The UN World Forum for the Harmonization of Vehicle Regulations (WP.29) enables governments to cooperate internationally in developing vehicle regulations concerning safety, environmental performance, and energy efficiency.
GlobalAutoRegs is a technical resource for members of the regulatory affairs community interested in this international collaboration.
| ADS guidance and interpretation document: Proposal to explain para. 8.3.3.1.1. |
| Reference Number: ADS-20-52 |
|
Proposal to explain para. 8.3.3.1.1. The revised text clarifies that relevant standards supporting the assessment of laboratories could include ISO/IEC 17025 Testing and calibration laboratories, which sets requirements for competence, impartiality, and consistent operation. Applied to ADS testing, it ensures measurements are traceable, validated, and reproducible so results are technically reliable and defensible for approval/certification purposes. However, there is no obligation for the manufacturer or third-party organization involved in the testing to be accredited according to ISO/IEC 17025. |

| ADS guidance and interpretation: Proposal to explain para. 8.3.2.4.1.4. |
| Reference Number: ADS-20-53 |
|
Proposal to explain para. 8.3.2.4.1.4. The revised text divides guidance between ADS users and other road users. For ADS users, representativeness means including a range whose behaviours, skills, and characteristics reflect those reasonably expected to use the ADS, with testing not limited to engineers. For other road users, representativeness means capturing a sufficiently broad range of real-world behaviours and characteristics relevant to the ODD. The revised proposal also addresses statistical significance, encouraging manufacturers to provide calculations explaining their choice of participant numbers and underlying assumptions. |

| ADS guidance and interpretation: Proposal to explain para. 7.3.2.14 |
| Reference Number: ADS-20-54 |
|
Proposal to explain para. 7.3.2.14. The revised text simplifies the definition of ‘sufficient’ to refer to the scope of tests performed on the fall-back response. With respect to scenarios, the manufacturer is encouraged to describe reasoning behind scenario choice and justification for the overall number chosen, acknowledging that scenario diversity depends on intended use case and operational design domain. References to user numbers and statistical methods for sample size assessment have been removed. |

| ADS guidance and interpretation: Proposal to explain para. 8.3.2.1.2. |
| Reference Number: ADS-20-55 |
|
Proposal to explain paragraph 8.3.2.1.2. The revision clarifies that coverage can be evaluated based on the following items and their interdependencies: Operational Environment, Behavioural competency, Scenario-type/category, and Rules of road compliance. A footnote acknowledges that no single item alone can robustly document coverage. |

| ADS guidance and interpretation: Behaviours and ODD in safety cases |
| Reference Number: ADS-20-46/Rev.1 |
|
Proposal to amend Paragraph 5.3.1.3 (GTR) / 7.3.1.3 (UNR) in Safety Case. The revision replaces “no new behaviours or traffic flows” with “no new behaviours or traffic flows density or dynamic element types” and adds “or traffic behaviour” to the text regarding traffic laws because ODD does not include a definition of traffic behaviour, making the original sentence factually incorrect. |

| ADS guidance and interpretation: ODD-related terminology |
| Reference Number: ADS-20-47 |
|
Proposal to amend paragraph 5.3.1.3 (GTR) / 7.3.1.3 (UNR) in Safety Case. The revised text adds “attributes and their respective values” to replace “parameters” in the sentence about links/dependencies between ODD parameters, to ensure consistent terminology and reflect that dependencies exist not only between attributes but also between their values. |

| Energy Saving Opportunities in Automotive Lighting: GTB Activities Status Report |
| Reference Number: GRE-94-54 |
|
A 2025 study by TU Darmstadt concluded that a daylight running light passing-beam switching threshold of 500lx is preferable at sunset, and that adaptive DRL values lower than 400cd seem sufficient. The GTB is developing amendment proposals for DRL/low beam switching thresholds, adaptive DRL, and Class V ECO mode. Annual energy saving potentials range from 55 GWh to 141 GWh across evaluated use cases, with highest savings from DRL intensity adaptation and reduced low beam in city nighttime driving. |

| UN R10 : IWG EMC Status report |
| Reference Number: GRE-94-53 |
|
IWG EMC prepared supplement 3 to the 07 series of amendments to UN R10, with terminological adjustments for ADS adoption, addition of categories X and Y, technical refinement of ADS including a new ADS table in Annex 6 paragraph 2.1.1.2, and modifications to artificial networks with discharge voltage below 50 V and maximum discharge time of 20 seconds. For the 08 series, approved proposals are prioritised on a roadmap. |
