Description:  TITLE: Federal Motor Vehicle Safety Standards; Minimum Sound Requirements for 
Hybrid and Electric Vehicles  
AGENCY: National Highway Traffic Safety Administration (NHTSA), U.S. Department of 
Transportation (DOT)  
ACTION: Final rule  
SUMMARY: This final rule amends the test procedure in section S6.7.3 of Federal Motor Vehicle 
Safety Standard (FMVSS) No. 141, Minimu m Sound Requirements for Hybrid and Electric Vehicles, 
as proposed in the 17 September 2019, notice of proposed rulemaking (NPRM), to specify the single 
point in time that should be used when determining one -third octave band levels of ambient noise

  measur ements used in compliance tests. The agency has chosen not to adopt the remaining portions 
of the NPRM, including a proposal which would have allowed manufactures of hybrid and electric 
vehicles (HEVs) to install a number of driver - selectable pedestrian a lert sounds in each HEV they 
manufacture. The driver -selectable alert sounds proposal is not being adopted because of a lack of 
supporting data. In addition, this final rule acknowledges that a proposed technical change included 
in the 17 September 2019, N PRM to correct two dates in NHTSA's phase -in reporting requirements 
for FMVSS No. 141 is no longer needed. That change was addressed previously by the agency's 1 
September 2020, interim final rule that extended the FMVSS No. 141 compliance deadline and 
phase-in dates by six months. The interim final rule included adjustments to NHTSA's reporting 
dates, superseding the need for the proposed corrections.  
DATES: This final rule is effective on 12 August 2022.
