Previously: Under New Jersey law, it is illegal to operate a vehicle sound system that is plainly audible at 50 feet or more. [Accurate]: This was read aloud on air from a search result, and it holds up. New Jersey's state model noise ordinance, which local noise ordinances must match to get state approval, says car music systems may not be plainly audible at 50 feet or more between 8 a.m. and 10 p.m., with a stricter 25 feet at night. A 2023 state law also set fines of $250 to $500 for a first offense when a car sound system breaks those noise standards. Finding that the current state model ordinance or the 2023 law uses a different distance would prove this wrong.

Now: Under New Jersey law, it is illegal to operate a vehicle sound system that is plainly audible at 50 feet or more. [Distorted]: New Jersey law penalizes vehicle sound systems that violate noise standards adopted under the Noise Control Act, but the cited plainly-audible distance comes from a model ordinance that municipalities adopt. Without a municipality, it is too broad to state that the 50-foot rule applies uniformly throughout New Jersey. The transcript also should not imply that every sound system audible at that distance is a statewide violation.

The cited 50-foot standard is in NJDEP model ordinance guidance for municipal adoption, while the state statute ties penalties to applicable standards and rules.
