Summary: A draft global regulation for Automated Driving Systems (ADS) has been adopted by UNECE’s GRVA, establishing harmonized safety and validation requirements for deploying fully driverless vehicles on public roads. Following a decade of technological maturation and regulatory groundwork, the proposal sets out a structured safety-case framework and uniform technical provisions, with formal adoption by WP.29 expected in June 2026.
Key engineering takeaway: The regulation formalizes a safety-case-based approval process requiring a certified Safety Management System, validated testing methodologies (including virtual toolchains), in-service monitoring and reporting, and a Data Storage System for Automated Driving (DSSAD). Manufacturers must demonstrate through structured claims, arguments and evidence that their ADS operates without unreasonable risk across defined operational domains.
Why it matters: A harmonized global framework reduces regulatory fragmentation and enables scalable deployment of Level 3/4 autonomous vehicles across major markets. By anchoring approval in lifecycle safety governance and continuous monitoring, the regulation strengthens public trust while giving industry a clear pathway from R&D to commercial driverless operation.
A draft ADS regulation by the UN will allow the deployment of autonomous vehicles of public roads
A decade ago, automated driving was widely forecast to be on public roads by 2020. However, while technology progressed, the task proved more complex than anticipated, requiring sustained research and development, as well as a clear, trusted regulatory path.
After 10 years of technological maturation and regulatory developments, as well as two years of intensive consultations and drafting, a draft global regulation on Automated Driving Systems (ADS), will allow deployment of autonomous vehicles with no supervision by a driver, on public roads.
The proposal, adopted by the UNECE Working Party on Automated/Autonomous and Connected Vehicles (GRVA) at its last meeting (19 – 23 January 2026), establishes uniform safety provisions and a harmonized methodology for validating vehicles equipped with ADS, anchored in a safety case approach and robust research and development processes.
“The adoption of this draft regulation demonstrates the global relevance of UN-led regulatory platforms. Harmonized vehicle rules developed at UNECE are essential to avoid fragmented national approaches and thus maximize economies of scale, and to support safety, market access and innovation in the automotive industry,” said UNECE Executive Secretary Tatiana Molcean.
“The adoption of this draft demonstrates that safety, innovation and public trust can advance together. By working globally, we provide clarity to the industry and confidence to consumers” said Richard Damm, Chair of GRVA. “GRVA will continue elaborating regulations on automated driving functionalities for Level 2, 3 and 4”.
Origin and next steps
The draft regulation builds on the Framework Document on Automated Vehicles of 2022, which identifies key principles for the safety and security of automated vehicles, as well as the Guidelines and recommendation for ADS requirements, assessments and test methods to inform regulatory development, adopted in June 2024.
It will be submitted to the UNECE’s World Forum for Harmonization of Vehicle Regulations (WP.29) for adoption at its next session (23-26 June 2026). Before that, GRVA will finalize technical provisions regarding data collection for ADS. If adopted by the World Forum, the global regulation would enter into force immediately.
Towards worldwide implementation
It was announced by NHTSA during the session that the United States’ Department of Transportation published on 23 January 2026 a Request for Comment on this draft, to inform its official position in anticipation of the vote in June 2026.
China also indicated that they will draft their national standard following the structure of the global regulation and will also collect comments.
Japan indicated its satisfaction with the process and also welcomed the outcome of this hard work.
Several European Countries welcomed the creation of the global regulation.
Key features
The draft global regulation aims to meet the needs of diverse markets and foster innovation while ensuring the highest level of safety on the road. Its key features include:
- Safety Management System (SMS): lifecycle safety governance, processes and competencies are mandatory. The regulation includes the audit and certification of the SMS to ensure compliance with the requirements.
- Testing credibility: requirements to demonstrate the credibility of test environments and methods, including virtual toolchains.
- Safety Case: Manufacturers must demonstrate, via structured claims, arguments and evidence, that the ADS meets outcome focused requirements and is free from unreasonable risk. This body of evidence is subject to a comprehensive assessment.
- In-service monitoring & reporting (ISMR): this provides a feedback loop to ensure continuous performance monitoring and reporting to authorities that enable learning and corrective action.
- Data Storage System for Automated Driving (DSSAD): capability to record and store safety-relevant ADS performance data.
