NHTSAProposed Rule

Federal Motor Vehicle Safety Standards: No. 216 and 216a; Roof Crush Resistance; Applicable Unless a Vehicle is Certified, Roof Crush Resistance

Transportation

Summary

This proposed regulation sets safety standards for how well car roofs can resist crushing in accidents, aiming to better protect passengers during rollovers and collisions. The rule applies to most vehicles unless manufacturers meet specific safety certifications, and the government is seeking public feedback on the proposal through July 30, 2025.

Key Points

  • 1The rule establishes minimum strength requirements for vehicle roofs to prevent them from collapsing during accidents and rollovers
  • 2Car manufacturers must either meet these roof crush resistance standards or obtain a safety certification exempting their vehicles
  • 3This regulation applies to passenger cars, trucks, and SUVs to improve occupant protection in serious accidents
  • 4The public has until July 30, 2025 to submit comments and concerns about the proposed rule
  • 5Compliance with these standards may require automakers to use stronger materials or redesign roof structures

Impact Assessment

If you are a vehicle manufacturer, this means you must engineer and test car roofs to meet new crush-resistance standards unless you obtain specific safety certifications, increasing production and testing costs.
