Maine has just adopted a new standard to measure the noise your motorcycle makes. Maine is just one state that has a law against motorcycle noise, but they are the first in the region to adopt the SAE J2825 standard.
Which is a good thing, sort of.
The Society of Automotive Engineers (SAE) J2825 stationary sound testing procedure, "Measurement of Exhaust Sound Pressure Levels of Stationary On-Highway Motorcycles," was created with the help of the Motorcycle Industry Council in May 2009. It is a very accurate way of measuring motorcycle noise and should help to make sure that only offenders are prosecuted for tickets.
But the noise standard won’t stop anyone from receiving a ticket. Police officers will, more or less, guess as a motorcycle drives by. If you get a ticket, you can bring your bike into a certified testing facility. If your motorcycle falls within the legal limits, the certified test can be used as proof that you don’t deserve a ticket.
Which is great, I guess. But it’s still a hassle.
"This new law is good news for responsible motorcyclists who ride in Maine because it provides an objective way to prove that a motorcycle doesn't violate the state's sound law, rather than relying on subjective judgments," said Imre Szauter, AMA government affairs manager. "We applaud the state of Maine -- the first in the nation -- for adopting the SAE J2825 standard."
So the good news is that when you receive a bogus ticket, you can prove that it’s a bogus ticket. The bad news is that you’re still going to get bogus tickets.
