In New Hampshire motorcycle sound testing will now be conducted using instruments, like the one pictured below, that provide roadside, objective measurements. This is in contrast to the subjective test which most motorcycles are subjected to throughout the country. New Hampshire’s SAE J2825 authorizes roadside testing using measurement of sound exhaust sound pressure levels of stationary bikes. This test will be administered before any ticket can be issued.
This new law is good news for responsible motorcycle riders as they will now have ways to prove that their bikes meet legal standards. Hopefully, as this technology becomes streamlined, more states will adopt similar laws.
The New Hampshire law takes effect January 1, 2013.
