Full Breakdown
No driver operating a vehicle within city limits may idle the engine more than two minutes. The rule applies on public property and on private property open to the public, unless the owner posts a city-approved idle-time sign at a drive-through or adopts a city-approved idle reduction policy. Exceptions cover stops for traffic signals or police direction, driver/passenger health and safety, emergency and law enforcement equipment, repair or maintenance, manufacturer-recommended warm-up for turbocharged heavy trucks, and auxiliary equipment like refrigeration units, lifts, or pumps (but not heaters or A/C).
Violations & Fines
First offense is a civil warning with no fine. Subsequent offenses draw a civil fine equal to the overtime-parking penalty under § 12.56.190.
