The world's first global technical regulation for autonomous driving systems cleared its final hurdle on June 24, giving automakers a unified safety baseline across major markets.
The United Nations approved the world's first global technical regulation for automated driving systems on June 24, creating a unified safety framework that will take effect in January 2027 across more than 60 countries.
"This is a major step for road technology," said Richard Damm, who leads the UNECE group on automated vehicles. "Bringing all the world's major automotive powers onto a single framework did not mean weakening any underlying technical safety requirements."
The regulation, known as ADS GTR, was co-led by China, the European Union, the United Kingdom, the United States, Canada and Japan. It was adopted at a Geneva meeting of the World Forum for Harmonization of Vehicle Regulations (WP.29). The framework sets core requirements for safety management processes, product documentation, end-to-end testing and post-deployment monitoring, creating a regulatory architecture that spans the full product lifecycle.
The approval arrives as autonomous driving technology accelerates toward commercial scale. Robotaxi fleets in the US and China more than doubled in 2025 to 8,000 vehicles across more than two dozen cities, and the International Energy Agency projects 700,000 to 3 million robotaxis operating in 40 to 80 major cities by 2035. Without a common rulebook, automakers faced a patchwork of national standards that could have prevented vehicles built for one market from being sold in another.
To accommodate the complex web of international vehicle rules, the same set of standards was approved through two separate votes. The first track added the ADS GTR to the 1958 international vehicle agreement, under which over half of the 62 participating countries voted in favor. Vehicles validated under this track can be sold directly across member nations without secondary regulatory checks.
The second track used the 1998 agreement to integrate the United States, Canada and China — major automotive markets that are not parties to the 1958 treaty. While the 1998 framework does not guarantee automatic cross-border acceptance, it ensures that autonomous software and hardware will be manufactured to an identical baseline standard worldwide.
François Guichard, secretary of the UNECE's GRVA working group, said several manufacturers are already preparing to comply with the rules, which are expected to become mandatory in the European Union by the end of 2026.
China played a leading role throughout the regulatory development process. The Ministry of Industry and Information Technology organized research institutes and industry partners to contribute dozens of technical proposals and share real-world testing data from closed-course, public-road and vehicle-infrastructure collaborative trials.
At the same time, China has finalized its own mandatory national standard for automated driving systems, which is undergoing approval procedures. The standard fully aligns with the ADS GTR while refining requirements for Level 3 and Level 4 systems. It sets clearer safety baselines for different automation levels, strengthens user training and disclosure mechanisms, and introduces standardized test scenarios built on the internationally accepted multi-pillar approach.
Sun Hang, chief engineer of the China Automotive Standardization Research Institute, said the complexity and diversity of Chinese urban driving scenarios serve as an unrivaled testing ground. "Systems validated in the country possess strong global adaptability and acceptability," he said. China's penetration rate of new vehicles equipped with advanced driver-assistance systems has already exceeded 60 percent.
In December, the MIIT granted road approval for two L3 electric sedan models — one from Changan Automobile and one from BAIC Motor's Arcfox — marking the first time the ministry allowed such vehicles on public thoroughfares. The Changan model is limited to single-lane autonomous driving at speeds of up to 50 kilometers per hour in traffic congestion on specific Chongqing expressways, while the Arcfox can operate at up to 80 km/h on designated Beijing highways.
For automakers and technology companies developing autonomous systems, the new global framework reduces regulatory uncertainty and creates a clearer path to commercialization. Companies that can demonstrate compliance against the shared baseline — including XPeng Motors, which was deeply involved in the regulatory process, along with Tesla, Baidu and Alphabet's Waymo — stand to benefit as the market scales from thousands of test vehicles to potentially millions of robotaxis over the next decade.
