It shall be unlawful for any person to permit any truck, automobile or motorcycle engine to idle for more than ninety consecutive seconds while that vehicle is parked on a city street.
Full Breakdown
CVC §27150 requires every motor vehicle to have an adequate muffler in constant operation to prevent excessive or unusual noise; §27151 prohibits exhaust modifications that amplify noise. Santa Cruz Police enforce CVC standards through fix-it tickets and CHP referee referral. Locally, §10.40.270 makes it unlawful to idle a truck, automobile, or motorcycle engine longer than 90 seconds while parked on a city street, with exceptions for emergency vehicles, defrosting windows, and work-related uses (lifts, winches, cranes).
Violations & Fines
Idling beyond 90 seconds is a citable offense. CVC exhaust violations are equipment ('fix-it') tickets that escalate if uncorrected.
