A new UN Regulation is being drafted for N₁vehicles of category Y (vehicles equipped with an automated driving system, not capable of manual driving exceeding 6 km/h, and not designed to carry occupants). The draft incorporates crash safety requirements from UN R94, UN R95, UN R137, and UN R153. Draft version 5 adds provisions for simplified approval procedures for previously approved vehicles, references UN R137 for vehicles between 2,500 and 3,500 kg, and clarifies B pillar references. Open issues include confirming non-applicability of lateral collision partial tests and clarifying which simplified procedures are permitted.

A decision was taken in mid-2025 to start drafting a new regulation collecting relevant safety requirements for Category Y vehicles. UN R127 on pedestrian safety performance could be directly amended to include Y-category vehicles instead of including requirements in a new regulation. TF AVRS agreed to amend UN R127 to include Y-category vehicles. A draft regulation (v4) is available proposing supplement 5 to the 04 series of amendments, including amendment suggestions in scope to determine exemptions for Y-category vehicles based on front structural geometry dimensions rather than R-point criteria.

Proposal to finalize a status report on Amendment 1 to UN Global Technical Regulation No. 20 on electric vehicle safety. The IWG-EVS conducted Phase 2 work addressing topics including water immersion tests, fire resistance, battery rotation and vibration, thermal propagation, and charging safety. The group maintained existing regulatory text except for thermal propagation provisions. Two compliance paths were developed: a physical test method with five initiation options and a risk management approach. Phase 3 will address thermal propagation scope expansion, post-crash safety, in-use battery maintenance, swappable batteries, light vehicles, gas emissions criteria, and bottom protection.

Proposal to amend UN Global Technical Regulation No. 20 on electric vehicle safety, focusing on thermal propagation triggered by single-cell thermal runaway. The amendment introduces two compliance paths: a physical test approach with five initiation methods (external heater, internal heaters, nail penetration, laser-based initiation) performed at vehicle or component level; and a risk management approach requiring manufacturers to document known risks and mitigation strategies. Vehicles must provide advance warning 5 minutes before hazardous conditions (fire, explosion, smoke) occur in the passenger compartment. Phase 2 discussions concluded that water immersion tests, long-term fire resistance tests, REESS rotation tests, vibration profile modifications, AC/DC charging protections, and heavy-duty overcurrent tests do not require regulatory inclusion based on available field evidence and safety analysis.

Proposal to amend para. 5.3. to require that the effectiveness of ELKS shall not be adversely affected by magnetic or electrical fields, demonstrated by fulfilling the technical requirements and respecting the transitional provisions of the 06 series of amendments to UN Regulation No. 10.

Proposal to amend row 13© of the List of proposed decisions on the documents reviewed during the informal consultations (GRVA-25-04/Rev.2) to specify that GRVA partly included the work on DSSAD within the IWG on ADS remit, with items to be included comprising strategic directions and data elements structured as a separate workstream under an OPI’s coordination, and DSSAD activities related to data format, accessibility, survivability and location becoming part of IWG on EDR activities, with regular online meetings organized to ensure alignment and coordination between the two groups.

Proposal to amend guidance on continuous improvement processes in para. 7.1.8.2. by inserting text stating that post-deployment safety analyses are systematically performed for all occurrences; however, their conclusions do not necessarily result in the identification of a corrective action from the manufacturer, modifying text to state that not all identified corrective or preventive actions need to be implemented in order to close an occurrence, and replacing text to state decisions on what to address and how are based on an overall assessment of the consequences and the impact of implementing a change.

Proposal to amend Annex 4 – Data elements and format, Table 1, modifying Advanced driver distraction warning (ADDW) data elements to record status and time since warning issued instead of number of warnings and time elapsed since last warning, modifying Driver control assistance system (DCAS) driver monitoring system data elements to record time since disengagement warning issued and warning type instead of number of hands-on requests, eyes-on requests, direct control alerts, and time elapsed since last warning, and adding Driver drowsiness and attention warning (DDAW) status and time since warning issued data elements while removing number of warnings and time elapsed since last warning, with ADDW and DDAW elements listed up to five times for most recent warnings and DCAS warning type listed up to fifteen times for most recent warnings on current trip.

Proposal to add retrieval of DSSAD time-stamp data elements recorded for at least the last 30 seconds before the last setting of the event flag “Event Data Recorder (EDR) trigger input” alongside EDR data through the same interface, add provisions for retrieval when no such event occurs within the last 30 seconds, add provisions to replace date and time with relative time information when required by national or regional law, and add detected collision by Automated Driving System as an EDR trigger for UN R160 and UN R169.

