Full Breakdown
Orange County Codified Ordinances § 3-8-48 makes it unlawful to operate a vehicle in unincorporated county territory in a manner reasonably likely to disturb the peace or quiet of a neighborhood or person through noise, dust, smoke or fumes: covering blaring stereos, revved engines and loud exhaust as squarely as it covers dust or fumes from off-roading. The rule sits in the Code's property-protection title alongside trespass and land-nuisance provisions, separate from the zone-based exterior noise limits in § 4-6-5. No specific fine is set for this section, so the Code's general penalty in § 1-1-34 applies: a misdemeanor punishable by up to $1,000 and up to six months in county jail.
Violations & Fines
A first violation is a misdemeanor under the Code's general penalty: up to $1,000 in fines and up to six months in county jail; prosecutors may instead charge it as a lesser infraction.
