Request from the GRSG secretariat for clarification of a possible inconsistency in the text of UN R144. Paragraph 26.7.2. refers to situations where the AECS is not equipped with a back-up power supply; however, the subparagraph 26.7.2.3. refers to an AECS with a back-up power supply.

Presentation from the caravan and recreation vehicle industries of Australia, Canada, Japan, Korea, and the United States proposing to develop a reference in collaboration with GRSG on their vehicle construction and use.

Proposal to clarify that UN R144 does not specify the frequency (number) of attempts or the duration of efforts to establish a network connection (voice or data transmission) for automatic emergency call systems.

Proposal to update the definition of “key” in line with technological progress and clarifying that a “key” is specifically a means for access, not an anti-theft system.

Proposal to require measure(s) to prevent a bus or coach from moving while a lift or ramp is not in its stowed position.

Proposal to clarify that the term “special joint” does not include flexible components supporting coupling articulation (as is pertinent to Class C50 couplings).

Presentation on new national legislation that defines a new vehicle category, “urban shuttle”. The legislation skirts the current M category definitions by defining an urban shuttle as having a total capacity to carry between nine and 16 passengers plus a driver with seating for 4-5 passengers. As such, France intends to propose national type approvals for such vehicles with a view to address driverless versions in future legislation.

Presentation on the status of the informal working group on bus management of fire events (BMFE).

Proposal to add a line for restrictions on the use of Class T couplings to the type-approval communication form.

“Arrêté du 6 mai 2019 définissant les conditions d’homologation, d’exploitation et de circulation des navettes urbaines”

Status report including a proposal to update UN R116 electromagnetic compatibility annexes.

Proposal to align UN Regulation No. 67 with ISO 19825 by changing the name of the light vehicle Euro filling unit to K15 and inserting a new profile J15 into Annex 9.

Proposal to allow for the approval of optical reflecting mirrors being introduced to the market in addition to the current spherical product.

Updated proposal to clarify provisions for periodic testing and periodic requalification of Compressed Natural Gas (CNG) cylinders and Liquefied Natural Gas (LNG) tanks.

Presentation on technologies to provide driver with augmented view of roadway (e.g., visual overlays projected against windscreen) and restrictions under UN R125.

Proposal to add the condition " and any part of the vehicle which is more than 2.0 m above the ground" to the definition of the “vehicle front right corner” to ensure that the BSIS detection zone is not adversely affected by specific elements added at later stages of completion of the vehicle (e.g., a crane).

OICA comments on the NGV proposal (document GRSG/2019/28) to introduce changes/additions in the Change of Design Table to better specify appropriate test requirements for CNG cylinders with composite materials and, in some cases, to harmonize with International Standard Organisation (ISO) standard 11439.

Proposal to clarify the regulation with regard to cone placement in the test procedure.

Presentation in support of the proposal in document GRSG-117-16.

Revised text with transitional provisions for the proposal (GRSG/2019/6) to specify that "the motor-vehicle’s user instructions (e.g. owner’s manual, vehicle handbook) shall clearly specify that the removable or repositionable mechanical coupling device shall always be removed or repositioned when it is not in use.” The purpose is to comply with an EU General Safety Regulation provision that prohibits couplings from obscuring rear lighting components or registration plates.

OICA comments on the original proposal (GRSG/2019/11) regarding interpretation of “contactable parts” and wiper systems. GRSG/2019/11 has been superseded by a revised proposal (GRSG/2019/34) incorporating the OICA comments.

Proposal to add new definitions, modify the description for Category L vehicles to align with addition of 4-wheel quadricycles, and update references to external standards.

Full UN R144 integrating the proposal to:

1. clarify that the application of an AECD approval to other vehicle categories than M₁ and N₁ is not mandatory,
2. align the power supply requirement of Part III, para. 34.1 with the corresponding requirement in Part II, para. 25.1.
3. clarify with regard to para. 34.1 that if the vehicle is equipped with both
   • -a “back-power supply” as listed in para. 35.10.1 and
   • -a “Power supply other than back-up power supply mentioned in paragraph 35.10.1” as listed in para. 35.10.2
   both should be tested according to Annex 9. The “Power supply other than back-up power supply mentioned in paragraph 35.10.1” should indeed only be tested if it is the only power supply for the AECS.
4. include two-year transitional provisions
5. remove the exclusion of M₁ and N₁ not equipped with a side airbag and to specify that the AECS shall be able to output the navigation solution in an NMEA-0183 protocol format (RMC, GGA, VTG, GSA and GSV message), among other clarifications.

Revisions to the proposal to update Part III of UN R93 to enable approval of truck cabs where the front underrun protection is integrated in the motor vehicle (in order to improve aerodynamic performance). The proposal includes transitional provisions from 1 November 2025.

Revised proposal to allow an alternative positioning and spacing of escape hatches on buses of Classes A and B to address limitations for shorter vehicles.

Updated proposal to exempt Zone I from opaque obscuration requirements of GTR 6 under certain conditions.

Proposal to add a missing footnote and to clarify the application of Annex 4 for heat pumps.

Changes to the proposal to exempt rear edges of fenders and rear edges of A pillars under certain conditions.

Proposal to modify the draft Amendment 2 to GTR 6 regarding obscuration area definitions.

Request from the originator of the proposal (regarding the measurement of distances of the left-most foot control from the cabin “wall”) to remove it from the session agenda.

Proposal to modify the scope and transitional provisions of the proposal concerning aerodynamic cabs.

Proposal for a mutual resolution [No. 4] concerning recommendations on ceramic printed area widths for panoramic sunroof designs.

Proposal to correct a typo: “Class II to IV VI exterior device”

Proposal to align requirements for conventional mirrors and camera-monitor systems. In the latest revision (where mirror and CMS provisions were split into separate sections), the phrase “including those parts remaining attached to the
support after the test provided for in paragraph 6.3.2. below” was omitted from the CMS section.
