The mandatory national standard GB 21670-2025, formulated by the Ministry of Industry and Information Technology, has been approved and will come into effect on January 1, 2026. This standard introduces specifications for electric transmission braking systems, including detailed standards for electric regenerative braking and emergency braking signal requirements. Notably, it prohibits vehicles from decelerating to a stop solely by releasing the accelerator pedal under default settings, mandating that drivers must use the brake pedal to initiate braking. Tesla's official customer service has confirmed that they have not yet received any related adjustment notices, and that existing models adhere to current regulations. The new regulations are aimed at enhancing braking system safety, mitigating the risk of rear-end collisions, and steering the automotive industry towards safer and smarter advancements.
