| UN R10: Proposal for a revised Supplement to the 07 series of amendments |
| Reference Number: GRE/2026/16/Rev.1 |
|
Proposal to amend UN R10 by inserting new paragraphs to address Automated Driving System (ADS) requirements. The supplement to the 07 series of amendments extends the Regulation’s application to vehicles of categories X and Y equipped with an ADS, as well as conventional vehicles with an ADS, while maintaining the spirit of the original Regulation. Modifications include new definitions for “ADS test configuration,” revised immunity related functions to account for ADS sensor performance, and updated test conditions specifying that ADS shall be operational during testing. Alternative testing methods may be used when the ADS cannot function in the laboratory environment, subject to type-approval authority agreement. |

| Children Left in Vehicles: Summary of the 15th (March 2026) session |
| Reference Number: CLIV-15-08 |
|
The CLIV informal group held its 15th session in Seoul from 24–27 March 2026, focusing on drafting performance requirements for buses and coaches. Japan proposed a five-minute inspection duration for drivers to confirm all children have disembarked; however, OICA suggested linking inspection time to passenger capacity. On Day 3, Japan presented a revised position: buses with 25 or more passenger seats require five minutes before a CLIV warning event occurs, while buses with fewer than 25 passenger seats require three minutes. All delegates supported this approach. The IWG agreed to draft papers for submission to affected GRs concerning external audible and visual warning signal proposals and intends to submit the draft UN Regulation to GRSP for informal consideration at the June 2026 GRSP session. |

| Comments for Emergency Door Opening discussions |
| Reference Number: EDO-05-08 |
|
Comments address proposals EDO-05-03e and EDO-05-04e. On intuitiveness, the definition was agreed upon but concerns remain regarding ambiguity under self-certification system. Specific examples may be included such as door handle with gripping space, and mark/label/symbol on latch control. On power loss test, overall test procedures were agreed upon. Clarifications needed include normal riding position in 2.2.3., and whether interior test testers proceed with opening procedure after 60 minutes for all doors with 4 times repetition per door within 60 minutes proposed. |

| Vehicle sound limits: Cross Matrix Activity-A brief history |
| Reference Number: TFVS-20-02 |
|
The Cross Matrix activity began with TFSL-02-07 (May 2021) defining the concept to assess regulation effects across different areas. TFVS-04-14 (Sep. 2021) clarified building a sound model. Early work 2021-2022 defined traffic and fleet scenarios through TFVS-05-06, TFVS-06-03, TFVS-07-08, and TFVS-06-05, which selected eight scenarios from residential areas to motorways. Activity decreased by 2023, with TFVS-12-06 calling for resumption. TFVS-17-07 compared model results from EU, Switzerland, Japan, and HMG Akustiklabor. Future steps include addressing Lmax, traffic measure effects, opening the approach to L categories, and assessing progress from new RD-ASEP in UN R41 06 series. |

| Direction Indicator Lamp Height Issue |
| Reference Number: SLR-77-13 |
|
This document addresses rear direction-indicator lamps mounted at low positions on vehicles. Republic of Korea reports increased public petitions and media articles regarding visibility and recognition concerns, particularly in congested traffic and for vehicles with higher driver seating positions like SUVs. UN Regulation No. 48 specifies direction-indicator lamp height requirements: not less than 350 mm and not more than 1,500 mm, or up to 2,100 mm under certain structural conditions. The presentation seeks feedback on similar issues from other countries and manufacturers. |
