Analysis examined 14 cases in Japan where child fatalities occurred after children were left unattended in passenger vehicles of category M₁ and N₁ between January 1984 and April 2025. Indirect sensing could potentially have generated an alert in 13 cases, while direct sensing could potentially have generated an alert in 5 cases. Based on these findings, retaining indirect sensing as an option for UNR is proposed.

Proposal to renumber paragraph 5.8.4.2. as paragraph 5.8.4.3., insert new paragraph 5.8.4.2. requiring controls of electric side windows adjacent to the front seat row to be within reach and directly accessible, insert new paragraphs 5.8.8. and 5.8.8.1. to 5.8.8.2. requiring electric side windows of the front seat row to function for at least 2 minutes during vehicle submergence, and insert new Annex 11 prescribing submergence test procedures including container-based test, slope-entry test, and alternative test methods to demonstrate window opening capability under water.

Working draft proposal to:

• Amend paragraph 1.1. to include application to evacuation of occupants in emergency event
• Amend the definition of child safety lock system in paragraph 2.7.1. to specify prevention of unlatching when interior latch release control is activated and describe normal locked/unlocked logic when inactive,
• Amend the definition of full locking system in paragraph 2.7.2. to refer to interior latch release control,
• Amend the definition of door closure warning system in paragraph 2.9. to replace ignition with master control switch,
• Insert new paragraphs 2.30. to 2.38. defining latch release control, door handle, retractable door handle, unlock, unlatch, power loss, vehicle master control switch, main power supply, and door opening,
• Insert new paragraph 5.4. establishing requirements for exterior and interior door operation including latch release controls, door handles, and unlocking means,
• Amend paragraphs 6.3.1. to 6.3.2. to address exterior and interior locking devices and full locking systems with reference to master control switch deactivation and alarm or acoustic warning provisions,
• Insert new paragraph 6.4. prescribing intuitive operation of latch release controls and door handles, requirements for power-assisted systems to function after power loss for 60 minutes, and door handle design for opening after power loss,
• Insert new paragraph 7.3. requiring testing of power-assisted latch release controls and door opening systems in accordance with Annex 7,
• Insert new Annex 7 establishing a power loss test procedure to verify door opening functionality from interior and exterior following main power supply disconnection, with 60-minute wait before testing and door opening completion required within 80 minutes after power disconnection based on GRSP-78-20/Rev.1 and GRSP-78-48.

Discussions to amend GTR 1 to require doors providing direct access for occupants to be equipped with an intuitively accessible exterior latch release control or alternatively in close vicinity to the door. The document notes that “intuitive,” “discoverable,” and “in close vicinity” are subjective terms difficult to assess objectively. It suggests defining these terms through objective criteria such as untrained first-time user performance testing within a specified timeframe, standardized ISO symbols, defined proximity zones relative to the door, and requirements balancing accessibility against inadvertent operation risks.

Proposals developed during the EDO session to:

• Amend para. 1.1. to include application to evacuation of occupants in emergency events,
• amend definitions of child safety lock system, full locking system, and door closure warning system,
• insert new definitions of latch release control, door handle, retractable door handle, unlock, unlatch, power loss, vehicle master control switch, main power supply, and door opening,
• insert new para. 5.4. establishing requirements for exterior and interior door operation including latch release controls and door handles,
• amend para. 6.3.1. to reference exterior latch release control and insert para. 6.3.1.1. requiring full locking systems to activate only when vehicle master control switch is deactivated with specified measures,
• amend para. 6.3.2. for side rear doors,
• insert new para. 6.4. establishing requirements for intuitive operation of latch release controls and door handles, power-assisted systems capability after 60-minute power loss, and unobstructed positioning,
• insert new para. 7.3. requiring testing in accordance with Annex 7,
• insert new Annex 7 establishing power loss test procedures for interior and exterior door opening after main power supply disconnection.

The document addresses Part C verification of virtual distance for heavy-duty vehicle batteries. OICA reports pilot phase results from Volvo Group and Daimler Truck AG testing measurement procedures and accuracy under driving and stationary conditions. Key findings show measurement accuracy decreases significantly at lower power levels, with deviations of 0.3% to 4% at higher power. PTO system characteristics influence accuracy; internal PTOs performed better than bodybuilder-installed units. The document identifies challenges including formula correction needs, PTO family concept complexity, and proposes further testing before finalizing Part C requirements.

Proposal to amend footnote 25 to reduce the maximum number of recorded DCAS warnings from 15 to 10 per current ignition cycle. The justification presented cites data burden reduction while retaining information about habitual driver disengagement patterns. Supporting documentation references two autopilot collision cases—Florida 2016 and California 2018—where recorded warnings within existing data retention periods would have revealed repeated disengagement that current recording parameters miss, demonstrating that 10 warnings combined with extended recording duration enables identification of ineffective warning strategies.

Proposal to establish a submergence test procedure requiring that at least one window per row of seats be capable of being fully opened after a vehicle enters water for occupant escape, with the window operable up to 2 minutes after submergence as designed by the manufacturer, defining container dimensions to accommodate the vehicle without wall or floor contact during the 2-minute period except when fully submerged, permitting open-water test sites provided they comply with test conditions while prohibiting freshwater lakes, reservoirs, and saltwater bodies, requiring the master control switch position allow window operation, specifying unladen kerb mass with measuring apparatus not changing axle reference load by more than 5 per cent, lowering the vehicle into water-filled container at horizontal angle 0–10 degrees with time zero defined as when lowering straps become slack and vehicle floats freely, requiring the vehicle remain in water for 2 minutes from time zero without floor contact until fully submerged, requiring window operation by remote system after 2 minutes with vehicle immersed, and permitting alternative subsystem tests demonstrating window opening functionality under submerged conditions.
