The State of California is considering leveraging enhanced surveillance to increase the number of motorists it can fine for noise violations. While the rules allowing the state to penalize motorists for emitting too much sound have existed for years, they were amped up slightly in 2019 when Assembly Bill 1824 went into effect and established the limits for what’s allowed today. The updated rules also required police to immediately fine anyone driving an automobile that’s emitting noise measured above 95 decibels, rather than issue a fix-it ticket. Motorcycles, which can occasionally exceed 95 dB in their stock format if they’re older, are limited to just 80 dB.
But determining when and where someone broke the rule is difficult, especially considering measurements were originally supposed to be taken under the Society of Automotive Engineers (SAE) test procedure J1169, so the coastal region is on the cusp of launching a new program that would introduce microphone-equipped traffic cameras similar to what we’ve already seen in New York and the United Kingdom. California leadership believes that an automated system would result in greater levels of enforcement by effectively mimicking the speed camera formula and applying it to vehicular noise violations.
