N.J.S.A. 39:3-70 requires every combustion-engine vehicle to have a muffler in good working order and constant operation to prevent excessive or unusual noise, and prohibits muffler cut-outs or bypasses. Separately, the NJDEP model ordinance towns adopt bars vehicular music amplification that is plainly audible 25 feet away overnight or 50 feet away during the day. Enforcement is by state and municipal police and, for the noise standard, certified Noise Control Officers. There is no Essex County-issued vehicle-noise citation outside its parks.
