Summary

NHTSA intends to issue comprehensive, updated guidance supporting the safe development and deployment of automated driving systems. The last agency guidance was published in 2017, titled Automated Driving Systems 2.0: A Vision for Safety (ADS 2.0). For this initiative, NHTSA will draw on its internal expertise and public feedback gathered through ongoing stakeholder engagement. NHTSA intends to release draft guidance documents on individual topics (or chapters) as they are available. The public is invited to comment on each chapter through this open docket. After reviewing public comments, the agency plans to consolidate all chapters into a final updated guidance document. The public comment period is open for one year and may be extended as necessary.
