Proposal to enable application of UN R17 to certain vehicles equipped with an Automated Driving System.

Proposal to enable application of UN R16 to vehicles equipped with an Automated Driving System.

Document as updated during the 24th AVSR session (March 2025). Also available with tracked changes and comments.

Proposal from the GRSG task force on Automated Vehicles Regulation Screening to exempt vehicles of subcategories X and Y from the requirements and limit the requirements for other vehicles equipped with an ADS and when an ADS feature is active.

Proposal to amend para. 5.2.3.2.2., para. 5.2.3.2.3., para. 5.2.3.2.4., and para. 5.2.3.3. to establish requirements for vehicles of category X and Y equipped with an ADS regarding speed warning labels and information provision to the ADS about speed capacity of fitted tyres, and amend Annex 2 to include provisions for describing the automated driving system and the modes tested with ADS operation.

Proposal to modify para. 2.13. to define “Run-Flat Warning System” to deliver information to the driver or the ADS, modify para. 5.1.6.1. to require optical yellow warning signals to the driver and logical signals to the ADS when an ADS feature is active, modify para. 5.1.6.3. to require warnings indicated to the ADS by logical signal when an ADS feature is active, modify para. 5.1.6.4. to require logical signals to the ADS for electrical failure or sensor anomaly when an ADS feature is active, modify para. 5.1.6.5. to require description in the owner’s manual of corrective action expected by the ADS, modify para. 5.1.7. to exempt vehicles of categories X and Y from inflation device requirements, modify para. 6.1.2.2. to require instructions on informing the ADS of temporary-use spare unit fitting, modify Annex 3 para. 2.2. and 2.3. to apply special provisions for ADS vehicles, modify Annex 4 paras. 2.1. and 2.2. to apply special provisions for ADS vehicles, and add Annex 5 specifying test adaptations for ADS vehicles.

Proposal to prohibit operation of DCAS while an ADS feature is active.

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.

Seven UN Regulation proposals were reviewed for consistency and errors. Issues identified include: unclear optical-logical signal transitions in R64; redundant definitions that should reference RE3 via footnotes; inconsistent ADS activity terminology requiring standardization to “when an ADS feature is active”; incorrect Category Y vehicle references in R51; spelling and numbering errors across multiple regulations; inconsistent Mass in Running Order definitions; and unclear testing provisions requiring improved cross-referencing. Corrections are necessary for regulatory robustness.

UN R127 amendment proposals include defining pedestrian protection requirements for category Y vehicles. Scope exemptions for category Y vehicles shall use front structural geometry to determine exemptions, ensuring equivalence to R-point criteria. Definitions require adjustments including Bonnet Rear Reference Line for vehicles without windscreens, Front structure definition to include automated driving sensors, Windscreen test area redefined as Upper structure test area where windscreens are non-existent, and supporting definitions for Side reference line and Cowl monitoring area. Testing shall occur at Unladen Vehicle Mass.

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.