Proposal to amend UN R160:

• Amend definitions 2.8., 2.10., and 2.11. to clarify that automatically commanded steering function categories B2, D, and E are not part of a DCAS
• Delete definition 2.25.
• Amend definition 2.35. to simplify non-volatile memory
• Amend para. 2.45. to change service brake terminology
• Amend para. 2.51. to clarify time interval between events
• Amend para. 2.65. to abbreviate vulnerable road user
• Insert new definitions 2.71.–2.83. for rollover protection system, advanced emergency braking system, trigger activated, pre-event synchronization timer, blind spot monitoring system, emergency stop signal, turn signal, acceleration control for pedal error, advanced driver distraction warning system, driver drowsiness and attention warning system, driver control assistance system, and time to collision
• Restructure para. 5.3.1. to distinguish planar, VRU, and rollover events from AEBS events with specified triggers
• Amend para. 5.3.2. to clarify data locking conditions
• Restructure para. 5.3.3. to establish time zero for planar, VRU, rollover, and AEBS events
• Amend para. 5.4.3. to specify side and frontal collision tests
• Amend para. 6.1. to clarify post-crash acceleration measurement
• Insert transitional provisions 12.12.–12.16. providing that as from the official date of entry into force Contracting Parties shall not refuse type-approvals under the 03 series, as from 1 September 2031 or 2029 [date TBD] shall not accept type-approvals to preceding series first issued after that date, until 1 September 2033 shall continue accepting preceding series approvals first issued before 1 September 2031 or 2029 [date TBD], may grant approvals to preceding series, and shall grant extensions of existing approvals
• Amend Annex 4 Table 1 to split engine throttle and accelerator pedal data elements, increase sampling rates to 10 Hz, extend recording intervals for rollover events, add pre-event synchronization timer, trigger activated, ACPE status, ADDW status, DDAW status, blind spot monitoring status, turn signal status, DCAS status, DCAS driver monitoring system warnings, emergency stop signal status, and time to collision data elements, and modify footnotes accordingly

Proposal based on GRSG/2026/38 to amend para. 2.18. to define end of event time separately for planar events and all other events, amend para. 2.20. to redefine engine throttle percent full, insert new definitions for Advanced emergency braking system (AEBS) and Trigger activated, amend para. 5.4.3. to modify crash test data requirements and reference UN Regulations Nos. 95 and either 94 or 137, and amend Table 1 in Annex 4 to modify data element requirements including changing Air bag warning lamp and other elements from conditional to Mandatory, adding AEBS event recording, modifying Yaw Rate recording intervals and sample rate, clarifying Vulnerable road user secondary safety system warning indicator status recording, modifying Accident emergency call system status recording interval, and revising footnotes regarding TTC calculation and AEBS requirements, effective upon entry into force of the 03 Series of Amendments.

European Commission priorities for EDR Step 3 include improving detection of vehicle-to-vulnerable road user collisions and low-severity vehicle-to-vehicle collisions through adjusting delta-v trigger thresholds, developing new jerk-based trigger criteria, and exploring ADS collision detection for EDR triggering in automated vehicles on a long-term timeline. Data elements and format must be ensured to remain up-to-date with new safety system developments and close gaps between light and heavy vehicles through reviewing data elements in light of newly regulated safety systems and mirroring DDAW, ADDW and DCAS data elements from UN R160 to UN R169 on short-term and ongoing timelines.

Proposal to clarify that the EDR volatile memory buffer for last stop trigger activation shall accommodate data related to at least five different stops to be overwritten on a first-in first-out basis, and that data for the most recent stops shall be written to non-volatile memory in a way that does not interfere with the event record related to any other trigger of paragraph 5.3.1.

For vehicles equipped with an Automated Driving System, it shall be possible to retrieve DSSAD time-stamp data elements specified under paragraph 5.2. of Annex 8 of UN Regulation No. 185 recorded within at least the last 30 seconds prior to triggering of the respective EDR event, regardless of whether the DSSAD and the EDR are implemented as a single system or as separate systems. The time-stamp data elements retrievable from the DSSAD shall include the record for the last activation or deactivation of the feature used at the time of the event within the same power cycle. The data elements shall be retrievable in the format specified in Annex 8 of UN Regulation No. 185, though DSSAD location data may be omitted and dates and times recorded may be replaced with information representing the time elapsed between the recording of each DSSAD data element and the triggering of the EDR.

SLR will deliver Stage 2/Step 2 to GRE-96 by end of January 2027 for submission to WP.29 in November 2027. SLR’s mandate ends December 2027. A new informal working group on Supporting technical experts on Lighting Regulation (SteLR) will be established, chaired by EC and vice-chaired by Germany, to address remaining open points from SLR and TF-GP. Main topics include visibility of signalling functions, glare prevention, apparent surface, energy saving, replaceability and sustainability, and V2X communication.

The document establishes procedures for demonstrating equivalence between vehicle circuit and indoor drum test facilities. It defines requirements for selecting exercise tyres and participating facilities, establishing baseline values from multiple facilities, and comparing facility results against baselines. For indoor drum facilities, transfer functions mathematically relate drum results to vehicle results, either as generic (fixed coefficient) or specific (facility-determined coefficient). Facilities must meet statistical criteria including result deviation limits and root mean square deviation thresholds to demonstrate equivalence.

Cooperative intelligent transport systems (C-ITS) enable ITS users to interact and cooperate by exchanging secured and trusted messages without prior knowledge of each other and in a non-discriminatory manner. The EU C-ITS security credential management system has three central roles that the Commission shall be responsible for ensuring are executed. Priority area IV is dedicated to ITS services for Connected and Automated Mobility (CCAM). Work on specifications under the ITS Directive will restart in 2026, covering the EU C-ITS security credential management system, harmonised C-ITS services, and fostering development and implementation of C-ITS. Currently, 2.5 million vehicles are sold and 20,000 km of roads are equipped with C-ITS, with 100,000 km covered by C-ITS services across more than 50 European cities in 21 European countries.
