Motorcycle Noise Levels Cannot Be Controlled Locally In New Hampshire

There are statewide laws in New Hampshire that prohibit
motorcyclists from driving bikes that make noise above a certain
level, but some towns have attempted to make these restrictions
even tighter. The state limits the volume a bike can reach to 106
decibels, but when the town of North Hampton attempted to pare this
level down to 80 decibels, the owner of the local
Harley-Davidson shop filed suit against the township. The
case ended up in favor of the complainant, ruling that towns and
cities are no longer able to impose such legislation locally.
"If each town in New Hampshire had the authority to enact different
noise emission ordinances, the state would be subject to a
checkerboard pattern of laws," ruled Kenneth McHugh, the Rockingham
County Superior Court Judge, according to the news source. "For
example, a motorcyclist who complies with the state noise emission
limit could be precluded from driving through a town because that
town enacted a lower noise emission limit than the state."
The court also pointed out that the NH House of Representatives
Transportation Committee recently rejected a bill that proposed
limitations close to those imposed in North Hampton last year.
Riders who exceed the noise limits may be subject to suspended
registrations, according to the news publication.
