What happened: NHTSA extended the public comment period for its Supplemental Notice of Proposed Rulemaking on the THOR-50M advanced crash test dummy by 30 days, following a request from the Alliance for Automotive Innovation. Key numbers: Comment period extended from October 22, 2026 to November 21, 2026. Why it matters: The extension gives commenters more time to respond to the SNPRM, which seeks input on an additional spine configuration and an alternative to the face foam for the THOR 50th percentile adult male dummy.
