Among the rules and regulations that are strictly enforced, noise regulations are among the top of the list. The allowable noise limit depends upon what year your ATV was manufactured. For any ordinary ATV that was manufactured before January 1, 1986, the limit of noise decibels is 101. For any ordinary ATV Manufactured on or after January 01, 1986, the limit of noise decibels is only 96. The average decibel of a baby crying is 110 to give you an idea of how loud that many decibels is.
If you're ATV is considered a "competition" vehicle and it was manufactured before January 1, 1998, the decibels may reach up to 101. If your competition ATV was produced however, on or after January 01, 1998, the decibels still must be no more than 96.
An ATV is considered a "competition" vehicle only if the ATV was not manufactured under the standards of The California emission standards or to comply with the EPA noise standards. If you're interested in finding out the procedures of how testing is done, you can visit the website of California state parks off-highway vehicle recreation division at: www.ohv.parks.ca.gov.
Take the time to get yourself educated. By staying within the laws and regulations, your next ride on your ATV will be the best one yet!
