Proposal to establish uniform provisions for the approval of motor vehicles with regard to their Automated Driving Systems, covering vehicles of categories M₁–M₃, N₁–N₃, L₆ and L₇.

Proposal for a UN GTR on Automated Driving Systems to establish harmonized worldwide provisions for ADS safety, applying to vehicles of categories 1 and 2. It requires manufacturers to implement a Safety Management System, conduct multi-pillar validation (virtual, track, and real-world testing), document a comprehensive safety case demonstrating the ADS capability to safely perform the entire Dynamic Driving Task, and establishes a post-deployment monitoring and reporting framework to promote safety over the life of ADS vehicles.
