King County and Washington state limit unnecessary diesel idling, particularly near schools, hospitals, and Metro bus bases, to protect air quality in the central Puget Sound airshed.
Washington Administrative Code 173-422A and county fleet policies cap diesel truck and bus idling at five minutes in most situations, with longer allowances only for safety, defrosting, or active loading. King County Metro and Public Health Seattle & King County run anti-idling programs at school zones and transit centers. The Puget Sound Clean Air Agency enforces regional idling rules and investigates complaints about idling commercial vehicles.
Violations of WAC 173-422A diesel idling rules can result in Puget Sound Clean Air Agency civil penalties, with notices first and escalating fines for repeat or commercial offenders.
