Supplemental notice of proposed rulemaking (SNPRM).

In 2016, NHTSA published a notice of proposed rulemaking (NPRM) to amend our regulations, "Make Inoperative Exemptions, Vehicle Modifications to Accommodate People With Disabilities," to include a new exemption relating to the Federal motor vehicle safety standard (FMVSS) for roof crush resistance. The exemptions facilitate the mobility of drivers and passengers with physical disabilities. This SNPRM expands the scope of NHTSA's 2016 NPRM in two ways. First, it grants a petition from Bruno Independent Living Aids, Inc., and proposes to include in part 595 an exemption relating to the rear visibility requirements in FMVSS No. 111. Second, in response to an inquiry from Enterprise Holdings Co. (Enterprise), this document proposes to permit rental car companies to make inoperative a knee bolster air bag, on a temporary basis, to permit the temporary installation of hand controls to accommodate persons with physical disabilities seeking to rent the vehicle.
