Tacoma clean truck stickers valid until Jan. 1, 2018

The NWSA's Clean Truck Program requires trucks serving Seattle and Tacoma terminals to have newer, cleaner-burning engines to reduce diesel emissions.

The South Harbor program uses stickers to identify compliant trucks. Stickers that expired Dec. 31, 2015 are still valid. Drivers do not need to register for a new sticker. All Tacoma stickers will be valid until Jan. 1, 2018. 

The deadline for drayage trucks to comply with the Clean Truck Program's requirement of 2007 or newer model year engines has been extended to Jan. 1, 2018. Learn more about our Clean Truck Program.
