The initial regulations for Driver Drowsiness and Attention Warning and Advanced Driver Distraction Warning systems were adopted at GRSG-130 and WP.29-198. DDADWS is developing 01 series regulations, with workshops and online meetings planned. The group seeks a mandate extension to October 2028 to complete 01 series development, with proposed submission for approval to GRSG-136.

Proposal to extend the mandate of the DDADWS informal group until October 2028 to enable development of new (01) series of amendments to the original texts of the driver drowsiness and driver distraction warning systems regulations.

Proposal to correct cross-references in UN R73. The amendments modify paragraphs 12.1, 15.1, and Annex 3, paragraph 2.4 to replace incorrect paragraph citations with accurate ones. The corrections address invalid references that do not exist or lack contextual relevance. The changes do not increase requirement stringency.

Proposal to correct cross-references in UN R73. The document amends paragraphs 12.1, 15.1, and Annex 3 paragraph 2.4 to correct invalid or non-existent paragraph references. Changes include updating references from paragraphs 12.4.4 and 15.2.4 to 12.4.2/3 and 15.2.2/3 respectively, and replacing the non-existent paragraph 2.8 reference with paragraph 12.10. The corrections do not increase requirement stringency.

Proposal to introduce provisions for rollover protection systems, advanced emergency braking systems, vulnerable road user secondary safety systems, and driver assistance systems. Amendments clarify triggering conditions for event recording and data locking, expand data elements to capture vulnerable road user collisions and advanced safety system interventions, increase sample rates for improved data granularity, and add transitional provisions for type-approval acceptance timelines.

Proposal to amend UN R169 by inserting definitions for non-volatile and volatile memory, and modifying the Last Stop trigger criteria. The amendment allows threshold criterion (a) data to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates. This reduces memory wear in vehicles with frequent stops exceeding 20 seconds.

CLIV is developing a new UN Regulation for vehicle categories M1, M2, M3, and N1 in Phase 2. The draft regulation requires visual and audible external warnings upon detection of a child left in a vehicle. Visual warnings use direction indicator lamps flashing in SOS morse code pattern for at least 15 seconds, then off for no more than 30 seconds, repeating for at least 10 minutes. Audible warnings must exceed 60dB(A) following the same timing pattern. The IWG requests guidance on potential amendments to UN R48, UN R28, and UN R165.

Five documents propose amendments to UN R46 series 02-07 to align requirements with UN R26 and UN R61, particularly regarding soft parts of camera monitoring systems and mirrors based on Shore A hardness. The 05 series introduced alignment requirements; harmonization is proposed for earlier series with existing approvals.

Proposal to amend UN R158 to include category O vehicles (trailers) within the scope of regulations for devices enabling driver awareness of vulnerable road users during reversing. The amendment aims to reduce safety risks to vulnerable road users when category O vehicles reverse. Amendments modify title, paragraphs 1.1, 1.2, 1.4, 12.3, 12.4, and Annex 4, and introduce transitional provisions starting from September 2028. Justification includes casualty data showing seven fatalities and 15 serious injuries over 10 years from vehicles towing trailers reversing into vulnerable road users, plus a coroner’s recommendation for reversing cameras on all vehicles.

The document highlights WP.29 sessions from November 2025 and March 2026. Topics include mirror foils on vehicles requiring multi-working party coordination, categorization difficulties for three-wheeled dump trucks under R.E.3, and promotion of global representation in officer elections for WP.29 and subsidiary groups. The Vulnerable Road Users Informal Working Group was dissolved. GRSG may adjust priorities following a workshop on Door Opening Warning Systems. AC.3 discussed revising interim election agreements to broaden participation beyond original principal negotiators.

Proposal to clarify opaque obscuration in indirect vision devices. The proposal inserts a definition of opaque obscuration and amends paragraph 15.1.4 to correct a reference to UN R43, Annex 24 rather than Annex 21. Paragraph 15.2.4.9.1 is amended to exclude areas of opaque obscuration from obstruction calculations for Class I rear-view devices, treating them similarly to mandatory rubber sealings used for window mounting.
