Vehicle Noise: Vacaville vs Vallejo
How do vehicle noise rules compare between Vacaville, CA and Vallejo, CA?
Vacaville, CA
Solano County
Vehicle noise on Vacaville streets is governed primarily by the California Vehicle Code rather than by a dedicated local muffler ordinance. CVC §27150 requires every motor vehicle to be equipped with an adequate muffler in constant operation; CVC §27151 prohibits modifying the exhaust to amplify noise above CHP standards (95 dB(A) by SAE J1169 for passenger vehicles). Vacaville's own Chapter 8.10 nuisance standards apply to non-roadway vehicle noise (e.g., revving in driveways, loud car stereos at residences).

Vacaville FAQ
Are loud exhaust systems illegal in Vacaville?
Yes, under California law. California Vehicle Code §27150 requires every motor vehicle to have an adequate muffler in constant operation, and §27151 prohibits modifying the exhaust to amplify noise. For passenger cars and light trucks, CHP measures against a 95 dB(A) SAE J1169 standard. Vacaville Police enforce these state-law violations on city streets.
Can I be cited for revving my car in my driveway in Vacaville?
Possibly. Once the vehicle is off the public roadway, Vacaville Municipal Code Chapter 8.10 applies and treats noise that disturbs a reasonable person of normal sensitivity as a public nuisance. Repeated, late-night, or particularly loud revving near an occupied residence can be cited as a nuisance, with the construction/commercial-equipment quiet windows providing a clear bright line at night.
