The IWG on DETA discussed system operations showing 118,000 uploaded approvals with 41 contracting parties accessing the platform. Topics included widening scope to non-1958 Agreement parties, potential regulation updates for brake emission parts, renaming DETA to reflect broader applications, guidance on data exchange for ADS vehicles, adding attributes for series compliance, and granting read-only access to candidate countries. A June workshop will promote IWVTA and DETA adoption.
