Compliance with Interstate Motor Carrier Noise Emission Standards: Exhaust Systems
Notice; request for comments.
FMCSA requests public comment on the merits of a petition for rulemaking filed by the Truck Manufacturers Association. This trade association, whose members include all of the major North American manufacturers of medium and heavy-duty trucks, has petitioned FMCSA to amend the Federal Motor Carrier Safety Regulations to eliminate turbochargers from the list of equipment considered to be noise dissipative devices. The Truck Manufacturers Association contends that virtually all trucks are now 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.
