Clean Diesel Truck Video Training

Clean diesel trucks (with 2007 or newer engines) are ten times cleaner than older diesel trucks. But they also have complicated pollution control systems. Understanding how newer trucks and their pollution control systems work is important to avoiding expensive engine repairs. 

This video training course will guide you through the differences between older diesel trucks and newer, cleaner diesel trucks. It will also show you how to take care of a clean diesel truck.

Diesel pollution is the largest air toxic and cancer risk in the Puget Sound region, especially near the Ports of Seattle and Tacoma. By replacing older diesel trucks with newer, cleaner trucks we are helping to reduce harmful air pollution in the communities that need it the most.
