If you are into 4-wheeler riding, you are aware that there are many laws and prohibitions that are involved with 4-wheeler riding and one such law involves noise regulations. The level of compliance depends on the year your 4-wheeler was manufactured in. For any ordinary 4-wheeler that was manufactured before January 1, 1986, the limit of noise decibels is 101. For any ordinary 4-wheeler Manufactured on or after January 01, 1986, the limit of noise decibels is 96. Considering that the average decibel of a baby crying is 110, that will give you an idea of the level of noise your 4-wheeler can put out.
If you're 4-wheeler is considered a "competition" vehicle, then if it was manufactured before January 1, 1998, the decibels may reach up to 101. If your competition 4-wheeler was produced however, on or after January 01, 1998, the decibels still must be no more than 96.
A 4-wheeler is considered a "competition" vehicle only if the 4-wheeler was not manufactured under the standards of The California emission standards or to comply with the EPA noise standards.
