Geneva, Switzerland — The United Nations World Forum for Harmonization of Vehicle Regulations (UN/WP.29) has officially approved and released the first-ever Global Technical Regulation on Automated Driving Systems (ADS GTR) during its 199th session held June 22-26, 2026, in Geneva.

The landmark regulation was jointly developed by China, the European Union, the United Kingdom, the United States, Canada, and Japan. It establishes uniform international safety requirements and a common methodology for validating vehicles equipped with automated driving systems.

Core Requirements

The ADS GTR sets clear technical benchmarks for ADS-equipped vehicles and mandates that manufacturers implement audited, lifecycle-wide safety management systems.

Key provisions include:

Safety Management Systems (SMS) : Manufacturers must establish and maintain safety governance covering the entire lifecycle of the ADS.

Safety Case Approach: Companies must provide structured evidence demonstrating that their ADS poses no unreasonable risk and operates at a safety level at least equivalent to a competent and careful human driver.

Testing & Validation: The regulation adopts a "multiple pillar" approach to testing, requiring credible validation across simulation, track testing, and real-world scenarios.

Data & Monitoring: Vehicles must be equipped with automated driving data storage systems and manufacturers are required to conduct in-service performance monitoring and reporting.

The regulation also introduces a operational design domain (ODD) framework, requiring systems to recognize their operational boundaries and safely disengage when conditions fall outside those limits.

China's Leadership Role

China played a pivotal role in shaping the regulation. Since 2019, China has served as Vice-Chair of the UN Working Party on Automated/Autonomous and Connected Vehicles (GRVA) and Co-Chair of the ADS Informal Working Group. The Ministry of Industry and Information Technology (MIIT) led the drafting of core sections, including technical background, principles, and foundational requirements, while contributing over 40 technical proposals on dynamic driving tasks, human-machine interaction, and test methods.

François E. Guichard, Secretary of the UNECE's GRVA, praised China's contribution, stating that China played "a significant and constructive role" and noting the country is "well positioned to continue shaping future international regulations and advancing global cooperation".

Impact on the Industry

Prior to this regulation, the absence of harmonized global standards forced automakers to navigate fragmented national requirements, often requiring redundant testing and certification for each market. The new framework replaces these fragmented approaches with a common international standard, offering regulatory certainty for manufacturers and enabling the safe scaling of innovation across markets.

"Major automotive markets including Canada, China, the European Union, Japan, the UK, and the United States have endorsed the regulation, signaling strong momentum toward global adoption," Guichard said.

Next Steps

While the ADS GTR establishes the technical framework for vehicle safety, full deployment of autonomous vehicles still requires individual countries to enact domestic legislation and establish operational rules of the road.

China is moving in parallel to finalize its mandatory national standard for automated driving systems, which is currently in the approval process. The domestic standard fully incorporates the core technical content of the ADS GTR while introducing additional detailed requirements for L3 and L4 systems tailored to China's industrial and regulatory context.
