SUMMARY:

Based on the agency's evaluation, NHTSA denies a petition for rulemaking from Mr. David K. Aberizk, P.E., of Integrated Consultants Incorporated, who requests the development of safety standards for a driver-activated vehicle regenerative braking interface with distinct rear lighting indication. The petitioner claims that the recommended changes to the relevant safety standards would allow vehicle manufacturers to better utilize the regenerator technology to increase vehicle efficiency. NHTSA finds that some features of the suggested concept are not prohibited by existing Federal motor vehicle safety standards (FMVSS) and notes that Mr. Aberizk did not demonstrate how the other features address a motor vehicle safety need. FMVSS Nos. 108 and 135 currently specify performance requirements relevant to certain permitted technologies identified in the petition.
