Mixed sound footage focusing primarily on the use of triple trailers (a single semi-tractor pulling three separate trailers linked together in tandem) on Oregon's roads. The film includes ground and aerial footage of large trucks operating on a variety of road types; log trucks loading, hauling and unloading; and tractors hitching and unhitching from trailers. Sound segments consist of unnamed narrators discussing the specifics of delivery operations in the Portland area; the design and testing of high horsepower tractors needed to pull triple trailer; legislative action related to the testing, requirements and permitting for triple trailers; the economic efficiencies of using triple trailers; and a truck driver commenting on the experience of operating a triple trailer and his union's position toward the work.
