SOUND LEVELS AND TESTS
Loud snowmobiles and OHRVs are a primary cause of
complaints from landowners and other trail users. Vehicles
powered by “two stroke” engines are the biggest offenders.
All operators are encouraged to ride quiet vehicles. It is illegal
to modify an exhaust system in any way that increases
the noise level.
Snowmobile noise levels must comply with the manufacturer
specifications as contained in the requirements of the
Snowmobile Safety and Certification Committee
approval.Trail bikes and ATVs cannot emit noise levels that
exceed 96 decibels.
OHRVs designed for “closed course competition” may only
be used at OHRV competitions, unless the OHRV is modified
to meet all equipment requirements including muffler, spark
arrestor and noise emissions.
Snowmobile and OHRV operators must submit to a sound
level test when requested to do so by a law enforcement officer
