Washington state law caps non-essential diesel truck idling at five minutes, and Tacoma enforces tighter Port-area idling rules through the Northwest Ports Clean Air Strategy.
RCW 70A.15 and Puget Sound Clean Air Agency Regulation III restrict commercial diesel idling to five minutes per hour in most cases, with exemptions for traffic, sleeper cabs in extreme weather, and active loading. The Port of Tacoma, as part of the Northwest Seaport Alliance, follows the Northwest Ports Clean Air Strategy 2020 with stricter targets for drayage trucks, harbor craft, and cargo handling equipment. Tacoma supports the strategy through its Climate Action Plan and zoning around the Tideflats. Enforcement is by the Puget Sound Clean Air Agency, not the city directly, but residents can file complaints.
Idling beyond five minutes draws state air-quality violations from the Puget Sound Clean Air Agency, with fines beginning around 1,000 dollars per incident.
