GRSP-79 in June 2026. The regulation addresses fuel system integrity, electrical shock protection, and crash compatibility for frontal, rear-end, and lateral collisions. The Task Force eliminated the R point problem, passenger compartment references, and A and B pillar designations, harmonised mass definitions, and consolidated numbering and cross-references. Open items include determining additional requirements, specific vehicle measurements, and finalising Annex elements. Subsequent informal documents are planned for GRSP-79, with working documents for GRSP-80.

The 25th session of the GRSP Task Force on Automated Vehicles Regulatory Screening (AVRS) was held online on 28 April 2026. The Task Force discussed regulatory frameworks for Y-category vehicles, including mass compatibility and crash test exceptions, and reviewed UN Regulation 127 on pedestrian protection for Y-category vehicles. The Task Force also addressed UN Regulation 12 feedback and identified minor mistakes in three proposals: ECE/TRANS/WP.29/2026/63, ECE/TRANS/WP.29/2026/65, and ECE/TRANS/WP.29/2026/71, which require corrections before submission to WP.29.

The 22nd session of the Task Force on Automated Vehicle Regulation Screening is scheduled for 20 May 2026 from 09:00 to 11:00 (CET) as an online meeting. The agenda includes welcome and opening remarks, adoption of the agenda and report of the 21st session, feedback and remarks from WP.29 expert groups on regulatory fitness for automated driving systems, determination of next meeting(s), and adjournment.

UN R127 amendment proposals include defining pedestrian protection requirements for category Y vehicles. Scope exemptions for category Y vehicles shall use front structural geometry to determine exemptions, ensuring equivalence to R-point criteria. Definitions require adjustments including Bonnet Rear Reference Line for vehicles without windscreens, Front structure definition to include automated driving sensors, Windscreen test area redefined as Upper structure test area where windscreens are non-existent, and supporting definitions for Side reference line and Cowl monitoring area. Testing shall occur at Unladen Vehicle Mass.
