Legal Basis</HD> Under 49 U.S.C. 31136(a), DOT is required to “prescribe minimum safety standards for commercial motor vehicles. At a minimum, the regulations shall ensure that—(1) commercial motor vehicles are maintained, equipped, loaded, and operated safely, (2) the responsibilities imposed on operators of commercial motor vehicles do not impair their ability to operate the vehicles safely; (3) the physical conditions of operators of commercial motor vehicles is adequate to enable them to operate the vehicles safely . . .; (4) the operation of commercial motor vehicles does not have a deleterious effect on the physical condition of the operators; and (5) an operator of a commercial motor vehicle is not coerced by a motor carrier, shipper, receiver, or transportation intermediary to operate a commercial motor vehicle in violation of a regulation promulgated under this section, or chapter 51 or chapter 313 of this title.” This NPRM is based on the authority of 49 U.S.C. 31136(a)(1) to ensure that CMVs are equipped and operated safely. It does not implicate the driver-centered requirements of 49 U.S.C. 31136(a)(2) through (4). Because this NPRM would not impose any requirement on motor carriers, there is no obvious risk of coercion related to this rulemaking to which a driver might be subjected. The Administrator of FMCSA is delegated authority under 49 CFR 1.87 to carry out the functions vested in the Secretary of Transportation by 49 U.S.C. chapters 311, 313, and 315 as they relat ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ Preview showing 10k of 26k characters.
