Federal Motor Vehicle Safety Standards No. 224; Rear Impact Protection

الملخص

In this document, NHTSA proposes to amend the Federal motor vehicle safety standard (FMVSS) No. 224, "Rear impact protection," to exclude road construction controlled horizontal discharge semitrailers (RCC horizontal discharge trailers) from the standard. The agency has tentatively concluded that the installation of rear impact guards (underride guards), as required by FMVSS No. 224, on RCC horizontal discharge trailers is impracticable due to the unique design and purpose of such vehicles.
