China's Ministry of Industry and Information Technology has formally approved GB 44721-2026, the country's first national standard specifically addressing L3 and L4 autonomous driving systems. The standard is scheduled to come into force on July 1, 2027.
At the heart of the new regulation is a transition away from assessing performance at the single-vehicle level toward ensuring safety across the entire product lifecycle. Automakers will now be required to show safety governance spanning research and development, production and operations after deployment, rather than relying on one-off vehicle certifications.
The regulatory framework reassigns primary accountability from individual vehicles to the manufacturing enterprise. Under GB 44721-2026, manufacturers must create and maintain comprehensive lifecycle safety-management systems that cover development, manufacturing, deployment and post-deployment activities. Under this approach, certifying a single vehicle will not satisfy compliance obligations.
The standard also makes explicit the types of validation that must be performed. Simulation, closed-course testing and on-road testing are now laid out as required elements of the validation process. This converts what has often been an engineering or commercial choice about how to demonstrate system behavior into a formal compliance obligation.
Specific operational controls receive attention as well. The standard prescribes requirements for system activation procedures, clear status indication to users, and monitoring of driver readiness for takeover - provisions that are particularly relevant for Level 3 systems where the transition between automated and manual control creates notable safety considerations.
GB 44721-2026 integrates enterprise capability reviews, the maintenance of safety archives and confirmatory testing into a single oversight architecture. The emphasis moves beyond proving that a system can work in isolated tests to demonstrating that safety can be continuously verified and documented throughout a system's lifecycle.
Investment bank Jefferies commented that the standard changes the competitive landscape. According to Jefferies, the focus shifts from product attributes alone to organizational strengths - including access to data, robustness of safety governance and the economies of scale required to run continuous validation programs. The bank suggested this framework should bolster the positions of established automakers while increasing the compliance burden on smaller electric vehicle companies that rely heavily on suppliers and lack scale.
Jefferies additionally noted potential advantages for leading Tier 1 suppliers as automakers seek validation support, safety case evidence and compliance services rather than simply purchasing hardware or isolated algorithms.
Summary
GB 44721-2026, China's first national standard for L3 and L4 autonomous driving, mandates lifecycle safety-management by automakers, requires simulation, closed-course and on-road testing, and sets operational rules for system activation and driver takeover monitoring. The rule is effective July 1, 2027. Jefferies says the regime favors larger automakers and Tier 1 suppliers while raising hurdles for smaller EV companies.
Key points
- Regulation shifts compliance from single-vehicle certification to a manufacturer-level lifecycle safety-management framework - impacting automotive manufacturers and suppliers.
- Simulation, closed-course and on-road testing are explicitly required, making validation infrastructure a regulatory necessity - relevant to testing service providers and engineering teams.
- Jefferies sees competition moving toward organizational capabilities such as data, governance and scale, benefiting leading automakers and large Tier 1 suppliers while increasing burdens on smaller EV makers.
Risks and uncertainties
- Smaller electric vehicle manufacturers that depend on suppliers and lack scale may face higher compliance costs and operational burdens under the new standard - affecting the EV manufacturing sector.
- Automakers must develop and maintain lifecycle safety-management systems; failure to do so could result in non-compliance or operational constraints - relevant across automakers and mobility service providers.
- Increased demand for validation, safety archives and confirmatory testing could strain existing testing infrastructure and supplier relationships if capacity or capability is insufficient - impacting Tier 1 suppliers and testing firms.
