ATV Noise Laws
New 96 Decibel ATV rule takes effect March 1, 2006
A new rule provides law enforcement with a field-friendly stationary procedure for testing an ATV’s compliance with the 96 decibel limit that was established in 2003. The previous law made it illegal for a person to manufacture, sell, rent or operate an ATV that emits noise in excess of 96 decibels. Excessively loud exhausts are illegal and hurt the ATV program in Wisconsin. Illegal exhausts generate complaints and can result in the closure of riding areas.
The test procedure has been adopted by the Society of Automotive Engineers (SAE) as a means to measure ATV noise levels using a nationally, consistent method. The SAE standard J1287 describes a test method and illustrates motorcycle testing; however, the test procedure is also used for ATVs. In brief, stationary ATV exhaust noise is measured at 20 inches away with the ATV throttled up to ½ the machine’s maximum RPMs.
