Full Breakdown
Section 17-13 sets sound-level ceilings by vehicle weight and road speed. For any combination of vehicles with a manufacturer's gross vehicle weight rating or gross combination weight rating of 10,000 pounds or more operated by an interstate motor carrier, the limit is 91 dB where the posted speed is 35 mph or less and 95 dB above that, measured at least 35 feet from the centerline of the traveled lane. Every other motor vehicle or towed combination is capped at 76 dB at 35 mph or below and 80 dB above that speed, measured at least 25 feet from the nearest monitored lane at a height of at least four feet off the surface.
These limits apply to the total noise a vehicle produces and don't limit separate enforcement of the chapter's muffler rules. Section 17-13 also requires every motor vehicle's exhaust system to be free of defects that affect sound reduction, fitted with a muffler or other noise-dissipative device, and free of any cut-out, bypass, or similar device that would let exhaust bypass the muffler. A vehicle that meets the decibel table but runs a cut-out or a defective muffler is still out of compliance with the equipment half of the section.
Violations & Fines
Operating a motor vehicle above the applicable decibel limit in Section 17-13, or with a defective, missing, or bypassed exhaust or muffler system, is enforceable under the chapter's general noise misdemeanor provisions in Section 17-8. Officers measure noise at the prescribed 25-foot or 35-foot distance and four-foot height before citing a moving vehicle, while a defective or cut-out exhaust can be cited on inspection alone, without a decibel reading.
