Vehicle noise in unincorporated Ventura County is regulated by California Vehicle Code Section 27007 (95 dBA modified exhaust limit) and the county's general noise ordinance. The Ventura County Sheriff enforces vehicle noise through traffic stops and complaint response.
Vehicle noise in unincorporated Ventura County is primarily governed by the California Vehicle Code. CVC Section 27007 limits exhaust noise to 95 dBA for modified vehicles. Excessive vehicle noise in residential areas, including revving engines, loud stereos audible beyond 50 feet, and tire squealing, can be cited under both state law and the county noise ordinance. The Ventura County Sheriff's Office handles enforcement through traffic patrols and complaint response. Modified exhaust systems exceeding state limits receive fix-it tickets. Off-highway vehicle noise on private property in rural areas like Lockwood Valley and Piru may be subject to different standards.
Modified exhaust exceeding 95 dBA: CVC 27007 fix-it ticket ($25 correctable, $197 if not). Loud stereo audible 50+ feet: CVC citation ($25-$197). Disturbing the peace with vehicle noise: Penal Code 415 ($250-$1,000). Street racing: misdemeanor with $1,000 fine, 90-day license suspension, and 30-day vehicle impound.
