EC presented a draft on UN R42, with NL proposing additions regarding automated driving systems exemptions and introduction text; EC to update the draft accordingly. UN R134 Y-category exclusion was listed with no discussion recorded.

Agenda for the 29th meeting of the GRSP Task Force on Advanced Vehicle Regulatory Support, scheduled for 5 October 2026. The meeting will address Y-category regulatory framework developments for N1 vehicles, Y-category pedestrian protection under UN R127, UN R42 matters from GRSP-79, Y-category exclusion in UN R134, and other business.

Clean work-in-progress draft proposal to amend para. 0 to introduce provisions for vehicles of category Y and vehicles equipped with an Automated Driving System, amend para. 1.4. to specify that the Regulation does not apply to vehicles of category Y and to exempt certain vehicles of category N₁, amend para. 2.8. to define the bonnet rear reference line for vehicles of category Y without a windscreen, amend para. 2.22. to include automated driving sensors in the definition of front structure for vehicles of category X and Y, amend para. 2.29. to specify normal ride attitude for vehicles of category X and Y, amend para. 2.32. to define side reference lines for vehicles of category Y without A-pillars, amend para. 2.44. to define windscreen test area boundaries for vehicles of category Y without a windscreen, amend para. 2.45. to specify cowl monitoring area for vehicles of category Y without a windscreen, and amend para. 5.3.1.2. to modify requirements for Actively Regulated Hydro-pneumatic Suspension System when an Automated Driving System feature is active.

Work in progress clean draft proposal to establish a new UN Regulation on crashworthiness of vehicles of category N₁Y with regard to protection of fuel system integrity, protection against electrical shock and vehicle crash compatibility in the event of frontal, rear-end and lateral collision. The regulation applies to vehicles of category N₁Y and specifies test procedures for frontal, lateral and rear-end collisions based on UN R94, UN R95, UN R137 and UN R153. Requirements include fuel system integrity with no more than slight leakage or continuous leakage not exceeding 30 g/min, hydrogen leakage rate not exceeding 118 NL per minute, protection against electrical shock through absence of high voltage, low electrical energy, physical protection or isolation resistance, electrolyte leakage limits, REESS retention and fire hazard prevention, and crash compatibility criteria with Crash Compatibility Criterion not exceeding 40–45 g and Crash Compatibility Value not exceeding 100–120 gt.

Clean work-in-progress draft proposal to insert a new para. 0 establishing an introduction for vehicles of categories X and Y equipped with an Automated Driving System, and amend para. 6.1.5. to clarify that the exemption for sensors, cameras, and radar devices being part of driver assistance systems does not apply to automated driving systems unless the ADS performance of the DDT is not affected.

Proposal, updated with in session comments, to amend Footnote 1 to reference document ECE/TRANS/WP.29/78/Rev.8, amend para. 6.1.5. to clarify that the exemption for sensors being part of driver assistance systems does not apply to automated driving systems, remove non-exhaustive examples of sensors, replace “disoriented” with “misaligned”, and align terminology to “driver assistance systems”. The exemption for driver assistance systems is retained because their failure does not prevent manual vehicle operation, whereas automated driving systems’ perception equipment forms part of the driving function, and damage to sensing devices may prevent vehicle operation contrary to Regulation No. 42’s objective.

Proposal to insert a new introduction section defining application to vehicles of categories X and Y equipped with an Automated Driving System, to amend para. 6.1.5. to replace “driver assist systems” with “driver assistance systems”, to remove the non-exhaustive list “cameras, radar devices, etc.”, to replace “disoriented” with “misaligned”, and to add provisions clarifying that the exemption for sensor damage does not apply to automated driving systems unless the Automated Driving System performance of the Designed Driving Task is not affected.

This Regulation establishes uniform provisions for crashworthiness approval of N₁Y vehicles regarding fuel system integrity, electrical shock protection, and crash compatibility during frontal, rear, and lateral collisions. The provisions for frontal impact are based on UN R94 or UN R137 per manufacturer choice with Technical Service agreement; lateral impact provisions are based on UN R95; rear impact provisions are based on UN R153. Vehicles with maximum design speeds not exceeding applicable impact speeds shall be tested at their maximum design speed and comply with post-impact requirements. Crash Compatibility Criterion shall not exceed 40–45 g and Crash Compatibility Value shall not exceed 100–120 g×tonne. For vehicles derived from types already approved under UN R94, UN R137, UN R95, or UN R153, previous test results may be used if mass increases do not exceed 8 per cent.
