The Federal Motor Carrier Safety Administration is seeking comment on the merits of a petition for rulemaking filed by the Truck Manufacturers Association. The trade association has petitioned FMCSA to amend its regulations to eliminate turbochargers from the list of equipment considered to be noise-dissipative devices.

The truck makers’ group contends that virtually all trucks now are equipped with turbochargers. Hence, these trucks cannot be cited for failure to meet the visual exhaust system inspection requirements of FMCSA’s safety regulations if they have no muffler.

Comments must be received by Oct. 25. For a copy of the entire rulemaking, go to and search Docket No. 24065.
